Bonjour Tout le monde,

Voilé je suis débutante avec scheduler et mon problème est le suivant:

j'aimerai scheduler un batch et surtout pouvoir traiter la politique de reprise, c'est à dire quand le job echou pouvoir relancer ce dernier autant de fois qui lui est permi, et pour ce faire j'ai lu des cours qui conseillé d'introduire un jobListener chose que j'ai faite mais sa n'a rien donné.
Voici ce que j'ai fait:

Tout d'abord j'ai introduit cette ligne dans le fichier xml de scheduler:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
4
5
6
7
8
9
 
<!-- *************************************************************** -->
 	<!-- Declare a job listener that will take care of job retries, etc. -->
 	<!-- *************************************************************** -->
 
 <bean id="myJobListener" class="org.quartz.JobListener">
         <property name="name" value="myJobListener"/>
         <property name="jobDetail" ref="myJobListener"></property>
     </bean>

ensuite j'ai créer la callse du joblistener qui est la suivante:

Code :

 package com.scheduler.listener;
 
 import org.quartz.JobDetail;
 import org.quartz.JobExecutionContext;
 import org.quartz.JobExecutionException;
 import org.quartz.JobListener;
 import org.springframework.batch.core.JobExecution;
 
 public class UnJobListener implements JobListener {
 	public static final String LISTENER_NAME = "dummyJobListenerName";
 
 	public UnJobListener() {
 		// TODO Auto-generated constructor stub
 	}
 
 	@Override
 	public String getName() {
 		// TODO Auto-generated method stub
 		return LISTENER_NAME;
 	}
 
 	@Override
 	// Run this if job is about to be executed.
 	public void jobToBeExecuted(JobExecutionContext context) {
 		// TODO Auto-generated method stub
 		String jobName = context.getJobDetail().getKey().toString();
 		System.out.println("jobToBeExecuted");
 		System.out.println("Job : " + jobName + " is going to start...");
 		 //JobDetail jobDetail = context.getJobDetail();
 //         MyJobDetail myJobDetail = (MyJobDetail) jobDetail;          
 //         jobDetail.getJobDataMap().put("MessageAdded", myJobDetail.getMyMessage());
 
 
 
 	}
 
 
 	@Override
 	public void jobExecutionVetoed(JobExecutionContext context) {
 		// TODO Auto-generated method stub
        System.out.println("jobExecutionVetoed");
 	}
 
 	@Override
 	public void jobWasExecuted(JobExecutionContext context,
 			JobExecutionException jobException) {
 		// TODO Auto-generated method stub
 		System.out.println("jobWasExecuted");
 
 		String jobName = context.getJobDetail().getKey().toString();
 		System.out.println("Job : " + jobName + " is finished...");
 
 		if (!jobException.getMessage().equals("")) {
 			System.out.println("Exception thrown by: " + jobName
 				+ " Exception: " + jobException.getMessage());
 		}
 	}
 
 }

mais celà n'a pas marché et sa me génère celà:

Merci à vous

j'ai corrigé une erreure que j'ai comise concernanat la class où j'ai mis une interface (résultat d'un copier/coller).
Maintenanat j'ai une autre erreure qui est sachant que j'ai modifié ainsi :

<bean id="myJobListener" class="com.prosodie.nca.scheduler.MyJobListener">
<property name="name" value="UnJobListener"/>
</bean>
