1、业务介绍
公寓管理共有六个接口，分别是
- 保存或更新公寓信息
- 根据条件分页查询详细信息
- 根据ID获取公寓详情信息
- 根据ID删除公寓信息
- 根据ID修改公寓发布状态
- 根据区县ID查询公寓信息列表
2、逻辑模型介绍
3、接口开发
3.1、保存或更新公寓信息
查看接口
进行开发
查看web-admin模块中的com.atguigu.lease.web.admin.vo.apartment.ApartmentSubmitVo类，内容如下：
@Schema(description = "公寓信息")
@Data
public class ApartmentSubmitVo extends ApartmentInfo {
@Schema(description="公寓配套id")
private List<Long> facilityInfoIds;
@Schema(description="公寓标签id")
private List<Long> labelIds;
@Schema(description="公寓杂费值id")
private List<Long> feeValueIds;
@Schema(description="公寓图片id")
private List<GraphVo> graphVoList;
}
编写Controller层逻辑
@Operation(summary = "保存或更新公寓信息")
@PostMapping("saveOrUpdate")
public Result saveOrUpdate(@RequestBody ApartmentSubmitVo apartmentSubmitVo) {
service.saveOrUpdateApartment(apartmentSubmitVo);
return Result.ok();
}
编写Service层逻辑
-
在
ApartmentInfoService中增加如下内容void saveOrUpdateApartment(ApartmentSubmitVo apartmentSubmitVo); -
在
ApartmentInfoServiceImpl中增加如下内容/** * @author liubo * @description 针对表【apartment_info(公寓信息表)】的数据库操作Service实现 * @createDate 2023-07-24 15:48:00 */ @Service public class ApartmentInfoServiceImpl extends ServiceImpl<ApartmentInfoMapper, ApartmentInfo> implements ApartmentInfoService { @Autowired private GraphInfoService graphInfoService; @Autowired private ApartmentFacilityService apartmentFacilityService; @Autowired private ApartmentLabelService apartmentLabelService; @Autowired private ApartmentFeeValueService apartmentFeeValueService; /** * 保存或更新公寓信息 * * @param apartmentSubmitVo */ @Override @Transactional public void apartmentSaveOrUpdate(ApartmentSubmitVo apartmentSubmitVo) { //判断是新增方法还是修改方法 boolean isUpdate = apartmentSubmitVo.getId() != null; super.saveOrUpdate(apartmentSubmitVo); if (isUpdate){ //进行删除，先删除后再添加 //删除图片 LambdaQueryWrapper<GraphInfo> graphInfoQueryWrapper = new LambdaQueryWrapper<>(); graphInfoQueryWrapper.eq(GraphInfo::getItemType, ItemType.APARTMENT); graphInfoQueryWrapper.eq(GraphInfo::getItemId,apartmentSubmitVo.getId()); graphInfoService.remove(graphInfoQueryWrapper); //删除配套列表 LambdaQueryWrapper<ApartmentFacility> apartmentFacilityQueryWrapper = new LambdaQueryWrapper<>(); apartmentFacilityQueryWrapper.eq(ApartmentFacility::getApartmentId,apartmentSubmitVo.getId()); apartmentFacilityService.remove(apartmentFacilityQueryWrapper); //删除标签 LambdaQueryWrapper<ApartmentLabel> apartmentLabelQueryWrapper = new LambdaQueryWrapper<>(); apartmentLabelQueryWrapper.eq(ApartmentLabel::getApartmentId,apartmentSubmitVo.getId()); apartmentLabelService.remove(apartmentLabelQueryWrapper); //删除杂费 LambdaQueryWrapper<ApartmentFeeValue> apartmentFeeValueQueryWrapper = new LambdaQueryWrapper<>(); apartmentFeeValueQueryWrapper.eq(ApartmentFeeValue::getApartmentId,apartmentSubmitVo.getId()); apartmentFeeValueService.remove(apartmentFeeValueQueryWrapper); } //插入图片 List<GraphVo> graphVoList = apartmentSubmitVo.getGraphVoList(); if (!CollectionUtils.isEmpty(graphVoList)){ List<GraphInfo> graphInfoList = new ArrayList<>(); //循环添加 for (GraphVo graphVo : graphVoList) { GraphInfo graphInfo = GraphInfo.builder() .name(graphVo.getName()) .url(graphVo.getUrl()) .itemId(apartmentSubmitVo.getId()) .itemType(ItemType.APARTMENT) .build(); graphInfoList.add(graphInfo); } graphInfoService.saveBatch(graphInfoList); } } }
