Spring 3 Controller Exception handler implementation problems
- by predhme
I was hoping to implement a single "ExceptionController" to handle exceptions that are thrown in execution of my other controllers' methods. I hadn't specified any HandlerExceptionResolver in my application context so according to the API documentation the AnnotationMethodHandlerExceptionResolver should be started. Verified as such in the source. So I am curious to know why the following isn't working.
@Controller
public class ExceptionController {
@ExceptionHandler(NullPointerException.class)
public ModelAndView handleNullPointerException(NullPointerException ex) {
// Do some stuff
log.error(logging stuff)
return myModelAndView;
}
}
@Controller
public class AnotherController {
@RequestMapping(value="/nullpointerpath")
public String throwNullPointer() {
throw new NullPointerException();
}
}
I see in the debug logs that the three default exception handlers are asked for handling of the exception, but nothing is done and I see "DispatcherServlet - Could not complete request". Followed by the user being displayed the stacktrace and a 500 Internal error.
