注意事项

由于Go是不支持热编译特性的，每一次代码变更后都要重新手动停止、编译、运行代码文件。run命令也不是实现热编译功能，而是提供了自动编译功能，当开发者修改了项目中的go文件时，该命令将会自动编译当前程序，并停止原有程序，运行新版的程序。

run命令会递归监控当前运行目录的所有go文件变化来实现自动编译。

  1. $ gf run -h 
  2. USAGE
  3.     gf run FILE [OPTION]
  5. ARGUMENT

  14.     gf run main.go
  15.     gf run main.go --args "server -p 8080"
  16.     gf run main.go -mod=vendor
  18. DESCRIPTION

一般gf run main.go即可
