Camel supports the Service Activator from the EIP patterns book.
How can an application design a service to be invoked both via various messaging technologies and via non-messaging techniques?
Design a Service Activator that connects the messages on the channel to the service being accessed.
Camel has several Components that support the Service Activator EIP.
Components like Bean and CXF provide a way to bind the message Exchange to a Java interface/service where the route defines the endpoints and wires it up to the bean.
In addition, you can use the Bean Integration to wire messages to a bean using Java annotation.
