Question

我在单个bean中使用以下@Schdule注释每分钟打勾一个自动收报机方法：

@Schedule(minute = "*/1", hour = "*", persistent = false)
public void tick() {
            for (ScheduledTask scheduledTask : scheduledTasks) {
                    logger.info("Start Task [" + scheduledTask.toString() + "]");
                    taskHandler.handleScheduledTask(scheduledTask);
                }
            }

其中taskHandler是另一个单一bean，以下是handleScheduledTask方法：

@Override
@Asynchronous
public void handleScheduledTask(ScheduledTask task) {
         .
         .
         .
 // handle the scheduled task ....
         .

}

但是，有时候滴答方法可能会在2分钟后调用。在这种情况下，服务器日志中出现以下错误，并且不再调用tick方法

我通过保留调度程序计时器解决了这个问题：

@Schedule(minute = "*/1", hour = "*", persistent = true)
public void tick() {
            for (ScheduledTask scheduledTask : scheduledTasks) {
                    logger.info("Start Task [" + scheduledTask.toString() + "]");
                    taskHandler.handleScheduledTask(scheduledTask);
                }
            }

到目前为止，这解决了问题并且每分钟执行tick方法

@Schedule计时器导致服务器systemException
