关于在reactjs项目中如何用webpack配置组件按需加载

import {Button} from 'antd'

import Button from 'antd/lib/button';
import 'antd/lib/button/style'; // 或者 antd/lib/button/style/css 加载 css 文件

{
        test: /\.js|jsx$/,
        exclude: /(node_modules|bower_components)/,
        loader: 'babel-loader',
        query: {
          presets: ['es2015','react'],
          plugins: [["import", { libraryName: "antd", style: "css"}]]
        }
      },
