Spring MVC 3 User Defined Exception handling with User defined View

Question

How to handle user defined exceptions (Custom Exception ex.: "BusinessException") in Spring MVC 3 with custom message and view name ?

For Example :

If i throw my own exception from Service layer it should be caught and should redirect to specified view with message, the view name may be same or different.

I searched in Google, but no luck.

Thanks.

Answer 1

Have you checked @ExceptionHandler

for eg :

@ExceptionHandler(MyBusinessException.class)
public ModelAndView handleMyBusinessException(MyBusinessException e) {
   handle it or log it or redirect to error page after populating a model
}

This has advantage of having Exception handled at Spring MVC level itself , you can populate a model and bring up a meaningful error page.

Otherwise you can configure it in web.xml as other answer suggests. But your error page will be more like a static page.

Answer 2

You have to propagate exception from service layer to controller layer there you can usedeclarative exception handling and provide exception to view mapping in spring configuration xml
