quarzt-2.1.5 java版

quartz-2.1.5示例：

1、下载quartz

2、解压后将lib中的jar包、jta.jar和quartz-all-2.1.5.jar导入

3、编写job

package com.test;

import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class DemoJob implements Job{
	static Logger logger = LoggerFactory.getLogger(DemoJob.class);

	public DemoJob() {
	}

	public void execute(JobExecutionContext context)
			throws JobExecutionException {
		logger.info("=========执行==================");
	}
}

 4、导入log4j.xml和编写配置文件

  导入log4j.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">

  <appender name="default" class="org.apache.log4j.ConsoleAppender">
    <param name="target" value="System.out"/>
    <layout class="org.apache.log4j.PatternLayout">
      <param name="ConversionPattern" value="[%p] %d{dd MMM hh:mm:ss.SSS aa} %t [%c]%n%m%n%n"/>
    </layout>
  </appender>


 <logger name="org.quartz">
   <level value="info" />
 </logger>

  <root>
    <level value="info" />
    <appender-ref ref="default" />
  </root>

  
</log4j:configuration>

  编写quartz.properties

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

#Configure Main Scheduler Properties        

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

org.quartz.scheduler.instanceName = QuartzScheduler          

org.quartz.scheduler.instanceId = AUTO        

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

#Configure ThreadPool        

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

org.quartz.threadPool.threadCount = 5          

org.quartz.threadPool.threadPriority = 5          

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

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

#Configure JobStore        

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

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

#Configure Plugins        

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

org.quartz.plugin.jobInitializer.class = org.quartz.plugins.xml.XMLSchedulingDataProcessorPlugin          

org.quartz.plugin.jobInitializer.fileNames =jobs.xml      

org.quartz.plugin.jobInitializer.failOnFileNotFound =true

5、编写jobs.xml

<?xml version="1.0" encoding="UTF-8"?>
<job-scheduling-data
	xmlns="http://www.quartz-scheduler.org/xml/JobSchedulingData"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.quartz-scheduler.org/xml/JobSchedulingData http://www.quartz-scheduler.org/xml/job_scheduling_data_1_8.xsd"
	version="1.8">
	<schedule>
		<job>
			<name>DemoJob</name>
			<group>DEFAULT</group>
			<description>A job just for test</description>
			<job-class>com.test.DemoJob</job-class>
		</job>
		<trigger>
			<!-- <simple>
				<name>HeiTrigger</name>
				<group>DEFAULT</group>
				<job-name>DemoJob</job-name>
				<job-group>DEFAULT</job-group>
				<repeat-count>-1</repeat-count>
				<repeat-interval>10000</repeat-interval>
				</simple> -->

			<cron>
				<name>Trigger</name>
				<group>DEFAULT</group>
				<job-name>DemoJob</job-name>
				<job-group>DEFAULT</job-group>
				<cron-expression>0 11 17 * * ?</cron-expression>
			</cron>
		</trigger>
	</schedule>
</job-scheduling-data>

   有两种模式：一种是每个多久执行任务，如上面是10秒，执行次数为无限次。二种是每天在什么时候执行任务，上面代码表示的是每天下午5点11分执行任务。

6、编写DemoSchedular.javapackage com.test;

import java.util.Date;

import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.quartz.SchedulerFactory;
import org.quartz.impl.StdSchedulerFactory;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class DemoSchedular {
	static Logger logger = LoggerFactory.getLogger(DemoSchedular.class);

	public void test() {
		try {
			SchedulerFactory schedulerFactory = new StdSchedulerFactory();
			Scheduler scheduler = schedulerFactory.getScheduler();
			scheduler.start();
			logger.info("==========started at " + new Date() + "==========");
		} catch (SchedulerException e) {
			e.printStackTrace();
		}
	}
	public static void main(String[] args) {
		DemoSchedular demoSchedular = new DemoSchedular();
		demoSchedular.test();
	}
}
