我目前正在 Spring Integration 中设计一个集成流程，其中我使用 FileSplitter 处理程序拆分文件并将结果发送到另一个服务。我目前正在使用 FileSystemPersistentAcceptOnceFileListFilter 处理“重复”文件，但我还想添加在使用 FileSplitter 读取文件后重命名文件的功能，最简单的实现方法是什么这个？
最佳答案
FileSplitter 有markers 选项。这样它就会产生 START 和 END 消息。因此，当您收到 END 时，您可以执行所需的重命名逻辑:
Set to true to emit start/end of file marker messages before and after the file data. Markers are messages with FileSplitter.FileMarker payloads (with START and END values in the mark property). Markers might be used when sequentially processing files in a downstream flow where some lines are filtered. They enable the downstream processing to know when a file has been completely processed. In addition, a header file_marker containing START or END are added to these messages. The END marker includes a line count. If the file is empty, only START and END markers are emitted with 0 as the lineCount. Default: false. When true, apply-sequence is false by default. Also see markers-json.
有一个sample application具有类似的功能。
