一、预约下单前端

由于预约下单后台 api 接口相对复杂，我们先实现前端，前端配合调试 api 接口

1. 封装 api 请求

添加 /api/order/orderInfo.js 文件，定义下单接口

import request from '@/utils/request'

const api_name = `/api/order/orderInfo`

export default {
	submitOrder(scheduleId, patientId) {
		return request({
			url: `${api_name}/auth/submitOrder/${scheduleId}/${patientId}`,
			method: 'post'
		})
	}
}

2. 页面修改

在 /pages/hosp/booking.vue 组件完善下单方法

submitOrder() {
    if(this.patient.id == null) {
    	return this.$message.error('请选择就诊人') 
    }
    // 防止重复提交
    if(this.submitBnt == '正在提交...') {
    	return this.$message.error('重复提交')
    }

    this.submitBnt = '正在提交...'
    orderInfoApi.submitOrder(this.scheduleId, this.patient.id).then(response => {
	    let orderId = response.data
	    window.location.href = '/order/show?orderId=' + orderId
    }).catch(e => {
   		this.submitBnt = '确认挂号'
    })
},

二、后端逻辑

1. 需求分析

A、订单表结构

B、下单分析

下单参数：就诊人 id 与排班 id

• 下单我们要获取就诊人信息
• 获取排班下单信息与规则信息
• 获取医院签名信息，然后通过接口去医院预约下单

下单成功更新排班信息与发送短信

2. 搭建 service-order 模块

A、搭建service-order模块

搭建过程参考service-user模块

B、修改配置

修改pom.xml，引入依赖

<dependencies>
    <dependency>
        <groupId>com.fancy.yygh</groupId>
        <artifactId>service-cmn-client</artifactId>
        <version>0.0.1-SNAPSHOT</version>
    </dependency>
</dependencies>

添加配置文件 application.properties

# 服务端口
server.port=8206
# 服务名
spring.application.name=service-order
# 环境设置：dev、test、prod
spring.profiles.active=dev

# mysql数据库连接
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://192.168.38.130:3306/yygh_hosp?characterEncoding=utf-8&useSSL=false
spring.datasource.username=root
spring.datasource.password=root

#返回json的全局时间格式
spring.jackson.date-format=yyyy-MM-dd HH:mm:ss
spring.jackson.time-zone=GMT+8

spring.data.mongodb.uri=mongodb://192.168.44.165:27017/yygh_hosp

# nacos服务地址
spring.cloud.nacos.discovery.server-addr=127.0.0.1:8848

#rabbitmq地址
spring.rabbitmq.host=192.168.44.165
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest

C、启动类

@SpringBootApplication
@EnableDiscoveryClient
@EnableFeignClients(basePackages = {"com.fancy.yygh"})
public class ServiceOrderApplication {
    public static void main(String[] args) {
        SpringApplication.run(ServiceOrderApplication.class, args);
    }
}

D、配置网关

#设置路由id
spring.cloud.gateway.routes[6].id=service-order
#设置路由的uri
spring.cloud.gateway.routes[6].uri=lb://service-order
#设置路由断言,代理servicerId为auth-service的/auth/路径
spring.cloud.gateway.routes[6].predicates= Path=/*/order/**

3. 添加订单基础类

A、添加 model

说明：由于实体对象没有逻辑，我们已经统一导入com.fancy.yygh.model.order.OrderInfo

B、添加 Mapper

添加 com.fancy.yygh.order.mapper.OrderInfoMapper

public interface OrderInfoMapper extends BaseMapper<OrderInfo> {
}

C、添加 service 接口及实现类

添加 com.fancy.yygh.order.service.OrderService 接口

public interface OrderService extends IService<OrderInfo> {
    //保存订单
    Long saveOrder(String scheduleId, Long patientId);
}

添加 com.fancy.yygh.order.service.impl.OrderServiceImpl 接口实现

@Service
public class OrderServiceImpl extends ServiceImpl<OrderMapper, OrderInfo> implements OrderService {
    //保存订单
    @Override
    public Long saveOrder(String scheduleId, Long patientId) {
        return null;
    }
}

D、添加 controller
添加 com.fancy.yygh.order.api.OrderApiController 类

@Api(tags = "订单接口")
@RestController
@RequestMapping("/api/order/orderInfo")
public class OrderApiController {

    @Autowired
    private OrderService orderService;

    @ApiOperation(value = "创建订单")
    @PostMapping("auth/submitOrder/{scheduleId}/{patientId}")
    public Result submitOrder(
            @ApiParam(name = "scheduleId", value = "排班id", required = true)
            @PathVariable String scheduleId,
            @ApiParam(name = "patientId", value = "就诊人id", required = true)
            @PathVariable Long patientId) {
        return Result.ok(orderService.saveOrder(scheduleId, patientId));
    }
}

4. 封装 Feign 调用获取就诊人接口

A、获取就诊人信息 api 接口

操作模块：service-user

在 PatientApiController 类添加方法

@ApiOperation(value = "获取就诊人")
@GetMapping("inner/get/{id}")
public Patient getPatientOrder(
        @ApiParam(name = "id", value = "就诊人id", required = true)
        @PathVariable("id") Long id) {
    return patientService.getById(id);
}

