Spring mvc controller handling all request and should not do that

Question

I have two controllers:

UserController and AdminController.

The AdminController is handling all requests that have not created. Also handle the request to access to my resources.

Also I'm using spring-security and maven to compile all.

Examples:

Request: .../appName/login --> return login view.
Request: .../appName/home --> return home view.
Request: .../appName/fahsjhgasghdjfg --> return admin view.
Request: .../appName/dasjdha/fhfashjfs --> return admin view.
Request: .../appName/resources/css/one.css --> return admin view.

If I remove the AdminController and create a new controller with name ExamplefasjkasController it happens the same.

Code:

Controllers:

@Controller
public class AdminController {

    @RequestMapping(name = "/panel")
    public ModelAndView adminPanel() {
        return new ModelAndView("admin");
    }

}

@Controller
public class UserController extends GenericController {

    @Autowired
    private IUserService userService;

    @RequestMapping(value = { "/", "/home" })
    public ModelAndView home(HttpServletRequest request, Principal principal) {

        ModelAndView model = new ModelAndView(Name.VIEW_HOME);
        model.setViewName(Name.VIEW_HOME);

        return model;
    }

    @RequestMapping(value = "/login", method = RequestMethod.GET)
    public ModelAndView login(HttpServletRequest request,
            @RequestParam(value = Name.PARAM_ERROR, required = false) String error,
            @RequestParam(value = Name.PARAM_LOGOUT, required = false) String logout) {

        ModelAndView model = new ModelAndView();
        model.setViewName(Name.VIEW_LOGIN);

        if (error != null) {
            addError(model, getErrorMessage(request, "SPRING_SECURITY_LAST_EXCEPTION"));
        }

        if (logout != null) {
            addInfo(model, Message.INFO_USER_LOGOUT);
        }

        return model;
    }
}

In the AdminController I try to get Request with

@Controller
@RequestMapping(name = "/admin"}
public class AdminController {

    @RequestMapping(name = "/panel")
    ...

}

But I get an exception:

javax.servlet.ServletException: No adapter for handler [com.base.controller.AdminController@3f114da7]: The DispatcherServlet configuration needs to include a HandlerAdapter that supports this handler

        <property name="suffix">
            <value>.jsp</value>
        </property>
    </bean>

I could share the entire application if someone request. Thanks in advance and best regards.

You have to fix your request mapping as below:

@Controller
@RequestMapping(value = "/admin"}
public class AdminController {

    @RequestMapping(value = "/panel")
    ...

}
