spring+quartz分布式配置

quartz利用自带的表实现分布式，有一个节点执行的时候其他节点不会发生执行。

1.下载quartz-2.2.1包，quartz-2.2.1\docs\dbTables里面有想要执行的脚本文件。我用的是tables_mysql_innodb.sql进行执行，记得表结构要改成innerDB,不然会报错。然后maven引入quartz(2.2.3),quartz-jobs(2.2.3),spring-context-suppor(4.2.6.RELEASE)t包

2.创建quartz.properties文件

org.quartz.scheduler.instanceName: DefaultQuartzScheduler
org.quartz.scheduler.instanceId: AUTO
org.quartz.scheduler.rmi.export: false
org.quartz.scheduler.rmi.proxy: false
org.quartz.scheduler.wrapJobExecutionInUserTransaction: false

org.quartz.threadPool.class: org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount: 15
org.quartz.threadPool.threadPriority: 5
org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread: true

org.quartz.jobStore.misfireThreshold: 60000
org.quartz.jobStore.maxMisfiresToHandleAtATime: 1

#org.quartz.jobStore.class: org.quartz.simpl.RAMJobStore

# for cluster
org.quartz.jobStore.tablePrefix = QRTZ_
org.quartz.jobStore.class: org.quartz.impl.jdbcjobstore.JobStoreTX
org.quartz.jobStore.isClustered: true
org.quartz.jobStore.clusterCheckinInterval: 5000

3.在spring-quartz.xml里面添加相关配置信息

 <bean id="jobDetail" class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
        <property name="jobClass" value="com.test.service.JobTask"/>
        <property name="durability" value="true"/>
        <property name="requestsRecovery" value="true"/>
    </bean>

    <bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
        <property name="jobDetail" ref="jobDetail"/>
        <property name="cronExpression" value="0/10 * * * * ?"/>
    </bean>

    <bean name="quartzScheduler"
          class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="quartzProperties">
            <props>
                <prop key="org.quartz.scheduler.instanceName">SpringQuartzCluster</prop>
                <prop key="org.quartz.scheduler.instanceId">AUTO</prop>
<!--                 线程池配置
 -->                <prop key="org.quartz.threadPool.class">org.quartz.simpl.SimpleThreadPool</prop>
                <prop key="org.quartz.threadPool.threadCount">20</prop>
                <prop key="org.quartz.threadPool.threadPriority">5</prop>
<!--                 JobStore 配置
 -->                <prop key="org.quartz.jobStore.class">org.quartz.impl.jdbcjobstore.JobStoreTX</prop>
<!--                 集群配置
 -->                <prop key="org.quartz.jobStore.isClustered">true</prop>
                <prop key="org.quartz.jobStore.clusterCheckinInterval">15000</prop>
                <prop key="org.quartz.jobStore.maxMisfiresToHandleAtATime">1</prop>
                <prop key="org.quartz.jobStore.misfireThreshold">120000</prop>
                <prop key="org.quartz.jobStore.tablePrefix">QRTZ_</prop>
            </props>

        </property>

        <property name="schedulerName" value="SpringQuartzCluster"/>

<!--         必须的，QuartzScheduler 延时启动，应用启动完后 QuartzScheduler 再启动
 -->        <property name="startupDelay" value="30"/>

        <property name="applicationContextSchedulerContextKey" value="applicationContextKey"/>

<!--         可选，QuartzScheduler 启动时更新己存在的Job，这样就不用每次修改targetObject后删除qrtz_job_details表对应记录了
 -->        <property name="overwriteExistingJobs" value="true"/>

     <!--    设置自动启动 -->
        <property name="autoStartup" value="true"/>

        <property name="configLocation" value="classpath:quartz.properties"/>

        <property name="jobDetails">
            <list>
                <ref bean="jobDetail"/>
            </list>
        </property>
        <property name="triggers">
            <list>
                <ref bean="cronTrigger"/>
            </list>
        </property>
    </bean> 

4.java代码

@PersistJobDataAfterExecution
@DisallowConcurrentExecution
@Service
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("/spring-config.xml")
public class JobTask extends QuartzJobBean {

	private Log log = LogFactory.getLog(JobTask.class);
    @Override
    protected void executeInternal(JobExecutionContext jobExecutionContext) throws JobExecutionException {
        System.out.println("#########################################定時器執行"+DateUtil.getSimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date())+"#############################################");
    }

}
