Camel supports the Message from the EIP patterns using the Message interface.

To support various message exchange patterns like one way Event Message and Request Reply messages Camel uses an Exchange interface which has a pattern property which can be set to InOnly for an Event Message which has a single inbound Message, or InOut for a Request Reply where there is an inbound and outbound message.

Here is a basic example of sending a Message to a route in InOnly and InOut modes

Requestor Code

//InOnly
getContext().createProducerTemplate().sendBody("direct:startInOnly", 
   "Hello World");

//InOut
String result = (String) getContext().createProducerTemplate().requestBody(
   "direct:startInOut", "Hello World");

Route Using the Fluent Builders

from("direct:startInOnly").inOnly("bean:process");
	
from("direct:startInOut").inOut("bean:process");

Route Using the Spring XML Extensions

<route>
   <from uri="direct:startInOnly"/>
   <inOnly uri="bean:process"/>
</route>

<route>
   <from uri="direct:startInOut"/>
   <inOut uri="bean:process"/>
</route>
