Quartz job Cluster下报错

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]

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。
