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!
