quartzの導入メモ

メモ。基本QUARTZ QUICK STARTを見てやっただけ。

1.quartzのダウンロード
quartz

2.ダウンロードしたファイルを解凍してlibにquartz-2.1.6.jarをぶっこむ

3.quartz.propertiesを作成する。
(WEB-INF/classes以下のどっかに配備されるようにしとく)
内容は

org.quartz.scheduler.instanceName = MyScheduler

org.quartz.threadPool.threadCount = 3

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

4.Javaから呼び出してみる

QuartzTest.java

package hoge.scheduler;

import org.quartz.JobDetail;

import org.quartz.Scheduler;

import org.quartz.Trigger;

import org.quartz.impl.StdSchedulerFactory;

import static org.quartz.JobBuilder.*;

import static org.quartz.TriggerBuilder.*;

import static org.quartz.SimpleScheduleBuilder.*;

public class QuartzTest {

/**

* @param args

public static void main(String[] args) {

try {

// Grab the Scheduler instance from the Factory

Scheduler scheduler = StdSchedulerFactory.getDefaultScheduler();

// and start it off

scheduler.start();

System.out.println("START");

// define the job and tie it to our HelloJob class

JobDetail job = newJob(HelloJob.class)

.withIdentity("job1", "group1")

.build();

// Trigger the job to run now, and then repeat every 40 seconds

Trigger trigger = newTrigger()

.withIdentity("trigger1", "group1")

.startNow()

.withSchedule(simpleSchedule()

.withIntervalInSeconds(10)

.repeatForever())

.build();

// Tell quartz to schedule the job using our trigger

scheduler.scheduleJob(job, trigger);

Thread.sleep(11000);

scheduler.shutdown();

System.out.println("END");

} catch (Exception e) {

System.out.println(e.getMessage());

}

HelloJob.java

package hoge.scheduler;

import org.quartz.Job;

import org.quartz.JobExecutionContext;

import org.quartz.JobExecutionException;

public class HelloJob implements Job {

@Override

public void execute(JobExecutionContext arg0) throws JobExecutionException {

System.out.println("HOGE");

}

QuartzTest.javaの実行結果

START

HOGE

END
