一、就医提醒
我们通过定时任务,每天8点执行,提醒就诊
1、搭建定时任务模块
(1)添加依赖
<dependencies>
<dependency>
<groupId>com.donglin</groupId>
<artifactId>rabbit_util</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
</dependencies>
(2)添加配置文件
# 服务端口
server.port=8208
# 服务名
spring.application.name=service-task
# 环境设置:dev、test、prod
spring.profiles.active=dev
# nacos服务地址
spring.cloud.nacos.discovery.server-addr=127.0.0.1:8848
#rabbitmq地址
spring.rabbitmq.host=192.168.121.140
spring.rabbitmq.port=5672
spring.rabbitmq.username=admin
spring.rabbitmq.password=admin
(3)添加启动类
@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
@EnableDiscoveryClient
@ComponentScan(basePackages = "com.donglin")
public class ServiceTaskApplication {
public static void main(String[] args) {
SpringApplication.run(ServiceTaskApplication.class, args);
}
}
(4)添加常量配置
在rabbit-util模块MqConst类添加
//定时任务
public static final String EXCHANGE_DIRECT_TASK = "exchange.direct.task";
public static final String ROUTING_TASK_8 = "task.8";
//队列
public static final String QUEUE_TASK_8 = "queue.task.8";
(5)添加定时任务
cron表达式
@Component
@EnableScheduling
public class PatientRemindJob {
//Quartz:
//Quartz:cron表达式: 秒 分 时 dayofMonth Month dayOfWeek Year[最高到2099年]
//*:表示任意xxx
//?:表示无所谓
//-:连续的时间段
// /n:表示每隔多长时间
// ,:可以使用,隔开没有规律的时间
@Autowired
private RabbitService rabbitService;
@Scheduled(cron="*/30 * * * * *")
public void printTime(){
// System.out.println(new DateTime().toString("yyyy-MM-dd HH:mm:ss"));
System.out.println(new Date().toLocaleString());
rabbitService.sendMessage(MqConst.EXCHANGE_DIRECT_TASK,MqConst.ROUTING_TASK_8,"");
}
//在springboot定时任务使用:1.在类上加@EnableScheduling 2.在定时任务Job的方法上加@Scheduled并指定石英表达式
//cron表达式写法:七域表达式
}
2、添加就医提醒处理
操作模块service-order
(1)添加OrderInfoService接口和实现
/**
* 就诊提醒
*/
void patientTips();
//实现方法
@Override
public void patientTips() {
QueryWrapper<OrderInfo> queryWrapper = new QueryWrapper<>();
queryWrapper.eq("reserve_date",new DateTime().toString("yyyy-MM-dd"));
//这里应该加个条件,订单状态不为-1的订单,-1表示已退号
queryWrapper.ne("order_status",-1);
List<OrderInfo> orderInfoList = baseMapper.selectList(queryWrapper);
for(OrderInfo orderInfo : orderInfoList) {
//短信提示
SmsVo smsVo = new SmsVo();
smsVo.setPhone(orderInfo.getPatientPhone());
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("reserveDate", reserveDate);
put("name", orderInfo.getPatientName());
}};
smsVo.setParam(param);
rabbitService.sendMessage(MqConst.EXCHANGE_DIRECT_SMS, MqConst.ROUTING_SMS_ITEM, smsVo);
}
}
(2)添加mq监听
@Component
public class TaskListener {
@Autowired
private OrderInfoService orderService;
@RabbitListener(bindings = @QueueBinding(
value = @Queue(value = MqConst.QUEUE_TASK_8, durable = "true"),
exchange = @Exchange(value = MqConst.EXCHANGE_DIRECT_TASK),
key = {MqConst.ROUTING_TASK_8}
))
public void patientTips(Message message, Channel channel) throws IOException {
orderService.patientTips();
}
}
找到自己当天预约的
状态为-1为退款 不发短信
每隔30秒打印信息
测试成功
二、后台管理系统-预约统计功能
我们统计医院每天的预约情况,通过图表的形式展示,统计的数据都来自订单模块,因此我们在该模块封装好数据,在统计模块通过feign的形式获取数据。
我们为什么需要一个统计模块呢,因为在实际的生产环境中,有很多种各式统计,数据来源于各个服务模块,我们得有一个统计模块来专门管理
1、开发每天预约数据接口
操作模块:service_orders
(1)在OrderInfoMapper添加方法
public interface OrderMapper extends BaseMapper<OrderInfo> {
