创建模块，用到了共享模块PostSharedModule，共享模块里面包含了2个公用的模块：文章管理模块和评论管理模块

1,创建一个模块testmodule.module.ts

import { CommonModule } from '@angular/common';
import { NgModule } from '@angular/core';
import { RouterModule } from "@angular/router";
import { PostSharedModule } from '../shared/post.module';
import { testModule } from './testmodule.routes';
import { TestMainComponent } from './test-main/test-main.component';
import { PostTableService } from '../manage/post-table/services/post-table.service';
@NgModule({
  declarations: [
    TestMainComponent
  ],imports: [
	  CommonModule,PostSharedModule,RouterModule.forChild(testModule)
  ],exports:[
    TestMainComponent
  ],providers: [
    PostTableService
  ]
})
export class TestModule { }

import { TestMainComponent } from './test-main/test-main.component';
import { PostTableComponent } from '../manage/post-table/post-table.component';
import { CommentTableComponent } from '../manage/comment-table/comment-table.component';
export const testModule = [
    {
        path:'',component:TestMainComponent,children: [
            { path: '',redirectTo:'posttable/page/1',pathMatch:'full'},{ path: 'posttable/page/:page',component: PostTableComponent },{ path: 'commenttable/page/:page',component: CommentTableComponent },{ path: '**',redirectTo:'posttable/page/1' }
        ]
    }
];

<a routerLink="posttable/page/1" class="list-group-item"><span class="badge">10000</span>文章管理</a>
        <a routerLink="commenttable/page/1" class="list-group-item"><span class="badge">1000000</span>评论管理</a>

import { NgModule } from '@angular/core';
import { ModalModule } from 'ng2-bootstrap';
import { PaginationModule } from 'ng2-bootstrap';
import { SharedModule } from './shared.module';
import { CommentTableComponent } from '../manage/comment-table/comment-table.component';
import { PostTableComponent } from '../manage/post-table/post-table.component';
@NgModule({
  imports:[ 
    SharedModule,ModalModule.forRoot(),PaginationModule.forRoot()
  ],declarations:[ 
  	CommentTableComponent,PostTableComponent
  ],exports:[ 
    ModalModule,PaginationModule,CommentTableComponent,PostTableComponent
  ]
})
export class PostSharedModule {
  
}
