WEB中使用quartz框架来实现任务的自动处理
1、下载quartz的相应版本（本机是quartz-1.6.5)，解压后将quartz-1.6.5.jar以及lib中各个子目录中的jar包加入到工程的lib中，其中有些jar不是必须的，取决于你要使用的功能。
2、编写quartz.properties 文件。
#============================================================================ # Configure Main Scheduler Properties #============================================================================ org.quartz.scheduler.instanceName = QuartzScheduler org.quartz.scheduler.instanceId = AUTO #============================================================================ # Configure ThreadPool #============================================================================ org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool org.quartz.threadPool.threadCount = 5 org.quartz.threadPool.threadPriority = 5 #============================================================================ # Configure JobStore #============================================================================ org.quartz.jobStore.misfireThreshold = 60000 org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore #============================================================================ # Configure Plugins #============================================================================ org.quartz.plugin.triggHistory.class = org.quartz.plugins.history.LoggingJobHistoryPlugin org.quartz.plugin.jobInitializer.class = org.quartz.plugins.xml.JobInitializationPlugin org.quartz.plugin.jobInitializer.fileNames = jobs.xml org.quartz.plugin.jobInitializer.overWriteExistingJobs = true org.quartz.plugin.jobInitializer.failOnFileNotFound = true org.quartz.plugin.jobInitializer.scanInterval = 10 org.quartz.plugin.jobInitializer.wrapInUserTransaction = false3、编写jobs.xml文件.
<?xml version='1.0' encoding='utf-8'?>
<quartz xmlns="http://www.opensymphony.com/quartz/JobSchedulingData"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.opensymphony.com/quartz/JobSchedulingData
http://www.opensymphony.com/quartz/xml/job_scheduling_data_1_5.xsd"
version="1.5">
<job>
<job-detail>
<name>HelloWorld</name>
<group>DEFAULT</group>
<description>
A job that just for test
</description>
<job-class>
com.stone.quartz.HelloWorld
</job-class>
<!-- 易变，活泼 -->
<volatility>false</volatility>
<!-- 耐久性 -->
<durability>false</durability>
<!-- 恢复性 -->
<recover>false</recover>
</job-detail>
<trigger>
<simple>
<name>HelloTrigger1</name>
<group>DEFAULT</group>
<job-name>HelloWorld</job-name>
<job-group>DEFAULT</job-group>
<start-time>2011-08-30T07:22:36</start-time>
<!--重复次数 -->
<repeat-count>-1</repeat-count>
<!-- 重复时间间隔 -->
<repeat-interval>10000</repeat-interval>
</simple>
</trigger>
</job>
</quartz>
4、注意以上两个文件的位置，应该位于工程的src目录下，如果是发布好的工程对应在/WEB-INFO/classes下面。
5、修改web.xml增加servlet。
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<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>
<load-on-startup>1</load-on-startup>
</servlet>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
5、编写job类。
package com.stone.quartz;
import java.util.Date;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
public class HelloWorld implements Job {
private static Log logger = LogFactory.getLog(HelloWorld.class);// 日志记录器
public void execute(JobExecutionContext context)
throws JobExecutionException {
logger.info("Hello World! - " + new Date());
}
}
4、发布并访问工程，看看控制台是不是有正确的打印你的内容呢！
