1、业务介绍
找房模块一共分为三部分
- 地区信息
- 查询省份列表
- 根据省份id查询城市列表
- 根据城市id查询区县列表
- 公寓信息
- 房间信息
- 根据条件分页查询房间列表
- 根据id查询房间详细信息
- 根据公寓id分页查询房间列表
2、接口开发
2.1、地区信息
对于找房模块，地区信息共需三个接口，分别是查询省份列表、根据省份ID查询城市列表、根据城市ID查询区县列表，具体实现如下
在RegionController中增加如下内容
@Tag(name = "地区信息")
@RestController
@RequestMapping("/app/region")
public class RegionController {
@Autowired
private ProvinceInfoService provinceInfoService;
@Autowired
private CityInfoService cityInfoService;
@Autowired
private DistrictInfoService districtInfoService;
@Operation(summary="查询省份信息列表")
@GetMapping("province/list")
public Result<List<ProvinceInfo>> listProvince(){
List<ProvinceInfo> list = provinceInfoService.list();
return Result.ok(list);
}
@Operation(summary="根据省份id查询城市信息列表")
@GetMapping("city/listByProvinceId")
public Result<List<CityInfo>> listCityInfoByProvinceId(@RequestParam Long id){
LambdaQueryWrapper<CityInfo> queryWrapper = new LambdaQueryWrapper<>();
queryWrapper.eq(CityInfo::getProvinceId,id);
List<CityInfo> list = cityInfoService.list(queryWrapper);
return Result.ok(list);
}
@GetMapping("district/listByCityId")
@Operation(summary="根据城市id查询区县信息")
public Result<List<DistrictInfo>> listDistrictInfoByCityId(@RequestParam Long id){
LambdaQueryWrapper<DistrictInfo> queryWrapper = new LambdaQueryWrapper<>();
queryWrapper.eq(DistrictInfo::getCityId,id);
List<DistrictInfo> list = districtInfoService.list(queryWrapper);
return Result.ok(list);
}
}
2.2、获取全部支付方式列表
对于找房模块，支付方式共需一个接口，即获取全部支付方式列表，具体实现如下
在PaymentTypeController中增加如下内容
@Tag(name = "支付方式接口")
@RestController
@RequestMapping("/app/payment")
public class PaymentTypeController {
@Autowired
private PaymentTypeService service;
@Operation(summary = "获取全部支付方式列表")
@GetMapping("list")
public Result<List<PaymentType>> list() {
List<PaymentType> list = service.list();
return Result.ok(list);
}
}
2.3、房间信息
房间信息共需三个接口，分别是根据条件分页查询房间列表、根据ID查询房间详细信息、根据公寓ID分页查询房间列表，下面逐一实现
首先在RoomController中注入RoomInfoService，如下
@Tag(name = "房间信息")
@RestController
@RequestMapping("/app/room")
public class RoomController {
@Autowired
RoomInfoService roomInfoService;
}
2.2.1. 根据条件分页查询房间列表
-
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。 -
RoomQueryVo为房间的查询条件，详细结构如下：@Data @Schema(description = "房间查询实体") public class RoomQueryVo { @Schema(description = "省份Id") private Long provinceId; @Schema(description = "城市Id") private Long cityId; @Schema(description = "区域Id") private Long districtId; @Schema(description = "最小租金") private BigDecimal minRent; @Schema(description = "最大租金") private BigDecimal maxRent; @Schema(description = "支付方式") private Long paymentTypeId; @Schema(description = "价格排序方式", allowableValues = {"desc", "asc"}) private String orderType; }
-
-
响应数据结构
单个房间信息记录可查看
com.atguigu.lease.web.app.vo.room.RoomItemVo，内容如下：@Schema(description = "APP房间列表实体") @Data public class RoomItemVo { @Schema(description = "房间id") private Long id; @Schema(description = "房间号") private String roomNumber; @Schema(description = "租金（元/月）") private BigDecimal rent; @Schema(description = "房间图片列表") private List<GraphVo> graphVoList; @Schema(description = "房间标签列表") private List<LabelInfo> labelInfoList; @Schema(description = "房间所属公寓信息") private ApartmentInfo apartmentInfo; }
-
-
编写Controller层逻辑
在
RoomController中增加如下内容@Operation(summary = "分页查询房间列表") @GetMapping("pageItem") public Result<IPage<RoomItemVo>> pageItem(@RequestParam long current, @RequestParam long size, RoomQueryVo queryVo) { Page<RoomItemVo> page = new Page<>(current, size); IPage<RoomItemVo> list = roomInfoService.pageRoomItemByQuery(page, queryVo); return Result.ok(list); } -
编写Service层逻辑
-
在
RoomInfoService中增加如下内容IPage<RoomItemVo> pageRoomItemByQuery(Page<RoomItemVo> page, RoomQueryVo queryVo); -
在
RoomInfoServiceImpl中增加如下内容@Override public IPage<RoomItemVo> pageRoomItemByQuery(Page<RoomItemVo> page, RoomQueryVo queryVo) { return roomInfoMapper.pageRoomItemByQuery(page, queryVo); }
-
-
编写Mapper层逻辑
-
在
RoomInfoMapper中增加如下内容IPage<RoomItemVo> pageRoomItemByQuery(Page<RoomItemVo> page, RoomQueryVo queryVo); -
在