B、搭建 service-user-client 模块

① 搭建 service-user-client 模块
搭建过程如 service-cmn-client 模块

② 添加 Feign 接口类

@FeignClient(value = "service-user")
@Repository
public interface PatientFeignClient {
    //获取就诊人
    @GetMapping("/api/user/patient/inner/get/{id}")
    Patient getPatient(@PathVariable("id") Long id);
}

5. 封装 Feign 调用获取排班下单信息接口

A、获取排班下单信息 api 接口

操作模块：service-hosp

① 添加service接口与实现

在ScheduleService类添加接口

//根据排班id获取预约下单数据
ScheduleOrderVo getScheduleOrderVo(String scheduleId);

public ScheduleOrderVo getScheduleOrderVo(String scheduleId) {
    ScheduleOrderVo scheduleOrderVo = new ScheduleOrderVo();
    //排班信息
    Schedule schedule = baseMapper.selectById(scheduleId);
    if(null == schedule) {
        throw new YyghException(ResultCodeEnum.PARAM_ERROR);
    }

    //获取预约规则信息
    Hospital hospital = hospitalService.getByHoscode(schedule.getHoscode());
    if(null == hospital) {
        throw new YyghException(ResultCodeEnum.DATA_ERROR);
    }
    BookingRule bookingRule = hospital.getBookingRule();
    if(null == bookingRule) {
        throw new YyghException(ResultCodeEnum.PARAM_ERROR);
    }

    scheduleOrderVo.setHoscode(schedule.getHoscode());
    scheduleOrderVo.setHosname(hospitalService.getHospName(schedule.getHoscode()));
    scheduleOrderVo.setDepcode(schedule.getDepcode());
    scheduleOrderVo.setDepname(departmentService.getDepName(schedule.getHoscode(), schedule.getDepcode()));
    scheduleOrderVo.setHosScheduleId(schedule.getHosScheduleId());
    scheduleOrderVo.setAvailableNumber(schedule.getAvailableNumber());
    scheduleOrderVo.setTitle(schedule.getTitle());
    scheduleOrderVo.setReserveDate(schedule.getWorkDate());
    scheduleOrderVo.setReserveTime(schedule.getWorkTime());
    scheduleOrderVo.setAmount(schedule.getAmount());

    //退号截止天数（如：就诊前一天为-1，当天为0）
    int quitDay = bookingRule.getQuitDay();
    DateTime quitTime = this.getDateTime(new DateTime(schedule.getWorkDate()).plusDays(quitDay).toDate(), bookingRule.getQuitTime());
    scheduleOrderVo.setQuitTime(quitTime.toDate());

    //预约开始时间
    DateTime startTime = this.getDateTime(new Date(), bookingRule.getReleaseTime());
    scheduleOrderVo.setStartTime(startTime.toDate());

    //预约截止时间
    DateTime endTime = this.getDateTime(new DateTime().plusDays(bookingRule.getCycle()).toDate(), bookingRule.getStopTime());
    scheduleOrderVo.setEndTime(endTime.toDate());

    //当天停止挂号时间
    DateTime stopTime = this.getDateTime(new Date(), bookingRule.getStopTime());
    scheduleOrderVo.setStartTime(startTime.toDate());
    return scheduleOrderVo;
}

② 添加 controller 方法

    wrapper.eq("hoscode",hoscode);
    HospitalSet hospitalSet = baseMapper.selectOne(wrapper);
    if(null == hospitalSet) {
        throw new YyghException(ResultCodeEnum.HOSPITAL_OPEN);
    }
    SignInfoVo signInfoVo = new SignInfoVo();
    signInfoVo.setApiUrl(hospitalSet.getApiUrl());
    signInfoVo.setSignKey(hospitalSet.getSignKey());
    return signInfoVo;
}

③ 添加 controller方法

6. 实现下单接口

操作模块：service-order

A、引入依赖

<dependencies>
    <dependency>
        <groupId>com.fancy.yygh</groupId>
        <artifactId>service-cmn-client</artifactId>
        <version>0.0.1-SNAPSHOT</version>

        <artifactId>service-user-client</artifactId>
        <version>0.0.1-SNAPSHOT</version>
    </dependency>
</dependencies>

B、封装下单工具类

封装 HttpRequestHelper 类，添加签名请求方法

public class HttpRequestHelper {
    /**
     *
     * @param paramMap
     * @return
     */
    public static Map<String, Object> switchMap(Map<String, String[]> paramMap) {
        Map<String, Object> resultMap = new HashMap<>();
        for (Map.Entry<String, String[]> param : paramMap.entrySet()) {
            resultMap.put(param.getKey(), param.getValue()[0]);
        }
        return resultMap;
    }

