在Spring中使用Quartz任务调度支持集群（转载）
虽然在Quartz上有配置Quartz集群Clustering ，但是在Spring中使用Quartz任务调度并支持集群系统却有些问题，下面介绍解决办法：
环境：（环境非常重要，注意版本号）
Spring-1.2.7：spring.jar-1.2.7.jar
Quartz-1.5.2：quartz-1.5.2.jar，quartz-oracle-1.5.2.jar
Oracle10G：
org.springframework.scheduling.quartz.CronTriggerBean与Quartz版本依赖情况：NOTE: This convenience subclass does not work with trigger persistence in Quartz 1.6,due to a change in Quartz's trigger handling. Use Quartz 1.5 if you rely on triggerpersistence based on this class, or the standard Quartz CronTrigger class instead.org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean在使用 org.quartz.impl.jdbcjobstore.JobStoreTX的支持情况： 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.所以，Quartz集群只支持JDBCJobStore存储方式，而MethodInvokingJobDetailFactoryBean不能序列化存储job数据到数据库，所以需要手工编写任务调度类继承QuartzJobBean，否则报如下错误：ERROR [org.springframework.web.context.ContextLoader] Context initialization failed org.springframework.beans.factory.BeanCreationExce ption: Error creating bean with name 'schedulerFactoryBean' definedin ServletContext resource [/WEB-INF/classes/tim-quartz.xml]: Invocation of init method failed;nested exception is org.quartz.JobPersistenceException: Couldn't store job: Unable to serialize JobDataMap for insertioninto database because the value of property 'methodInvoker' is not serializable:org.springframework.scheduling.quartz.MethodInvoki ngJobDetailFactoryBean [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.MethodInvoki ngJobDetailFactoryBean]

Method m=null;
try {

} catch (SecurityException e) {

e.printStackTrace();
} catch (NoSuchMethodException e) {
// TODO Auto-generated catch block

}
}
catch(Exception e)
{
throw new JobExecutionException(e);
}
finally
{
logger.debug("end");
}
}public void setTargetObject(String targetObject) {
this.targetObject = targetObject;

this.targetMethod = targetMethod;

前辈，你这篇文章就是及时雨啊。我这几天正在搞这个jobstore。可是现在遇到个问题，放狗都搜不到什么东西。 008-10-08 15:48:09,806 org.springframework.web.context.ContextLoader.initWebApplicationContext(ContextLoader.java:205) - Context initialization failed org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.scheduling.quartz.SchedulerFactoryBean' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Invocation of init method failed; nested exception is org.quartz.SchedulerException: Registration of jobs and triggers failed: closeResultSet Caused by: org.quartz.SchedulerException: Registration of jobs and triggers failed: closeResultSet at org.springframework.scheduling.quartz.SchedulerFactoryBean.registerJobsAndTriggers(SchedulerFactoryBean.java:798) 请前辈指点一二，叩谢
啊，前辈，刚才那个问题莫名其妙就没了。现在是另外一个问题，我的xml定义的contrigger是这样的： 在applicationContext.xml里：
然后在具体模块的xml里定义了： 现在的问题是，当weblogic server起来后，报： 2008-10-08 16:40:00,107 org.quartz.core.JobRunShell.run(JobRunShell.java:202) - Calling execute on job DEFAULT.com.foss.main.customObject.MyMethodInvokingJobD etailFactoryBean#308737 2008-10-08 16:40:00,117 org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean$MethodInvokingJob.executeInternal(MethodInvokingJobDetailFact oryBean.java:242) - Could not invoke method 'null' on target object [null] java.lang.IllegalStateException: prepare() must be called prior to invoke() on MethodInvoker at org.springframework.util.MethodInvoker.invoke(MethodInvoker.java:267) at org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean$MethodInvokingJob.executeInternal(MethodInvokingJobDetailFactoryBean.java: 224) at org.springframework.scheduling.quartz.QuartzJobBean.execute(QuartzJobBean.java:86) at org.quartz.core.JobRunShell.run(JobRunShell.java:203) at org.quartz.simpl.SimpleThreadPool$WorkerThread.run(SimpleThreadPool.java:520) 2008-10-08 16:40:00,157 org.quartz.core.JobRunShell.run(JobRunShell.java:208) - Job DEFAULT.com.foss.main.customObject.MyMethodInvokingJobDetailFactoryBean#30 8737 threw a JobExecutionException: org.quartz.JobExecutionException: Could not invoke method 'null' on target object [null] [See nested exception: java.lang.IllegalStateException: prepare() mus t be called prior to invoke() on MethodInvoker] 其中，MyMethodInvokingJobDetailFactoryBean是我wripper的MethodInvokingJobDetailFactoryBean 是不是我xml里config的job不对呢？请前辈指教 true 0 0/5 * * * ?
你的错误报：Could not invoke method 'null' on target object [null] ； 说明的你的配置有问题。如果你是要集群环境跑，那就不能用MethodInvokingJobDetailFactoryBean，好像你的MyMethodInvokingJobDetailFactoryBean也是继承这个的。如果不是集群环境，那么用MethodInvokingJobDetailFactoryBean很方便。
如果不是集群环境参考：
大侠，我是要在集群环境跑。我的目的是要在cluster的环境下，同一时间只能有一个app server 跑scheduled 好的一个job， 我做的那个MyMethodInvokingJobDetailFactoryBean的确是继承的MethodInvokingJobDetailFactoryBean，因为MethodInvokingJobDetailFactoryBean不是序列化的。但是我在MyMethodInvokingJobDetailFactoryBean不知道该怎么重写execute（）。。。。。。。 刚才又去试了你给的SysScheduleManagerImpl.java，可是在做ContextUtil的遇到路径问题。在我的applicationContext里，有定义quartz.property的路径：
这个在weblogic parse xml file的时候是工作的。但是当用FileSystemXmlApplicationContext（xml file list）的时候，就找不到了。我要是改成FileSystemXmlApplicationContext能找到的，weblogic parse的时候就找不到了。晕啊
大侠，我终于搞出来了。没有用那个ContextUtil 而是在xml file里面加一句：
applicationContext 然后在SysScheduleManagerImpl.java里： ApplicationContext ctx = (ApplicationContext) context.getScheduler().getContext().get("applicationContext"); Object otargetObject=ctx.getBean(targetObject);
