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 = QuartzSchedulerorg.quartz.scheduler.instanceId = AUTO#============================================================================# Configure ThreadPool #============================================================================org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPoolorg.quartz.threadPool.threadCount = 5org.quartz.threadPool.threadPriority = 5#============================================================================# Configure JobStore #============================================================================org.quartz.jobStore.misfireThreshold = 60000org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore#============================================================================# Configure Plugins #============================================================================org.quartz.plugin.triggHistory.class = org.quartz.plugins.history.LoggingJobHistoryPluginorg.quartz.plugin.jobInitializer.class = org.quartz.plugins.xml.JobInitializationPluginorg.quartz.plugin.jobInitializer.fileNames = jobs.xmlorg.quartz.plugin.jobInitializer.overWriteExistingJobs = trueorg.quartz.plugin.jobInitializer.failOnFileNotFound = trueorg.quartz.plugin.jobInitializer.scanInterval = 10org.quartz.plugin.jobInitializer.wrapInUserTransaction = false
?3、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！
