如果您没有看到根本错误：

因此出现了ftp故障，但问题是无法解决此错误。由于此错误，此异常将永久抛出-即在每次轮询时都无法加载文件，因此永远不会将其放入元数据存储中。
我想知道的是如何“吞噬”此错误并移至下一个文件？
我确实怀疑这是因为文件名的大小。 Ftp未下载它，因为它太大。在那里，就像在扫描目录时发现的那样，但是到下载目录时，失败了。
答案 0 :(得分：0)
您可以手动将错误的文件添加到MetadataStore。
或者您可以对过滤器进行子类化，覆盖rollback()以跳过回滚列表中的第一个文件。
但是，不幸的是，rollback()没有执行回滚的原因的信息，因此即使出现其他错误，该操作也会始终跳过第一个文件。