3.2、根据条件分页查询详细信息
查看接口
进行开发
查看请求和响应的数据结构
-
请求数据结构
-
current和size为分页相关参数，分别表示当前所处页面和每个页面的记录数。 -
ApartmentQueryVo为公寓的查询条件，详细结构如下：
-
@Schema(description = "公寓信息")
@Data
public class ApartmentDetailVo extends ApartmentInfo {
@Schema(description = "图片列表")
private List<GraphVo> graphVoList;
@Schema(description = "标签列表")
private List<LabelInfo> labelInfoList;
@Schema(description = "配套列表")
private List<FacilityInfo> facilityInfoList;
@Schema(description = "杂费列表")
private List<FeeValueVo> feeValueVoList;
}
响应数据结构
单个公寓信息记录可查看com.atguigu.lease.web.admin.vo.apartment.ApartmentItemVo，内容如下：
@Data
@Schema(description = "后台管理系统公寓列表实体")
public class ApartmentItemVo extends ApartmentInfo {
@Schema(description = "房间总数")
private Long totalRoomCount;
@Schema(description = "空闲房间数")
private Long freeRoomCount;
}
配置Mybatis-Plus分页插件
在common模块中的com.atguigu.lease.common.mybatisplus.MybatisPlusConfiguration中增加如下内容：
@Bean
public MybatisPlusInterceptor mybatisPlusInterceptor() {
MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL));
return interceptor;
}
接口实现
-
编写Controller层逻辑
在
ApartmentController中增加如下内容：
@Operation(summary = "根据条件分页查询公寓列表")
@GetMapping("pageItem")
public Result<IPage<ApartmentItemVo>> pageItem(@RequestParam long current, @RequestParam long size, ApartmentQueryVo queryVo) {
IPage<ApartmentItemVo> page = new Page<>(current, size);
IPage<ApartmentItemVo> list = service.pageApartmentItemByQuery(page, queryVo);
return Result.ok(list);
}
编写Service层逻辑
- 在
ApartmentInfoService中增加如下内容
IPage<ApartmentItemVo> pageApartmentItemByQuery(IPage<ApartmentItemVo> page, ApartmentQueryVo queryVo);
在ApartmentInfoServiceImpl中增加如下内容
@Autowired
private ApartmentInfoMapper apartmentInfoMapper;
/**
* 分页查询
* @param page
* @param queryVo
* @return
*/
@Override
public IPage<ApartmentItemVo> pageItem(IPage<ApartmentItemVo> page, ApartmentQueryVo queryVo) {
return apartmentInfoMapper.pageItem(page,queryVo);
}
编写Mapper层逻辑
在ApartmentInfoMapper中增加如下内容
IPage<ApartmentItemVo> pageApartmentItemByQuery(IPage<ApartmentItemVo> page, ApartmentQueryVo queryVo);
在ApartmentInfoMapper.xml中增加如下内容
<select id="pageItem" resultType="com.atguigu.lease.web.admin.vo.apartment.ApartmentItemVo">
select ai.id,
ai.name,
ai.introduction,
ai.district_id,
ai.district_name,
ai.city_id,
ai.city_name,
ai.province_id,
ai.province_name,
ai.address_detail,
ai.latitude,
ai.longitude,
ai.phone,
ai.is_release,
ifnull(tc.cnt,0) total_room_count,
ifnull(tc.cnt,0) - ifnull(cc.cnt,0) free_room_count
from (select id,
name,
introduction,
district_id,
