angular js spring mvc ui-router 路由冲突

参考了别人的例子，刷新是个特例。

在使用angular ui router 以后，界面浏览器会重定向，当使用F5刷新之后，界面没有走angualr的路由，而是请求服务器，所以服务器后台 web.xml 配置url mapping , 以/ang/*请求的就
跳转到默认界面。

$urlRouterProvider.otherwise('home');
    $stateProvider
        .state("home", {
            url:"/ang/home",
            templateUrl: "index.html"
        })
        .state("login", {
            url:"/ang/login",
            templateUrl: "views/login.html"
        })

    <servlet-name>springmvc</servlet-name>
