Spring批处理应用程序失败，没有任何错误消息。

Question

要求：

从包含100 K记录的文件中读取。

对于每个记录，从表中检索数据，然后从NuoDB数据库表中检索数据。

最后，将更新的记录插入到NuoDB数据库表中。

设计方法:面向块的处理，从文件中读取1000条记录，并将其处理并写入数据库。

问题:在记录了大约14K并运行了将近一个小时后，批处理应用程序失败了，出现了以下错误：

我找不到这份工作失败的真正原因。日志级别处于调试模式，但仍未报告结论性错误。

直到下一行，日志显示得如出一辙，但在下面一行之后，我们可以观察到主线程已经消失，Thread-9也出现了。主线程关闭的原因。Spring批处理是否有线程的默认时间限制？

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

另一个注意事项:应用程序的设计如下：

MyApplication_1.0.jar.

• Please

• 有一个JAR文件(应用程序jar文件)，即MyApplication1.0.jar.

• The调度程序将为具有不同参数的两个作业调用相同的MyApplication1.0.jar文件，如java -jar MyApplication1.0.jar --job=job1和java -jar MyApplication1.0.jar --job=job2

• The 2作业相应地调度，Job1 is scheduled at 21:00 hours和Job2 is scheduled at 22:00 hours.

• Please认为Job1处理大文件，完成任务需要超过1个小时。

• 所以可能存在这样一种情况，即Job1在21:00和22:00仍在运行，当调度程序在22:00触发Job2时，Job1线程立即失败。

Answer 1

这一行看起来很可疑--难道您的批处理没有找到任何要做的事情，并为此进行了彻底的退出吗？
