Java – quartz triggers the bean cache problem twice?

Spring report XML will

<bean id="scheduleReportEmailJob"
      class="org.springframework.scheduling.quartz.JobDetailBean">
    <property name="jobClass"
              value="schedule.ReportQuartzJobBean"/>
    <property name="jobDataAsMap">
        <map>
            <entry key="reportService" value-ref="reportService"/>
        </map>
    </property>
</bean>

<bean id="cronEmailTrigger"
      class="org.springframework.scheduling.quartz.crontriggerBean">
    <property name="jobDetail" ref="scheduleReportEmailJob"/>
    <property name="cronExpression" value="0 0,15,30,45 * ? * MON-FRI"/>
</bean>

<bean id="scheduler" class="org.springframework.scheduling.quartz.Schedulerfactorybean">
    <property name="triggers">
        <list>
            <ref bean="cronEmailTrigger"/>
        </list>
    </property>
    <property name="quartzProperties">
        <props>
            <prop key="org.quartz.scheduler.instanceName">Reports</prop>
            <prop key="org.quartz.scheduler.instanceId">FirstInstance</prop>
            <prop key="org.quartz.scheduler.rmi.export">false</prop>
            <prop key="org.quartz.scheduler.rmi.proxy">false</prop>
            <prop key="org.quartz.threadPool.class">org.quartz.simpl.SimpleThreadPool</prop>
            <prop key="org.quartz.threadPool.threadCount">1</prop>
            <prop key="org.quartz.jobStore.class">org.quartz.simpl.RAMJobStore</prop>
            <prop key="org.quartz.scheduler.jobFactory.class">org.quartz.simpl.SimpleJobFactory</prop>
        </props>
    </property>
</bean>

private static beanfactory factory = new ClassPathXmlApplicationContext("spring-report.xml");

When I start Tomcat

After a period of time after I start tomcat, jobs will be activated twice. If I delete all caches from the working directory and the exploded war file and redeploy it, the job will only be activated once Any ideas? Maybe some beans?

@Jhouse redeployment seems to be a problem that I pasted thread dump after redeployment. What is my choice?

If I stop the server, then check that the thread dump is empty, and then start (do not clean up) the server, the thread pump has duplicate threads running

Solution

I wonder if you are also on the web Spring report. XML is configured xml？ like this?

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        classpath:spring-report.xml
    </param-value>
</context-param>

The reason I ask is because you made the above statement: –

private static beanfactory factory = new ClassPathXmlApplicationContext("spring-report.xml");

If you're on the web Both XML and Java code have spring report XML, then yes, it may activate the job twice
