Description copied from class: AbstractReplyProducingMessageHandler

Subclasses must implement this method to handle the request Message. The return value may be a Message, a MessageBuilder, or any plain Object. The base class will handle the final creation of a reply Message from any of those starting points. If the return value is null, the Message flow will end here.

Specified by:

handleRequestMessage in class AbstractReplyProducingMessageHandler

Parameters:

requestMessage - The request message.

Returns:

The result of handling the message, or null.
