I use a global exception handler built by @ControllerAdvice as shown below and I catch custom exception e.g. NoSuchElementFoundException without any problem. If there is any uncaught error, then handleAllUncaughtException catches them.
On the other hand, I created 2 other custom exception classes to catch MaxUploadSizeExceededException and FileSizeLimitExceededException. But I cannot catch the error by these methods and catch by handleAllUncaughtException.
Here is the error details:
@RestControllerAdvice
public class DefaultExceptionHandler extends ResponseEntityExceptionHandler {
// for NoSuchElementFoundException
@ExceptionHandler(NoSuchElementFoundException.class)
@ResponseStatus(HttpStatus.NOT_FOUND)
public ResponseEntity<Object> handleNoSuchElementFoundException(NoSuchElementFoundException ex,
WebRequest request) {
log.error(FAILED_TO_FIND_ELEMENT, ex);
return buildErrorResponse(ex, HttpStatus.NOT_FOUND, request);
}
// I am trying to catch the custom exception using one of these methods:
// MaxUploadSizeExceededException and FileSizeLimitExceededException
@ExceptionHandler(MaxUploadSizeExceededException.class)
@ResponseStatus(HttpStatus.PAYLOAD_TOO_LARGE)
public ResponseEntity<Object> handleMaxUploadSizeExceededException(MaxUploadSizeExceededException ex,
WebRequest request) {
return buildErrorResponse(ex, HttpStatus.PAYLOAD_TOO_LARGE, request);
}
@ExceptionHandler(FileSizeLimitExceededException.class)
@ResponseStatus(HttpStatus.PAYLOAD_TOO_LARGE)
public ResponseEntity<Object> handleFileSizeLimitExceededException(FileSizeLimitExceededException ex,
WebRequest request) {
return buildErrorResponse(ex, HttpStatus.PAYLOAD_TOO_LARGE, request);
}
// for all Uncaught Exceptions
@ExceptionHandler(Exception.class)
@ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)
public ResponseEntity<Object> handleAllUncaughtException(Exception ex,
WebRequest request) {
return buildErrorResponse(ex, UNKNOWN_ERROR, HttpStatus.INTERNAL_SERVER_ERROR, request);
}
// code omitted
}
My custom exception classes are similar to NoSuchElementFoundException, and there is nothing wrong related to these classes. Here is one of them:
public class MaxUploadSizeExceededException extends RuntimeException {
public MaxUploadSizeExceededException(String message) {
super(message);
}
}
1. So, which exception type (MaxUploadSizeExceededException or FileSizeLimitExceededException) should I use for creating custom class and how to catch catch this error in my custom method?
2. Is the HTTP status code (PAYLOAD_TOO_LARGE) correct?
Update: Here is stack trace:

CodePudding user response：
Your custom exception classes are not getting called anywhere, If you have declared any custom exception class and you want it to be handled accordingly you need to throw them as per below example.
Custom Exception Class
public class CustomMaxUploadSizeExceededException extends RuntimeException {
public CustomMaxUploadSizeExceededException (String message) {
super(message);
}
}
Service Class
class FileuploadServiceImpl {
public UploadResponse uploadFile() {
//do some validation on file size
if (validate) {
//process normally
} else {
throw MaxUploadSizeExceededException("File size exceeded the permitted limit");
}
}
}
ExceptionHandlerAdvice
@RestControllerAdvice
@Slf4j
public class CustomExceptionHandler {
@ExceptionHandler(CustomMaxUploadSizeExceededException.class)
@ResponseStatus(HttpStatus.PAYLOAD_TOO_LARGE)
public ResponseEntity<Object> handleMaxUploadSizeExceededException(CustomMaxUploadSizeExceededException ex, WebRequest request) {
log.error(ex.getMessage(), ex);
return buildErrorResponse(ex, ex.getMessage(), request);
}
}
Another approach would be to just try to add method resolving to exception thrown as per your stacktrace which is MaxUploadSizeExceededException as below
@ExceptionHandler(MaxUploadSizeExceededException.class)
@ResponseStatus(HttpStatus.PAYLOAD_TOO_LARGE)
public ResponseEntity<Object> handleMaxUploadSizeExceededException(MaxUploadSizeExceededException ex, WebRequest request) {
log.error(ex.getMessage(), ex);
return buildErrorResponse(ex, ex.getMessage(), request);
}