//统计每天平台预约数据
List<OrderCountVo> selectOrderCount(OrderCountQueryVo orderCountQueryVo);
}
(2)在OrderInfoMapper.xml添加方法
创建OrderInfoMapper.xml文件
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.donglin.yygh.order.mapper.OrderInfoMapper">
<select id="selectOrderCount" resultType="com.donglin.yygh.vo.order.OrderCountVo">
select reserve_date as reserveDate, count(reserve_date) as count
from order_info
<where>
<if test="hosname != null and hosname != ''">
and hosname like CONCAT('%',#{hosname},'%')
</if>
<if test="reserveDateBegin != null and reserveDateBegin != ''">
and reserve_date >= #{reserveDateBegin}
</if>
<if test="reserveDateEnd != null and reserveDateEnd != ''">
and reserve_date <= #{reserveDateEnd}
</if>
and is_deleted = 0
</where>
group by reserve_date
order by reserve_date
</select>
</mapper>
(3)添加配置
application.properties添加
mybatis-plus.mapper-locations=classpath:com/donglin/yygh/orders/mapper/xml/*.xml
service模块的pom.xml添加
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
<resources>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.yml</include>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>false</filtering>
</resource>
<resource>
<directory>src/main/resources</directory>
<includes> <include>**/*.yml</include>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>false</filtering>
</resource>
</resources>
</build>
(4)OrderService添加方法和实现
/**
* 订单统计
*/
Map<String, Object> getCountMap(OrderCountQueryVo orderCountQueryVo);
//实现方法
@Override
public Map<String, Object> getCountMap(OrderCountQueryVo orderCountQueryVo) {
Map<String, Object> map = new HashMap<>();
List<OrderCountVo> orderCountVoList
= baseMapper.selectOrderCount(orderCountQueryVo);
//日期列表
List<String> dateList
=orderCountVoList.stream().map(OrderCountVo::getReserveDate).collect(Collectors.toList());
//统计列表
List<Integer> countList
=orderCountVoList.stream().map(OrderCountVo::getCount).collect(Collectors.toList());
map.put("dateList", dateList);
map.put("countList", countList);
return map;
}
(5)在OrderInfoController添加方法
@ApiOperation(value = "获取订单统计数据")
@PostMapping("inner/getCountMap")
public Map<String, Object> getCountMap(@RequestBody OrderCountQueryVo orderCountQueryVo) {
return orderInfoService.getCountMap(orderCountQueryVo);
}
2、封装远程调用接口
(1)创建模块:service_order_client
(2)添加feign接口
@FeignClient(value = "service-orders")
@Repository
public interface OrderFeignClient {
/**
* 获取订单统计数据
*/
@PostMapping("/api/order/orderInfo/inner/getCountMap")
Map<String, Object> getCountMap(@RequestBody OrderCountQueryVo orderCountQueryVo);
}
3、搭建统计分析模块
(1)创建service_statistics模块
(2)引入依赖
<dependencies>
<dependency>
<groupId>com.donglin</groupId>
<artifactId>service_order_client</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
</dependencies>
(3)添加配置文件
# 服务端口
server.port=8209
# 服务名
spring.application.name=service-sta
# 环境设置:dev、test、prod
spring.profiles.active=dev
# nacos服务地址
spring.cloud.nacos.discovery.server-addr=127.0.0.1:8848
(4)添加启动类
@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
@EnableDiscoveryClient
@EnableFeignClients(basePackages = {"com.donglin"})
@ComponentScan(basePackages = {"com.donglin"})
