spring批处理限制跨多个服务器的单个作业实例

我实现了一个监听器,它检查与某个名称匹配的spring批处理控制表中正在运行的作业执行数。如果执行的大小超过1,则当前作业的作业执行将失败。代码如下:

@Component
public class SingleInstanceListener implements JobExecutionListener {
    @Autowired
    private JobExplorer explorer;

    @Override
    public void beforeJob(JobExecution jobExecution) {
        String jobName = jobExecution.getJobInstance().getJobName();
        Set<JobExecution> executions = explorer.findRunningJobExecutions(jobName);
        if(executions.size() > 1) {
            jobExecution.stop();
        }
    }

    @Override
    public void afterJob(JobExecution jobExecution) {

    }

}
