URI format
| Code Block |
|---|
ref:someName[?options]
|
Where someName is the name of an endpoint in the Registry (usually, but not always, the Spring registry). If you are using the Spring registry, someName would be the bean ID of an endpoint in the Spring registry.
Runtime lookup
This component can be any string which is used to lookup the endpoint in the Registry.used when you need dynamic discovery of endpoints in the Registry where you can compute the URI at runtime. Then you can look up the endpoint using the following code:
| Code Block |
|---|
|
// lookup the endpoint
String myEndpointRef = "bigspenderOrder";
Endpoint endpoint = context.getEndpoint("ref:" + myEndpointRef);
Producer producer = endpoint.createProducer();
Exchange exchange = producer.createExchange();
exchange.getIn().setBody(payloadToSend);
// send the exchange
producer.process(exchange);
...
|
And you could have a list of endpoints defined in the Registry such as:
| Code Block |
|---|
|
<camelContext id="camel" xmlns="http://activemq.apache.org/camel/schema/spring">
<endpoint id="normalOrder" uri="activemq:order.slow"/>
<endpoint id="bigspenderOrder" uri="activemq:order.high"/>
...
</camelContext>
|
Sample
In the sample below we use the ref: in the URI to reference the endpoint with the spring ID, endpoint2:
| Wiki Markup |
|---|
{snippet:id=example|lang=xml|url=camel/trunk/components/camel-spring/src/test/resources/org/apache/camel/spring/endpointReference.xml} |
You could, of course, have used the ref attribute instead:
| Code Block |
|---|
|
<to ref="endpoint2"/>
|
Which is the more common way to write it.
