Since we're on a major migration process of this website, some component documents here are out of sync right now. In the meantime you may want to look at the early version of the new website
https://camel.apache.org/staging/
We would very much like to receive any feedback on the new site, please join the discussion on the Camel user mailing list.
Ref ComponentThe ref: component is used for lookup of existing endpoints bound in the Registry. URI formatref: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, Runtime lookupThis component can be 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: // 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: <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> SampleIn the sample below we use the <bean id="mybean" class="org.apache.camel.spring.example.DummyBean"> <property name="endpoint" ref="endpoint1"/> </bean> <camelContext id="camel" xmlns="http://camel.apache.org/schema/spring"> <jmxAgent id="agent" disabled="true"/> <endpoint id="endpoint1" uri="direct:start"/> <endpoint id="endpoint2" uri="mock:end"/> <route> <from uri="ref:endpoint1"/> <to uri="ref:endpoint2"/> </route> </camelContext> You could, of course, have used the <to ref="endpoint2"/> Which is the more common way to write it. |
