Spring1.1.1+quartz1.8.6实现集群环境下的定时任务

1.quartz.properties文件：

#============================================================================
# Configure Main Scheduler Properties
#============================================================================
org.quartz.scheduler.instanceName = mapScheduler
#最多只能有3个线程并发
org.quartz.threadPool.threadCount = 3
org.quartz.scheduler.instanceId = AUTO

#============================================================================
# Configure JobStore  配置数据存储的方式
#============================================================================


#所有的Quartz数据,例如Job和Trigger的细节信息被存储在内存（数据库）中。
#org.quartz.jobStore.class = org.quartz.simpl.JDBCJobStore
#org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore

#配置事务。JobStoreTX来让Quartz帮你管理事务（这是最普遍的选择）;使用JobStoreCMT,Quartz就会让应用服务器容器来管理事务
org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX

#如果数据库没有其他指定的代理，那么就试用代理StdJDBCDelegate。
org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate

org.quartz.jobStore.tablePrefix = QRTZ_

org.quartz.jobStore.isClustered = true

2.applicationContext-quartz.xml文件：

    com.sosgps.customized.hbwysh.quartz.PushNoticeJob">

    
        
            com.sosgps.customized.hbwysh.quartz.MyDetailQuartzJobBean
        
        
            
        
    

    
    
        
            
        
        
            0 0 9 * * ?
        
    

    
             class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        quartz.properties" />
        
            
        
        
            
                
            
        
        
    
 

3.在spring-servlet.xml中引入applicationContext-quartz.xml
  

4.配置中用到的几个类：

  MyDetailQuartzJobBean

package com.sosgps.customized.hbwysh.quartz;

import java.lang.reflect.Method;

import org.apache.log4j.Logger;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.context.ApplicationContext;
import org.springframework.scheduling.quartz.QuartzJobBean;

public class MyDetailQuartzJobBean extends QuartzJobBean {

    private static final Logger LOGGER = Logger.getLogger(MyDetailQuartzJobBean.class);

    private String targetObject;
    private String targetMethod;
    private ApplicationContext applicationContext;



    protected void executeInternal(JobExecutionContext context)

    throws JobExecutionException {

        try {
            LOGGER.info("execute [" + targetObject + "] at once>>>>>>");
            Object otargetObject = applicationContext.getBean(targetObject);
            Method m = null;
            try {
                m = otargetObject.getClass().getMethod(targetMethod, new Class[] {});
                m.invoke(otargetObject, new Object[] {});
            } catch (SecurityException e) {
                LOGGER.error(e);
            } catch (NoSuchMethodException e) {
                LOGGER.error(e);
            }
        } catch (Exception e) {
            throw new JobExecutionException(e);
        }
    }

    public void setApplicationContext(ApplicationContext applicationContext) {

        this.applicationContext = applicationContext;

    }

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

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

}

  PushNoticeJob

package com.sosgps.customized.hbwysh.quartz;

import java.io.Serializable;
import java.text.DateFormat;
import java.util.ArrayList;
import java.util.Date;
import java.util.HashMap;
import java.util.List;

import org.apache.commons.lang.StringUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;

import com.sosgps.dao.customized.wysw.dao.RefCustomerDeviceService;
import com.sosgps.dao.customized.wysw.vo.RefCustomerDeviceVO;
import com.sosgps.dao.domain.Customer;
import com.sosgps.dao.generator.SEQKey;
import com.sosgps.dao.generator.SeqGenerator;
import com.sosgps.dao.mdm.service.CustomerService;
import com.sosgps.dao.mdm.service.RefEmployeeCustomerService;
import com.sosgps.dao.mdm.service.RefEmployeeDeviceService;
import com.sosgps.push.service.PushService;
import com.sosgps.push.vo.MessageObject;
import com.sosgps.web.util.ReqSession;

public class PushNoticeJob implements Serializable {
    private static final long serialVersionUID = -3364631834467951396L;
    private static int counter = 0;

    private static DateFormat simpleDateFormat = new java.text.SimpleDateFormat("MMdd");

    @Autowired
    private RefEmployeeDeviceService refEmployeeDeviceService;

    @Autowired
    private RefEmployeeCustomerService refEmployeeCustomerService;

    @Autowired
    private RefCustomerDeviceService refCustomerDeviceService;

    @Autowired
    private SeqGenerator seqGenerator;

    @Autowired
    @Qualifier("pushService")
    private PushService pushService;

    public void execute() {

    //具体执行方法       

    }

    /**
     * 组装map值
     *
     * @param map
     * @param customerCode
     * @param listValue
     */
    private void generateMapValue(HashMap> map, String customerCode,
            String listValue) {
        if (map.containsKey(customerCode)) {
            List list = map.get(customerCode);
            list.add(listValue);
        } else {
            List list = new ArrayList();
            list.add(listValue);
            map.put(customerCode, list);
        }

    }
}

5.最后启动服务之前，准备好数据库，在quartz1.8.6文档中找到相应数据库的sql，如tables_oracle.sql，创建好相应的表即可。
