Handling “No mapping found for HTTP request in DispatcherServlet” situation

Question

I've been trying to handle globally a situation when my dispatcher servlet doesn't have defined mapping for requested url but haven't found the solution yet.

Here's my class for handling global exceptions:

@ControllerAdvice
public class GlobalExceptionHandlerController {

@Value("${exception.view.default}")
private String defaultExceptionView;

private static final Logger LOGGER = Logger.getLogger(GlobalExceptionHandlerController.class);

@ExceptionHandler(Exception.class)
public ModelAndView notFoundException(Exception e) {
    LOGGER.error("Error ocurred: " + e.getMessage());
    return new ModelAndView(defaultExceptionView)
            .addObject("code", "404")
            .addObject("name", "Page Not Found")
            .addObject("message", "We couldn't find requested resource");
    }
}

I tried many different classes within @ExceptionHandler but nothing worked for me. The handler works fine - when I throw exception from one of the controllers and it isn't handled locally it goes straight to this global handler.

Is there a way to perform that kind of exception handling by @ControllerAdvice?

Answer 1

Yes, configure your DispatcherServlet with setThrowExceptionIfNoHandlerFound which sets

[...] whether to throw a NoHandlerFoundException when no Handler was found for this request. This exception can then be caught with a HandlerExceptionResolver or an @ExceptionHandler controller method.

and do what it says, ie. define an @ExceptionHandler for a NoHandlerFoundException exception.
