如何在角度2中默认加载子路径

在应用程序的开始我想加载子路由.

现在是URLcome但是相应的组件没有加载到该部分,但是当再次点击实际的URL时.

像route configure一样

  const appRoutes: Routes = [
        { path: 'a', component: AComponent,
         children:[
                   { path:'x',component:AXcomponent }
                   ]
        },
        { path: 'b', component: bComponent, }
]

现在我想加载路径a/x如何在页面开头加载？

添加空路径路径作为自动重定向

const appRoutes: Routes = [
    {
        path:'',
        redirectTo: 'a',
        pathMatch: 'full' 
    },
    {
        path: 'a',
        component: AComponent,
        children:[
            {
                path:'',
                redirectTo: 'x',
                pathMatch: 'full' 
            },
            {
                path:'x',
                component: AXcomponent 
            }
        ]
    },
    { 
        path: 'b',
        component: bComponent
    }
];
