Exception handler in Spring MVC

Question

I want to create an exception handler which will intercept all controllers in my project. Is that possible to do? Looks like I have to put a handler method in each controlle

Answer 1

Since Spring 3.2 you can use @ControllerAdvice annotation. You can declare an @ExceptionHandler method within an @ControllerAdvice class in which case it handles exceptions from @RequestMapping methods from all controllers.

@ControllerAdvice
public class MyGlobalExceptionHandler {

    @ExceptionHandler(value=IOException.class)
    public @ResponseBody String iOExceptionHandler(Exception ex){
        //
        //
    }

    // other exception handler methods
    // ...

}
