Interface MessagePostProcessor

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface MessagePostProcessor

Post-processes a Message. This is the JMS equivalent of the spring-messaging MessagePostProcessor.

This is involved right before a JmsClient sends a message over the wire, for setting additional JMS properties and headers. With JmsTemplate, the message post processor is only involved in methods accepting it as an argument, to customize the outgoing message produced by a MessageConverter.