public class ServiceStatisticsApplication {
public static void main(String[] args) {
SpringApplication.run(ServiceStatisticsApplication.class, args);
}
}
(5)添加controller方法
@Api(tags = "统计管理接口")
@RestController
@RequestMapping("/admin/statistics")
public class StatisticsController {
@Autowired
private OrderFeignClient orderFeignClient;
@ApiOperation(value = "获取订单统计数据")
@GetMapping("getCountMap")
public R getCountMap(@ApiParam(name = "orderCountQueryVo", value = "查询对象", required = false) OrderCountQueryVo orderCountQueryVo) {
Map<String, Object> map = orderFeignClient.getCountMap(orderCountQueryVo);
return R.ok().data(map);
}
}
service-gateway下的resource下的application.yml加上网关
- id: service-sta
uri: lb://service-sta
predicates:
- Path=/*/statistics/** # 路径匹配
4、整合统计功能前端
ECharts是百度的一个项目,后来百度把Echart捐给apache,用于图表展示,提供了常规的折线图、柱状图、散点图、饼图、K线图,用于统计的盒形图,用于地理数据可视化的地图、热力图、线图,用于关系数据可视化的关系图、treemap、旭日图,多维数据可视化的平行坐标,还有用于 BI 的漏斗图,仪表盘,并且支持图与图之间的混搭。
官方网站:https://echarts.apache.org/zh/index.html
(1)项目中安装 echarts组件
npm install --save echarts@4.1.0
(2)添加路由
{
path: '/statistics',
component: Layout,
redirect: '/statistics/order/index',
name: 'BasesInfo',
meta: { title: '统计管理', icon: 'table' },
alwaysShow: true,
children: [
{
path: 'order/index',
name: '预约统计',
component: () =>import('@/views/yygh/sta/index'),
meta: { title: '预约统计' }
}
]
},
(3)封装api请求
sta.js
import request from '@/utils/request'
const api_name = '/admin/statistics'
export default {
getCountMap(searchObj) {
return request({
url: `${api_name}/getCountMap`,
method: 'get',
params: searchObj
})
}
}
(4)添加组件
创建/views/yygh/sta/index.vue组件
<template>
<div class="app-container">
<!--表单-->
<el-form :inline="true" class="demo-form-inline">
<el-form-item>
<el-input v-model="searchObj.hosname" placeholder="点击输入医院名称"/>
</el-form-item>
<el-form-item>
<el-date-picker
v-model="searchObj.reserveDateBegin"
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.reserveDateEnd"
type="date"
placeholder="选择截止日期"
value-format="yyyy-MM-dd"/>
</el-form-item>
<el-button
:disabled="btnDisabled"
type="primary"
icon="el-icon-search"
@click="showChart()">查询</el-button>
</el-form>
<div class="chart-container">
<div id="chart" ref="chart"
class="chart" style="height:500px;width:100%"/>
</div>
</div>
</template>
<script>
import echarts from 'echarts'
import statisticsApi from '@/api/sta'
export default {
data() {
return {
searchObj: {
hosname: '',
reserveDateBegin: '',
reserveDateEnd: ''
},
btnDisabled: false,
chart: null,
title: '',
xData: [], // x轴数据
yData: [] // y轴数据
}
},
methods: {
// 初始化图表数据
showChart() {
statisticsApi.getCountMap(this.searchObj).then(response => {
this.yData = response.data.countList
this.xData = response.data.dateList
this.setChartData()
})
},
setChartData() {
// 基于准备好的dom,初始化echarts实例
var myChart = echarts.init(document.getElementById('chart'))
// 指定图表的配置项和数据
var option = {
title: {
text: this.title + '挂号量统计'
},
tooltip: {},
legend: {
data: [this.title]
},
xAxis: {
data: this.xData
},
yAxis: {
minInterval: 1
},
series: [{
name: this.title,
type: 'line',
data: this.yData
}]
}
// 使用刚指定的配置项和数据显示图表。
myChart.setOption(option)
},
}
}
</script>
