响应实体<errorresponse>没有作为自定义 HTTP 响应正文返回</errorresponse>

Question

ErrorResponse class:

public class ErrorResponse {
    private String errorCode;
    private String errorMessage;
    ...
}

Controller Advice:

@ExceptionHandler(BaseException.class)
    public ResponseEntity<Object> handleBaseException(BaseException exception) {
        ErrorResponse res = new ErrorResponse(exception.getErrorCode().toString(),exception.getMessage());
        return new ResponseEntity<>(res, HttpStatus.NOT_FOUND);
    }

Http response:

{
    "timestamp": 1661865968618,
    "status": 500,
    "error": "Internal Server Error",
    "message": "custom message",
    "path": "...."
}

Expected Http response:

{
    "errorCode": "...",
    "errorMessage": "..."
}

Can anyone help me with the return statement of @controlleradvice such that I can get the expected Http response?

Answer 1

@ExceptionHandler(BaseException.class)
    public ResponseEntity<?> handleBaseException(HttpServletRequest request, BaseException exception) {
    return ResponseEntity
    .status(HttpStatus.NOT_FOUND)
    .body(new ErrorResponse(HttpStatus.NOT_FOUND, exception.getMessage()), String.valueOf(request.getAttribute(HandlerMapping.BEST_MATCHING_PATTERN_ATTRIBUTE)));
)