district_name,
city_id,
city_name,
province_id,
province_name,
address_detail,
latitude,
longitude,
phone,
is_release
from apartment_info
<where>
is_deleted=0
<if test="queryVo.provinceId != null">
and province_id=#{queryVo.provinceId}
</if>
<if test="queryVo.cityId != null">
and city_id=#{queryVo.cityId}
</if>
<if test="queryVo.districtId != null">
and district_id=#{queryVo.districtId}
</if>
</where>
) ai
left join
(select apartment_id,
count(*) cnt
from room_info
where is_deleted = 0
and is_release = 1
group by apartment_id) tc
on ai.id = tc.apartment_id
left join
(select apartment_id,
count(*) cnt
from lease_agreement
where is_deleted = 0
and status in (2, 5)
group by apartment_id) cc
on ai.id = cc.apartment_id
</select>
注意：
默认情况下Knife4j为该接口生成的接口文档如下图所示，其中的queryVo参数不方便调试
可在application.yml文件中增加如下配置，将queryVo做打平处理
springdoc:
default-flat-param-object: true
将spring.default-flat-param-object参数设置为true后，效果如下。
3.3、根据ID获取公寓详细信息
查看接口
查看响应数据结构
查看web-admin下的com.atguigu.lease.web.admin.vo.apartment.ApartmentDetailVo，内容如下
@Schema(description = "公寓信息")
@Data

private List<GraphVo> graphVoList;
@Schema(description = "标签列表")
private List<LabelInfo> labelInfoList;
@Schema(description = "配套列表")
private List<FacilityInfo> facilityInfoList;

*/
@Override
public ApartmentDetailVo getDetailById(Long id) {
//1、根据id或获取公寓信息
ApartmentInfo apartmentInfo = this.getById(id);
if (apartmentInfo == null){
return null;
}
//2、获取图片列表
List<GraphVo> graphVoList = graphInfoMapper.getByIdGraphList(id,ItemType.APARTMENT);
//3、获取标签列表
List<LabelInfo> labelInfoList = labelInfoMapper.selectListByApartmentId(id);
//4、查询配套列表
List<FacilityInfo> facilityInfoList = facilityInfoMapper.selectListByApartmentId(id);
//5、查询杂费信息列表
List<FeeValueVo> feeValueVoList = feeValueMapper.selectListByApartmentId(id);
ApartmentDetailVo apartmentDetailVo = new ApartmentDetailVo();
//复制属性
BeanUtils.copyProperties(apartmentInfo,apartmentDetailVo);
//增加属性
apartmentDetailVo.setGraphVoList(graphVoList);
apartmentDetailVo.setLabelInfoList(labelInfoList);
apartmentDetailVo.setFacilityInfoList(facilityInfoList);
apartmentDetailVo.setFeeValueVoList(feeValueVoList);
return apartmentDetailVo;
}
编写Mapper层逻辑
编写公寓图片查询逻辑,在GraphInfoMapper中增加如下内容
/**
* @author liubo
* @description 针对表【graph_info(图片信息表)】的数据库操作Mapper
* @createDate 2023-07-24 15:48:00
* @Entity com.atguigu.lease.model.GraphInfo
*/
public interface GraphInfoMapper extends BaseMapper<GraphInfo> {
@Select("select name,url from graph_info where is_deleted=0 and item_id = #{id} and item_id = #{itemType}")
List<GraphVo> getByIdGraphList(Long id,ItemType itemType);
}
编写公寓标签查询逻辑
在LabelInfoMapper中增加如下内容
/**
* @author liubo
* @description 针对表【label_info(标签信息表)】的数据库操作Mapper
* @createDate 2023-07-24 15:48:00
* @Entity com.atguigu.lease.model.LabelInfo
*/
public interface LabelInfoMapper extends BaseMapper<LabelInfo> {
/**
* 获取标签列表
* @param id
* @return
*/
