我收到错误,找不到原因.这是错误:

我使用的是Angular 2.0.0-alpha.30版本.当重定向到不同的路由,然后刷新浏览器,它显示无法GET /路由.

你能帮我弄清楚这个错误发生的原因吗？

如何在@Routes路径元数据集合中设置默认路由？如果使用@ angular/router-deprecated中的angular2路由器,则在@routeConfig对象中定义路由,该对象是路由对象的集合,但这些路由对象具有更多属性.例如,它们具有'name'和'useAsDefualt'属性,而从@ angular/router定义的路由则没有.我想用新路由器编写我的新应用程序,但是如何使用新路由器并设置默认路由？

这是我的主要app组件,它定义了我的路线:

import { Component } from '@angular/core';
import { DashboardComponent } from './dashboard/dashboard.component';
import { ConfigManagerComponent } from './configManager/configManager.component';
import { ApplicationMgmtComponent } from './applicationMgmt/applicationMgmt.component';
import { MergeComponent } from './merge/merge.component';

import { ROUTER_DIRECTIVES, Routes } from '@angular/router';


@Component({
    selector: 'app-container',
    templateUrl: 'app/app.component.html',
    directives: [ROUTER_DIRECTIVES]
})

@Routes([

        { path: '/Dashboard', component: DashboardComponent },
        { path: '/ConfigManager', component: ConfigManagerComponent },
        { path: '/Merge', component: MergeComponent },
        { path: '/ApplicationManagement', component: ApplicationMgmtComponent }
])

export class AppComponent { } …
