Spring 3.2 servlet 3.0 Java Config (no web.xml) how to create a custom 404 handler

Question

What options do I need to catch and process 404 without using web.xml . This is how I define my servlet:

 @Order(1) public class MyWebApplicationInitializer extends AbstractAnnotationConfigDispatcherServletInitializer { // 10MB private static final int MAX_UPLOAD_SIZE_IN_MB = 10 * 1024 * 1024; @Override protected Class<?>[] getRootConfigClasses() { return new Class[] { RootConfiguration.class }; } @Override protected Class<?>[] getServletConfigClasses() { return new Class[] { WebConfiguration.class }; } @Override protected String[] getServletMappings() { return new String[] { "/" }; } @Override protected Filter[] getServletFilters() { return new Filter[] { new SiteMeshFilter() }; } @Override protected void customizeRegistration(ServletRegistration.Dynamic registration) { MultipartConfigElement multipartConfigElement = new MultipartConfigElement("/tmp", MAX_UPLOAD_SIZE_IN_MB, MAX_UPLOAD_SIZE_IN_MB * 2, MAX_UPLOAD_SIZE_IN_MB / 2); registration.setMultipartConfig(multipartConfigElement); } } 

My application is configured in java code, @ControllerAdvice works fine with all other exceptions, for example:

 BindException.class, MethodArgumentNotValidException.class, MissingServletRequestParameterException.class, MissingServletRequestPartException.class, HttpMessageNotReadableException.class, TypeMismatchException.class 

but

 @ControllerAdvice public class SomeClass { ... @ExceptionHandler(value = { ResourceNotFoundException.class, NoSuchRequestHandlingMethodException.class }) public ModelAndView handle404() { ModelAndView modelAndView = new ModelAndView(); modelAndView.setViewName("/errors/404"); modelAndView.addObject("exception", "404 NOT FOUND!"); return modelAndView; } ... } 

NOT catching 404 I also tried HttpStatus ... no luck

when I call / someUrlThatDoesNotExist:

 [DEBUG] 2014-01-24 10:03:16,639 org.springframework.security.web.FilterChainProxy doFilter - /someUrlThatDoesNotExist reached end of additional filter chain; proceeding with original chain [DEBUG] 2014-01-24 10:03:16,640 org.springframework.web.servlet.DispatcherServlet doService - DispatcherServlet with name 'dispatcher' processing GET request for [/someUrlThatDoesNotExist] [DEBUG] 2014-01-24 10:03:16,641 org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping getHandlerInternal - Looking up handler method for path /someUrlThatDoesNotExist [DEBUG] 2014-01-24 10:03:16,662 org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping getHandlerInternal - Did not find handler method for [/someUrlThatDoesNotExist] [WARN] 2014-01-24 10:03:16,663 org.springframework.web.servlet.PageNotFound noHandlerFound - No mapping found for HTTP request with URI [/someUrlThatDoesNotExist] in DispatcherServlet with name 'dispatcher' [DEBUG] 2014-01-24 10:03:16,665 org.springframework.web.servlet.DispatcherServlet processRequest - Successfully completed request 

but when I try to check below points using AOP:

 org.springframework.web.servlet.mvc.support.DefaultHandlerExceptionResolver.handleHttpRequestMethodNotSupported(..) org.springframework.web.servlet.mvc.support.DefaultHandlerExceptionResolver.handleNoSuchRequestHandlingMethod(..) 

they never hit.

I believe that you need to configure DispatcherServlet to throw an exception if a handler is not found.

 dispatcherServlet.setThrowExceptionIfNoHandlerFound(true); 

and then @ControllerAdvice declare @ExceptionHandler for an exception of type NoHandlerFoundException .
