Question

i need to catch all exceptions of my controllers to a exception controller. How to configure spring?
I need this because every request to my webapp are json request and in case of exception i need to answer with a genericc {success: false, exception: “String ex…”}. But i can not understand if the better way is to use SimpleMappingExceptionResolver.

Thank you.

If you want to write a custom response, it would be more interesting to use a custom HandlerExceptionResolver implementation.

spring configuration:

<bean id="exceptionHandler" class="com.am.CustomHandlerExceptionResolver"/>

java:

public class CustomHandlerExceptionResolver
    implements HandlerExceptionResolver {

    @Override
    public ModelAndView resolveException(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) {
        //write in response
        return null;
    }

}
