Spring Mvc 404 Not Found
exceptions thrown by my web app, in my case my app returns JSON response with HTTP status for error responses to the client. However, I am trying to figure out how to handle error 404 to return a similar JSON response like with the one handled by @ExceptionHandler Update: I mean, when a URL that does not exist is accessed java spring spring-mvc share|improve this question edited Nov 13 '12 at 8:09 asked nohandlerfoundexception Nov 13 '12 at 6:45 xybrek 8,65025142277 add a comment| 4 Answers 4 active oldest votes up vote 3 down vote accepted Simplest way to find out is use the following: @ExceptionHandler(Throwable.class) public String handleAnyException(Throwable ex, HttpServletRequest request) { return ClassUtils.getShortName(ex.getClass()); } If the URL is within the scope of DispatcherServlet then any 404 caused by mistyping or anything else will be caught by this method but if the URL typed is beyond the URL mapping of the DispatcherServlet then you have to either use:

There is no web.xml. The app is configured by using instance of AbstractAnnotationConfigDispatcherServletInitializer and WebMvcConfigurerAdapter like so, @Configuration @EnableWebMvc @ComponentScan(basePackages = {"com.example.*"}) @EnableTransactionManagement @PropertySource("/WEB-INF/properties/application.properties") public class WebAppConfig extends WebMvcConfigurerAdapter { ... } and public class WebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer { ... } I am now trying to add a global/catch-all exception handler for 404 pages i.e. HttpStatus.NOT_FOUND but no success. Below are some of the ways I tried. import org.springframework.http.HttpStatus; import org.springframework.web.bind.annotation.ControllerAdvice; import org.springframework.web.bind.annotation.ExceptionHandler; import org.springframework.web.bind.annotation.ResponseStatus; import org.springframework.web.servlet.ModelAndView; import org.springframework.web.servlet.NoHandlerFoundException; import org.springframework.web.servlet.mvc.multiaction.NoSuchRequestHandlingMethodException; @ControllerAdvice public class GlobalExceptionHandlerController { @ExceptionHandler @ResponseStatus(HttpStatus.NOT_FOUND) public ModelAndView handleException (NoSuchRequestHandlingMethodException ex) { ModelAndView mav = new ModelAndView(); return mav; } @ExceptionHandler @ResponseStatus(HttpStatus.NOT_FOUND) public ModelAndView handleExceptiond (NoHandlerFoundException ex) { ModelAndView mav = new ModelAndView(); return mav; } @ResponseStatus(HttpStatus.NOT_FOUND) @ExceptionHandler(NoHandlerFoundException.class) public void handleConflict() { } @ResponseStatus(HttpStatus.NOT_FO
exception handling but, when teaching Spring MVC, I often find that my students are confused or not comfortable https://spring.io/blog/2013/11/01/exception-handling-in-spring-mvc with them. Today I’m going to show you the various options available. Our goal is to not handle exceptions explicitly in Controller methods where possible. http://www.journaldev.com/2651/spring-mvc-exception-handling-controlleradvice-exceptionhandler-handlerexceptionresolver They are a cross-cutting concern better handled separately in dedicated code. There are three options: per exception, per controller or globally. A demonstration application that 404 error shows the points discussed here can be found athttp://github.com/paulc4/mvc-exceptions. See Sample Application below for details. NOTE: The demo applications has been revamped and updated (October 2014) to use Spring Boot 1.1.8 and is (hopefully) easier to use and understand.Using HTTP Status Codes Normally any unhandled exception thrown when processing a web-request spring mvc 404 causes the server to return an HTTP 500 response. However, any exception that you write yourself can be annotated with the @ResponseStatus annotation (which supports all the HTTP status codes defined by the HTTP specification). When an annotated exception is thrown from a controller method, and not handled elsewhere, it will automatically cause the appropriate HTTP response to be returned with the specified status-code. For example, here is an exception for a missing order. @ResponseStatus(value=HttpStatus.NOT_FOUND, reason="No such Order") // 404 public class OrderNotFoundException extends RuntimeException { // ... } And here is a controller method using it: @RequestMapping(value="/orders/{id}", method=GET) public String showOrder(@PathVariable("id") long id, Model model) { Order order = orderRepository.findOrderById(id); if (order == null) throw new OrderNotFoundException(id); model.addAttribute(order); return "orderDetail"; } A familiar HTTP 404 response will be returned if the URL handled by this method includes an unknown order id.Controller Based Exception HandlingUsing @ExceptionHandler You can add extra (@Ex

Today we will look into Spring Exception Handling using @ExceptionHandler, @ControllerAdvice and HandlerExceptionResolver. Any web application requires good design for exception handling because we don't want to serve container generated page when any unhandled exception is thrown by our application.Spring Exception HandlingHaving a well defined exception handling approach is a huge plus point for any web application framework, that being said Spring MVC framework delivers well when it comes to exception and error handling in our web applications.Spring MVC Framework provides following ways to help us achieving robust exception handling.Controller Based - We can define exception handler methods in our controller classes. All we need is to annotate these methods with @ExceptionHandler annotation. This annotation takes Exception class as argument. So if we have defined one of these for Exception class, then all the exceptions thrown by our request handler method will have handled.These exception handler methods are just like other request handler methods and we can build error response and respond with different error page. We can also send JSON error response, that we will look later on in our example.If there are multiple exception handler methods defined, then handler method that is closest to the Exception class is used. For example, if we have two handler methods defined for IOException and Exception and our request handler method throws IOException, then handler method for IOException will get executed.Global Exception Handler - Exception Handling is a cross-cutting concern, it should be done for all the pointcuts in our application. We have already looked into Spring AOP and that's why Spring provides @ControllerAdvice annotation that we can use with any class to define our global exception handler.The handler methods in Global Controller Advice is same as Controller based exception handler methods and used when controller class is not able to handle the exception.HandlerExceptionResolve
