使用webpack在Angular2中包含jQuery并从组件访问它

因此我通过npm安装了jQuery.

的package.json

"dependencies": {
    // ...
    "jquery": "2.1.4",// ...
  },

文件和文件夹已正确安装.

我现在在vendor.ts中定位这些文件以获取webpack以查找并包含它们：

import 'jquery';
import 'bootstrap/dist/js/bootstrap.js';
import '../../bower_components/signalr/jquery.signalR';

并且webpack获取这些文件并将它们连接起来.我可以在我的vendor.js中看到这个. jQuery出现在那里.还有jquery signalR-File.

我的webpack.config：

var webpack = require("webpack");
var HtmlWebpackPlugin = require('html-webpack-plugin');

module.exports = {
    entry: {
        "vendor": "./wwwroot/app/vendor","polyfills": "./wwwroot/app/polyfills","app": "./wwwroot/app/boot"
    },output: {
        path: __dirname,filename: "[name]-[hash:8].bundle.js"
    },resolve: {
        extensions: ['','.ts','.js','.html']
    },devtool: 'source-map',module: {
        loaders: [
            {
                test: /.ts/,loaders: ['ts-loader'],exclude: /node_modules/
            },{
                test: /.html$/,loader: 'html'
            },{
                test: /.css$/,loader: 'raw'
            }
        ]
    },plugins: [
         new webpack.ProvidePlugin({
            jQuery: 'jquery',$: 'jquery',jquery: 'jquery'
        }),//new webpack.optimize.DedupePlugin(),new webpack.optimize.CommonsChunkPlugin({
            name: ["app","vendor","polyfills"]
        })
    ]
}

在我的索引中加载如下：

<script src="js/polyfills-2eba52f6.bundle.js"></script>
<script src="js/vendor-2eba52f6.bundle.js"></script>
<script src="js/app-2eba52f6.bundle.js"></script>

但是当我尝试在我的angular2组件中使用它时：

// ...

declare var jQuery:any;
declare var $:any;

@Injectable()
export class MySignalRService {

    private connection;

    constructor() {

        this.connection = $.hubConnection(CONFIGURATION.baseUrls.server + 'signalr/');
        jQuery.hubConnection(CONFIGURATION.baseUrls.server + 'signalr/');

        // ...
    }

    //...

我总是得到消息

$.hubConnection is not a function

Error: jQuery was not found. Please ensure jQuery is referenced before
the SignalR client JavaScript file.

安慰“$”和“jquery”是未定义的.

如何访问webpack中的singalr-Function？
