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 {@Autowiredprivate GraphInfoService graphInfoService;@Autowiredprivate ApartmentFacilityService apartmentFacilityService;@Autowiredprivate ApartmentLabelService apartmentLabelService;@Autowiredprivate ApartmentFeeValueService apartmentFeeValueService;/*** 保存或更新公寓信息** @param apartmentSubmitVo*/@Override@Transactionalpublic 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_countfrom (select id,name,introduction,district_id,district_name,city_id,city_name,province_id,province_name,address_detail,latitude,longitude,phone,is_releasefrom 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>) aileft join(select apartment_id,count(*) cntfrom room_infowhere is_deleted = 0and is_release = 1group by apartment_id) tcon ai.id = tc.apartment_idleft join(select apartment_id,count(*) cntfrom lease_agreementwhere is_deleted = 0and status in (2, 5)group by apartment_id) ccon 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

*/
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 mapperPUBLIC "-//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">selectfv.id,fv.name,fv.unit,fv.fee_key_id,fk.name as fee_key_namefrom fee_value fvjoin fee_key fk on fv.fee_key_id = fk.idwhere fv.is_deleted = 0 and fk.is_deleted = 0and 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();}@Overridepublic 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);
}
