Receiving error Failed to invoke @ExceptionHandler even with a custom @ControllerAdvice defined

Question

I have an app with Spring 4.1.6 where I created a class for handling all exceptions as follow:

@ControllerAdvice
public class RestControllerAdvice {
...
@ExceptionHandler({Exception.class})
public ResponseEntity<Result> handleException(final Exception ex) {
    Result res = new Result();
    try {
        Exception root = (Exception) ExceptionUtils.getRootCause(ex);
        if (root == null) {
            root = ex;
        }
        if (root instanceof BindException) {
            handleBindException(root, res);
        } else if (root instanceof ConstraintViolationException) {
            handleConstraintViolations(root, res);
        } else if (root instanceof NoHandlerFoundException) {
            handleNoHandlerFoundException(root, res);
        } else {
            logError(res, ex);
        }
    } catch (Exception e) {
        logError(res, e);
    } finally {
        if (!res.hasErrors()) {
            handleUnexpected(res);
        }
    }
    return new ResponseEntity<Result>(res, OK);
}
}

I realised that even though I can capture the exceptions, along with the exception in question I receive an additional error message saying the following:

ERROR o.s.w.s.m.m.a.ExceptionHandlerExceptionResolver - Failed to invoke @ExceptionHandler method: 
  public org.springframework.http.ResponseEntity<com.foo.Result> 
   com.foo.RestControllerAdvice.handleException(java.lang.Exception)

Even though this is not impeditive at any level, I'd like to understand why this is happening. Can someone please explain this to me?

Thanks.

Answer 1

You may catch the specific exception right away.

org.apache.catalina.connector.ClientAbortException

@ExceptionHandler(ClientAbortException.class)
public void handleClientAbortException(ClientAbortException e) {
    log.warn(e.getMessage();
}

Answer 2

IOException: Broken pipe indicates that the client closed the connection. You caught the exception successfully, but you are trying to return a response to the client in the last line. I've managed to handle it properly with following exception handler:

@ExceptionHandler(IOException.class)
@ResponseStatus(HttpStatus.SERVICE_UNAVAILABLE)
public Object exceptionHandler(IOException e) {
    if (StringUtils.containsIgnoreCase(ExceptionUtils.getRootCauseMessage(e), "Broken pipe")) { 
      return null;        //socket is closed, cannot return any response    
    } else {
      return new HttpEntity<>(e.getMessage()); 
    }
}
