java.nio.file.FileSystemException进程无法访问该文件，因为其他进程正在使用该文件 [英] java.nio.file.FileSystemException The process cannot access the file because it is being used by another process
本文介绍了java.nio.file.FileSystemException进程无法访问该文件，因为其他进程正在使用该文件的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我在spring-boot应用程序中使用spring batch。Spring Boot版本为2.3.3.RELEASE。
multi-step job，在第一步中validates xml file header然后readtransaction在chunk oriented step中，对每个事务做一些business logic，然后write将其返回到XML文件。在third也是最后一步中，当我尝试delete the input file时，它抛出FileSystemException。
更新：即使在作业完成后，我也无法删除输入文件。

您的问题是将CompositeItemWriter与两个委托一起使用，但您没有在步骤中将委托注册为流。本例中发生的情况是未调用ItemStream#close方法，因此资源未正确释放。
如reference documentation中所述，您需要手动将委派编写器(在您的情况下为edsClientItemWriter和omegaXmlFileWriter)注册为步骤中的项流。
这篇关于java.nio.file.FileSystemException进程无法访问该文件，因为其他进程正在使用该文件的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
