我有一些问题的路由未找到的页面。我使用的是Angular（类型脚本）。在我的应用程序中，我有4个主要的路由：应用程序路由、登录路由、用户路由和管理员路由。我创建了NotFoundComponent，如果添加以下语法：

{ path: '404', component: NotfoundComponent},
{ path: '**', redirectTo:'/404'}

如果我将其添加到UserRouting，当我以admin身份登录时，它会转到404;如果我将其添加到AdminRouting，当我以用户身份登录时，它会转到404;如果我将其添加到AppRouting，当我以用户和管理员身份登录时，它会转到404;我应该做些什么才能让事情正常进行？以下是我的路由代码：
用户路由：

const routes: Routes = [
  { path: 'user-dashboard', component: UserLayoutComponent, 
  canActivate:[AuthGuard],
  children:[
    { path: '', component: UserDashboardComponent},
    { path: 'profilo-user', component: ProfilouserComponent},
    { path: 'preferiti', component: CarrelloComponent},
    { path: 'contatti', component: ContattiComponent},
    { path: 'prodotti-negozio'/*/:id:nome*/, component: ProdottiNegozioComponent}
  ]},
];

管理路由：

const routes: Routes = [
  { path: 'admin-dashboard', component: AdminLayoutComponent, 
  canActivate:[AuthGuard], canActivateChild:[AuthGuard], children:[
    { path: '', component: AdminDashboardComponent},
    { path: 'profilo-admin', component: ProfiloadminComponent},
    { path: 'users', component: UsersComponent},
    { path: 'work-in-progress', component: WorkInProgressComponent}
  ]},
];

AppRouting：

const routes: Routes = [
  { path: '', redirectTo:'/login', pathMatch: 'full' },
  { path: '404', component: NotfoundComponent},
  { path: '**', redirectTo:'/404'}
];

登录路由：

const routes: Routes = [
  { path:'login', component: LoginComponent }
];

我该怎么做才能让它正常工作？