@Select("select id, type, name from label_info where label_info.is_deleted = 0 and id in " +
"(select apartment_label.label_id from apartment_label where apartment_label.is_deleted = 0 and apartment_id = #{id})")
List<LabelInfo> selectListByApartmentId(Long id);
}
编写公寓配套查询逻辑
在FacilityInfoMapper中增加如下内容

*/
public interface FacilityInfoMapper extends BaseMapper<FacilityInfo> {
/**
* 根据id查询配套信息
* @param id
* @return
*/
@Select("select id,type,name,icon from facility_info where " +
"is_deleted=0 and id in " +
"(select facility_id from apartment_facility where is_deleted = 0 and apartment_id = #{id})")
List<FacilityInfo> selectListByApartmentId(Long id);
}List<FacilityInfo> selectListByApartmentId(Long id);
编写公寓杂费查询逻辑
在FeeValueMapper中增加如下内容
/**
* @author liubo
* @description 针对表【fee_value(杂项费用值表)】的数据库操作Mapper
* @createDate 2023-07-24 15:48:00
* @Entity com.atguigu.lease.model.FeeValue
*/
public interface FeeValueMapper extends BaseMapper<FeeValue> {
List<FeeValueVo> selectListByApartmentId(Long id);
}
在FeeValueMapper.xml中增加如下内容
<?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.atguigu.lease.web.admin.mapper.FeeValueMapper">
<select id="selectListByApartmentId" resultType="com.atguigu.lease.web.admin.vo.fee.FeeValueVo">
select
fv.id,
fv.name,
fv.unit,
fv.fee_key_id,
fk.name as fee_key_name
from fee_value fv
join fee_key fk on fv.fee_key_id = fk.id
where fv.is_deleted = 0 and fk.is_deleted = 0
and fv.id in
(select fee_value_id from apartment_fee_value where is_deleted = 0 and apartment_id = #{id})
</select>
</mapper>
3.4、 根据ID删除公寓信息
查看接口
编写Controller层逻辑
在ApartmentController中增加如下内容
@Operation(summary = "根据id删除公寓信息")
@DeleteMapping("removeById")
public Result removeById(@RequestParam Long id) {
apartmentInfoService.removeApartmentById(id);
return Result.ok();
}
编写Service层逻辑
在ApartmentInfoService中增加如下内容
/**
* 根据id删除公寓信息
* @param id
*/
void removeApartmentById(Long id);
在ApartmentInfoServiceImpl中增加如下内容
@Autowired
private RoomInfoMapper roomInfoMapper;
/**
* 根据id删除公寓信息
*
* @param id
*/
@Override
@Transactional
public void removeApartmentById(Long id) {
//查询公寓内是否有房间
LambdaQueryWrapper<RoomInfo> queryWrapper = new LambdaQueryWrapper<>();
queryWrapper.eq(RoomInfo::getApartmentId,id);
Long count = roomInfoMapper.selectCount(queryWrapper);
if (count > 0){
throw new LeaseException(ResultCodeEnum.ADMIN_APARMIN_APARTMENT_DELETE_ERROR);
}
//删除公寓
super.removeById(id);
//删除图片
LambdaQueryWrapper<GraphInfo> graphInfoQueryWrapper = new LambdaQueryWrapper<>();
graphInfoQueryWrapper.eq(GraphInfo::getItemType, ItemType.APARTMENT);
graphInfoQueryWrapper.eq(GraphInfo::getItemId,id);
graphInfoService.remove(graphInfoQueryWrapper);
//删除配套列表
LambdaQueryWrapper<ApartmentFacility> apartmentFacilityQueryWrapper = new LambdaQueryWrapper<>();
apartmentFacilityQueryWrapper.eq(ApartmentFacility::getApartmentId,id);
apartmentFacilityService.remove(apartmentFacilityQueryWrapper);
//删除标签
