typescript – Angular2 rc1,新路由器和传递数据

一些组件

import {Component,Injector} from 'angular2/core';
import {IDataServiceSome} from './IDataServiceSome';
import {RouteData} from 'angular2/router';

@Component({
    selector: 'Some',templateUrl: './Some.html'
})
export class Some {
    Model;
    DataService: IDataServiceVendor;

    constructor(routeData: RouteData,injector: Injector) {
        var dataServiceToken = routeData.get('DataServiceToken');
        this.DataService = injector.get(dataServiceToken);
        this.Model = DataService.getSomeModel();
    }
}

IDataServiceSome

export interface IDataServiceSome {
    getSomeModel(): Object;
}

例如Comp1但有Comp2,Comp3等……

import {Component} from 'angular2/core';
import {RouteConfigs,Router,ROUTER_DIRECTIVES} from 'angular2/router';

import {DataServiceSome1} from './IDataServiceSome1';

@RouteConfigs([
    { path: '/Some',name: 'Some',component: Some,data: { DataServiceToken: DataServiceSome1 } }])
@Component({
    directives: [ROUTER_DIRECTIVES],providers: [DataServiceSome1],selector: 'Comp1',template:
    `<div>
        <router-outlet></router-outlet>
        <h1>Comp1 routed to Some</h1>
    </div>`
})
export class Comp1{

}

您可能已经猜到,有许多数据服务实现了IDataServiceSome和许多路由到Some的组件.选择使用哪种数据服务来自使用注入器已知的数据令牌路由到某个组件的任何组件.使用rc1版本和新路由器时,不推荐使用RouteData或删除RouteData,但是这个方案如何实现呢？