    /**
     * 请求数据获取签名
     * @param paramMap
     * @param signKey
     * @return
     */
    public static String getSign(Map<String, Object> paramMap, String signKey) {
        if(paramMap.containsKey("sign")) {
            paramMap.remove("sign");
        }
        TreeMap<String, Object> sorted = new TreeMap<>(paramMap);
        StringBuilder str = new StringBuilder();
        for (Map.Entry<String, Object> param : sorted.entrySet()) {
            str.append(param.getValue()).append("|");
        }
        str.append(signKey);
        log.info("加密前：" + str.toString());
        String md5Str = MD5.encrypt(str.toString());
        log.info("加密后：" + md5Str);
        return md5Str;
    }

    /**
     * 签名校验
     * @param paramMap
     * @param signKey
     * @return
     */
    public static boolean isSignEquals(Map<String, Object> paramMap, String signKey) {
        String sign = (String)paramMap.get("sign");
        String md5Str = getSign(paramMap, signKey);
        if(!sign.equals(md5Str)) {
            return false;
        }
        return true;
    }

    /**
     * 获取时间戳
     * @return
     */
    public static long getTimestamp() {
        return new Date().getTime();
    }

    /**
     * 封装同步请求
     */
    public static JSONObject sendRequest(Map<String, Object> paramMap, String url){
        String result = "";
        try {
            //封装post参数
            StringBuilder postdata = new StringBuilder();
            for (Map.Entry<String, Object> param : paramMap.entrySet()) {
                postdata.append(param.getKey()).append("=")
                        .append(param.getValue()).append("&");
            }
            log.info(String.format("--> 发送请求：post data %1s", postdata));
            byte[] reqData = postdata.toString().getBytes("utf-8");
            byte[] respdata = HttpUtil.doPost(url,reqData);
            result = new String(respdata);
            log.info(String.format("--> 应答结果：result data %1s", result));
        } catch (Exception ex) {
            ex.printStackTrace();
        }
        return JSONObject.parseObject(result);
    }
}

C、实现下单接口

@Service
public class OrderServiceImpl extends ServiceImpl<OrderMapper, OrderInfo> implements OrderService {

    @Autowired
    private PatientFeignClient patientFeignClient;
    @Autowired
    private HospitalFeignClient hospitalFeignClient;

    //保存订单
    @Override
    public Long saveOrder(String scheduleId, Long patientId) {
        Patient patient = patientFeignClient.getPatient(patientId);
        if(null == patient) {
            throw new YyghException(ResultCodeEnum.PARAM_ERROR);
        }
        ScheduleOrderVo scheduleOrderVo = hospitalFeignClient.getScheduleOrderVo(scheduleId);
        if(null == scheduleOrderVo) {
            throw new YyghException(ResultCodeEnum.PARAM_ERROR);
        }
        //当前时间不可以预约
        if(new DateTime(scheduleOrderVo.getStartTime()).isAfterNow() || new DateTime(scheduleOrderVo.getEndTime()).isBeforeNow()) {
            throw new YyghException(ResultCodeEnum.TIME_NO);
        }
        SignInfoVo signInfoVo = hospitalFeignClient.getSignInfoVo(scheduleOrderVo.getHoscode());
        if(null == scheduleOrderVo) {
            throw new YyghException(ResultCodeEnum.PARAM_ERROR);
        }
        if(scheduleOrderVo.getAvailableNumber() <= 0) {
            throw new YyghException(ResultCodeEnum.NUMBER_NO);
        }
        OrderInfo orderInfo = new OrderInfo();
        BeanUtils.copyProperties(scheduleOrderVo, orderInfo);
        String outTradeNo = System.currentTimeMillis() + ""+ new Random().nextInt(100);
        orderInfo.setOutTradeNo(outTradeNo);
        orderInfo.setScheduleId(scheduleId);
        orderInfo.setUserId(patient.getUserId());
        orderInfo.setPatientId(patientId);
        orderInfo.setPatientName(patient.getName());
        orderInfo.setPatientPhone(patient.getPhone());
        orderInfo.setOrderStatus(OrderStatusEnum.UNPAID.getStatus());
        this.save(orderInfo);

        Map<String, Object> paramMap = new HashMap<>();
        paramMap.put("hoscode",orderInfo.getHoscode());
        paramMap.put("depcode",orderInfo.getDepcode());
        paramMap.put("hosScheduleId",orderInfo.getScheduleId());
        paramMap.put("reserveDate",new DateTime(orderInfo.getReserveDate()).toString("yyyy-MM-dd"));
        paramMap.put("reserveTime", orderInfo.getReserveTime());
        paramMap.put("amount",orderInfo.getAmount());
        paramMap.put("name", patient.getName());
        paramMap.put("certificatesType",patient.getCertificatesType());
        paramMap.put("certificatesNo", patient.getCertificatesNo());
        paramMap.put("sex",patient.getSex());
        paramMap.put("birthdate", patient.getBirthdate());
        paramMap.put("phone",patient.getPhone());
        paramMap.put("isMarry", patient.getIsMarry());
        paramMap.put("provinceCode",patient.getProvinceCode());
        paramMap.put("cityCode", patient.getCityCode());
        paramMap.put("districtCode",patient.getDistrictCode());
        paramMap.put("address",patient.getAddress());
        //联系人
        paramMap.put("contactsName",patient.getContactsName());
        paramMap.put("contactsCertificatesType", patient.getContactsCertificatesType());
        paramMap.put("contactsCertificatesNo",patient.getContactsCertificatesNo());
        paramMap.put("contactsPhone",patient.getContactsPhone());
        paramMap.put("timestamp", HttpRequestHelper.getTimestamp());
        String sign = HttpRequestHelper.getSign(paramMap, signInfoVo.getSignKey());
        paramMap.put("sign", sign);
        JSONObject result = HttpRequestHelper.sendRequest(paramMap, signInfoVo.getApiUrl()+"/order/submitOrder");
        
