Spring Integration SMB is invalid on linux(CentOS 7)

Question

I used Spring Integration SMB to upload local files to Windows shared folder, and I can run normally in the local windows environment and idea, but when I put the application into a jar package and put it on the CentOS 7 server, I found that it failed, without any Integration related output logs, it just didn't work. What causes this?

I have installed the smb service on the server, and port 445 is enabled. smbclient and mount -t cifs can be used to access and mount the smb service. I have configured the minimum and maximum SMB version numbers to ensure that smb2 or SMB2-3 does not work

help~!!!!

This problem has been solved!!!

The problem is not in the linux or windows system environment, but when packaging jars on windows, there is a problem. The shade plug-in I use for fat jar packaging affects the bouncy castle signature that jcifs relies on. As a result, `the JCE cannot authenticate the provider BC error occurred. I repackaged the independent jar package and copied the lib package to a lib directory separately. After starting the jar, I successfully ran and uploaded the file.

However, I still don't know why there is no error in Integration. I got the error information by directly using Jcifs under Integration dependency. Maybe I didn't configure the errorChannel of Integration properly, right
