Set Body

The Message Translator can be done in different ways in Camel:

Using Transform or Set Body in the DSL
Calling a Processor or bean to perform the transformation
Using template-based Components, with the template being the source for how the message is translated
Messages can also be transformed using Data Format to marshal and unmarshal messages in different encodings.

This page is documenting the first approach by using Set Body EIP.

Options

The Set Body eip has no options.

You can use a Set Body which uses an Expression to do the transformation:

In the example below we prepend Hello to the message body using the Simple language:

from("direct:cheese")
    .setBody(simple("Hello ${body}"))
    .to("log:hello");

And in XML DSL:

<route>
    <from uri="direct:cheese"/>
    <setBody>
        <simple>Hello ${body}</simple>
    </setBody>
    <to uri="log:hello"/>
</route>

The Transform EIP always sets the result on the OUT message body.

Set Body sets the result accordingly to the Exchange Pattern on the Exchange.
