The URI is just a string.
Why not extract your "builder" into a simple utility method
public class EndpointUtils {
public static String rabbitEndpoint(String scheme, String host, String
host) {
...
}
}
With SpringDSL property placeholder come into mind ...
Having special builders sound also fine, but a lot of work as it requires one
builder per endpoint ...
