The wire tap pattern enables you to monitor the messages passing
through a channel by duplicating the message stream: one copy of the stream is forwarded to
the main channel and another copy of the stream is forwarded to the
tap endpoint, which monitors the stream.
The following example shows how to route a request from an input queue:a endpoint to the wire tap location queue:tap before it
is received by queue:b.
RouteBuilder builder = new RouteBuilder() {
public void configure() {
from("seda:a").to("seda:tap", "seda:b");
}
};XML configuration example
The following example shows how to configure the same route in XML:
<camelContext id="buildWireTap" xmlns="http://activemq.apache.org/camel/schema/spring">
<route>
<from uri="seda:a"/>
<to uri="seda:tap"/>
<to uri="seda:b"/>
</route>
</camelContext>
