Angular2路由器：如何使用自己的路由规则正确加载子模块

以下是我的Angular2应用程序结构：

这是我的部分代码。以下是Angular2应用程序的主

模块

，它导入路由规则和子模块（

EdgeModule

），并使用与某些页面相关的一些组件

应用程序模块.ts

@NgModule({
    declarations: [
        AppComponent,
        PageNotFoundComponent,
        LoginComponent
    ],
    imports: [
        ...
        appRouting,
        EdgeModule
    ],
    providers: [
        appRoutingProviders,
        LoginService
    ],
    bootstrap: [AppComponent]
})

export class AppModule {
}

const appRoutes: Routes = [
    { path: 'login', component: LoginComponent },
    { path: '**', component: PageNotFoundComponent }
];

export const appRoutingProviders: any[] = [];

export const appRouting = RouterModule.forRoot(appRoutes, { useHash: true });

@NgModule({
    declarations: [
        EdgeComponent,
        SidebarComponent,
        TopbarComponent
    ],
    imports: [
        ...
        edgeRouting,
        FirstSectionModule,
        SecondSectionModule
    ],
    providers: [
        AuthGuard
    ]
})

export class EdgeModule {
}

Paths['edgePaths'] = {
    firstSection: 'firstSection',
    secondSection: 'secondSection'
};

const appRoutes: Routes = [
    { path: '', component: EdgeComponent,
        canActivate: [AuthGuard],
        children: [
            { path: Paths.edgePaths.firstSection, loadChildren: '../somepath/first-section.module#FirstModule' },
            { path: Paths.edgePaths.secondSection, loadChildren: '../someotherpath/second-section.module#SecondModule' },
            { path: '', redirectTo: edgePaths.dashboard, pathMatch: 'full' }
        ]
    }
];

export const edgeRouting = RouterModule.forChild(appRoutes);

@NgModule({
    declarations: [
        FirstSectionComponent,
        SomeComponent
    ],
    imports: [
        ...
        firstSectionRouting
    ],
    providers: [
        AuthGuard,
    ]
})

export class FirstSectionModule {
}

Paths['firstSectionPaths'] = {
    someSubPage: 'some-sub-page',
    someOtherSubPage: 'some-other-sub-page'
};

const appRoutes: Routes = [
    {
        path: '',
        children: [
            { path: Paths.firstSectionPaths.someSubPage, component: someSubPageComponent},
            { path: Paths.firstSectionPaths.someOtherSubPage, component: someOtherSubPageComponent},
            { path: '', component: AnagraficheComponent }
        ]
    }
];

export const firstSectionRouting = RouterModule.forChild(appRoutes);

以下是主模块的路由规则。它有登录页面和未找到页面的路径

app.routing.ts

@NgModule({
    declarations: [
        AppComponent,
        PageNotFoundComponent,
        LoginComponent
    ],
    imports: [
        ...
        appRouting,
        EdgeModule
    ],
    providers: [
        appRoutingProviders,
        LoginService
    ],
    bootstrap: [AppComponent]
})

export class AppModule {
}

const appRoutes: Routes = [
    { path: 'login', component: LoginComponent },
    { path: '**', component: PageNotFoundComponent }
];

export const appRoutingProviders: any[] = [];

export const appRouting = RouterModule.forRoot(appRoutes, { useHash: true });

@NgModule({
    declarations: [
        EdgeComponent,
        SidebarComponent,
        TopbarComponent
    ],
    imports: [
        ...
        edgeRouting,
        FirstSectionModule,
        SecondSectionModule
    ],
    providers: [
        AuthGuard
    ]
})

export class EdgeModule {
}

Paths['edgePaths'] = {
    firstSection: 'firstSection',
    secondSection: 'secondSection'
};

const appRoutes: Routes = [
    { path: '', component: EdgeComponent,
        canActivate: [AuthGuard],
        children: [
            { path: Paths.edgePaths.firstSection, loadChildren: '../somepath/first-section.module#FirstModule' },
            { path: Paths.edgePaths.secondSection, loadChildren: '../someotherpath/second-section.module#SecondModule' },
            { path: '', redirectTo: edgePaths.dashboard, pathMatch: 'full' }
        ]
    }
];

export const edgeRouting = RouterModule.forChild(appRoutes);

