其实多页面的根本就是 webpack多入口和HtmlWebpackPlugin的多页面输出

要生成的多页面配置(pageConfig.js)

module.exports=[
  {
    entry_name:"login",
    title:"爱问医生-登录"
  },
  {
    entry_name:"register",
    title:"爱问医生-注册"
  },
  {
    entry_name:"pw_retrieve",
    title:"爱问医生-找回密码"
  },
  {
    entry_name:"user_edit",
    title:"爱问医生-个人信息"
  }
];

生成多入口【build\webpack.base.conf.js】

var appPageArr = require("../src/pageConfig");
var configEntry = {};
appPageArr.forEach((page) => {
  configEntry[page.entry_name] =`./src/pages/${page.entry_name}.js`;
});

module.exports = {
  entry: configEntry,
  output: {
    path: config.build.assetsRoot,
    filename: "[name].js",
    publicPath: process.env.NODE_ENV === "production"
      ? config.build.assetsPublicPath
      : config.dev.assetsPublicPath
  },
  ...
}

开发服务器生成多页面

//多入口生成
var appPageArr = require("../src/pageConfig");

//生成多个html文件
var configHtmlWebpackPlugin = [];
appPageArr.forEach((page) => {
  configHtmlWebpackPlugin.push(new HtmlWebpackPlugin({
    chunks:["manifest", "vendor",page.entry_name],
    filename: page.entry_name+".html",
    title: page.title,
    template: "index.html",
    inject: true
  })
 );
});


//===========================
module.exports = merge(baseWebpackConfig, {
  module: {
    rules: utils.styleLoaders({ sourceMap: config.dev.cssSourceMap })
  },
  // cheap-module-eval-source-map is faster for development
  devtool: "#cheap-module-eval-source-map",
  plugins: [
    new webpack.DefinePlugin({
      "process.env": config.dev.env
    }),
    // https://github.com/glenjamin/webpack-hot-middleware#installation--usage
    new webpack.HotModuleReplacementPlugin(),
    new webpack.NoEmitOnErrorsPlugin(),
    // https://github.com/ampedandwired/html-webpack-plugin
    ...configHtmlWebpackPlugin,
    new FriendlyErrorsPlugin()
  ]
});

打包配置（打包成多个文件）

var appPageArr = require("../src/pageConfig");
var configHtmlWebpackPlugin = [];
appPageArr.forEach((page) => {
  configHtmlWebpackPlugin.push(new HtmlWebpackPlugin({
    chunks:["manifest", "vendor",page.entry_name],
    filename: page.entry_name+".html",
    template: "index.html",
    title: page.title,
    inject: true,
    minify: {
      removeComments: true,
      collapseWhitespace: true,
      removeAttributeQuotes: true
      // more options:
      // https://github.com/kangax/html-minifier#options-quick-reference
    },
    // necessary to consistently work with multiple chunks via CommonsChunkPlugin
    chunksSortMode: "dependency"
  })
 );
});


//接下来引用
var webpackConfig = merge(baseWebpackConfig, {
  module: {
    rules: utils.styleLoaders({
      sourceMap: config.build.productionSourceMap,
      extract: true
    })
  },
  devtool: config.build.productionSourceMap ? "#source-map" : false,
  output: {
    path: config.build.assetsRoot,
    filename: utils.assetsPath("js/[name].[chunkhash].js"),
    chunkFilename: utils.assetsPath("js/[id].[chunkhash].js")
  },
  plugins: [
    // http://vuejs.github.io/vue-loader/en/workflow/production.html
    new injectScriptPlugin({
      paths: [],
      condition: "<!-- codeInject -->",
      injectCode: "<script>var __init_res_code= '${res.code}';var __init_res_msg= '${res.msg}';</script>"
    }),
    new webpack.DefinePlugin({
      "process.env": env
    }),
    new webpack.optimize.UglifyJsPlugin({
      compress: {
        warnings: false
      },
      sourceMap: true
    }),
    // extract css into its own file
    new ExtractTextPlugin({
      filename: utils.assetsPath("css/[name].[contenthash].css")
    }),
    // Compress extracted CSS. We are using this plugin so that possible
    // duplicated CSS from different components can be deduped.
    new OptimizeCSSPlugin({
      cssProcessorOptions: {
        safe: true
      }
    }),
    // generate dist index.html with correct asset hash for caching.
    // you can customize output by editing /index.html
    // see https://github.com/ampedandwired/html-webpack-plugin
    ...configHtmlWebpackPlugin,
    // split vendor js into its own file
    new webpack.optimize.CommonsChunkPlugin({
      name: "vendor",
      minChunks: function (module, count) {
        // any required modules inside node_modules are extracted to vendor
        return (
          module.resource &&
          /\.js$/.test(module.resource) &&
          module.resource.indexOf(
            path.join(__dirname, "../node_modules")
          ) === 0
        );
      }
    }),
    // extract webpack runtime and module manifest to its own file in order to
    // prevent vendor hash from being updated whenever app bundle is updated
    new webpack.optimize.CommonsChunkPlugin({
      name: "manifest",
      chunks: ["vendor"]
    }),
    // copy custom static assets
    new CopyWebpackPlugin([
      {
        from: path.resolve(__dirname, "../static"),
        to: config.build.assetsSubDirectory,
        ignore: [".*"]
      }
    ])
  ]
});
