Question

我希望JSON响应采用某种格式。

这是我的公司，LocationInfo看起来像

public class Company {
   private List<LocationInfo> companies;
   // gettts and setters
}

公共类LocationInfo {

  private String localCompanyID;
  private String localCompanyName;

  // gettts and setters

}

我的控制器如下所示

 @GetMapping(value = "/url", produces = MediaType.APPLICATION_JSON_VALUE)
 public ResponseEntity<LocationInfo> getLocationMaster() {
     ResponseEntity response;
     List<LocationInfo> companies = getAllCompanies();
     // some code goes here
     response = new ResponseEntity<>(localCompanies, HttpStatus.OK);
     return response;
 }

这就是我要得到的

 [
    {
      "localCompanyID": "33",
      "localCompanyName": "Company-A"
    },
    {
      "localCompanyID": "45",
      "localCompanyName": "Company-B"
    }
 ]

我希望答复如下。

{
  "localCompanies": [
   {
     "localCompanyID": "33",
     "localCompanyName": "Company-A"
   },
   {
     "localCompanyID": "45",
     "localCompanyName": "Company-B"
   }
 ]

}

谢谢。

创建一个响应DTO类并将您的列表添加到其中：

@AllArgsConstructor(staticName = "of")
class LocalCompaniesResponseDto {
  List<LocationInfo> localCompanies;
}

new ResponseEntity<>(LocalCompaniesResponseDto.of(localCompanies), HttpStatus.OK)

如何实现我的JSON格式为特定格式？