@NgModule({
    declarations: [
        FirstSectionComponent,
        SomeComponent
    ],
    imports: [
        ...
        firstSectionRouting
    ],
    providers: [
        AuthGuard,
    ]
})

export class FirstSectionModule {
}

Paths['firstSectionPaths'] = {
    someSubPage: 'some-sub-page',
    someOtherSubPage: 'some-other-sub-page'
};

const appRoutes: Routes = [
    {
        path: '',
        children: [
            { path: Paths.firstSectionPaths.someSubPage, component: someSubPageComponent},
            { path: Paths.firstSectionPaths.someOtherSubPage, component: someOtherSubPageComponent},
            { path: '', component: AnagraficheComponent }
        ]
    }
];

export const firstSectionRouting = RouterModule.forChild(appRoutes);

这里是

EdgeModule

，它声明它使用的组件并导入它自己的路由规则和2个子模块（

FirstSectionModule

和

SecondSectionModule

）

edge.module.ts

@NgModule({
    declarations: [
        AppComponent,
        PageNotFoundComponent,
        LoginComponent
    ],
    imports: [
        ...
        appRouting,
        EdgeModule
    ],
    providers: [
        appRoutingProviders,
        LoginService
    ],
    bootstrap: [AppComponent]
})

export class AppModule {
}

const appRoutes: Routes = [
    { path: 'login', component: LoginComponent },
    { path: '**', component: PageNotFoundComponent }
];

export const appRoutingProviders: any[] = [];

export const appRouting = RouterModule.forRoot(appRoutes, { useHash: true });

@NgModule({
    declarations: [
        EdgeComponent,
        SidebarComponent,
        TopbarComponent
    ],
    imports: [
        ...
        edgeRouting,
        FirstSectionModule,
        SecondSectionModule
    ],
    providers: [
        AuthGuard
    ]
})

export class EdgeModule {
}

Paths['edgePaths'] = {
    firstSection: 'firstSection',
    secondSection: 'secondSection'
};

const appRoutes: Routes = [
    { path: '', component: EdgeComponent,
        canActivate: [AuthGuard],
        children: [
            { path: Paths.edgePaths.firstSection, loadChildren: '../somepath/first-section.module#FirstModule' },
            { path: Paths.edgePaths.secondSection, loadChildren: '../someotherpath/second-section.module#SecondModule' },
            { path: '', redirectTo: edgePaths.dashboard, pathMatch: 'full' }
        ]
    }
];

export const edgeRouting = RouterModule.forChild(appRoutes);

@NgModule({
    declarations: [
        FirstSectionComponent,
        SomeComponent
    ],
    imports: [
        ...
        firstSectionRouting
    ],
    providers: [
        AuthGuard,
    ]
})

export class FirstSectionModule {
}

Paths['firstSectionPaths'] = {
    someSubPage: 'some-sub-page',
    someOtherSubPage: 'some-other-sub-page'
};

const appRoutes: Routes = [
    {
        path: '',
        children: [
            { path: Paths.firstSectionPaths.someSubPage, component: someSubPageComponent},
            { path: Paths.firstSectionPaths.someOtherSubPage, component: someOtherSubPageComponent},
            { path: '', component: AnagraficheComponent }
        ]
    }
];

export const firstSectionRouting = RouterModule.forChild(appRoutes);

下面是加载topbar和sidebar组件的模块的路由规则

edge.routing.ts

@NgModule({
    declarations: [
        AppComponent,
        PageNotFoundComponent,
        LoginComponent
    ],
    imports: [
        ...
        appRouting,
        EdgeModule
    ],
    providers: [
        appRoutingProviders,
        LoginService
    ],
    bootstrap: [AppComponent]
})

export class AppModule {
}

const appRoutes: Routes = [
    { path: 'login', component: LoginComponent },
    { path: '**', component: PageNotFoundComponent }
];

export const appRoutingProviders: any[] = [];

export const appRouting = RouterModule.forRoot(appRoutes, { useHash: true });

@NgModule({
    declarations: [
        EdgeComponent,
        SidebarComponent,
        TopbarComponent
    ],
    imports: [
        ...
        edgeRouting,
        FirstSectionModule,
        SecondSectionModule
    ],
    providers: [
        AuthGuard
    ]
})

export class EdgeModule {
}

Paths['edgePaths'] = {
    firstSection: 'firstSection',
    secondSection: 'secondSection'
};

const appRoutes: Routes = [
    { path: '', component: EdgeComponent,
        canActivate: [AuthGuard],
        children: [
            { path: Paths.edgePaths.firstSection, loadChildren: '../somepath/first-section.module#FirstModule' },
            { path: Paths.edgePaths.secondSection, loadChildren: '../someotherpath/second-section.module#SecondModule' },
            { path: '', redirectTo: edgePaths.dashboard, pathMatch: 'full' }
        ]
    }
];

export const edgeRouting = RouterModule.forChild(appRoutes);

