java - Spring Batch 应用程序失败且没有任何错误消息

Question

要求:

从包含 100K 记录的文件中读取。

对于每条记录，从 IBM DB2 数据库表中检索数据，然后从 NuoDB 数据库表中检索数据。

最后，将更新的记录插入NuoDB数据库表中。

设计方法:面向 block 的处理，将从文件中读取 1000 条记录，进行处理并写入数据库。

问题:在大约 14K 记录并运行近 1 小时后，批处理应用程序失败并出现以下错误:

我无法找到这项工作失败的真正原因。日志级别处于DEBUG模式，但仍然没有报告结论性错误。

到下面这行，日志按预期显示，但是在下面这行之后，我们可以观察到主线程消失了，Thread-9 进来了。为什么主线程被关闭。 Spring Batch 是否有线程的默认时间限制？

select NuoDB_TABLE.* from TABLE2 NuoDB_TABLE where NuoDB_TABLE.COLUMN1=?

还有另一个观察结果:该应用程序的设计如下:

• 有 1 个 JAR 文件(应用程序 jar 文件)，即 MyApplication_1.0.jar。
• 请考虑在 MyApplication1.0.jar 中设计的 2 个作业。
• 调度程序将为具有不同参数的 2 个作业调用相同的 MyApplication1.0.jar 文件，例如 java -jar MyApplication1.0.jar --job=job1 和 java - jar MyApplication1.0.jar --job=job2
• 这 2 项工作已相应安排，作业 1 安排在 21:00 ，作业 2 安排在 22:00 。
• 请考虑到 Job1 处理大文件，需要 1 个多小时才能完成该作业。
• 那么是否存在这样一种情况，Job1 从 21:00 开始一直运行到 22:00，当调度程序在 22:00 触发 Job2 时，Job1 线程立即失败。

这条线看起来很可疑 - 是否有可能您的批处理只是找不到任何可做的事情并因此干净退出？
