1、所需要的jar文件

2、web.xml配置

<servlet>
       <servlet-name>QuartzInitializer</servlet-name>
       <servlet-class>org.quartz.ee.servlet.QuartzInitializerServlet</servlet-class>
       <init-param>
           <param-name>config-file</param-name>
           <param-value>quartz.properties</param-value>
       </init-param>
       <init-param>
           <param-name>shutdown-on-unload</param-name>
           <param-value>true</param-value>
       </init-param>
       <init-param>
           <param-name>wait-on-shutdown</param-name>
           <param-value>true</param-value>
       </init-param>
       <init-param>
           <param-name>start-scheduler-on-load</param-name>
           <param-value>true</param-value>
       </init-param>
       <load-on-startup>1</load-on-startup>
   </servlet>

3、Job实现类

import java.util.Date;
import java.util.List;
import java.util.concurrent.locks.Lock;
import java.util.concurrent.locks.ReentrantLock;

import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import com.ewa.analyzer.luenceapi.CreateIndexImpl;
import com.ewa.bean.WorksBean;
import com.ewa.bean.dao.WorksDAO;

public class _CCJob implements Job {
   private static Logger _log = LoggerFactory.getLogger(CreateIndexJob.class);
   private UserDao ud = null;

   public _CCJob() {

ud = new UserDAO();

    }

   public void execute(JobExecutionContext context) {
       final Lock lock = new ReentrantLock();
       new Thread() {
           public void run() {
               lock.lock();
               try {
                   _log.info("execute quartz job " + new Date());
                   System.out.println("execute quartz job " + new Date());

                   List<User> userList = ud.getAllUsers();
                   new CreateUserImpl<User>().createIndex(userList,
                           User.class);
                   _log.info("job executing finish");
                   System.out.println("job executing finish");
               } catch (Exception e) {
                   _log.info("execute job errors");
                   System.out.println("execute job errors");
                   if (e.getMessage() != null) {
                       _log.info("errors details : " + e.getMessage());
                       System.out.println("errors details : " + e.getMessage());
                   }
               } finally {
                   lock.unlock();
               }
           }
       }.start();
   }
}

4、

source目录下quartz.properties定义

#============================================================================
# Configure Main Scheduler Properties
#============================================================================
org.quartz.scheduler.instanceName = QuartzScheduler
#============================================================================
# Configure ThreadPool
#============================================================================
org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount = 5
#============================================================================
# Configure xml Plugins
#============================================================================
org.quartz.plugin.jobInitializer.class = org.quartz.plugins.xml.XMLSchedulingDataProcessorPlugin
org.quartz.plugin.jobInitializer.fileNames = quartz_jobs.xml
org.quartz.plugin.jobInitializer.failOnFileNotFound = true
org.quartz.plugin.jobInitializer.scanInterval = 30000
org.quartz.plugin.jobInitializer.wrapInUserTransaction = false

5、source目录下quartz_jobs.xml定义

<?xml version='1.0' encoding='utf-8'?>
<job-scheduling-data
   xmlns="http://www.quartz-scheduler.org/xml/JobSchedulingData"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://www.quartz-scheduler.org/xml/JobSchedulingData http://www.quartz-scheduler.org/xml/job_scheduling_data_1_8.xsd"
   version="1.8">
   <schedule>
       <job>
           <name>c_CCJob</name>
           <group>firefox</group>
           <description>The job description</description>
           <job-class>_CCJob</job-class>
       </job>

       <trigger>
           <cron>
               <name>my-trigger</name>
               <group>firefox</group>
               <job-name>c_CCJob</job-name>
               <job-group>firefox</job-group>
               
               <cron-expression>0 0 0 * * ?</cron-expression>
           </cron>
       </trigger>
   </schedule>
</job-scheduling-data>
