在哪里声明 Angular catch all (Not found) 路由

Where to declare Angular catch all (Not found) route

我有一个主 app.routing.module.ts 是这样的:

 const routes: Routes = [
  { path: 'home',  component: HomeComponent },
  { path: 'login', component: LoginComponent },
  { path: '', redirectTo: '/home', pathMatch: 'full' }
];

@NgModule({
  imports: [
    RouterModule.forRoot(routes),
  ],
  exports: [ RouterModule ]
})
export class AppRoutingModule {}

然后是几个子路由模块:

const routes: Routes = [
    { path: 'AbcRoute1', component: AbcRoute1Component },
    { path: 'AbcRoute2', component: AbcRoute2Component }
];

@NgModule({
    imports: [ RouterModule.forChild(routes) ],
    exports: [ RouterModule ]
})
export class AbcRoutingModule {}

const routes: Routes = [
    { path: 'DefRoute1', component: DefRoute1Component },
    { path: 'DefRoute2', component: DefRoute2Component }
];

@NgModule({
    imports: [ RouterModule.forChild(routes) ],
    exports: [ RouterModule ]
})
export class DefRoutingModule {}

我将此称为包罗万象的路线:

{ path: '**', redirectTo: '/home', pathMatch: 'full' }

如果我把它放在 AppRoutingModule 中,那么如果它不匹配 AppRoutingModule 中定义的任何路由,它就会启动。例如,我无法转到 DefRoutingModule

中定义的 https://myapp/DefRoute1

如果我把它放在 AbcRoutingModule 中,那么所有本地路由都可以工作,但 DefRoutingModule 中的内容不起作用。

我应该把它放在哪里,以便它只在我的所有路由模块都无法匹配 url 时才会匹配?

确保 AppRoutingModule(根路由模块)在模块导入中最后声明。然后在那里声明捕获所有通配符。文档 link:https://angular.io/guide/router#routing-module-order

@NgModule({
  declarations: [
    //...
  ],
  imports: [
    BrowserModule,
    FormsModule,
    ReactiveFormsModule,    
    HttpClientModule,
    // all other modules including any child routing modules

    // Last module
    AppRoutingModule
  ],
  providers: [
    //..
  ],
  bootstrap: [
    //..
  ]
})
export class AppModule { }