@NgModule({
    declarations: [
        FirstSectionComponent,
        SomeComponent
    ],
    imports: [
        ...
        firstSectionRouting
    ],
    providers: [
        AuthGuard,
    ]
})

export class FirstSectionModule {
}

Paths['firstSectionPaths'] = {
    someSubPage: 'some-sub-page',
    someOtherSubPage: 'some-other-sub-page'
};

const appRoutes: Routes = [
    {
        path: '',
        children: [
            { path: Paths.firstSectionPaths.someSubPage, component: someSubPageComponent},
            { path: Paths.firstSectionPaths.someOtherSubPage, component: someOtherSubPageComponent},
            { path: '', component: AnagraficheComponent }
        ]
    }
];

export const firstSectionRouting = RouterModule.forChild(appRoutes);

最后，这是两个子模块之一，它有自己的组件并导入路由规则

第一节.module.ts

@NgModule({
    declarations: [
        AppComponent,
        PageNotFoundComponent,
        LoginComponent
    ],
    imports: [
        ...
        appRouting,
        EdgeModule
    ],
    providers: [
        appRoutingProviders,
        LoginService
    ],
    bootstrap: [AppComponent]
})

export class AppModule {
}

const appRoutes: Routes = [
    { path: 'login', component: LoginComponent },
    { path: '**', component: PageNotFoundComponent }
];

export const appRoutingProviders: any[] = [];

export const appRouting = RouterModule.forRoot(appRoutes, { useHash: true });

@NgModule({
    declarations: [
        EdgeComponent,
        SidebarComponent,
        TopbarComponent
    ],
    imports: [
        ...
        edgeRouting,
        FirstSectionModule,
        SecondSectionModule
    ],
    providers: [
        AuthGuard
    ]
})

export class EdgeModule {
}

Paths['edgePaths'] = {
    firstSection: 'firstSection',
    secondSection: 'secondSection'
};

const appRoutes: Routes = [
    { path: '', component: EdgeComponent,
        canActivate: [AuthGuard],
        children: [
            { path: Paths.edgePaths.firstSection, loadChildren: '../somepath/first-section.module#FirstModule' },
            { path: Paths.edgePaths.secondSection, loadChildren: '../someotherpath/second-section.module#SecondModule' },
            { path: '', redirectTo: edgePaths.dashboard, pathMatch: 'full' }
        ]
    }
];

export const edgeRouting = RouterModule.forChild(appRoutes);

@NgModule({
    declarations: [
        FirstSectionComponent,
        SomeComponent
    ],
    imports: [
        ...
        firstSectionRouting
    ],
    providers: [
        AuthGuard,
    ]
})

export class FirstSectionModule {
}

Paths['firstSectionPaths'] = {
    someSubPage: 'some-sub-page',
    someOtherSubPage: 'some-other-sub-page'
};

const appRoutes: Routes = [
    {
        path: '',
        children: [
            { path: Paths.firstSectionPaths.someSubPage, component: someSubPageComponent},
            { path: Paths.firstSectionPaths.someOtherSubPage, component: someOtherSubPageComponent},
            { path: '', component: AnagraficheComponent }
        ]
    }
];

export const firstSectionRouting = RouterModule.forChild(appRoutes);

这些是

FirstSectionModule

第一节.routing.ts

@NgModule({
    declarations: [
        AppComponent,
        PageNotFoundComponent,
        LoginComponent
    ],
    imports: [
        ...
        appRouting,
        EdgeModule
    ],
    providers: [
        appRoutingProviders,
        LoginService
    ],
    bootstrap: [AppComponent]
})

export class AppModule {
}

const appRoutes: Routes = [
    { path: 'login', component: LoginComponent },
    { path: '**', component: PageNotFoundComponent }
];

export const appRoutingProviders: any[] = [];

export const appRouting = RouterModule.forRoot(appRoutes, { useHash: true });

@NgModule({
    declarations: [
        EdgeComponent,
        SidebarComponent,
        TopbarComponent
    ],
    imports: [
        ...
        edgeRouting,
        FirstSectionModule,
        SecondSectionModule
    ],
    providers: [
        AuthGuard
    ]
})

export class EdgeModule {
}

Paths['edgePaths'] = {
    firstSection: 'firstSection',
    secondSection: 'secondSection'
};

const appRoutes: Routes = [
    { path: '', component: EdgeComponent,
        canActivate: [AuthGuard],
        children: [
            { path: Paths.edgePaths.firstSection, loadChildren: '../somepath/first-section.module#FirstModule' },
            { path: Paths.edgePaths.secondSection, loadChildren: '../someotherpath/second-section.module#SecondModule' },
            { path: '', redirectTo: edgePaths.dashboard, pathMatch: 'full' }
        ]
    }
];

export const edgeRouting = RouterModule.forChild(appRoutes);

