extends Object
implements ChannelInterceptor
Class Inheritance
All Implemented Interfaces
org.springframework.messaging.support.ChannelInterceptor
Imports
org.springframework.messaging.Message, .MessageChannel
A simpler interceptor that calls MessageHeaderAccessor#setImmutable() on the headers of messages passed through the preSend method.

When configured as the last interceptor in a chain, it allows the component sending the message to leave headers mutable for interceptors to modify prior to the message actually being sent and exposed to concurrent access.
