使用Spring + quartz集群持久化时注意事项

1、持久化时未序列化异常

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

例如：

    <bean id="studyDetail"  
        class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">  
        <property name="targetObject">  
            <ref bean="studyJob" />  
        </property>  
        <property name="targetMethod">  
            <value>doSth</value>  
        </property>  
    </bean> 

原因请看org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean

NOTE: JobDetails created via this FactoryBean are not serializable and thus not suitable for persistent job stores. You need to implement your own Quartz Job as a thin wrapper for each case where you want a persistent job to delegate to a specific service method.

Compatible with Quartz 1.5+ as well as Quartz 2.0-2.2, as of Spring 3.2.

所以对于持久化的job需要自己继承org.springframework.scheduling.quartz.QuartzJobBean，同时修改JobDetailFactoryBean为

 <bean id="studyDetail"
		class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
		<property name="jobClass">
			<value>com.joshua.job.StudyJob</value>
		</property>
		<property name="name" value="studyDetail"></property>
		<property name="durability" value="true" />
	</bean> 

2.持久化时jobDetail找不到

org.quartz.JobPersistenceException: The job (DEFAULT.studyDetail) referenced by the trigger does not exist.

原因一般是数据源配置导致的问题。

可能的原因是：数据源未配置成自动提交，当第一次启动trigger时，之前对数据库的job的增加的事物没有自动提交，导致后面的事物无法查询到。

如果数据源是通过dbcp配置的将自动提交配置为true

<property name="defaultAutoCommit" value="false" />

如果是c3p0配置为autoCommitOnClose=true
