Spring Integration Extension for SMB 0.5.0 is Available

Releases | Artem Bilan | January 18, 2017 | ...

On behalf of the Spring Integration team I’d like to announce release of one more Spring Integration Extension. This time it is Spring Integration for Server Message Block and its artifact is spring-integration-smb.0.5.0.RELEASE, which is available in the Release Repository and Maven Central.

The project has been around for some time but only recently gained enough community traction to warrant a release. So, first of all, big thanks to you, the community, for your contributions!

The Java CIFS Client Library has been chosen as a Java implementation for the CIFS/SMB networking protocol. Its SmbFile abstraction is simply wrapped to the Spring Integration "Remote File" foundations like SmbSession, SmbRemoteFileTemplate etc.

The SMB Channel Adapters and support classes implementations are fully similar to existing components for (S)FTP or AWS S3 protocols. So, if you familiar with those components, it is pretty straightforward to use this extension. But any way here are several words about existing components:

SMB Inbound Channel Adapter

To download SMB files locally the SmbInboundFileSynchronizingMessageSource is provided. It is simple extension of the AbstractInboundFileSynchronizingMessageSource which requires SmbInboundFileSynchronizer injection. For filtering remote files you still can use any existing FileListFilter implementations, but particular SmbRegexPatternFileListFilter and SmbSimplePatternFileListFilter are provided. For XML configuration the <int-smb:inbound-channel-adapter> component is provided.

SMB Outbound Channel Adapter

There is no (yet) some SMB specific requirements for files transferring to SMB, so for XML <int-smb:outbound-channel-adapter> component we simply reuse an existing FileTransferringMessageHandler. In case of Java configuration that FileTransferringMessageHandler should be supplied with the SmbSessionFactory (or SmbRemoteFileTemplate) and that all!

@ServiceActivator(inputChannel = "storeToSmb")
public MessageHandler smbMessageHandler(SmbSessionFactory smbSessionFactory) {
    FileTransferringMessageHandler<SmbFile> handler =
                new FileTransferringMessageHandler<>(smbSessionFactory);
                new LiteralExpression("remote-target-dir"));
    handler.setFileNameGenerator(m ->
                m.getHeaders().get(FileHeaders.FILENAME, String.class) + ".test");
    return handler;

We would like to hear any feedback from the Community before we go straight forward to the 1.0.0.RELEASE, so, do not hesitate to contact with us via any available communication channel!
