Java Spring批处理自定义编写器关闭方法被调用两次（需要特殊处理）

java spring spring-batch

Java Spring批处理自定义编写器关闭方法被调用两次（需要特殊处理）,java,spring,spring-batch,Java,Spring,Spring Batch,我有以下writer类原型： public class MyWriter extends AbstractItemStreamItemWriter<FieldSet> { ... @Override public void close() { ... { ... } 作业是从MQ侦听器触发的，如下所示： @Autowired private Job job; @Autowired private JobLaunche

我有以下writer类原型：

public class MyWriter extends AbstractItemStreamItemWriter<FieldSet> {
    ...
    @Override
    public void close()
    {
        ...
    {
    ...
}
作业是从MQ侦听器触发的，如下所示：

@Autowired
private Job job;

@Autowired
private JobLauncher jobLauncher;

@JmsListener(destination = "queue_name")
public void receiveMessage(TextMessage message) throws JMSException
{
    log.warn("Received message {} with listener {}.", message, this);

    JobParametersBuilder jobParametersBuilder = new JobParametersBuilder();

    // add job parameters here
    ...

    JobParameters jobParameters = jobParametersBuilder.toJobParameters();

    try
    {
        JobExecution jobExecution = jobLauncher.run(job, jobParameters);
        log.trace("jobExecution = " + jobExecution);
    }
    catch (JobExecutionException jee)
    {
        log.warn("Could not run job {}", job);
    }
}
我遇到的问题是MyWriter的close方法被调用了两次。每个调用的堆栈跟踪是：
