Durable Subscriber
Camel supports the Durable Subscriber from the EIP patterns using the JMS component which supports publish & subscribe using Topics with support for non-durable and durable subscribers.
Another alternative is to combine the Message Dispatcher or Content Based Router with File or JPA components for durable subscribers then something like Seda for non-durable.
Here is a simple example of creating durable subscribers to a JMS topic
Using the Fluent Builders
| Code Block | ||||
|---|---|---|---|---|
| ||||
from("direct:start").to("activemq:topic:foo");
from("activemq:topic:foo?clientId=1&durableSubscriptionName=bar1").to("mock:result1");
from("activemq:topic:foo?clientId=2&durableSubscriptionName=bar2").to("mock:result2");
|
Using the Spring XML Extensions
| Code Block | ||||
|---|---|---|---|---|
| ||||
<route>
<from uri="direct:start"/>
<to uri="activemq:topic:foo"/>
</route>
<route>
<from uri="activemq:topic:foo?clientId=1&durableSubscriptionName=bar1"/>
<to uri="mock:result1"/>
</route>
<route>
<from uri="activemq:topic:foo?clientId=2&durableSubscriptionName=bar2"/>
<to uri="mock:result2"/>
</route>

Here is another example of JMS durable subscribers, but this time using virtual topics (recommended by AMQ over durable subscriptions)
Using the Fluent Builders
| Code Block | ||||
|---|---|---|---|---|
| ||||
from("direct:start").to("activemq:topic:VirtualTopic.foo");
from("activemq:queue:Consumer.1.VirtualTopic.foo").to("mock:result1");
from("activemq:queue:Consumer.2.VirtualTopic.foo").to("mock:result2");
|
Using the Spring XML Extensions
| Code Block | ||||
|---|---|---|---|---|
| ||||
<route>
<from uri="direct:start"/>
<to uri="activemq:topic:VirtualTopic.foo"/>
</route>
<route>
<from uri="activemq:queue:Consumer.1.VirtualTopic.foo"/>
<to uri="mock:result1"/>
</route>
<route>
<from uri="activemq:queue:Consumer.2.VirtualTopic.foo"/>
<to uri="mock:result2"/>
</route>
