quartz例子

在quartz中一个作业实例必须实现org.quartz.Job接口
如:

13811151870

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/
