【尚庭公寓SpringBoot + Vue 项目实战】预约看房与租约管理（完结）

---

1、业务说明

预约看房管理共需三个接口，分别是保存或更新看房预约、查询个人预约列表和根据ID查询预约详情信息

租约管理共有六个接口，分别是获取个人租约基本信息列表**、**根据ID获取租约详细信息、根据ID更新租约状态、保存或更新租约、根据房间ID获取可选支付方式和根据房间ID获取可选租期

2、接口开发

2.1、预约看房管理

首先在ViewAppointmentController中注入ViewAppointmentService，如下

@Tag(name = "看房预约信息")
@RestController
@RequestMapping("/app/appointment")
public class ViewAppointmentController {@Autowiredprivate ViewAppointmentService service;
}

2.1.1.保存或更新看房预约

在ViewAppointmentController中增加如下内容

@Operation(summary = "保存或更新看房预约")
@PostMapping("/saveOrUpdate")
public Result saveOrUpdate(@RequestBody ViewAppointment viewAppointment) {viewAppointment.setUserId(LoginUserHolder.getLoginUser().getUserId());service.saveOrUpdate(viewAppointment);return Result.ok();
}

2.1.2. 查询个人预约看房列表

• 查看响应的数据结构

  查看web-app模块下的com.atguigu.lease.web.app.vo.appointment.AppointmentItemVo，如下

  @Data
  @Schema(description = "APP端预约看房基本信息")
  public class AppointmentItemVo {@Schema(description = "预约Id")private Long id;@Schema(description = "预约公寓名称")private String apartmentName;@Schema(description = "公寓图片列表")private List<GraphVo> graphVoList;@Schema(description = "预约时间")@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")private Date appointmentTime;@Schema(description = "当前预约状态")private AppointmentStatus appointmentStatus;
