Angular2更新为rc5和@ angular / router-原始例外：没有路由器的提供程序

Question

I have updated our project from rc4 -> rc5. That seems to work fine. At the same time as doing this, i have also updated our code from using the @angular/router-deprecated to @angular/router .

My application is made up of 2 sections, public and protected (public is for all users, protected is just for admins). But currently i just want to get 1 route working, then i can fix the other pages.

As i said i have updated all the code, which i believe is correct and the pages load until i add this to my page [routerLink]="['Home']"

If i add this, then i get the exception

ORIGINAL EXCEPTION: No provider for Router!

If i comment this line out again, the pages all load fine.

Here is some of my code

app.module.ts

import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule }   from '@angular/forms';
import { RouterModule } from '@angular/router';
import { HttpModule } from '@angular/http';

import { AppRoutes } from './app.routes';
import { AppComponent }  from './app.component';
import { PublicComponent } from './public.component';
//import { ProtectedComponent } from './protected.component';

// cms
import { HomeComponent } from './cms/home.component';

@NgModule({
    imports: [
        BrowserModule,
        FormsModule,
        HttpModule,
        RouterModule.forRoot(AppRoutes)
    ],
    declarations: [
        AppComponent,
        PublicComponent,
        HomeComponent
    ],
    bootstrap: [ AppComponent ]
})

export class AppModule { }

app.routes.ts

import { PublicComponent } from './public.component';
import { ProtectedComponent } from './protected.component';

// public
import { HomeComponent } from './cms/home.component';


export const AppRoutes = [
    {
        path: '',
        component: PublicComponent,
        children: [
            {
                path: '',
                redirectTo: 'home',
                pathMatch: 'full'
            },
            {
                path: 'home',
                component: HomeComponent
            },
        ]
    },
    // {
    //     path: 'admin/...',
    //     component: ProtectedComponent
    // }
];

app.component.ts

import { Component, ViewContainerRef } from '@angular/core';
import { ROUTER_DIRECTIVES } from '@angular/router'

@Component({
    selector: 'app-root',
    template: '<router-outlet></router-outlet>',
    directives: [ ROUTER_DIRECTIVES ]
})

export class AppComponent {
    viewContainerRef: ViewContainerRef;

    constructor(viewContainerRef: ViewContainerRef) {
        this.viewContainerRef = viewContainerRef;
    }
}

main.ts

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app.module';

platformBrowserDynamic().bootstrapModule(AppModule);

public.component.ts

import { Component, OnInit } from '@angular/core';
import { Router, ROUTER_DIRECTIVES } from '@angular/router';
import { CmsService } from './cms/cms.service';
import { ModuleService } from './module/module.service';
import { MenuItem } from './cms/models/menu-item';
import { Settings } from './cms/models/settings';
import { CollapseDirective } from 'ng2-bootstrap/components/collapse';
import { OffClickDirective } from './shared/offclick.directive';

@Component({
    selector: 'public',
    templateUrl: 'app/public.component.html',
    directives: [ ROUTER_DIRECTIVES, CollapseDirective, OffClickDirective ],
    providers: [ CmsService, ModuleService ]
})

export class PublicComponent {
    menu: MenuItem[];
    settings: Settings;
    isCollapsed: boolean = true;

    constructor(
        private cmsService: CmsService,
        private router: Router) {
    }
}

public.component.html

<div class="navbar navbar-dark bg-inverse navbar-fixed-top" role="navigation">
    <div class="container">
        <a class="navbar-brand" [routerLink]="['Home']">
            <span class="fa fa-home fa-2x" aria-hidden="true"></span>
            <span class="sr-only">Home</span>
        </a>
    </div>
</div>

I have tried adding Router to the providers section in public.component.ts but then i get another exception as below.

Error: Can't resolve all parameters for Router: (?, ?, ?, ?, ?, ?, ?, ?)

I have obviously missed something, but dont know what. Any help would be much appreciated.

Just encase it helps, here are the angular references in my package.json file as well

"dependencies": {
    "@angular/common": "^2.0.0-rc.5",
    "@angular/compiler": "^2.0.0-rc.5",
    "@angular/core": "^2.0.0-rc.5",
    "@angular/forms": "^0.3.0",
    "@angular/http": "^2.0.0-rc.5",
    "@angular/platform-browser": "^2.0.0-rc.5",
    "@angular/platform-browser-dynamic": "^2.0.0-rc.5",
    "@angular/router": "^3.0.0-rc.1",
    "@angular/router-deprecated": "2.0.0-rc.2",
    "@angular/upgrade": "^2.0.0-rc.3"
}

Answer 1

1. Delete routermodule from app.module.ts

2. Adjust app.module.ts

    ... import { routing, appRoutingProviders } from './app.routing'; ... @NgModule({ imports: [ ... routing, ... ], ... providers: [ ... appRoutingProviders, ... ], bootstrap: [AppComponent], }) export class AppModule { } 

3. Adjust app.routing.ts:

    import { Routes, RouterModule } from '@angular/router'; import { DashboardComponent } from './dashboard/dashboard.component'; ... import { Http, HTTP_PROVIDERS } from '@angular/http'; const appRoutes: Routes = [ { path: '', redirectTo: '/dashboard', pathMatch: 'full'}, { path: 'dashboard', component: DashboardComponent, canActivate: [AuthGuard]}, ... { path: '**', redirectTo: 'dashboard', pathMatch: 'full'} ]; export const appRoutingProviders: any[] = [ ... Http, HTTP_PROVIDERS ]; export const routing = RouterModule.forRoot(appRoutes); 

4. Remove ROUTER_DIRECTIVES everywhere
