Spring mvc Controller 处理所有请求，不应该那样做

Question

我有两个 Controller :

用户 Controller 和管理 Controller 。

AdminController 正在处理所有尚未创建的请求。还处理访问我的资源的请求。

另外，我正在使用 spring-security 和 maven 来编译所有内容。

例子:

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.

如果我删除 AdminController 并创建一个名为 ExamplefasjkasController 的新 Controller ，它会发生相同的情况。

代码:

Controller :

@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;
    }
}

在 AdminController 中，我尝试通过以下方式获取请求

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

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

}

但我得到一个异常(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

您必须按如下方式修复您的请求映射:

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

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

}
