Messaging Gateway

Camel supports the Messaging Gateway from the EIP patterns book.

How do you encapsulate access to the messaging system from the rest of the application?

Use a Messaging Gateway, a class than wraps messaging-specific method calls and exposes domain-specific methods to the application.

Camel has several endpoint components that support the Messaging Gateway from the EIP patterns. Components like Bean provides a way to bind a Java interface to the message exchange.

Another approach is to use @Produce annotations (POJO Producing) which also can be used to hide Camel APIs and thereby encapsulate access, acting as a Messaging Gateway EIP solution.