        if(result.getInteger("code") == 200) {
            JSONObject jsonObject = result.getJSONObject("data");
            //预约记录唯一标识（医院预约记录主键）
            String hosRecordId = jsonObject.getString("hosRecordId");
            //预约序号
            Integer number = jsonObject.getInteger("number");;
            //取号时间
            String fetchTime = jsonObject.getString("fetchTime");;
            //取号地址
            String fetchAddress = jsonObject.getString("fetchAddress");;
            //更新订单
            orderInfo.setHosRecordId(hosRecordId);
            orderInfo.setNumber(number);
            orderInfo.setFetchTime(fetchTime);
            orderInfo.setFetchAddress(fetchAddress);
            baseMapper.updateById(orderInfo);
            //排班可预约数
            Integer reservedNumber = jsonObject.getInteger("reservedNumber");
            //排班剩余预约数
            Integer availableNumber = jsonObject.getInteger("availableNumber");
            //发送mq信息更新号源和短信通知
        } else {
            throw new YyghException(result.getString("message"), ResultCodeEnum.FAIL.getCode());
        }
        return orderInfo.getId();
    }
}

7. 预约成功后处理逻辑

预约成功后我们要更新预约数和短信提醒预约成功，为了提高下单的并发性，这部分逻辑我们就交给mq为我们完成，预约成功发送消息即可。

A、RabbitMQ 简介

以商品订单场景为例，如果商品服务和订单服务是两个不同的微服务，在下单的过程中订单服务需要调用商品服务进行扣库存操作。按照传统的方式，下单过程要等到调用完毕之后才能返回下单成功，如果网络产生波动等原因使得商品服务扣库存延迟或者失败，会带来较差的用户体验，如果在高并发的场景下，这样的处理显然是不合适的，那怎么进行优化呢？这就需要消息队列登场了。

消息队列提供一个异步通信机制，消息的发送者不必一直等待到消息被成功处理才返回，而是立即返回。消息中间件负责处理网络通信，如果网络连接不可用，消息被暂存于队列当中，当网络畅通的时候在将消息转发给相应的应用程序或者服务，当然前提是这些服务订阅了该队列。如果在商品服务和订单服务之间使用消息中间件，既可以提高并发量，又降低服务之间的耦合度。

RabbitMQ 就是这样一款消息队列。RabbitMQ 是一个开源的消息代理的队列服务器，用来通过普通协议在完全不同的应用之间共享数据。

B、典型应用场景

异步处理：

把消息放入消息中间件中，等到需要的时候再去处理。

流量削峰：

例如秒杀活动，在短时间内访问量急剧增加，使用消息队列，当消息队列满了就拒绝响应，跳转到错误页面，这样就可以使得系统不会因为超负载而崩溃。

日志处理

应用解耦

C、安装 RabbitMQ

docker pull rabbitmq:management
docker run -d -p 5672:5672 -p 15672:15672 --name rabbitmq rabbitmq:management

管理后台：http://IP:15672

① rabbit-util 模块封装

由于后续可能多个模块都会使用 mq，所以我们把它封装成一个模块，需要的地方直接引用即可

A、搭建 rabbit-util 模块

在 common 模块下搭建，搭建过程同：common-util

B、修改 pom.xml

<dependencies>
    <!--rabbitmq消息队列-->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-actuator</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-bus-amqp</artifactId>
    </dependency>
    <dependency>
        <groupId>com.alibaba</groupId>
        <artifactId>fastjson</artifactId>
    </dependency>
</dependencies>

C、封装 service 方法

@Service
public class RabbitService {
    @Autowired
    private RabbitTemplate rabbitTemplate;
    /**
     *  发送消息
     * @param exchange 交换机
     * @param routingKey 路由键
     * @param message 消息
     */
    public boolean sendMessage(String exchange, String routingKey, Object message) {
        rabbitTemplate.convertAndSend(exchange, routingKey, message);
        return true;
    }
}

D、配置 mq 消息转换器

@Configuration
public class MQConfig {
    @Bean
    public MessageConverter messageConverter(){
        return new Jackson2JsonMessageConverter();
    }
}

说明：默认是字符串转换器

② 封装短信接口

操作模块：service-msm

A、引入依赖

<dependency>
    <groupId>com.fancy.yygh</groupId>
    <artifactId>rabbit-util</artifactId>
    <version>0.0.1-SNAPSHOT</version>
</dependency>

