小知识点
- Map有getOrDefault("1","0");取不到取默认值
- 两个不同对象，属性相同进行赋值转换，使用modelMapper
<dependency>
<groupId>org.modelmapper</groupId>
<artifactId>modelmapper</artifactId>
<version>1.1.0</version>

- controller请求中BindingResult bindingResult通过bindingResult.hasErrors()判断是否报错，下列模板代码可以学习
/**
* 新增房源接口
* @param houseForm
* @param bindingResult
* @return
*/
@PostMapping("admin/add/house")
@ResponseBody
public ApiResponse addHouse(@Valid @ModelAttribute("form-house-add") HouseForm houseForm, BindingResult bindingResult) {
if (bindingResult.hasErrors()) {
return new ApiResponse(HttpStatus.BAD_REQUEST.value(), bindingResult.getAllErrors().get(0).getDefaultMessage(), null);
}
if (houseForm.getPhotos() == null || houseForm.getCover() == null) {
return ApiResponse.ofMessage(HttpStatus.BAD_REQUEST.value(), "必须上传图片");
}
Map<SupportAddress.Level, SupportAddressDTO> addressMap = addressService.findCityAndRegion(houseForm.getCityEnName(), houseForm.getRegionEnName());
if (addressMap.keySet().size() != 2) {
return ApiResponse.ofStatus(ApiResponse.Status.NOT_VALID_PARAM);
}
ServiceResult<HouseDTO> result = houseService.save(houseForm);
if (result.isSuccess()) {
return ApiResponse.ofSuccess(result.getResult());
}
return ApiResponse.ofSuccess(ApiResponse.Status.NOT_VALID_PARAM);
}
