Spring-MVC：无论链接是什么，都将重定向到主页。

我们有一个维护spring-MVC应用程序，当请求域名说我们正在维护时，它仅显示一个图像。是否有某种方法可以将所有请求的url路由为当前域名称的“ /”。de/something in 404。

控制器代码：

@Controller
public class MaintenanceController {

        @RequestMapping(value ="/")
        public String loadMaintenancePage(Model model){
            return "maintenance";
        }
}
