How to add payload (xml response & request logging) to CXF web service?

Question

Colleagues, hello. I'm a little confused. I have a simple dataflow made on Mule like this http://snag.gy/cJkzg.jpg In fact it is a CXF SOAP web service.

Now i need to add response and request xml logging, but i don't know which way to select. As i understood from internet there is next approaches: 1. Add Mule Logger element 2. Under src/main/resources/META-INF/cxf/ (I have not this folder) create a file named org.apache.cxf.Logger with the following contents -

org.apache.cxf.common.logging.Log4jLogger

and then add logger into my \src\main\resources\log4j.properties file.

It seems that's all I knew

At the current moment my log4j.properties looks like:

log.dir=./logs datestamp=dd.MM.yyyy HH:mm:ss.SSS log4j.rootLogger=INFO, stdout, defaultLog, errorlog

all INFO logs log4j.appender.defaultLog=org.apache.log4j.RollingFileAppender

log4j.appender.defaultLog.Threshold=TRACE log4j.appender.file.MaxFileSize=5MB log4j.appender.file.MaxBackupIndex=10 log4j.appender.defaultLog.File=${log.dir}/serv.log log4j.appender.defaultLog.layout=org.apache.log4j.PatternLayout log4j.appender.defaultLog.layout.ConversionPattern=%d{${datestamp}} %-5p %c{1}:%L - %m%n log4j.appender.defaultLog.encoding=UTF-8

ERROR log log4j.appender.errorlog=org.apache.log4j.RollingFileAppender

log4j.appender.errorlog.Threshold=ERROR log4j.appender.file.MaxFileSize=5MB log4j.appender.file.MaxBackupIndex=10 log4j.appender.errorlog.File=${log.dir}/serv.err log4j.appender.errorlog.layout=org.apache.log4j.PatternLayout log4j.appender.errorlog.layout.ConversionPattern=%d{${datestamp}} %-5p %c{1}:%L - %m%n

log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.Threshold=TRACE log4j.appender.stdout.Target=System.out log4j.appender.stdout.layout=org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern=%d{${datestamp}} %-5p %c{1}:%L - %m%n log4j.appender.stdout.encoding=UTF-8

As you see this properties file does not support payload logging.

How to add request & response logging in my case? I will be grateful for any code samples.
Thank you.

UPDATE

I added interceptors into flow:

<?xml version="1.0"?>
<flow name="Flow1" name="Flow1">
        <inbound-endpoint exchange-pattern="request-response" host="localhost" port="45555" path="wserv" name="HTTP"/>
        <jaxws-service serviceClass="com.maya.ws.EndPoindImpl" name="CXF">

         <inInterceptors>
                    <bean class="org.apache.cxf.interceptor.LoggingInInterceptor"/>
                </inInterceptors>
                <outInterceptors>
                    <bean class="org.apache.cxf.interceptor.LoggingOutInterceptor"/>
    </outInterceptors>

       </jaxws-service> 

        <component class="com.maya.ws.EndPoindImpl" name="Java"/>
    </flow>

And now i have xml payloads in console, but noy in log file.

UPDATE 2 Next lines added into log4j.properties

log4j.logger.org.apache.cxf.interceptor.LoggingOutInterceptor=TRACE, queryLog log4j.additivity.org.apache.cxf.interceptor.LoggingOutInterceptor=true

log4j.logger.org.apache.cxf.interceptor.LoggingInInterceptor=TRACE, queryLog log4j.additivity.org.apache.cxf.interceptor.LoggingInInterceptor=true

Query log log4j.appender.queryLog=org.apache.log4j.DailyRollingFileAppender

log4j.appender.queryLog.File=${log.dir}/queryLog.log log4j.appender.queryLog.layout=org.apache.log4j.PatternLayout log4j.appender.queryLog.layout.ConversionPattern=%d [%t] %-5p %c %x - %m%n log4j.appender.queryLog.DatePattern = '.'yyyy-MM-dd log4j.category.queryLogger=INFO, queryLog

queryLog is created but it is empty. =(

UPDATE 3

I add queryLog to the end of

log4j.rootLogger=INFO, stdout, defaultLog, errorlog

Now i have payloads in queryLog.log but the response looks as string. I'am trying to convert it in pretty xml.

Any idea how to convert into pretty xml response string in queryLog? :

Payload: <soap:Envelope
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body> bla
bla bla bla

You can simply put a Logger in your flow in the Studio and set its message to #[payload], or add a tag in the XML config mode. If the payload is a string, that will work directly, if it's a more complex object it will just print the object reference.

Generally you can add an Object to string transformer before you need to log your data. Sometimes you will have to be more creative with your transformations - check out what are available in Studio and don't be afraid to experiment.
