将数据绑定到角度2路由组件

Question

我现在有以下模板

<project-form [nextId]="projects.length" (newProject)="addProject($event)"></project-form>
<project-list [projects]="projects"></project-list>

在ProjectAppComponent中.

class ProjectAppComponent {
    projects: Project[] = [
        { id: 0, title: "Build the issue tracker" },
        { id: 1, title: "Basecamp" },
    ]

    addProject(project: Project) {
        this.projects.push(project);
    } 
}

ProjectAppComponent具有项目数组和将新项目推入其中的方法.我想创建子路由项目的形式和项目名单,所以我可以做的/projects/new,并/projects/show表现出任何形式或列表.我创建了这样的路线配置 -

@Component({
    template: `
        <div>
            <router-outlet></router-outlet>
        </div>
    `,
    directives: [ RouterOutlet ]
})
@RouteConfig([
    { path: '/list', name: 'ProjectList', component: ProjectListComponent, useAsDefault: true },
    { path: '/new', name: 'ProjectForm', component: ProjectFormComponent },
])
class ProjectAppComponent {
    projects: Project[] = [
        { id: 0, title: "Build the issue tracker" },
        { id: 1, title: "Basecamp" },
    ]

    addProject(project: Project) {
        this.projects.push(project);
    } 
}

对于ProjectAppComponent类本身.现在的问题是我不知道如何将项目数组([projects]="projects"在模板中)传递给ProjectListComponent,因为<project-list>选择器不再使用(必须使用<router-outlet>).ProjectListComponent依赖于@Input() project: Project渲染所有项目.我该如何解决这个问题？这是项目列表组件 -

@Component({
    selector: 'project-list',
    template: `
        <ul>
            <project-component *ngFor="#project of projects" [project]="project"></project-component>
        </ul>
    `,
    directives: [ProjectComponent]
})
class ProjectListComponent {
    @Input() projects: Project[];
}

你不能只使用一项服务吗？

import {Injectable} from 'angular2/core';
import {Project} from '...';


@Injectable()
export class ProjectService {
  public projects: Project[] = [
    { id: 0, title: "Build the issue tracker" },
    { id: 1, title: "Basecamp" },
  ];

  addProject(...args): number {
    return this.projects.push(new Project(...args));
  }
}
