Spring Batch Job登录完成

Question

I have a Spring batch job which runs like this:

public void myMethod() throws JobParametersInvalidException, JobExecutionAlreadyRunningException, JobRestartException, JobInstanceAlreadyCompleteException {
    logger.log("Job Starting");

    JobParameters param = new JobParametersBuilder()
            .addString("JobID", String.valueOf(System.currentTimeMillis()))
            .toJobParameters();

    jobLauncher.run(myJob(), param);

    logger.log("Job Finished");
}

This runs asynchronously by using a TaskExecutor . So the second logger.log logs immediately after the job has been called.

I want the logging to log after myJob() has finished.

I have tried changing the actual job to do this but this doesn't seem like the best solution. I also tried looking for methods such as andThen and onComplete but I couldn't find anything.

Is there a way to do this?

You might want to have a look at JobExecutionListener this allows you to do some processing before and after the job execution.

public class DoSomethingAroundJob implements JobExecutionListener {

  public void beforeJob(JobExecution jobExecution) {
      System.out.println("Called beforeJob().");
  }

  public void afterJob(JobExecution jobExecution) {
      System.out.println("Called afterJob().");
  }
}

Then you would need to configure you Job to use this listener. For example.

@Bean
public Job myJob(){
    return jobs.get("myJob")           
        .listener(new DoSomethingAroundJob())          
        .build();
}

There would be other parts of your job, but the above just shows an example of adding a listener wit JavaConfig.