B、添加配置

在 resources/application.properties 添加

#rabbitmq地址
spring.rabbitmq.host=192.168.44.165
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest

C、添加常量配置

在 rabbit-util 模块 com.fancy.yygh.common.constant.MqConst 类添加

public class MqConst {
    /**
     * 预约下单
     */
    public static final String EXCHANGE_DIRECT_ORDER = "exchange.direct.order";
    public static final String ROUTING_ORDER = "order";
    //队列
    public static final String QUEUE_ORDER  = "queue.order";
    /**
     * 短信
     */
    public static final String EXCHANGE_DIRECT_MSM = "exchange.direct.msm";
    public static final String ROUTING_MSM_ITEM = "msm.item";
    //队列
    public static final String QUEUE_MSM_ITEM  = "queue.msm.item";
}

D、在 model 模块封装短信实体

@Data
@ApiModel(description = "短信实体")
public class MsmVo {
    @ApiModelProperty(value = "phone")
    private String phone;
    @ApiModelProperty(value = "短信模板code")
    private String templateCode;
    @ApiModelProperty(value = "短信模板参数")
    private Map<String,Object> param;
}

说明：已统一引入

E、封装 service 接口

在 MsmService 类添加接口

boolean send(MsmVo msmVo);

在 MsmServiceImpl 类添加接口实现

@Override
public boolean send(MsmVo msmVo) {
    if(!StringUtils.isEmpty(msmVo.getPhone())) {
        String code = (String)msmVo.getParam().get("code");
        return this.send(msmVo.getPhone(),code);
    }
    return false;
}

F、封装 mq 监听器

@Component
public class SmsReceiver {
    @Autowired
    private MsmService msmService;
    @RabbitListener(bindings = @QueueBinding(
            value = @Queue(value = MqConst.QUEUE_MSM_ITEM, durable = "true"),
            exchange = @Exchange(value = MqConst.EXCHANGE_DIRECT_MSM),
            key = {MqConst.ROUTING_MSM_ITEM}
    ))
    public void send(MsmVo msmVo, Message message, Channel channel) {
        msmService.send(msmVo);
    }
}

③ 封装更新排班数量

操作模块：service-hosp

A、引入依赖

<!--rabbitmq消息队列-->
<dependency>
    <groupId>com.atguigu.yygh</groupId>
    <artifactId>rabbit-util</artifactId>
    <version>1.0</version>
</dependency>

B、添加配置

在 resources/application.properties 添加

#rabbitmq地址
spring.rabbitmq.host=192.168..38.130
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest

C、添加常量配置

在 rabbit-util 模块com.fancy.yygh.common.constant.MqConst类添加

/**
 * 预约下单
 */
public static final String EXCHANGE_DIRECT_ORDER = "exchange.direct.order";
public static final String ROUTING_ORDER = "order";
//队列
public static final String QUEUE_ORDER  = "queue.order";

D、在 model 模块封装更新排班实体

@Data
@ApiModel(description = "OrderMqVo")
public class OrderMqVo {
   @ApiModelProperty(value = "可预约数")
   private Integer reservedNumber;

   @ApiModelProperty(value = "剩余预约数")
   private Integer availableNumber;

   @ApiModelProperty(value = "排班id")
   private String scheduleId;

   @ApiModelProperty(value = "短信实体")
   private MsmVo msmVo;
}

说明：已统一引入，该对象放一个短信实体，预约下单成功后，我们发送一条消息，让 mq 来保证两个消息都发送成功

E、封装 service 接口

在 ScheduleService 类添加接口

/**
 * 修改排班
*/
void update(Schedule schedule);

在 ScheduleServiceImpl 类添加接口实现

@Override
public void update(Schedule schedule) {
    schedule.setUpdateTime(new Date());
    //主键一致就是更新
    scheduleRepository.save(schedule);
}

F、封装 mq 监听器

@Component
public class HospitalReceiver {

    @Autowired
    private ScheduleService scheduleService;

    @Autowired
    private RabbitService rabbitService;

    @RabbitListener(bindings = @QueueBinding(
            value = @Queue(value = MqConst.QUEUE_ORDER, durable = "true"),
            exchange = @Exchange(value = MqConst.EXCHANGE_DIRECT_ORDER),
            key = {MqConst.ROUTING_ORDER}
    ))
    public void receiver(OrderMqVo orderMqVo, Message message, Channel channel) throws IOException {
        //下单成功更新预约数
        Schedule schedule = scheduleService.getScheduleId(orderMqVo.getScheduleId());
        schedule.setReservedNumber(orderMqVo.getReservedNumber());
        schedule.setAvailableNumber(orderMqVo.getAvailableNumber());
        scheduleService.update(schedule);
        //发送短信
        MsmVo msmVo = orderMqVo.getMsmVo();
        if(null != msmVo) {
            rabbitService.sendMessage(MqConst.EXCHANGE_DIRECT_MSM, MqConst.ROUTING_MSM_ITEM, msmVo);
        }
    }
}

