后端中的核心代码
1. 控制层代码
BusinessException异常是自定义的异常类型
CommonResponseUtils、ConversionUtils是自定义的工具类
以上代码在本博客均未列出
* @param commonRequest 前端请求
* @return 返回给前端的数据
*/
@PostMapping(value = "/queryByCondition")
public CommonResponse> queryByCondition(@RequestBody CommonRequest commonRequest){
CommonRequestUtils.checkCommonRequest(commonRequest);
try {
OrganizationDTO dto = (OrganizationDTO) ConversionUtils.convertSimpleObject(commonRequest.getBody(),OrganizationDTO.class);
PageInfo dtoPageInfo = organizationService.queryByCondition(dto);
List dtoList = dtoPageInfo.getList();
List vos = ConversionUtils.convertSimpleList(dtoList, OrganizationDataListVO.class);
PageInfo voPageInfo = (PageInfo) ConversionUtils.convertSimpleObject(dtoPageInfo, PageInfo.class);
voPageInfo.setList(vos);
return CommonResponseUtils.makeSuccessCommonResponse(voPageInfo, "0", null, null, null);
} catch (ServiceException exception) {
throw new BusinessException(exception);
} catch (IllegalAccessException | InstantiationException e) {
throw new BusinessException(SystemExceptionEnum.SYSTEM_ERROR);
}
}

Condition condition = new Condition(Organization.class);
Example.Criteria criteria = condition.createCriteria();
if (!StringUtils.isEmpty(organizationDTO.getName())) {
criteria.andLike("name", organizationDTO.getName() + "%");
