@MidGap 再请教个问题，
我是通过 supervisor 来守护 go
我通过 supervisorctl stop program 关闭程序
然后再重启的时候，报接口被占用的错误
2023/01/11 22:38:38 listen: listen tcp :8000: bind: address already in use

我已经配置了优化退出，还是出问题。

package main

import (
"context"
"log"
"net/http"
"os"
"os/signal"
"time"

"github.com/gin-gonic/gin"
)

func main() {
router := gin.Default()
router.GET("/", func(c *gin.Context) {
time.Sleep(5 * time.Second)
c.String( http.StatusOK, "Welcome Gin Server")
})

srv := &http.Server{
Addr: ":8080",
Handler: router,
}

go func() {
// 服务连接
if err := srv.ListenAndServe(); err != nil && err != http.ErrServerClosed {
log.Fatalf("listen: %s\n", err)
}
}()

// 等待中断信号以优雅地关闭服务器（设置 5 秒的超时时间）
quit := make(chan os.Signal)
signal.Notify(quit, os.Interrupt)
<-quit
log.Println("Shutdown Server ...")

ctx, cancel := context.WithTimeout(context.Background(), 5*time.Second)
defer cancel()
if err := srv.Shutdown(ctx); err != nil {
log.Fatal("Server Shutdown:", err)
}
log.Println("Server exiting")
}
