How to return message in Resposne Body?-CodePudding

I have to retuen the message "Data Added" in the api in ResponseBody Create a api while enters student data /newStudent

Request Body:

{
"name":"Shubham",
"rollno":22,
"studentid":1
}

Response:

{
"status":"OK",
"message":"Data Added"
}

@RequestMapping("/studentdata")
@ResponseBody
@ResponseStatus(HttpStatus.OK )

CodePudding user response：

You can create a custom response class that looks like this:

class CustomResponse {
   private String status;
   private String message;
   // Constructor/Getters/Setters
}

Then in your controller return ResponseEntity for example:

CustomResponse response = new CustomResponse("OK", "Data Added");
return ResponseEntity.ok(response); // the ok will return HTTP Status 200

Or if you want another HttpStatus, then you can use for example:

return new ResponseEntity<>(response, HttpStatus.CREATED);
                                      ^^^^^^^^^^^^^^^^^^

This is how to return custom object in response.

router.post("/newStudent", async (req, res) => {
  const { name, rollNo, studentId } = req.data;

  // POST data to DB
  const result = await AddStudentDataToDB({ name, rollNo, studentId });

  res.status(200).json({
    status: 'ok',
    message: 'Data Added'
  });
});

CodePudding user response：

First of all you should create a Response class which will hold status code and your custom message like the following class :

@Data
@AllArgsConstructor
@NoArgsConstructor
public class Response {
  private String statusCode;
  private String statusMsg;
}

So in your controller where you post the object use ResponseEntity which can allow you to customize HTTP response methods. For example:

 @Autowired
 private StudentRepository studentRepository;

 @PostMapping("/newStudent")
 public ResponseEntity<Response> saveEmployee(@RequestBody Student 
  student){
    studentRepository.save(student);
    Response response = new Response();
    response.setStatusCode("200");
    response.setStatusMsg("Your message");
    return ResponseEntity.status(HttpStatus.CREATED).body(response);
}
