Overrides:

createExpressionEvaluatingHandler in class AbstractStandardMessageHandlerFactoryBean

createHandler

protected MessageTransformingHandler createHandler(Transformer transformer)

canBeUsedDirect

protected boolean canBeUsedDirect(AbstractMessageProducingHandler handler)

Always returns true - any AbstractMessageProducingHandler can be used directly.

Overrides:

canBeUsedDirect in class AbstractStandardMessageHandlerFactoryBean

getPreCreationHandlerType

protected java.lang.Class<? extends org.springframework.messaging.MessageHandler> getPreCreationHandlerType()

Description copied from class: AbstractSimpleMessageHandlerFactoryBean
