Apache Camel - How to set a private key in a dinamic sftp endpoint

问题

Using Java DSL, I have a route in which I poll a file in an SFTP server using the file name set in the message headers

from("direct:download")
        .pollEnrich()
        .simple("sftp://my.host:22/folder/?username=foo&fileName=${header.CamelFileName}")
        .to("file://state/downloaded");

The sftp endpoint needs to have set a private key. Usually something like this suffices:

        endpoint("sftp://my.host:22/folder/?username=foo&fileName=my_file_explicitly_written_here", SftpEndpoint.class).getConfiguration().setPrivateKey(getSshPrivateKey());

However, I see no way to "mix" dynamic fields in the URI (${header.CamelFileName}) in the pollEnrich().simple()) with endpoint configuration.

Any suggestion on this?

回答1:

You can reference privateKey as bean from registry.

.pollEnrich()
    .simple("sftp://my.host:22/folder/?username=foo&privateKey=#myKeyInRegistry&fileName=${header.CamelFileName}")

Binding bean to registry depends on platform and Camel version you are using.
