使用 Quartz Cron 触发器处理夏令时的方法 [英] Ways to deal with Daylight Savings time with Quartz Cron Trigger

问题描述

我有一个看起来像这样的石英 cron 触发器:

I have a quartz cron trigger that looks like so:

<bean id="batchProcessCronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
    <property name="jobDetail" ref="batchProcessJobDetail" />
    <property name="cronExpression" value="0 30 2 * * ?" />
</bean>

如果我在凌晨 2-3 点期间发生了多个配置，我应该如何解决这个问题?是否有公认的最佳做法?

How should I solve this, if I have several configurations that happen within the 2-3am period? Is there an accepted best practice?

基本上它说处理它".但我的问题是如何！

Basically it says "Deal with it." But my question is how!

推荐答案

我使用单独的触发器解决了这个问题，该触发器仅在东部时间凌晨 2 点到凌晨 3 点之间发生的配置在夏令时开始日期触发(提前一小时).

I solved it using a separate trigger that only fires (an hour early) on the beginning date of DST for the configurations that happen between 2am and 3am Eastern.

看起来很笨拙，但确实有效...

Seems kludgey, but it works...
