1、配置javascript
思路是經過node的跨域配置來調用spring boot的rest api。css
修改config\index.js文件,設置跨域配置proxyTable:html
proxyTable: { '/api': { target: 'http://localhost:18080/', changeOrigin: true, pathRewrite: { '^/api': '/' } } }
完整的config\index.js代碼以下:前端
'use strict' // Template version: 1.3.1 // see http://vuejs-templates.github.io/webpack for documentation. const path = require('path') module.exports = { dev: { // Paths assetsSubDirectory: 'static', assetsPublicPath: '/', proxyTable: { '/api': { target: 'http://localhost:18080/', changeOrigin: true, pathRewrite: { '^/api': '/' } } }, // Various Dev Server settings host: 'localhost', // can be overwritten by process.env.HOST port: 8080, // can be overwritten by process.env.PORT, if port is in use, a free one will be determined autoOpenBrowser: true, errorOverlay: true, notifyOnErrors: true, poll: false, // https://webpack.js.org/configuration/dev-server/#devserver-watchoptions- /** * Source Maps */ // https://webpack.js.org/configuration/devtool/#development devtool: 'cheap-module-eval-source-map', // If you have problems debugging vue-files in devtools, // set this to false - it *may* help // https://vue-loader.vuejs.org/en/options.html#cachebusting cacheBusting: true, cssSourceMap: true }, build: { // Template for index.html index: path.resolve(__dirname, '../dist/index.html'), // Paths assetsRoot: path.resolve(__dirname, '../dist'), assetsSubDirectory: 'static', assetsPublicPath: '/', /** * Source Maps */ productionSourceMap: true, // https://webpack.js.org/configuration/devtool/#production devtool: '#source-map', // Gzip off by default as many popular static hosts such as // Surge or Netlify already gzip all static assets for you. // Before setting to `true`, make sure to: // npm install --save-dev compression-webpack-plugin productionGzip: false, productionGzipExtensions: ['js', 'css'], // Run the build command with an extra argument to // View the bundle analyzer report after build finishes: // `npm run build --report` // Set to `true` or `false` to always turn it on or off bundleAnalyzerReport: process.env.npm_config_report } }
回到src\main.js文件中,註釋掉mock.js的配置vue
//開發模式開啓mock.js if (process.env.NODE_ENV === 'development') { // require('./mock') }
其餘任何地方都不須要修改。java
讓咱們看看具體的效果:node
觀察數據庫,發現已經保存到數據庫中了:webpack
2、總結git
上述過程無疑體現了先後端分離開發的便利性。程序員
傳統方式是:做爲前端開發者,必須等待後端程序員開發完畢以後才能作數據綁定,不然只能編寫假數據渲染到頁面上來模擬開發。等到後端開發完畢,又須要從新把頁面的假數據刪除,改用調用後端接口。這無疑增長了前端開發者的工做量。並且,當一方出現問題後,又須要協調工做才能把問題就解決。而這無疑也增長了溝通帶來的時間成本。
先後端分離方式是:先後端開發者一塊兒定義好接口的規範,而後按照這個規範並行開發。前端開發者經過mock.js模擬並測試。後端開發者經過Unit Test來測試接口。當先後端都開發完畢後,只須要修改配置就能夠了。避免了二次工做和重複性工做,並且也避免了須要等一方完成工做後本身再去工做的問題。
