  from datetime import  datetime
  from trigger_manage import TriggerManager
  import time
  
  
  def tick(**kwargs):
      print('Hi  %s Tick! The time is: %s' % (kwargs['name'], datetime.now()))
  
  if __name__ == '__main__':
      scheduler = BackgroundScheduler()
      # 触发器设置每隔多少时间执行一次  {"timeInterval": 5, "timeUnit": 's'}表示每隔5秒触发一次
      trigger = TriggerManager.interval_trigger(conf={"timeInterval": 5, "timeUnit": 's'})
  
      # 添加任务：指定执行的函数、触发器、函数的参数、任务的id(唯一标识，方便根据id修改、删除任务)
      scheduler.add_job(tick, trigger,
                        kwargs={
                            "name": "leo"
                        },
                        id="1")
      scheduler.add_job(tick, trigger,
                        kwargs={
                            "name": "bob"
                        },
                        id="2")
      scheduler.start()
  
      #  BackgroundScheduler 运行在Backgroud，但是并不会阻止主程序自己终止，而主程序终止后，BackgroundScheduler 也会终止。
      #  所以要主线程一直执行
      try:
          # 模拟主进程持续运行
          while True:
              time.sleep(2)
              # print('sleep')
      except(KeyboardInterrupt, SystemExit):
          # Not strictly necessary if daemonic mode is enabled but should be done if possible
          scheduler.shutdown()
          print('Exit The Job!')
