java War部署在执行作业时创建的多个类实例

Question

我有一个使用quartz执行计划作业的web应用程序。我在嵌入式eclipse tomcat中进行开发，当一个作业必须执行时，它只执行一次，但当我创建一个简单的war并部署在jboss中时，触发器执行有一个奇怪的行为，名为（job）的类同时执行两次，我检查了日志和执行调用，它只执行了一次

2014-12-30 11:25:30,003 [org.springframework.scheduling.quartz.SchedulerFactoryBean#0_Worker-1] DEBUG [org.quartz.core.JobRunShell] - Calling execute on job DEFAULT.JobListener

但该方法执行了两次

2014-12-30 11:25:30,003 [org.springframework.scheduling.quartz.SchedulerFactoryBean#0_Worker-1] DEBUG [com.xxx.imides.batch.exec.JobListener] - executeInternal 
2014-12-30 11:25:30,003 [org.springframework.scheduling.quartz.SchedulerFactoryBean#0_Worker-1] DEBUG [com.indra.xxx.batch.exec.JobListener] - executeInternal 
 2014-12-30 11:25:30,004 [org.springframework.scheduling.quartz.SchedulerFactoryBean#0_Worker-1] DEBUG [com.indra.xxx.batch.exec.JobListener] - hashCode 20730000
2014-12-30 11:25:30,004 [org.springframework.scheduling.quartz.SchedulerFactoryBean#0_Worker-1] DEBUG [com.indra.xxx.batch.exec.JobListener] - hashCode 20730000

经过大量的测试和研究，我完全迷路了，我不知道该去哪里找，找什么。知道吗

以下是应用程序配置：

网络。xml——我在所有东西之间都有这个

<!-- Creates the Spring Container shared by all Servlets and Filters -->
 <listener> 
     <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 
 </listener> 

JobListener。爪哇

public class JobListener extends QuartzJobBean{
....
    @Override
    protected void executeInternal(JobExecutionContext context)
            throws JobExecutionException {

        if(logger.isDebugEnabled()){
            logger.debug("executeInternal ");
            logger.debug("jobRunTime " + context.getJobRunTime());
            logger.debug("toString " + context.getJobDetail().toString());
            logger.debug("hashCode " + context.getJobInstance().hashCode());

        }  
        pickUpChanges();

    }
}
