Spring Controller to handle all requests that do not match other controllers

I have a series of controllers with query mappings that match specific URLs. I also want the controller to match any other URL that does not match with other controllers. Is there a way to do this in Spring MVC? For example, can I have a controller with @RequestMapping (value = "**") and change the processing order of the Spring controllers so that this controller is processed last to catch all unsurpassed requests? Or is there another way to achieve this behavior?

If your base url looks like this: http: // localhost / myapp / , where myapp is your context, then myapp / a.html, myapp / b.html myapp / c.html will be mapped to the first method 3 in the next controller. But everything else will reach the last method that matches **. Note that if you put the ** associated method at the top of your controller, then the whole request will reach that method.

Then this controller will fulfill 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";
}

@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 job with the correct controller matching order. It will be used when nothing matches.
