please tell me how you can get files recursively from subdirectories?
I add an expression to select a remote directory to my IntegrationFlow - String fileNameRegex = "(\ d {4} | Success | Error |. *. Xml)"; Ftp.inboundStreamingAdapter (template ()). RemoteDirectory (new ValueExpression <> (fileNameRegex))
But this does not work, files are taken only from the root directory.
The directory structure is as follows:
/
1111/
In/
Out/
Error/
Success/
2222/
In/
Out/
Error/
Success/
I only need to get files from Error and Success *.xml
