开发web api或web项目，修改源码后，无需手动重启即可查看效果，使用air即可实现。
安装air：go get -v -u github.com/cosmtrek/air（或下载所有源码后，go build，得到air.exe，拷贝到$goroot/bin目录）
在项目目录下，创建.air.config文件，修改[build]中的cmd配置，设置为goland编译程序的命令行命令：
cmd = "go build -o ./tmp/xxx-demo.exe ./main.go"
最终配置文件如下：
# Config file for [Air](https://github.com/cosmtrek/air) in TOML format # Working directory # . or absolute path, please note that the directories following must be under root. root = "." tmp_dir = "tmp" [build] # Just plain old shell command. You could use `make` as well. cmd = "go build -o ./tmp/xxx-demo.exe ./main.go" # Binary file yields from `cmd`. bin = "tmp/xxx-demo.exe" # Customize binary. full_bin = "APP_ENV=dev APP_USER=air ./tmp/main" # Watch these filename extensions. include_ext = ["go", "tpl", "tmpl", "html"] # Ignore these filename extensions or directories. exclude_dir = ["assets", "tmp", "vendor", "frontend/node_modules"] # Watch these directories if you specified. include_dir = [] # Exclude files. exclude_file = [] # It's not necessary to trigger build each time file changes if it's too frequent. delay = 1000 # ms # Stop to run old binary when build errors occur. stop_on_error = true # This log file places in your tmp_dir. log = "air_errors.log" [log] # Show log time time = false [color] # Customize each part's color. If no color found, use the raw app log. main = "magenta" watcher = "cyan" build = "yellow" runner = "green" [misc] # Delete tmp directory on exit clean_on_exit = true
goland中打开项目，在Terminal中运行air命令，即可自动监控项目代码修改，自动热启动服务，方便开发调试。
