原因

Idea启动慢，过于冗杂，VsCode很轻量
有时需要启动前端代码，不想使用Idea
逃离Idea的激活成功教程版魔咒，哈哈哈
最近在学Rust，Idea对Rust的支持不是很好

建议大家还是看看，里面有比较完备的介绍官方文档

插件

Extension Pack for Java
- 只用下载第一个，其他的会自动下载
- Language Support for Java有点坑，这个得要Java 11才行，官网上没看到他们说的0.6.x的历史版本
- 不过不影响使用Java 1.8
Spring Boot Extension Pack
- 这也是个全家桶

插件设置

Ctrl + Shift + P，输入setting，选择JSON
