一个非常简单的quartz例子

一个非常简单的quartz例子

在quartz中一个作业实例必须实现org.quartz.Job接口

如:

 

package com.unicom.gdnum.jobs;

 

import java.util.*;

 

import org.apache.commons.logging.*;

import org.quartz.Job;

import org.quartz.JobExecutionContext;

import org.quartz.JobExecutionException;

 

public class HelloworldJob implements Job{

 

 static Log log=LogFactory.getLog(HelloworldJob.class);

 public  HelloworldJob() {

  

 }

 public void execute(JobExecutionContext arg0) throws JobExecutionException {

  // TODO Auto-generated method stub

  log.info("Hello World Quartz......."+(new Date()).toLocaleString());

 }

}

 

 

quartz有自己的配置文个名为quartz.properties，如果我们不在src/（根目录）如果我们不建立文件那么quartz就会使用quartz.jar包里的这个的文件。该文件通常包含以下内容：

 

#

# Configure Main Scheduler Properties 

#

 

org.quartz.scheduler.instanceName = TestScheduler

org.quartz.scheduler.instanceId = AUTO

 

#

# Configure ThreadPool 

#

 

org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool

org.quartz.threadPool.threadCount =  5

org.quartz.threadPool.threadPriority = 4

 

#

# Configure JobStore 

#

 

org.quartz.jobStore.misfireThreshold = 5000

 

org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore

 

# ===========================================================================

# Configure SchedulerPlugins  ===============================================

# ===========================================================================

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

 

以上配置quartz所需的配置，其中org.quartz.plugin.jobInitializer.fileName = /quartz_job.xml指定作业配置文件名，下面我是为HelloworldJob 写的一个配置，quartz_job.xml内容如下：

<?xml version="1.0" encoding="UTF-8"?>

<quartz>

  <job>

    <job-detail>

      <name>helloworld</name>

      <group>group1</group>

      <job-class>com.unicom.gdnum.jobs.HelloworldJob</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 0/1 * * * ?</cron-expression>

     </cron>

    </trigger>

  </job>

</quartz>

 

这是在tomcat中作的一个例子，当然要使用quartz面要下载其相关包!
