Quartz2-Quartz与tomcat集成

Quartz2-Quartz与tomcat集成

　　Quartz只与tomcat简单集成，不用其他框架。

• 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>

         <load-on-startup>1</load-on-startup>
     </servlet>