④ 调整下单接口

操作模块：service-order

A、引入依赖

<dependency>
    <groupId>com.fancy.yygh</groupId>
    <artifactId>rabbit-util</artifactId>
    <version>0.0.1-SNAPSHOT</version>
</dependency>

B、添加配置

在 resources/application.properties 添加

#rabbitmq地址
spring.rabbitmq.host=192.168.44.165
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest

C、修改下单接口

修改 OrderServiceImpl 类下单方法

@Autowired
private RabbitService rabbitService;

@Transactional(rollbackFor = Exception.class)
@Override
public Long saveOrder(String scheduleId, Long patientId) {
 		.......
        //排班可预约数
        Integer reservedNumber = jsonObject.getInteger("reservedNumber");
        //排班剩余预约数
        Integer availableNumber = jsonObject.getInteger("availableNumber");
        //发送mq信息更新号源和短信通知
        //发送mq信息更新号源
        OrderMqVo orderMqVo = new OrderMqVo();
        orderMqVo.setScheduleId(scheduleId);
        orderMqVo.setReservedNumber(reservedNumber);
        orderMqVo.setAvailableNumber(availableNumber);

        //短信提示
        MsmVo msmVo = new MsmVo();
        msmVo.setPhone(orderInfo.getPatientPhone());
        msmVo.setTemplateCode("SMS_194640721");
        String reserveDate = new DateTime(orderInfo.getReserveDate()).toString("yyyy-MM-dd") + (orderInfo.getReserveTime()==0 ? "上午": "下午");
        Map<String,Object> param = new HashMap<String,Object>(){{
            put("title", orderInfo.getHosname()+"|"+orderInfo.getDepname()+"|"+orderInfo.getTitle());
            put("amount", orderInfo.getAmount());
            put("reserveDate", reserveDate);
            put("name", orderInfo.getPatientName());
            put("quitTime", new DateTime(orderInfo.getQuitTime()).toString("yyyy-MM-dd HH:mm"));
        }};
        msmVo.setParam(param);

        orderMqVo.setMsmVo(msmVo);
        rabbitService.sendMessage(MqConst.EXCHANGE_DIRECT_ORDER, MqConst.ROUTING_ORDER, orderMqVo);
    } else {
        throw new YyghException(result.getString("message"), ResultCodeEnum.FAIL.getCode());
    }
    return orderInfo.getId();
}

三、订单管理

1. 订单列表

A、api 接口

① 添加 service 接口及实现类

在 OrderInfoService 类添加接口

/**
 * 分页列表
*/
IPage<OrderInfo> selectPage(Page<OrderInfo> pageParam, OrderQueryVo orderQueryVo);

在 OrderInfoServiceImpl 类添加接口实现

//订单列表（条件查询带分页）
@Override
public IPage<OrderInfo> selectPage(Page<OrderInfo> pageParam, OrderQueryVo orderQueryVo) {
    //orderQueryVo获取条件值
    String name = orderQueryVo.getKeyword(); //医院名称
    Long patientId = orderQueryVo.getPatientId(); //就诊人名称
    String orderStatus = orderQueryVo.getOrderStatus(); //订单状态
    String reserveDate = orderQueryVo.getReserveDate();//安排时间
    String createTimeBegin = orderQueryVo.getCreateTimeBegin();
    String createTimeEnd = orderQueryVo.getCreateTimeEnd();
    //对条件值进行非空判断
    QueryWrapper<OrderInfo> wrapper = new QueryWrapper<>();
    if(!StringUtils.isEmpty(name)) {
        wrapper.like("hosname",name);
    }
    if(!StringUtils.isEmpty(patientId)) {
        wrapper.eq("patient_id",patientId);
    }
    if(!StringUtils.isEmpty(orderStatus)) {
        wrapper.eq("order_status",orderStatus);
    }
    if(!StringUtils.isEmpty(reserveDate)) {
        wrapper.ge("reserve_date",reserveDate);
    }
    if(!StringUtils.isEmpty(createTimeBegin)) {
        wrapper.ge("create_time",createTimeBegin);
    }
    if(!StringUtils.isEmpty(createTimeEnd)) {
        wrapper.le("create_time",createTimeEnd);
    }
    //调用mapper的方法
    IPage<OrderInfo> pages = baseMapper.selectPage(pageParam, wrapper);
    //编号变成对应值封装
    pages.getRecords().stream().forEach(item -> {
        this.packOrderInfo(item);
    });
    return pages;
}
private OrderInfo packOrderInfo(OrderInfo orderInfo) {
    orderInfo.getParam().put("orderStatusString", OrderStatusEnum.getStatusNameByStatus(orderInfo.getOrderStatus()));
    return orderInfo;
}

② 添加 controller

在 OrderApiController 类添加方法

//订单列表（条件查询带分页）
@GetMapping("auth/{page}/{limit}")
public Result list(@PathVariable Long page,
                   @PathVariable Long limit,
                   OrderQueryVo orderQueryVo, HttpServletRequest request) {
    //设置当前用户id
    orderQueryVo.setUserId(AuthContextHolder.getUserId(request));
    Page<OrderInfo> pageParam = new Page<>(page,limit);
    IPage<OrderInfo> pageModel =
            orderService.selectPage(pageParam,orderQueryVo);
    return Result.ok(pageModel);
}

