Spring MVC REST Handing Bad Url (404) by returning JSON

Question

I am developing a REST service using SpringMVC, where I have @RequestMapping at class and method level.

This application is currently configured to return error-page js

Answer 1

you can return json in the location below,that /handle/404.

    404
    /handle/404

after you config this in web.xml,a 404 error will redirect to /handle/404,and you can create a controller with this mapping and return a json result. for example.

@RestController
@RequestMapping(value = "handle")
public class HttpErrorController {
   @RequestMapping(value = "404")
   public String handle404() {
      return "404 error";
   }
}