LambdaQueryWrapper<ApartmentLabel> apartmentLabelQueryWrapper = new LambdaQueryWrapper<>();
apartmentLabelQueryWrapper.eq(ApartmentLabel::getApartmentId,id);
apartmentLabelService.remove(apartmentLabelQueryWrapper);
//删除杂费
LambdaQueryWrapper<ApartmentFeeValue> apartmentFeeValueQueryWrapper = new LambdaQueryWrapper<>();
apartmentFeeValueQueryWrapper.eq(ApartmentFeeValue::getApartmentId,id);
apartmentFeeValueService.remove(apartmentFeeValueQueryWrapper);
}
知识点：
由于公寓下会包含房间信息，因此在删除公寓时最好先判断一下该公寓下是否存在房间信息，若存在，则提醒用户先删除房间信息后再删除公寓信息，判断逻辑如下
LambdaQueryWrapper<RoomInfo> roomQueryWrapper = new LambdaQueryWrapper<>();
roomQueryWrapper.eq(RoomInfo::getApartmentId, id);
Long count = roomInfoMapper.selectCount(roomQueryWrapper);
if (count > 0) {
//直接为前端返回如下响应：先删除房间信息再删除公寓信息
}
想要直接为前端返回响应，可利用前边配置的全局异常处理功能（此处直接抛出异常，全局异常处理器捕获到异常后，便会直接为前端返回响应结果）。
为灵活设置响应信息，可自定义异常类，如下
在common模块创建com.atguigu.lease.common.exception.LeaseException类，内容如下：
@Data
public class LeaseException extends RuntimeException {
//异常状态码
private Integer code;
/**
* 通过状态码和错误消息创建异常对象
* @param message
* @param code
*/
public LeaseException(String message, Integer code) {
super(message);
this.code = code;
}
/**
* 根据响应结果枚举对象创建异常对象
* @param resultCodeEnum
*/
public LeaseException(ResultCodeEnum resultCodeEnum) {
super(resultCodeEnum.getMessage());
this.code = resultCodeEnum.getCode();
}
@Override
public String toString() {
return "LeaseException{" +
"code=" + code +
", message=" + this.getMessage() +
'}';
}
}
在common模块的com.atguigu.lease.common.exception.GlobalExceptionHandler类中，增加自定义异常类的处理逻辑
@ExceptionHandler(LeaseException.class)
@ResponseBody
public Result error(LeaseException e){
e.printStackTrace();
return Result.fail(e.getCode(), e.getMessage());
}
为Result新增一个构造方法，如下
public static <T> Result<T> fail(Integer code, String message) {
Result<T> result = build(null);
result.setCode(code);
result.setMessage(message);
return result;
}
3.5、根据ID修改公寓发布状态
查看接口
进行开发
在ApartmentController中增加如下内容：
@Operation(summary = "根据id修改公寓发布状态")
@PostMapping("updateReleaseStatusById")
public Result updateReleaseStatusById(@RequestParam Long id, @RequestParam ReleaseStatus status) {
LambdaQueryWrapper<ApartmentInfo> apartmentInfoQueryWrapper = new LambdaQueryWrapper<>();
apartmentInfoQueryWrapper.eq(ApartmentInfo::getId,id);
apartmentInfoQueryWrapper.eq(ApartmentInfo::getIsRelease,status);
apartmentInfoService.update(apartmentInfoQueryWrapper);
return Result.ok();
}
3.6、根据区县ID查询公寓信息列表
查看接口
进行开发
在ApartmentController中增加如下内容：
@Operation(summary = "根据区县id查询公寓信息列表")
@GetMapping("listInfoByDistrictId")
public Result<List<ApartmentInfo>> listInfoByDistrictId(@RequestParam Long id) {
LambdaQueryWrapper<ApartmentInfo> apartmentInfoQueryWrapper = new LambdaQueryWrapper<>();
apartmentInfoQueryWrapper.eq(ApartmentInfo::getDistrictId,id);
List<ApartmentInfo> list = apartmentInfoService.list(apartmentInfoQueryWrapper);
return Result.ok(list);
}
