angular – 辅助路由仅适用于根组件吗？

这是我的路由器设置

export const routes: RouterConfig = [
    { path: 'test1',component: Test1Component },{ path: 'test2',component: Test2Component,outlet: 'aux'},{ path: 'shell',component: ShellComponent,children: [
        { path: 'department/:id',component: DepartmentDetailComponent },{ path: 'test3',component: Test3Component,outlet: 'aux2' }         ] }
];

如果我导航到

http://localhost:3000/shell/department/1(aux:test2)

然后输出是预期的,也就是说,Test2Component在ShellComponent和DepartmentDetailComponent中呈现在AppComponent中：

主要插座显示为蓝色,辅助插座为红色.

但是,如果我尝试导航到

http://localhost:3000/shell/department/1(aux2:test3)

我收到一条错误消息：

platform-browser.umd.js:1900 EXCEPTION: Error: Uncaught (in promise): Error: Cannot match any routes: ‘test3’

路由器插座如下：

app.component.ts(aux：test2)

<div class="app">
  <h1>App</h1>
  <div class="primary-outlet">
    <router-outlet></router-outlet>
  </div>
  <div class="aux-outlet">
    <router-outlet name="aux"></router-outlet>
  </div>
</div>

shell.component.ts(aux2：test3)

<div class="component">
  <h1>Shell</h1>
  <div class="primary-outlet">
    <router-outlet></router-outlet>
  </div>
  <div class="aux-outlet">
    <router-outlet name="aux2"></router-outlet>
  </div>
</div>

我错过了什么？

编辑：按照Arpit Agarwal的建议,导航到

http://localhost:3000/shell/(department/1(aux2:test3))

诀窍：

但是,请在页面加载后查看URL.如果我现在按F5,我会回到原点：

platform-browser.umd.js:1900 EXCEPTION: Error: Uncaught (in promise): Error: Cannot match any routes: ‘shell’
