Description copied from class: AbstractMessageSource

Subclasses must implement this method. Typically, the returned value will be the payload of type T, but the returned value may also be a Message instance whose payload is of type T; also can be AbstractIntegrationMessageBuilder which is used for additional headers population.

Specified by:

doReceive in class AbstractMessageSource<Object>

Returns:

The value returned.
