Return Address
Camel supports the Return Address from the EIP patterns.
How does a replier know where to send the reply?
The request message should contain a Return Address that indicates where to send the reply message.
Camel supports Return Address by messaging Components that provides this functionality such as the JMS component via the JMSReplyTo
header.
Example
In the example below we send a message to the JMS cheese queue using InOut
mode, this means that Camel will automatically configure the JMSReplyTo
header with a temporary queue as the Return Address.
from("direct:foo")
.to(ExchangePattern.InOut, "jms:queue:cheese");
And in XML
<route>
<from uri="direct:foo"/>
<to pattern="InOut" uri="jms:queue:cheese"/>
</route>
You can also specify a named reply queue with the replyTo
option (instead of a temporary queue). When doing so then InOut
mode is implied:
from("direct:foo")
.to("jms:queue:cheese?replyTo=myReplyQueue");
And in XML
<route>
<from uri="direct:foo"/>
<to uri="jms:queue:cheese?replyTo=myReplyQueue"/>
</route>
