cron触发器的问题 [英] problem with cron trigger

问题描述

有什么方法可以设置cron触发器的结束时间。是否可以编辑一个执行的cron作业。例如：我想在cron作业中设置开始时间，触发间隔和结束时间，并且可能希望在调度程序启动后更改更改触发间隔或结束时间。

s there any way to set end time for a cron trigger. Is it possible to edit one cron job executing. for eg: I want to set start time, trigger interval and end time in a cron job, and it may want to change change trigger interval or end time after scheduler start it.

推荐答案

我自己没有尝试过，但是我这样做的方法是创建第二个cron作业，杀死第一个。

I haven''t tried this myself but the way I would do it is to create a second cron job that kills the first one.

如果你指的是Quartz Schedular中的Cron Job，那么这里[ ^ ]很好的教程。



问候，

Hi,

If you are referring to Cron Job in Quartz Schedular, then here[^] good tutorial.

示例代码设置开始时间



ct = new CronTrigger（cronTrigger，group，cronExpression）;



日历futureDate =日历。 getInstance（）;

futureDate.set（Calendar.YEAR，2013）;

futureDate.set（Calendar.MONTH，GregorianCalendar.MARCH）;

futureDate.set（Calendar.DAY_OF_MONTH，

futureDate.set（Ca） lendar.HOUR_OF_DAY，13）;

futureDate.set（Calendar.MINUTE，15）;

futureDate.set（Calendar.SECOND，10）;

futureDate.set（Calendar.MILLISECOND，0）;

ct.setStartTime（futureDate.getTime（））;



和结束时间：



日历ffutureDate = Calendar.getInstance（）;

ffutureDate.set（Calendar.YEAR，20143）;

ffutureDate.set（Calendar.MONTH，GregorianCalendar.MARCH）;

ffutureDate.set（Calendar.DAY_OF_MONTH，18）;

ffutureDate.set（ Calendar.HOUR_OF_DAY，9）;

ffutureDate.set（Calendar.MINUTE，58）;

ffutureDate.set（Calendar.SECOND，15）;

ffutureDate.set（Calendar.MILLISECOND，0）;

ct.setEndTime（ffutureDate.getTime（））;

sample code to set start time

ct = new CronTrigger("cronTrigger", "group", cronExpression);

Calendar futureDate = Calendar.getInstance();
futureDate.set(Calendar.YEAR, 2013);
futureDate.set(Calendar.MONTH, GregorianCalendar.MARCH);
futureDate.set(Calendar.DAY_OF_MONTH,
futureDate.set(Calendar.HOUR_OF_DAY, 13);
futureDate.set(Calendar.MINUTE, 15);
futureDate.set(Calendar.SECOND, 10);
futureDate.set(Calendar.MILLISECOND, 0);
ct.setStartTime(futureDate.getTime());

and for end time:

Calendar ffutureDate = Calendar.getInstance();
ffutureDate.set(Calendar.YEAR, 20143);
ffutureDate.set(Calendar.MONTH, GregorianCalendar.MARCH);
ffutureDate.set(Calendar.DAY_OF_MONTH, 18);
ffutureDate.set(Calendar.HOUR_OF_DAY, 9);
ffutureDate.set(Calendar.MINUTE, 58);
ffutureDate.set(Calendar.SECOND, 15);
ffutureDate.set(Calendar.MILLISECOND, 0);
ct.setEndTime(ffutureDate.getTime());
