我知道这已被问过很多次，但我不能 找到问题的答案。我试图每隔20秒安排一次春季批次，但它会失败。

请有人调查并让我知道这个问题。
答案 0 :(得分：3)
你在try / catch中吞下了异常，而只记录了异常发生的事实，但没有记录它是什么样的异常。如果您将日志记录语句更改为：
log.error("Encountered job execution exception!", e);
您会看到错误说明：
org.springframework.batch.core.launch.NoSuchJobException: No job configuration with the name [Test_Job] was registered
您已宣布名为job1的作业，而不是Test_Job，这就是您获取例外的原因。您必须将作业数据映射更改为：
map.put("jobName", "job1");
这将删除异常，但由于Spring Batch需要使用唯一的作业参数来重新启动它，您的作业仍将运行一次，有关说明，请参阅this answer。 因此，您必须将您的作业执行修改为类似的（最简单的），以便能够连续运行它：
@Override
protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
try {
Job job = jobLocator.getJob(jobName);
Map<String, JobParameter> parametersMap = new HashMap<>();
parametersMap.put("timestamp", new JobParameter(System.currentTimeMillis()));
JobParameters jobParameters = new JobParameters(parametersMap);
JobExecution jobExecution = jobLauncher.run(job, jobParameters);
log.info("{}_{} was completed successfully", job.getName(), jobExecution.getId());
} catch (Exception e) {
log.error("Encountered job execution exception!", e);
}
}
