go 监听 ctrl+c 退出程序信号

代码实现

package main

import (
	"log"
	"os"
	"os/signal"
	"syscall"
)

func main() {

	//TODO 协程执行业务代码

	//监听退出序号
	sigs := make(chan os.Signal, 1)
	done := make(chan bool, 1)
	signal.Notify(sigs, syscall.SIGINT, syscall.SIGTERM)
	go func() {
		sig := <-sigs
		log.Println(sig)
		done <- true
	}()
	log.Println("Server Start Awaiting Signal")
	<-done
	log.Println("Exiting")
}
