Delay Interceptor

Delayer (Interceptor)

The Delayer (Interceptor) is an route interceptor that is used for slowing processing of messages down. This allows you to enable this interceptor and set a fixed amount of delay between each step a message passes in the route path, to show how things is happening nice and slowly, so you are not bombarded with a zillion lines of logging output.

The delay interceptor can be configured as follows:

• using Java system property camel.delay=value where value is the fixed delay in millis.
• setting the delay attribute in the spring camelContext tag.
• adding the delay interceptor to the CamelContext in Java code.

Configuring as system property

You can set the delay as a JVM system property as:

-Dcamel.delay=500

Where we set the delay to 500 millis.

Configuring using Spring

Just set the delay attribute of the camelContext tag as shown below:

    <camelContext id="camel" delay="500" xmlns="http://activemq.apache.org/camel/schema/spring">
        <route>
            <from uri="direct:start"/>
            <to uri="mock:result"/>
        </route>
    </camelContext>

Configuring using Java

You can add the delayer interceptor in the RouteBulder as shown below:

    public void configure() throws Exception {
        // add the delay interceptor to delay each step 200 millis
        getContext().addInterceptStrategy(new Delayer(200));

       ... // regular routes here
    }