@ApiOperation(value = "获取订单状态")
@GetMapping("auth/getStatusList")
public Result getStatusList() {
    return Result.ok(OrderStatusEnum.getStatusList());
}

说明：订单状态我们是封装到枚举中的，页面搜索需要一个下拉列表展示，所以我们通过接口返回页面

B、前端

① 封装 api 请求
在 /api/orderInfo.js 添加方法

//订单列表
getPageList(page, limit, searchObj) {
    return request({
        url: `${api_name}/auth/${page}/${limit}`,
        method: `get`,
        params: searchObj
    })
},
//订单状态
getStatusList() {
    return request({
        url: `${api_name}/auth/getStatusList`,
        method: 'get'
    })
},

② 页面展示

创建 /pages/order/index.vue 组件

<template>
  <!-- header -->
  <div class="nav-container page-component">
    <!--左侧导航 #start -->
    <div class="nav left-nav">
      <div class="nav-item ">

      <div class="nav-item ">
        <span class="v-link clickable dark"> 修改账号信息 </span>
      </div>
      <div class="nav-item ">
        <span class="v-link clickable dark"> 意见反馈 </span>

2. 订单详情

A、api 接口

① 添加 service 接口及实现类

在 OrderInfoService 类添加接口

/**
 * 获取订单详情
*/
OrderInfo getOrderInfo(Long id);

在 OrderInfoServiceImpl 类添加接口实现

//根据订单id查询订单详情
@Override
public OrderInfo getOrder(String orderId) {
    OrderInfo orderInfo = baseMapper.selectById(orderId);
    return this.packOrderInfo②(orderInfo);
}

② 添加 controller

在 OrderApiController 类添加方法

//根据订单id查询订单详情
@GetMapping("auth/getOrders/{orderId}")
public Result getOrders(@PathVariable String orderId) {
    OrderInfo orderInfo = orderService.getOrder(orderId);
    return Result.ok(orderInfo);
}

B、前端

① 封装 api 请求

在 /api/order/orderInfo.js 添加方法

//订单详情
getOrders(orderId) {
    return request({
        url: `${api_name}/auth/getOrders/${orderId}`,
        method: `get`
    })
},

② 页面展示

三、平台订单管理

1. 订单列表

A、api 接口

① 添加 controller 方法

添加 com.fancy.yygh.order.controller.OrderController 类

@Api(tags = "订单接口")
@RestController
@RequestMapping("/admin/order/orderInfo")
public class OrderController {

    @Autowired
    private OrderService orderService;

    @ApiOperation(value = "获取分页列表")
    @GetMapping("{page}/{limit}")
    public Result index(
            @ApiParam(name = "page", value = "当前页码", required = true)
            @PathVariable Long page,
            @ApiParam(name = "limit", value = "每页记录数", required = true)
            @PathVariable Long limit,
            @ApiParam(name = "orderCountQueryVo", value = "查询对象", required = false) OrderQueryVo orderQueryVo) {
        Page<OrderInfo> pageParam = new Page<>(page, limit);
        IPage<OrderInfo> pageModel = orderService.selectPage(pageParam, orderQueryVo);
        return Result.ok(pageModel);
    }

    @ApiOperation(value = "获取订单状态")
    @GetMapping("getStatusList")
    public Result getStatusList() {
        return Result.ok(OrderStatusEnum.getStatusList());
    }
}

B、前端

① 添加路由
在 src/router/index.js 文件添加路由

{
  path: '/order',
  component: Layout,
  redirect: '/order/orderInfo/list',
  name: 'BasesInfo',
  meta: { title: '订单管理', icon: 'table' },
  alwaysShow: true,
  children: [
      {
        path: 'orderInfo/list',
        name: '订单列表',
        component: () =>import('@/views/order/orderInfo/list'),
        meta: { title: '订单列表' }
      }
    ]
}

② 封装 api 请求

添加 /api/order/orderInfo.js 文件

import request from '@/utils/request'
const api_name = '/admin/order/orderInfo'
export default {
  getPageList(page, limit, searchObj) {
    return request({
      url: `${api_name}/${page}/${limit}`,
      method: 'get',
      params: searchObj
    })
  },
  getStatusList() {
    return request({
      url: `${api_name}/getStatusList`,
      method: 'get'
    })
  }
}

