Core classes/interfaces from Spring Integration have been moved to Spring Framework 4.0.

Users with direct references to the following classes, in order to migrate to Spring Integration 4.0 will need to change import statements to reflect these changes.

Users who do not reference framework classes from their own (POJO) code, and use the integration namespace to configure their components will need no changes.

The following classes have been moved

from org.springframework.integration to org.springframework.messaging:

  • Message
  • MessageChannel
  • MessageHandler
  • MessageHeaders
  • PollableChannel
  • SubscribableChannel
  • MessagingException
  • MessageDeliveryException
  • MessageHandlingException

from org.springframework.integration.channel to org.springframework.messaging.support:

  • AbstractMessageChannel
  • AbsractSubscribableChannel
  • ChannelInterceptor

from org.springframework.integration.core to org.springframework.messaging:

  • MessageHandler
  • MessagePostProcessor

from org.springframework.integration.channel.interceptor to org.springframework.messaging.support:

  • ChannelInterceptorAdapter

from org.springframework.integration.message to org.springframework.messaging.support:

  • ErrorMessage
