VsCode配置Java环境

• 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的破解版魔咒，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

• 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
    

• Ctrl + Shift + P，输入setting，选择JSON
