Spring Controller to handle all requests not matched by other Controllers

Question

I have a series of Controllers with Request Mappings that match certain URL's. I also want a Controller that will match any other URL not matched by the other Controllers. Is there a way to do this in Spring MVC? For example, could i have a controller with @RequestMapping(value="**") and change the order in which Spring Controllers are processed so this Controller is processed last to catch all unmatched requests? Or is there another way to achieve this behaviour?

Solution 1

If your base url is like that= http://localhost/myapp/ where myapp is your context then myapp/a.html, myapp/b.html myapp/c.html will get mapped to the first 3 method in the following controller. But anything else will reach the last method which matches **. Please note that , if you put ** mapped method at the top of your controller then all request will reach this method.

Then this controller servrs your requirement:

@Controller
@RequestMapping("/")
public class ImportController{

    @RequestMapping(value = "a.html", method = RequestMethod.GET)
    public ModelAndView getA(HttpServletRequest req) {
        ModelAndView mv;
        mv = new ModelAndView("a");
        return mv;
    }

    @RequestMapping(value = "b.html", method = RequestMethod.GET)
    public ModelAndView getB(HttpServletRequest req) {
        ModelAndView mv;
        mv = new ModelAndView("b");
        return mv;
    }

    @RequestMapping(value = "c.html", method = RequestMethod.GET)
    public ModelAndView getC(HttpServletRequest req) {
        ModelAndView mv;
        mv = new ModelAndView("c");
        return mv;
    }

@RequestMapping(value="**",method = RequestMethod.GET)
public String getAnythingelse(){
return "redirect:/404.html";
}

Solution 2

@RequestMapping (value = "/**", method = {RequestMethod.GET, RequestMethod.POST})
public ResponseEntity<String> defaultPath() {
    LOGGER.info("Unmapped request handling!");
    return new ResponseEntity<String>("Unmapped request", HttpStatus.OK);
}

This will do the work with proper order of controller matching. It will be used when nothing is matched.

If I understand correctly, you want to handle all 404s? But possibly do something useful, rather than return 'not found'?

Yes your idea would work. Have you tried it? See github.com/stormpath/spring-mvc-rest-exhandler/blob/master/… for example

Yes, i want a way to process URL's not matched by any other Controller i have made.

[rurounisuikoden]

Wouldn't the default controller you have provided in that link be matched before other requestMappings?

After this configuration my swagger stopped working. github.com/springfox/springfox/issues/2532

[Mustofa Rizwan]

use @RequestMapping("/anything/") instead of @RequestMapping("/") for this configuraration

[Kanagavelu Sugumar]

But that will handle only non mapped requests under /anything

[Mustofa Rizwan]

then remove the last method from this class value="**", and use custom exception handler... which will make sure that any non mapped request goes to a certain 404 page

[Kanagavelu Sugumar]

Exception handler wont solve my problem, want to handle it inside @RequestMapping method. Anyhow Thanks & plus1.

This is problematic. For some reason, this controller method catches request to static resources too.
