webpack 能实现 angular-router 懒加载吗？

webpack打包了一个主js 然后打包成2个单独的js 但是路由变化的时候 没有加载这个路由的js
求指教？

#core.router.js
import LoginRouter from 'bundle?lazy!../states/login/login.route'
import IndexRouter from 'bundle?lazy!../states/index/index.route'

function CoreRouter($routeProvider,$locationProvider) {

    $routeProvider
        .when('/',IndexRouter)
        .when('/login',LoginRouter)
        .otherwise({redirectTo: '/'});
}

CoreRouter.$inject = ['$routeProvider','$locationProvider'];

export default CoreRouter;

下面是核心加载模块

#code.module.js
import $ from 'jquery'
import 'angular-animate'
import 'angular-route';
import 'angular-resource'
import 'angular-cookies'
import '../../lib/toaster/toaster.min'


import '../../service/service.module'
import '../..//components/components.module'
import '../..//filter/filter.module'

import '../../service/ApiConfig'
import '../../components/loading/http-loading';


import LoginModule from '../states/login/login.module'
import IndexModule from '../states/index/index.module'

//router核心模块最后加载
import CoreRouter from './core.router' //加载上面的核心路由模块

var CoreModule = angular.module('cm.bg',[
    'ngRoute',
    'ngCookies',
    'ngResource',
    'ngAnimate',
    'cm.filter',
    'cm.components',
    'cm.service',
    'toaster',

    LoginModule.name,IndexModule.name,
])
    .config(CoreRouter)
    .run(['$rootScope',
    function($rootScope){
    
    }]);


export default CoreModule

使用 ocLazyLoad 实现懒加载
