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 trigger 

persistence 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' defined 

in 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 insertion 

into 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]

类路径上的quartz.properties：

创建数据库表结构：在下载的包quartz-1.5.2.zip\quartz-1.5.2\docs\dbTables\tables_oracle.sql

调度类，SysScheduleManagerImpl.java:

package com.sunrise.psmis.sysmanagement.service.impl;

import java.lang.reflect.Method;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.context.ApplicationContext;
import org.springframework.scheduling.quartz.QuartzJobBean;

import com.sunrise.psmis.webapp.util.ContextUtil;

public class SysScheduleManagerImpl extends QuartzJobBean{
 protected final Log logger = LogFactory.getLog(getClass());
 
 private String targetObject;
 private String targetMethod;
 
 protected void executeInternal(JobExecutionContext context) throws JobExecutionException{
 //  System.out.println(jobData.getData() + " 第一个已经被执行了！！");
  try
  {
         ApplicationContext ctx =ContextUtil.getContext();

         Object otargetObject=ctx.getBean(targetObject);
   
   Method m=null;
   try {
    m = otargetObject.getClass().getMethod(targetMethod, new Class[] {});
    
    m.invoke(otargetObject,  new Object[] {});
   } catch (SecurityException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   } catch (NoSuchMethodException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   }
         

  }
  catch(Exception e)
  {
   throw new JobExecutionException(e);
  }
  finally
  {
   logger.debug("end");
  }
  
 }

 public void setTargetObject(String targetObject) {
  this.targetObject = targetObject;
 }

 public void setTargetMethod(String targetMethod) {
  this.targetMethod = targetMethod;
 }

}

//ContextUtil类可以在应用启动的Listener里初始化Spring的ApplicationContext，将ApplicationContext保存在static变量里