@NgModule({
    declarations: [
        FirstSectionComponent,
        SomeComponent
    ],
    imports: [
        ...
        firstSectionRouting
    ],
    providers: [
        AuthGuard,
    ]
})

export class FirstSectionModule {
}

Paths['firstSectionPaths'] = {
    someSubPage: 'some-sub-page',
    someOtherSubPage: 'some-other-sub-page'
};

const appRoutes: Routes = [
    {
        path: '',
        children: [
            { path: Paths.firstSectionPaths.someSubPage, component: someSubPageComponent},
            { path: Paths.firstSectionPaths.someOtherSubPage, component: someOtherSubPageComponent},
            { path: '', component: AnagraficheComponent }
        ]
    }
];

export const firstSectionRouting = RouterModule.forChild(appRoutes);

对于

second section.module.ts

和

second section.routing.ts

文件，情况几乎相同

当我运行应用程序时，首先加载的是与

FirstSectionComponent

相关的页面，没有侧栏和顶栏

---

你能告诉我我的代码有什么问题吗？控制台中没有错误。

不确定我是否正确地解决了问题，但这里有一个小代码段，我用来动态生成路由：

app.component.ts：

constructor(private _router: Router) {
}

ngOnInit() {
     ...
     this._router.config[0].children = myService.getRoutes(); 
     this._router.resetConfig(this._router.config);
     console.debug('Routes:', this._router.config);
     ...
}

---

这不是OOTB解决方案，但您可以获取有关当前路由的信息。

您可以使用

loadChildren

进行尝试，其中

homeModule

，

productModule

，

aboutModule

有自己的路由规则

const routes: Routes = [
    { path: 'home', loadChildren: 'app/areas/home/home.module#homeModule' },
    { path: 'product', loadChildren: 'app/areas/product/product.module#ProductModule' },
    { path: 'drawing', loadChildren: 'app/areas/about/about.module#AboutModule' }
];

export const appRouting = RouterModule.forRoot(routes);

回家的路线规则是这样的

export const RouteConfig: Routes = [
    {
        path: '',
        component: HomeComponent,
        canActivate: [AuthGuard],
        children: [
            { path: '', component: HomePage },
            { path: 'test/:id', component: Testinfo},
            { path: 'test2/:id', component: Testinfo1},
            { path: 'test3/:id', component: Testinfo2}
        ]
    }
];

这也称为延迟加载模块

{ path: 'lazy', loadChildren: 'lazy/lazy.module#LazyModule' }

这里有几件重要的事情需要注意： 我们使用属性

loadChildren

而不是组件。 我们传递一个字符串而不是一个符号，以避免急切地加载模块。 我们不仅定义了模块的路径，还定义了类的名称。

LazyModule

没有什么特别之处，只是它有自己的路由和一个名为

LazyComponent

的组件

查看与此相关的精彩教程：

---

这是一个依赖注入问题。 我们不需要在edgeModule中插入FirstSectionModule和SecondSectionModule&关于可以在FirstSectionModule和SecondSectionModule内部使用的路由。

---

因此，只需将其从edgeModule中删除即可。

在你的app.routing.ts中，只有2条路线，没有路线可导航到主要部分（如图所示）。需要有一个具有loadchildren属性的路由条目，这样它将加载主区段的模块

routes: Routes = [...
{ 
path: 'main', loadChildren: '<file path>/<Edge module file name>#EdgeModule' 
}
...];

routes:routes=[。。。
{ 
路径：“main”，loadChildren:“/#EdgeModule”
}
...];

---

这将加载EdgeModule中的其余模块、组件路由和所有内容。

尝试从

EdgeModule

中删除

FirstSectionModule

和

SecondSectionModule

，执行此操作并更改

edge.routing.ts中的路径！非常感谢。无论如何，我不得不在模块的懒散加载中加入运行时路径以使应用程序正常工作，这很奇怪……我试图创建一个Plunker，但我无法重现我的情况。你能帮助我吗？我没有发现类似于“loadChildren”的东西可以通知框架在特定点“插入”子模块路由配置…您能更具体一点吗？好的，请告诉我如何在应用程序启动后动态生成路由。谢谢您的回答，不管怎样，延迟加载ans SystemJS的问题在于，当您为生产构建应用程序时，当您获得一个缩小的JS文件作为Gulp构建任务的输出时，这些路径不存在。您是否尝试添加索引。htmlI意味着在缩小的JS文件中，我没有对路径的引用，例如
/lazy/lazy.module
