我有一个从the documentation创建的Spring批处理作业。
应用程序永不退出。作业位于状态为STATUS = STOPPING，EXIT_CODE = COMPLETED的存储库中。
我希望作业的状态为已停止。通过添加System.exit（）退出应用程序是否合适？
我在afterJob（）侦听器中添加了日志记录，它记录了唯一步骤的状态为COMPLETED，并且步骤出口状态也为COMPLETED。有趣的是，jobExecution的作业状态也为COMPLETED，但是随后从SimpleJobLauncher进行的默认日志记录将记录状态为STOPPING。
Spring Batch starter 2.1.2发布
编辑：
[BatchJobCompletionNotificationListener] !!!工作已完成！
[BatchJobCompletionNotificationListener]作业不再以状态[STOPPING]退出状态[exitCode = COMPLETED; exitDescription =]运行。
[BatchJobCompletionNotificationListener]步骤[step1]状态[COMPLETED]退出状态[exitCode = COMPLETED; exitDescription =]。
[SimpleJobLauncher]作业：[FlowJob：[name = myjob]]使用以下参数完成：[{run.id = 62，-spring.config.location = application.yaml}]和以下状态：[正在停止] ]
这就是我的日志记录的结尾。
不确定是否应该有所作为，但是我正在将JdbcPagingItemReader与PagingQueryProvider一起使用（基于this example

只需尝试使用引导2.1.2RLEASE入门指南，它就会按预期工作：

通过添加System.exit（）退出应用程序是否合适？
否，您应该正常关闭应用程序以正确释放任何资源并避免资源泄漏。
