Method Detail

handleRequestMessage

protected final Object handleRequestMessage(Message<?> message)

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

handleResult

protected void handleResult(Object result,
                            MessageHeaders requestHeaders,
                            MessageChannel replyChannel)

Overrides:

handleResult in class AbstractReplyProducingMessageHandler

getComponentType

public String getComponentType()

Description copied from class: IntegrationObjectSupport

Subclasses may implement this method to provide component type information.

Specified by:

getComponentType in interface NamedComponent

Overrides:

getComponentType in class AbstractMessageHandler

splitMessage

protected abstract Object splitMessage(Message<?> message)

Subclasses must override this method to split the received Message. The return value may be a Collection or Array. The individual elements may be Messages, but it is not necessary. If the elements are not Messages, each will be provided as the payload of a Message. It is also acceptable to return a single Object or Message. In that case, a single reply Message will be produced.
