1.安装vscode

官网地址：https://code.visualstudio.com/

2.安装一个插件，识别vue文件

插件库中搜索Vetur，下图中的第一个，点击安装，安装完成之后点击重新加载

3.新建代码片段

文件-->首选项-->用户代码片段-->点击新建代码片段--取名vue.json 确定

4.删除不要的代码
5.粘入自己写的.vue模板

{"Print to console": {"prefix": "vue","body": ["<!-- $1 -->","<template>","<div class='$2'>$5</div>","</template>","","<script>","//这里可以导入其他文件（比如：组件，工具js，第三方插件js，json文件，图片文件等等）","//例如：import 《组件名称》 from '《组件路径》';","","export default {","//import引入的组件需要注入到对象中才能使用","components: {},","data() {","//这里存放数据","return {","","};","},","//监听属性 类似于data概念","computed: {},","//监控data中的数据变化","watch: {},","//方法集合","methods: {","","},","//生命周期 - 创建完成（可以访问当前this实例）","created() {","","},","//生命周期 - 挂载完成（可以访问DOM元素）","mounted() {","","},","beforeCreate() {}, //生命周期 - 创建之前","beforeMount() {}, //生命周期 - 挂载之前","beforeUpdate() {}, //生命周期 - 更新之前","updated() {}, //生命周期 - 更新之后","beforeDestroy() {}, //生命周期 - 销毁之前","destroyed() {}, //生命周期 - 销毁完成","activated() {}, //如果页面有keep-alive缓存功能，这个函数会触发","}","</script>","<style lang='scss' scoped>","//@import url($3); 引入公共css类","$4","</style>"],"description": "Log output to console"}
}

6.上面代码中的 “prefix”: “vue”, 就是快捷键；保存好之后，新建.vue结尾的文件试试
