Spring Batch在schdeule上多次重新运行步骤

Question

@Scheduled(fixedRate=30*1000)
@SchedulerLock(name = "job-1", lockAtLeastFor = "15S", lockAtMostFor = "20S")
public void batchJob() throws InterruptedException {
JobParameters Parameters = new JobParametersBuilder()
    .addLong("startAt", System.currentTimeMillis()).toJobParameters();
try {
    jobLauncher.run(job, Parameters);
} catch (JobExecutionAlreadyRunningException | JobRestartException
    | JobInstanceAlreadyCompleteException | JobParametersInvalidException e) {

    e.printStackTrace();
}

     // Executes the job
  @Bean
  public Job jobUpdate(JobCompletionNotificationListener listener, Step step1) {
    return this.jobBuilderFactory.get("employee")
        .listener(listener)
        .incrementer(new RunIdIncrementer())
        .start(step1)
        .build();
  }


  @Bean
  public Step step1() {
    return stepBuilderFactory.get("step1")
        .allowStartIfComplete(true)
        .<Employee, Employee>chunk(2)
        .reader(reader())
        .processor(processor())
        .faultTolerant().skipPolicy(httpClientExceptionSkipper())
        .writer(compositeItemWriter())
        .build();
  }

如果有人能对此有所了解，我真的很感激。

我在step1()方法上没有看到@jobscope，对吗？

此外，您应该将重新运行作业而不是步骤称为：）

通常，一个作业参数应该足以定义一个新的作业，因此不需要其他东西重新运行作业，在您的情况下是从作业参数中重新运行一个作业。
