Quartzで複数のジョブを実行する例
この例では、Quartz API、Quartz XML、Springを介して複数のQuartzジョブを宣言する方法を示します。 Quartzスケジューラフレームワークでは、各ジョブは一意のトリガーに接続され、スケジューラーによって実行されます。
P.S In Quartz, one trigger for multiple jobs is not possible. （これが間違っている場合は修正してください。）
1. Quartz API
Quartzの3つのジョブ、JobA、Job、およびJobSを作成します。
package com.example.quartz;
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
public class JobA implements Job {
@Override
public void execute(JobExecutionContext context)
throws JobExecutionException {
System.out.println("Job A is runing");
}
}
package com.example.quartz;
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
public class JobB implements Job {
@Override
public void execute(JobExecutionContext context)
throws JobExecutionException {
System.out.println("Job B is runing");
}
}
package com.example.quartz;
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
public class JobC implements Job {
@Override
public void execute(JobExecutionContext context)
throws JobExecutionException {
System.out.println("Job C is runing");
}
}
Quartz APIを使用して、3つの特定のトリガーに割り当てられた3つ以上のジョブを宣言し、スケジュールします。
package com.example.quartz;
import org.quartz.CronScheduleBuilder;
import org.quartz.JobBuilder;
import org.quartz.JobDetail;
import org.quartz.JobKey;
import org.quartz.Scheduler;
import org.quartz.Trigger;
import org.quartz.TriggerBuilder;
import org.quartz.impl.StdSchedulerFactory;
public class CronTriggerExample {
public static void main( String[] args ) throws Exception
{
JobKey jobKeyA = new JobKey("jobA", "group1");
JobDetail jobA = JobBuilder.newJob(JobA.class)
.withIdentity(jobKeyA).build();
JobKey jobKeyB = new JobKey("jobB", "group1");
JobDetail jobB = JobBuilder.newJob(JobB.class)
.withIdentity(jobKeyB).build();
JobKey jobKeyC = new JobKey("jobC", "group1");
JobDetail jobC = JobBuilder.newJob(JobC.class)
.withIdentity(jobKeyC).build();
Trigger trigger1 = TriggerBuilder
.newTrigger()
.withIdentity("dummyTriggerName1", "group1")
.withSchedule(
CronScheduleBuilder.cronSchedule("0/5 * * * * ?"))
.build();
Trigger trigger2 = TriggerBuilder
.newTrigger()
.withIdentity("dummyTriggerName2", "group1")
.withSchedule(
CronScheduleBuilder.cronSchedule("0/5 * * * * ?"))
.build();
Trigger trigger3 = TriggerBuilder
.newTrigger()
.withIdentity("dummyTriggerName3", "group1")
.withSchedule(
CronScheduleBuilder.cronSchedule("0/5 * * * * ?"))
.build();
Scheduler scheduler = new StdSchedulerFactory().getScheduler();
scheduler.start();
scheduler.scheduleJob(jobA, trigger1);
scheduler.scheduleJob(jobB, trigger2);
scheduler.scheduleJob(jobC, trigger3);
}
}
出力
Job A is runing //every 5 seconds Job B is runing Job C is runing Job A is runing //every 5 seconds Job B is runing Job C is runing
2. Quartz XMLの例
XMLファイルの同等のバージョン。 「quartz.properties」と「quartz-config.xml」がプロジェクトのクラスパスにあることを確認してください。
ファイル–quartz.properties
org.quartz.scheduler.instanceName = MyScheduler org.quartz.threadPool.threadCount = 3 org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore org.quartz.plugin.jobInitializer.class =org.quartz.plugins.xml.XMLSchedulingDataProcessorPlugin org.quartz.plugin.jobInitializer.fileNames = quartz-config.xml org.quartz.plugin.jobInitializer.failOnFileNotFound = true
ファイル–quartz-config.xml
JobA GroupDummy This is Job A com.example.quartz.JobA dummyTriggerNameA JobA GroupDummy 0/5 * * * * ? JobB GroupDummy This is Job B com.example.quartz.JobB dummyTriggerNameB JobB GroupDummy 0/5 * * * * ?
ファイル：web.xml
org.quartz.ee.servlet.QuartzInitializerListener
3. 春の例
Springの同等バージョン。
package com.example.job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.scheduling.quartz.QuartzJobBean;
public class JobA extends QuartzJobBean {
@Override
protected void executeInternal(JobExecutionContext arg0)
throws JobExecutionException {
System.out.println("Job A is runing");
}
}
package com.example.job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.scheduling.quartz.QuartzJobBean;
public class JobB extends QuartzJobBean {
@Override
protected void executeInternal(JobExecutionContext arg0)
throws JobExecutionException {
System.out.println("Job B is runing");
}
}
package com.example.job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.scheduling.quartz.QuartzJobBean;
public class JobC extends QuartzJobBean {
@Override
protected void executeInternal(JobExecutionContext arg0)
throws JobExecutionException {
System.out.println("Job C is runing");
}
}
File : Spring-Quartz.xml – Spring XMLBean構成ファイルでジョブとトリガーを宣言します。
それを実行します
package com.example.common;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class App {
public static void main(String[] args) throws Exception {
new ClassPathXmlApplicationContext("Spring-Quartz.xml");
}
}
出力。
