= How do I write a custom Processor which sends multiple messages?

You could use a xref:split-eip.adoc[Splitter] or use multiple
xref:message-translator.adoc[Message Translator] instances in your
route.

Or you could write a custom processor which is injected with a
`ProducerTemplate` instance that just generates N messages...

[source,java]
----
public class MyProducer implements Processor {
  ProducerTemplate producer;

  public void setProducer(ProducerTemplate producer) {
    this.producer = producer;
  }

  public void process(Exchange inExchange) {
    // some loop for each message 
    for (String template in templates) {
       // lets send a new exchange to the producers default destination
       // being called back so we can customize the message
       producer.send(new Processor() {
          public void process(Exchange outExchange) {
              outExchange.getIn().setBody("This is the body"); 
              // set some headers too?
          }
       });
    }
}
----

Then the `ProducerTemplate` can be injected -- configured in `spring.xml`
with its default URI:

[source,xml]
----
<camelContext xmlns="http://camel.apache.org/schema/spring">
  <template id="myTemplate" defaultEndpoint="activemq:someQueue"/>
</camelContext>

<bean id="foo" class="MyProducer">
  <property name="producer" ref="myTemplate"/>
</bean>
----

Note that the default output URI is inherited from the `<template/>`
configuration. If you prefer you could specify that in the
`producer.send()` method call.
