quartz在tomcat下配置使用

LXY3800

• 写一个要需要执行任务的类DumbJob，实现Job接口
  

package com.lll;
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
public class DumbJob implements Job {
public void execute(JobExecutionContext arg0) throws JobExecutionException {
System.err.println("DumbJob is executing.");
}
}

• 建两个配置文件quartz.properties和quartz_job.xml，放在classes下
  
• quartz.properties
  

org.quartz.scheduler.instanceName = TestScheduler
org.quartz.scheduler.instanceId = one
org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount = 2
org.quartz.threadPool.threadPriority = 4
org.quartz.plugin.triggHistory.class = org.quartz.plugins.history.LoggingTriggerHistoryPlugin
org.quartz.plugin.triggHistory.triggerFiredMessage = Trigger {1}.{0} fired job {6}.{5} at: {4, date, HH:mm:ss MM/dd/yyyy}
org.quartz.plugin.triggHistory.triggerCompleteMessage = Trigger {1}.{0} completed firing job {6}.{5} at {4, date, HH:mm:ss MM/dd/yyyy} with resulting trigger instruction code: {9}
org.quartz.plugin.jobInitializer.class = org.quartz.plugins.xml.JobInitializationPlugin
org.quartz.plugin.jobInitializer.fileName = quartz_job.xml
org.quartz.plugin.jobInitializer.overWriteExistingJobs = false
org.quartz.plugin.jobInitializer.failOnFileNotFound = true
org.quartz.plugin.shutdownhook.class = org.quartz.plugins.management.ShutdownHookPlugin
org.quartz.plugin.shutdownhook.cleanShutdown = true

• quartz_job.xml
  

<?xml version="1.0" encoding="UTF-8"?>
<quartz>
<job>
<job-detail>
<name>helloworld</name>
<group>group1</group>
<job-class>com.lll.DumbJob</job-class>
</job-detail>
<trigger>
<cron>
<name>test</name>
<group>group1</group>
<job-name>helloworld</job-name>
<job-group>group1</job-group>
<cron-expression>0/1 * * * * ?</cron-expression>
</cron>
</trigger>
</job>
</quartz>

• 配置web.xml
  

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4"
xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.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>

　　quartz.jar见附件，启动tomcat在控制台可看到打印的结果