③ 添加组件

创建 /views/order/orderInfo/list.vue 组件

<template>
  <div class="app-container">
    <el-form :inline="true" class="demo-form-inline">
      <el-form-item>
        <el-input v-model="searchObj.hosname" placeholder="医院名称"/>
      </el-form-item>
      <el-form-item>
        <el-input v-model="searchObj.outTradeNo" placeholder="订单号"/>
      </el-form-item>
      <el-form-item>
        <el-input v-model="searchObj.patientName" placeholder="就诊人名称"/>
      </el-form-item>
      <el-form-item>
        <el-date-picker
          v-model="searchObj.createTimeBegin"
          type="date"
          placeholder="选择开始日期"
          value-format="yyyy-MM-dd" />
      </el-form-item>
      <el-form-item>
        <el-date-picker
          v-model="searchObj.createTimeEnd"
          type="date"
          placeholder="选择截止日期"
          value-format="yyyy-MM-dd" />
      </el-form-item>
      <el-form-item>
        <el-date-picker
          v-model="searchObj.reserveDate"
          type="date"
          placeholder="就诊日期"
          value-format="yyyy-MM-dd" />
      </el-form-item>
      <el-form-item>
        <el-select v-model="searchObj.orderStatus" placeholder="订单状态" class="v-select patient-select">
          <el-option
            v-for="item in statusList"
            :key="item.status"
            :label="item.comment"
            :value="item.status">
          </el-option>
        </el-select>
      </el-form-item>
      <el-button type="primary" icon="el-icon-search" @click="fetchData()">查询</el-button>

      border
      fit
      highlight-current-row>
      <el-table-column
        label="序号"
        width="60"
        align="center">
        <template slot-scope="scope">

      :page-size="limit"
      :page-sizes="[5, 10, 20, 30, 40, 50, 100]"
      style="padding: 30px 0; text-align: center;"
      layout="sizes, prev, pager, next, jumper, ->, total, slot"
      @current-change="fetchData"
      @size-change="changeSize"
    />
  </div>
</template>
<script>
import orderInfoApi from '@/api/order/orderInfo'

export default {
  data() {
    return {
      listLoading: true, // 数据是否正在加载
      list: null, // banner列表
      total: 0, // 数据库中的总记录数
      page: 1, // 默认页码
      limit: 10, // 每页记录数
      searchObj: {} // 查询表单对象
    }
  },
  // 生命周期函数：内存准备完毕，页面尚未渲染
  created() {
    this.fetchData()
    this.getStatusList()
  },
  methods: {
    // 当页码发生改变的时候
    changeSize(size) {
      console.log(size)
      this.limit = size
      this.fetchData(1)
    },
    // 加载banner列表数据
    fetchData(page = 1) {
      console.log('翻页。。。' + page)
      // 异步获取远程数据（ajax）
      this.page = page
      orderInfoApi.getPageList(this.page, this.limit, this.searchObj).then(
        response => {
          debugger
          this.list = response.data.records
          this.total = response.data.total
          // 数据加载并绑定成功
          this.listLoading = false
        }
      )
    },
    getStatusList() {
      orderInfoApi.getStatusList().then(response => {
        this.statusList = response.data
      })
    },
    // 重置查询表单
    resetData() {
      console.log('重置查询表单')
      this.searchObj = {}
      this.fetchData()
    }
  }
}
</script>

2. 订单详情

A、api 接口

① 添加 service 接口及实现类

在 OrderInfoService 类添加接口

/**
 * 订单详情
 * @param orderId
* @return
*/
Map<String,Object> show(Long orderId);

在 OrderInfoServiceImpl 类添加接口实现

@Override
public Map<String, Object> show(Long orderId) {
   Map<String, Object> map = new HashMap<>();
   OrderInfo orderInfo = this.packOrderInfo(this.getById(orderId));
   map.put("orderInfo", orderInfo);
   Patient patient =  patientFeignClient.getPatient(orderInfo.getPatientId());
   map.put("patient", patient);
   return map;
}

② 添加 controller

在 OrderController 类添加方法

@ApiOperation(value = "获取订单")
@GetMapping("show/{id}")
public Result get(
@ApiParam(name = "orderId", value = "订单id", required = true)
@PathVariable Long id) {
   return Result.ok(orderService.show(id));
}

B、前端

① 添加路由
在 src/router/index.js 文件添加路由

{
  path: '/order',
  component: Layout,
  redirect: '/order/orderInfo/list',
  name: 'BasesInfo',
  meta: { title: '订单管理', icon: 'table' },
  alwaysShow: true,
  children: [
      {
        path: 'orderInfo/list',
        name: '订单列表',
        component: () =>import('@/views/order/orderInfo/list'),
        meta: { title: '订单列表' }
      },
      {
        path: 'orderInfo/show/:id',
        name: '查看',
              component: () =>import('@/views/order/orderInfo/show'),
        meta: { title: '查看', noCache: true },
        hidden: true
      }
    ]
}

② 封装 api 请求
在/api/order/orderInfo.js文件添加方法

getById(id) {
  return request({
    url: `${api_name}/show/${id}`,
    method: 'get'
  })
}

③ 修改列表组件

修改 /views/order/orderInfo/list.vue 组件

<el-table-column label="操作"width="100"align="center">
	<template slot-scope="scope">
	    <router-link :to="'/order/orderInfo/show/'+scope.row.id">
	      <el-button type="primary" size="mini" icon="el-icon-edit">查看</el-button>
	    </router-link>
	</template>
</el-table-column>

④ 添加组件

创建 /views/order/orderInfo/show.vue 组件

<template>
  <div class="app-container">
    <h4>订单信息</h4>
