webpack配置npm自启动后跳转到0.0.0.0的问题解决

在package.json的scripts里的serve后面追加‘--open’，表示执行完npm run serve后，自动跳转到浏览器

{
  "name": "springboot-vue-demo",
  "version": "0.1.0",
  "private": true,
  "scripts": {
    "serve": "vue-cli-service serve --open",
    "build": "vue-cli-service build"
  },
  "dependencies": {
    "core-js": "^3.8.3",
    "vue": "^3.2.13",
    "vue-router": "^4.0.3",
    "vuex": "^4.0.0"
  },
  "devDependencies": {
    "@vue/cli-plugin-babel": "~5.0.0",
    "@vue/cli-plugin-router": "~5.0.0",
    "@vue/cli-plugin-vuex": "~5.0.0",
    "@vue/cli-service": "~5.0.0"
  },
  "browserslist": [
    "> 1%",
    "last 2 versions",
    "not dead",
    "not ie 11"
  ]
}

然年运行结果http://0.0.0.0:8080/

原来是需要修改vue里的配置，找到

node_modules/@vue/cli-service/lib/commands/serve.js

在host:'0.0.0.0'后面修改为‘127.0.0.1’ 

保存重新启动就可以了
