Quartz JOBを動的に定義するユーザーインターフェイスを公開したい。ユーザーは、JOB名、cron式、時間間隔などのJOBプロパティを定義する機能を持つ必要があります。特定のJavaタスクなどのクラス.
この機能を促進するオープンソースはありますか?または、動的なQuartzスケジューラ用に独自のモジュールを作成する場合、その方法は何ですか?
動的Quartz JOBスケジューリングのコード例:

タスクのJavaクラス
package com.xxx.example.dynamicjob;
public class MyTask
{
public void performAction() {
System.out.println("Hey, you reached me...:)");
}
}
動的ジョブを作成するJavaクラス
package com.xxx.example.dynamicjob;
import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.core.io.ClassPathResource;
import org.springframework.scheduling.quartz.CronTriggerBean;
import org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean;
public class DynamicJobExample {
/**
* @param args
*/
public static void main(String[] args) {
ClassPathResource res = new ClassPathResource("dynamic-jobs.xml");
XmlBeanFactory factory = new XmlBeanFactory(res);
//get the quartzFactory bean
Scheduler scheduler = (Scheduler) factory.getBean("scheduler");
//get the task bean
MyTask myTask = (MyTask) factory.getBean("myTask");
try {
// create JOB
MethodInvokingJobDetailFactoryBean jobDetail = new MethodInvokingJobDetailFactoryBean();
jobDetail.setTargetObject(myTask);
jobDetail.setTargetMethod("performAction");
jobDetail.setName("MyJobDetail");
jobDetail.setConcurrent(false);
jobDetail.afterPropertiesSet();
/* SimpleTriggerBean trigger = new SimpleTriggerBean();
trigger.setBeanName("MyTrigger");
trigger.setJobDetail((JobDetail) jobDetail.getObject());
trigger.setRepeatInterval(5000);
trigger.afterPropertiesSet();
*/
// create CRON Trigger
CronTriggerBean cronTrigger = new CronTriggerBean();
cronTrigger.setBeanName("CRON0001");
// Execute after each 5 second
String expression = "5 * * * * ?";
cronTrigger.setCronExpression(expression);
cronTrigger.afterPropertiesSet();
//scheduler.scheduleJob(jobDetail, cronTrigger);
scheduler.scheduleJob((JobDetail) jobDetail.getObject(), cronTrigger);
// Start Scheduler
scheduler.start();
} catch (Exception e) {
e.printStackTrace();
}
}
}
Spring 4では、これを問題なく行うことができます(Quartz 2.0)-spring-dispatcher-servlet.xml
<task:annotation-driven executor="myExecutor" scheduler="myScheduler"/>
<task:scheduler id="myScheduler" pool-size="10"/>
<task:executor id="myExecutor" pool-size="1"/>
上記で作成したBeanをSpring BeanまたはService Classに注入します
@Service
public class DynamicJobExample {
@Autowired
@Qualifier("myScheduler")
private TaskScheduler scheduler;
public void schedule() throws ParseException {
scheduler.schedule(new MyTask(), new CronTrigger("5 * * * * ?"));
}
}
MyTaskは実行可能なクラスでなければなりません
public class MyTask implements Runnable{
@Override
public void run() {
System.out.println("Hey, you reached me...:)");
}
}
Mavenの依存関係は(pom.xml)
<spring.version>4.1.0.RELEASE</spring.version>
<dependency>
<groupId>org.quartz-scheduler</groupId>
<artifactId>quartz</artifactId>
<version>2.2.1</version>
</dependency>
この方法でもJobDetailおよびTriggerオブジェクトを作成できます。
JobDetail jobDetail;
String myJobClass = "com.MyJobClass";
String myJobName = "myJobName";
String myJobGroup ="myJobGroup";
Class myJobClassType= Class.forName(myJobClass);
jobDetail =JobBuilder.newJob().ofType(myJobClassType)
.withIdentity(myJobName, myJobGroup).build();
String myGroup = "myGroup";
String name = "TriggerName";
String expresion = "5 * * * * ?";
Trigger trigger = TriggerBuilder
.newTrigger()
.withIdentity(name, myGroup)
.withSchedule(
CronScheduleBuilder.cronSchedule(expresion))
.build();
package com.myproject;
import Java.text.ParseException;
import org.quartz.JobBuilder;
import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.quartz.SchedulerFactory;
import org.quartz.impl.triggers.CronTriggerImpl;
import org.springframework.stereotype.Component;
@Component
public class QuartzSchedulerExample {
public QuartzSchedulerExample() {
SchedulerFactory schedFact = new org.quartz.impl.StdSchedulerFactory();
Scheduler scheduler;
try {
scheduler = schedFact.getScheduler();
JobDetail details = JobBuilder.newJob(MyMailBean.class)
.withDescription("something")
.withIdentity("mejob","myGroup")
.storeDurably(true).build();
CronTriggerImpl trigger = new CronTriggerImpl();
trigger.setName("T1");
try {
trigger.setCronExpression("0 0 0 * * ? *");
} catch (ParseException e) {
e.printStackTrace();
}
trigger.setDescription("desc");
scheduler.scheduleJob(details,trigger);
scheduler.start();
} catch (SchedulerException e) {
e.printStackTrace();
}
}
}
ジョブは毎日00:00:00(時間:分:秒)実行されます
