spring - 在一个 Spring 上下文中使用两个调度程序

Question

我创建了一个带有两个 quartz 调度程序的 Spring 应用程序，第一个有 3 个触发器，第二个有一个触发器。

所有这些触发器都设置为并发操作 false。

当我运行它时，似乎只有第二个调度程序中的作业触发器才能获得
被解雇了。 triggerJobB 的执行时间也很少。

我的问题是，在一个 spring 上下文中使用两个调度程序是否会导致执行问题，以及这是否是一种好的做法。

<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="triggers">
            <list>
                  <ref bean="triggerJobA" />
                  <ref bean="triggerJobC" />
                  <ref bean="triggerJobD" />
            </list>
        </property>
</bean>

<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="triggers">
            <list>
                <ref bean="triggerJobB" />
            </list>
        </property>
</bean>

您需要为每个调度程序设置名称，否则 spring 只会用第二个调度程序覆盖第一个调度程序。

 <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
    <property name="schedulerName" value="SchedulerOne"/> 
    <property name="triggers">
        <list>
              <ref bean="triggerJobA" />
              <ref bean="triggerJobC" />
              <ref bean="triggerJobD" />
        </list>
    </property>
 </bean>


 <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
     <property name="schedulerName" value="SchedulerTwo"/>
     <property name="triggers">
        <list>
            <ref bean="triggerJobB" />
        </list>
    </property>
 </bean>

这样做的原因是:

The "job executor" is actually not the SchedulerFactoryBean. It is the Scheduler bean(to be precise calling its start method invokes the aggregated QuartzScheduler.start method which fires the Trigger-s), provided by the SchedulerFactoryBean. As a matter of fact this Scheduler is stored(and looked-up) under the schedulerName(which if not explicitly set has the same default value for every configured SchedulerFactoryBean) in the SchedulerRepository singleton(SchedulerRepository.getInstance()).

That's how unless you set a different schedulerName for your SchedulerFactoryBean-s, you will always get the same scheduler by each and every SchedulerFactoryBean-s
