当前前后端架构分离的模式比较流行,前端用Nodejs或者ngnix等方式发布与渲染网页,后端程序只提供restful的数据接口。但对于一些小项目来说,并不想让前后端如此分离,还是希望用spring-boot的内置tomcat来serve static content。
如果只是用前端工具的话,webpack是一个很好的打包方式,webpack-dev-server给我们提供了很好的在线调试与修改。但是与spring-boot结合起来就不太协调。这时候就可以用到webpack-dev-server的代理模式了。通过webpack-dev-server来代理spring-boot中tomcat的端口(默认8080)
这里贴出我的一个配置文件
// webpack.config.jsvar path = require('path');var webpack = require('webpack');var HtmlWebpackPlugin = require('html-webpack-plugin');module.exports = { devtool: "source-map", entry: [ "webpack-dev-server/client?http://localhost:3000", "webpack/hot/only-dev-server", "./src/main/web/index.js" ], output: { path: "./src/main/resources/static", filename: "index.js", publicPath: 'http://localhost:3000/' }, module: { loaders: [ {test: /\.css$/, loader: "style!css"}, { test: /\.js$/, loader: "babel-loader", exclude: /node_modules/, query: { presets: ['es2015'] } }, { test: /\.(png|jpg|jpeg|gif|woff)$/, loader: 'url-loader?limit=8192' }, { test: /\.html$/, loader: 'html'}, ] }, plugins: [ new webpack.HotModuleReplacementPlugin(), new webpack.NoErrorsPlugin(), new HtmlWebpackPlugin({ template: './src/main/web/index.tmpl' })], devServer: { port: 3000, proxy: { '**': { target: 'http://localhost:8080', secure: false, prependPath: false } }, publicPath: 'http://localhost:3000/', historyApiFallback: true }};
在这里我们可以看到,通过webpack-dev-server的3000端口去代理8080端口。在package.json中添加
"scripts": { "webpack": "webpack", "watch": "webpack-dev-server --inline" },
之后直接启动spring boot程序,然后npm run watch
就可以通过访问3000端口来进行前端的热开发了
