@ExceptionHandler 没有捕获 HttpMessageNotReadableException

Question

I have the following exception handler:

@ControllerAdvice
public class MyExceptionHandler {
  private static final Logger logger = LoggerFactory.getLogger(MyExceptionHandler.class);
    @ExceptionHandler
    @ResponseStatus(HttpStatus.BAD_REQUEST)
    public void handle(HttpMessageNotReadableException e) {
        logger.warn("HttpMessageNotReadableException occurred.", e);
        throw e;
    }

But it doesn't catch HttpMessageNotReadableException ?! In my logs I see (it prints spring itself):

2017-07-04 13:26:38,699 DEBUG org.springframework.web.servlet.mvc.method.annotation.ServletInvocableHandlerMethod.getMethodArgumentValues:164 - Failed to resolve argument 0 of type 'com.finvale.model.Client'

Is it possible to catch this exception in my ExceptionHandler ?

PS

I agree that my code contains mistake. I neeed to specify type in annotation. I changed it like this:

 @ExceptionHandler(HttpMessageNotReadableException.class)
    @ResponseStatus(HttpStatus.BAD_REQUEST)
    public void handle(HttpMessageNotReadableException e) {

but I still see same behaviour.

handle method doesn't invoke

Answer 1

You have to specify the class that the handler needs to handle. Like:

@ExceptionHandler(HttpMessageNotReadableException.class)

See here for further reading for example. Or there for a "complete" discussion regarding spring and exception handling.

Answer 2

Finally I found solution:

Root cause was that there was 2 places with @ExceptionHandler

• Inside controller
• Inside the Separated class MyExceptionHandler described in question.

I moved method to MyExceptionHandler ans it became working.

Answer 3

Change @ExceptionHandler to @ExceptionHandler(value = HttpMessageNotReadableException.class)

And instead of re-throwing same exception, its better to return a custom object containing that error message in meaningful way

Answer 4

Mine worked after I imported the class.In the beginning it was not recognizing the class. But it worked after importing import org.springframework.http.converter.*;