RoomInfoMapper中增加如下内容<!-- result map --> <resultMap id="RoomItemVoMap" type="com.atguigu.lease.web.app.vo.room.RoomItemVo" autoMapping="true"> <id column="id" property="id"/> <!--映射公寓信息--> <association property="apartmentInfo" javaType="com.atguigu.lease.model.entity.ApartmentInfo" autoMapping="true"> <id column="id" property="id"/> </association> <!--映射图片列表--> <collection property="graphVoList" ofType="com.atguigu.lease.web.app.vo.graph.GraphVo" select="selectGraphVoListByRoomId" column="id"/> <!--映射标签列表--> <collection property="labelInfoList" ofType="com.atguigu.lease.model.entity.LabelInfo" select="selectLabelInfoListByRoomId" column="id"/> </resultMap> <!-- 根据条件查询房间列表 --> <select id="pageItem" resultMap="RoomItemVoMap"> select ri.id, ri.room_number, ri.rent, ai.id apartment_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 from room_info ri left join apartment_info ai on ri.apartment_id = ai.id and ai.is_deleted = 0 <where> ri.is_deleted = 0 and ri.is_release = 1 and ri.id not in( select room_id from lease_agreement where is_deleted = 0 and status in(2,5)) <if test="queryVo.provinceId != null"> and ai.province_id = #{queryVo.provinceId} </if> <if test="queryVo.cityId != null"> and ai.city_id = #{queryVo.cityId} </if> <if test="queryVo.districtId != null"> and ai.district_id = #{queryVo.districtId} </if> <if test="queryVo.minRent != null and queryVo.maxRent != null"> and (ri.rent >= #{queryVo.minRent} and ri.rent <= #{queryVo.maxRent}) </if> <if test="queryVo.paymentTypeId != null"> and ri.id in ( select room_id from room_payment_type where is_deleted = 0 and payment_type_id = #{queryVo.paymentTypeId} ) </if> </where> <if test="queryVo.orderType == 'desc' or queryVo.orderType == 'asc'"> order by ri.rent ${queryVo.orderType} </if> </select> <!-- 根据房间ID查询图片列表 --> <select id="selectGraphVoListByRoomId" resultType="com.atguigu.lease.web.app.vo.graph.GraphVo"> select id, name, item_type, item_id, url from graph_info where is_deleted = 0 and item_type = 2 and item_id = #{id} </select> <!-- 根据公寓ID查询标签列表 --> <select id="selectLabelInfoListByRoomId" resultType="com.atguigu.lease.model.entity.LabelInfo"> select id, type, name from label_info where is_deleted = 0 and id in (select label_id from room_label where is_deleted = 0 and room_id = #{id}) </select>知识点：

Mybatis-Plus分页插件注意事项
使用Mybatis-Plus的分页插件进行分页查询时，如果结果需要使用
<collection>进行映射，只能使用**嵌套查询（Nested Select for Collection），而不能使用嵌套结果映射（Nested Results for Collection）**。嵌套查询和嵌套结果映射是Collection映射的两种方式，下面通过一个案例进行介绍
例如有
room_info和graph_info两张表，其关系为一对多，如下
现需要查询房间列表及其图片信息，期望返回的结果如下
[ { "id": 1, "number": 201, "rent": 2000, "graphList": [ { "id": 1, "url": "http://", "roomId": 1 }, { "id": 2, "url": "http://", "roomId": 1 } ] }, { "id": 2, "number": 202, "rent": 3000, "graphList": [ { "id": 3, "url": "http://", "roomId": 2 }, { "id": 4, "url": "http://", "roomId": 2 } ] } ]为得到上述结果，可使用以下两种方式
-
嵌套结果映射
<select id="selectRoomPage" resultMap="RoomPageMap"> select ri.id room_id, ri.number, ri.rent, gi.id graph_id, gi.url, gi.room_id from room_info ri left join graph_info gi on ri.id=gi.room_id </select> <resultMap id="RoomPageMap" type="RoomInfoVo" autoMapping="true"> <id column="room_id" property="id"/> <collection property="graphInfoList" ofType="GraphInfo" autoMapping="true"> <id column="graph_id" property="id"/> </collection> </resultMap>这种方式的执行原理如下图所示
-
嵌套查询
<select id="selectRoomPage" resultMap="RoomPageMap"> select id, number, rent from room_info </select> <resultMap id="RoomPageMap" type="RoomInfoVo" autoMapping="true"> <id column="id" property="id"/> <collection property="graphInfoList" ofType="GraphInfo" select="selectGraphByRoomId" column="id"/> </resultMap> <select id="selectGraphByRoomId" resultType="GraphInfo"> select id, url, room_id from graph_info where room_id = #{id} </select>这种方法使用两个独立的查询语句来获取一对多关系的数据。首先，Mybatis会执行主查询来获取
room_info列表，然后对于每个room_info，Mybatis都会执行一次子查询来获取其对应的graph_info。
若现在使用MybatisPlus的分页插件进行分页查询，假如查询的内容是第1页，每页2条记录，则上述两种方式的查询结果分别是
- 嵌套结果映射
-
嵌套查询
显然嵌套结果映射的分页逻辑是存在问题的。
