vue项目如何部署到Tomcat中

1，假设你要访问的项目名称为‘hms’

2，在Tomcat的webapps下创建hms文件夹，

3，配置config/index.js文件，build: {} 选项里面 设置assetsPublicPath: '/hms/'

​ （解释：这里改为这个配置之后，最后编译产生的index.html中相关路径也会带上‘/hms’,不会报404的错误了）

'use strict'

// Template version: 1.2.6

// see http://vuejs-templates.github.io/webpack for documentation.

const path = require('path')

module.exports = {

  dev: {

    // Paths

    assetsSubDirectory: 'static',

    assetsPublicPath: '/',

    proxyTable: {},

    // Various Dev Server settings

    host: 'localhost', // can be overwritten by process.env.HOST

    port: 8013, // can be overwritten by process.env.PORT, if port is in use, a free one will be determined

    autoOpenBrowser: true,

    errorOverlay: true,

    notifyOnErrors: false,

    poll: false, // https://webpack.js.org/configuration/dev-server/#devserver-watchoptions-

    // Use Eslint Loader?

    // If true, your code will be linted during bundling and

    // linting errors and warnings will be shown in the console.

    useEslint: false,

    // If true, eslint errors and warnings will also be shown in the error overlay

    // in the browser.

    showEslintErrorsInOverlay: false,

    /**

     * Source Maps

     */

    // https://webpack.js.org/configuration/devtool/#development

    devtool: 'cheap-source-map',

    // CSS Sourcemaps off by default because relative paths are "buggy"

    // with this option, according to the CSS-Loader README

    // (https://github.com/webpack/css-loader#sourcemaps)

    // In our experience, they generally work as expected,

    // just be aware of this issue when enabling this option.

    cssSourceMap: false

  },

  build: {

    // Template for index.html

    index: path.resolve(__dirname, '../dist/index.html'),

    // Paths

    assetsRoot: path.resolve(__dirname, '../dist'),

    assetsSubDirectory: 'static',

    /**

     * You can set by youself according to actual condition

     * You will need to set this if you plan to deploy your site under a sub path,

     * for example GitHub pages. If you plan to deploy your site to https://foo.github.io/bar/,

     * then assetsPublicPath should be set to "/bar/".

     * In most cases please use '/' !!!

     */

    // assetsPublicPath: '/',

    assetsPublicPath: '/hms/',

    /**

     * Source Maps

     */

    productionSourceMap: false,

    // 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 || false,

    // `npm run build:prod --generate_report`

    generateAnalyzerReport: process.env.npm_config_generate_report || false

  }

}

使用vue-router的情况

当你在项目中使用vue-router的时候，就需要给src/router/index.js添点东西，如下面：

export default new Router({

  mode : 'history',

  base: '/hms/',  //添加的地方

  ...

 }

4，在项目运行“npm run build:prod”命令，生成dist文件夹，dist文件夹中包含static和index.html

5，将dist文件夹中static和index.html复制到Tomcat中webapps的hms文件夹中

6，启动Tomcat，ip:port/hms，例如：http://localhost:8080/hms/即可访问到Vue项目。
