我们正在努力做一件看起来非常简单的事情,但它不起作用,我在网上找到的解决方案似乎很复杂,因为我觉得我应该再问一次。 我们有一个在tomcat下运行的Spring Web应用程序。我们在其中添加了Quartz调度程序:
<bean id="myScheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="dataSource" ref="myDataSource"/>
<property name="transactionManager" ref="myTransactionManager"/>
<property name="overwriteExistingJobs" value="true"/>
<property name="autoStartup" value="true"/>
<property name="jobFactory">
<bean class="AutowiringSpringBeanJobFactory"/>
</property>
<!-- NOTE: Must add both the jobDetail and trigger to the scheduler! -->
<property name="jobDetails">
<list>
<ref bean="jobDetailAutoSendPublishedReport" />
</list>
</property>
<property name="triggers">
<list>
<ref bean="cronTriggerAutoSendPublishedReport"/>
</list>
</property>
<property name="quartzProperties">
<props>
<!-- Main Scheduler Properties For A Clustered Scheduler -->
<prop key="org.quartz.scheduler.instanceName">test</prop>
<prop key="org.quartz.scheduler.instanceId">AUTO</prop>
<prop key="org.quartz.scheduler.skipUpdateCheck">true</prop>
<prop key="org.quartz.scheduler.idleWaitTime">60000</prop>
<!-- ThreadPool -->
<prop key="org.quartz.threadPool.class">org.quartz.simpl.SimpleThreadPool</prop>
<prop key="org.quartz.threadPool.threadCount">5</prop>
<!-- Shutdown Hook Plugin -->
<!--prop key="org.quartz.plugin.shutdownhook.class">org.quartz.plugins.management.ShutdownHookPlugin</prop>
<prop key="org.quartz.plugin.shutdownhook.cleanShutdown">true</prop-->
<!-- JDBC JobStore -->
<prop key="org.quartz.jobStore.class">org.quartz.impl.jdbcjobstore.JobStoreTX</prop>
<prop key="org.quartz.jobStore.driverDelegateClass">org.quartz.impl.jdbcjobstore.oracle.OracleDelegate</prop>
<prop key="org.quartz.jobStore.useProperties">false</prop>
<prop key="org.quartz.jobStore.isClustered">true</prop>
<prop key="org.quartz.jobStore.clusterCheckinInterval">300000</prop>
<prop key="org.quartz.jobStore.misfireThreshold">300000</prop>
</props>
</property>
</bean>
然后当我尝试关闭tomcat时,我收到以下错误并关闭tomcat fials:
似乎已经启动了一个名为[DefaultQuartzScheduler_QuartzSchedulerThread]但未能阻止它的线程。这很可能造成内存泄漏。 2015年1月27日上午1:09:35 org.apache.catalina.loader.WebappClassLoader checkThreadLocalMapForLeaks
我的修复是将以下内容添加到web.xml:
<!-- Start Quartz -->
<listener>
<listener-class>
org.quartz.ee.servlet.QuartzInitializerListener
</listener-class>
</listener>
<context-param>
<param-name>quartz:shutdown-on-unload</param-name>
<param-value>true</param-value>
</context-param>
<context-param>
<param-name>quartz:wait-on-shutdown</param-name>
<param-value>true</param-value>
</context-param>
<context-param>
<param-name>quartz:start-on-load</param-name>
<param-value>false</param-value> <!-- let spring handle starting -->
</context-param>
<!-- End of Quartz -->
答案 0 :(得分:2)
在docs中显示:
如果使用org.quartz.ee.servlet.QuartzInitializerListener在servlet容器中启动调度程序,则当取消部署应用程序或应用程序服务器关闭时,其contextDestroyed()方法将关闭调度程序。
也许你也可以添加这个监听器。
