Spring發送不同的響應

Question

如果使用Spring框架有不同的錯誤，我該如何發送不同的答案？

@RestController 
public class MainController{ 

    @RequestMapping("/login") 
    public Object login(){ 

    } 
} 

Answer 1

您可以使用異常處理後這個

@RequestMapping(value = "login", method = RequestMethod.POST) 
@ResponseBody 
public LoginResponse login(@RequestBody SignInRequest request) throws EmailNotValidException { 
    if (isValidEmailAddress(request.getEmail())) throw new EmailNotValidException(); 

    return response; 
} 

，你可以寫法@ExceptionHandler註釋

@ExceptionHandler({EmailNotValidException.class,DataAccessException.class}) 
    public ResponseEntity<BaseResponse> dummyExceptionHandler() { 
     return new ResponseEntity<>(new BaseResponse("error"), HttpStatus.BAD_REQUEST); 
    }
