beego-toolbox的定时任务的使用

参考文章：beego.top/example/too…

beego里的toolbox.StartTask()是有协程go出去，所以需要加个协程锁，保证子协程能执行完。

package main

import (
	"sync"
	"time"

	"github.com/astaxie/beego/logs"
	"github.com/astaxie/beego/toolbox"
)

var TimerWg sync.WaitGroup

func generateWarning() error {
	defer TimerWg.Done()
	logs.Error("hello time:%v", time.Now())
	return nil
}

func main() {
	TimerWg = sync.WaitGroup{}
	TimerWg.Add(1)
	logs.Debug("start :%v", time.Now())
	tk := toolbox.NewTask("generateWarning", "0 59 17 * * *", generateWarning)
	toolbox.AddTask("generateWarning", tk)
	toolbox.StartTask()
	logs.Debug("StartTask :%v", time.Now())
	defer toolbox.StopTask()
	TimerWg.Wait()
	logs.Debug("Wait :%v", time.Now())

}

输出：
