Beispiel zum Ausführen mehrerer Jobs in Quartz
In diesem Beispiel zeigen wir Ihnen, wie Sie mehrere Quarzjobs über Quarz-APIs, Quarz-XML und Spring deklarieren. Im Quartz Scheduler-Framework wird jeder Job an einen eindeutigen Trigger angehängt und vom Scheduler ausgeführt.
P.S In Quartz, one trigger for multiple jobs is not possible. (Korrigieren Sie mich, wenn dies falsch ist.)
1. Quarz-APIs
Erstellen Sie die Jobs von 3 Quartz, JobA, JobB und JobC.
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");
}
}
Verwenden Sie Quarz-APIs, um mehr als 3 Jobs zu deklarieren, die 3 bestimmten Triggern zugewiesen sind, und planen Sie sie.
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);
}
}
Ausgabe
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. Quarz-XML-Beispiel
Die entsprechende Version in der XML-Datei. Stellen Sie sicher, dass sich "quartz.properties" und "quartz-config.xml" im Projektklassenpfad befinden.
Datei - 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
Datei - 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 * * * * ?
Datei: web.xml
org.quartz.ee.servlet.QuartzInitializerListener
3. Frühlingsbeispiel
Die entsprechende Version im Frühjahr.
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 - Deklariert Jobs und Trigger in der Spring XML Bean-Konfigurationsdatei.
Starte es
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");
}
}
Ausgabe.
