Quartz job Cluster下报错
问题
Cluster环境下,配置Quartz job为集群模式后,配置示例如下,其中红色部分与集群模式相关。我使用的是quartz-all-1.6.0,spring-context-support-3.0.1。
1 <bean id="startQuertz" lazy-init="false" autowire="no" 2 class="org.springframework.scheduling.quartz.SchedulerFactoryBean"> 3 <property name="triggers"> 4 <list> 5 <ref bean="jobTrigger" /> 6 </list> 7 </property> 8 <property name="dataSource" ref="dataSource" /> 9 <property name="transactionManager" ref="transactionManager" /> 10 <property name="quartzProperties"> 11 <props> 12 <prop key="org.quartz.scheduler.instanceName">DataScheduler</prop> 13 <prop key="org.quartz.scheduler.instanceId">AUTO</prop> 14 <prop key="org.quartz.threadPool.class">org.quartz.simpl.SimpleThreadPool</prop> 15 <prop key="org.quartz.threadPool.threadCount">5</prop> 16 <prop key="org.quartz.threadPool.threadPriority">5</prop> 17 <prop key="org.quartz.jobStore.misfireThreshold">60000</prop> 18 <prop key="org.quartz.jobStore.class">org.springframework.scheduling.quartz.LocalDataSourceJobStore</prop> 19 <prop key="org.quartz.jobStore.tablePrefix">QRTZ_</prop> 20 <prop key="org.quartz.jobStore.isClustered">true</prop> 21 <prop key="org.quartz.jobStore.useProperties">false </prop> 22 </props> 23 </property> 24 </bean>
但系统运行Quartz job抛出如下的错误信息:
1 Caused by: org.quartz.JobPersistenceException: Couldn't store job: Unable to serialize JobDataMap for insertion into database because the value of property 'methodInvoker' is not serializable: org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean [See nested exception: java.io.NotSerializableException: Unable to serialize JobDataMap for insertion into database because the value of property 'methodInvoker' is not serializable: org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean] 2 at org.quartz.impl.jdbcjobstore.JobStoreSupport.storeJob(JobStoreSupport.java:1041) 3 at org.quartz.impl.jdbcjobstore.JobStoreSupport$4.execute(JobStoreSupport.java:1011) 4 at org.quartz.impl.jdbcjobstore.JobStoreSupport$39.execute(JobStoreSupport.java:3590) 5 at org.quartz.impl.jdbcjobstore.JobStoreCMT.executeInLock(JobStoreCMT.java:244) 6 at org.quartz.impl.jdbcjobstore.JobStoreSupport.executeInLock(JobStoreSupport.java:3586) 7 at org.quartz.impl.jdbcjobstore.JobStoreSupport.storeJob(JobStoreSupport.java:1007) 8 at org.quartz.core.QuartzScheduler.addJob(QuartzScheduler.java:785) 9 at org.quartz.impl.StdScheduler.addJob(StdScheduler.java:278) 10 at org.springframework.scheduling.quartz.SchedulerAccessor.addJobToScheduler(SchedulerAccessor.java:311) 11 at org.springframework.scheduling.quartz.SchedulerAccessor.addTriggerToScheduler(SchedulerAccessor.java:334) 12 at org.springframework.scheduling.quartz.SchedulerAccessor.registerJobsAndTriggers(SchedulerAccessor.java:271) 13 at org.springframework.scheduling.quartz.SchedulerFactoryBean.afterPropertiesSet(SchedulerFactoryBean.java:513)
网上google一番,发现这个是Spring的一个Bug,详情参见:http://forum.springsource.org/showthread.php?31820-Quartz-and-JDBCJobStore,按照论坛中的方案修改Spring包中的2个java文件后解决。
其他的注意事项
1. Quartz job类要实现java.io.Serializable接口,不然还是会报NotSerializableException的异常。
2. Quartz job类的属性也要实现java.io.Serializable接口。
