Intercept and log incoming message to endpoint

Question

I want to log the incoming SOAP in my beans setup but I don't know how to intercept the requested body.

I found out if I add ?dataFormat=MESSAGE to my CxfEndpoint it shows the xml input but messes up the dataFormat that provides the addBookTransformer.

<from uri="cxf:bean:CxfEndpoint?dataFormat=MESSAGE" /> 

This is my setup

<cxf:cxfEndpoint id="CxfEndpoint"
    address="/host/addBook"
    endpointName="a:addBookEndpoint"
    serviceName="a:addBookService"
    wsdlURL="wsdl/add-book.wsdl"
    serviceClass="com.library.AddBookEndpoint"
    xmlns:a="http://library.com"/>

<bean id="addBookTransformer" class="com.library.bookshelf.AddBookTransformer"/>

<camelContext xmlns="http://camel.apache.org/schema/spring">
    <route id="addBook" streamCache="true">
        <from uri="cxf:bean:CxfEndpoint" />
        <process ref="addBookTransformer" />
        <log message="${body}"/>
    </route>
</camelContext>

Is there a way to itercept and log the incoming post request data?

You could do wiretap for this

<camelContext xmlns="http://camel.apache.org/schema/spring">
    <route id="addBook" streamCache="true">
        <from uri="cxf:bean:CxfEndpoint" />
        <process ref="addBookTransformer" />
        <wireTap uri="direct:tap"/>
        <to uri="mock:result"/>
        <log message="${body}"/>
    </route>
</camelContext>

A copy of the exchange is sent to direct:tap which you can read and process however you want.

For example we could just log the message like this. You could also add another processor.

<route id="wiretapped" streamCache="true">
     <from uri="direct:tap" />
     <log message="${body}"/>
</route>

Here is the documentation for this.
