CXF 3.1 wsdl2java logging with Log4j2

Question

I have generated my service using CXF 3.1 wsdl2java, so no cxf.xml.

I am trying to add the request and response XML for the service to my log4j2 setup. There is a lot of conflicting information due to version changes etc. My request/response xml CXF logging file is always empty.

This was the closest to my setup: How to log CXF webservice requests with log4j2?

So I have the following in my log4j2.xml

    <logger name="org.apache.cxf" additivity="false" level="info">
            <AppenderRef ref="APP_LOG_FILE"/>
    </logger>
    <logger name="org.apache.cxf.interceptor.LoggingInInterceptor" additivity="false" level="info">
        <AppenderRef ref="WS_LOG_FILE" />
    </logger>
    <logger name="org.apache.cxf.interceptor.LoggingOutInterceptor" additivity="false" level="info">
        <AppenderRef ref="WS_LOG_FILE" />
    </logger>

Not showing the appenders, but they are there, the APP_LOG_FILE is populated but the WS_LOG_FILE appender files is always empty, while messages being exchanged.

I added a META-INF/cxf/org.apache.cxf.Logger file with this content

org.apache.cxf.common.logging.Slf4jLogger

I also tried using the additional command line parameter when running my jar as an alternative to the cxf.Logger file:

-Dorg.apache.cxf.Logger=org.apache.cxf.common.logging.Slf4jLogger

I added the additional dependency:

<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-slf4j-impl</artifactId>
    <version>2.0</version>
</dependency>

I tried the following both with the logging interceptors (are they required or an alternative to the config in the log4j2.xml?) and without them, as shown currently commented out.

    GetComparisonDecisionService equinitiComparisonService = new GetComparisonDecisionService();
    GetComparisonDecisionInterface comparison = equinitiComparisonService.getGetComparisonDecision();
/*
    Client client = ClientProxy.getClient(equinitiComparisonService.getPort(GetComparisonDecisionInterface.class));
    client.getInInterceptors().add(new LoggingInInterceptor());
    client.getOutInterceptors().add(new LoggingOutInterceptor());
*/
    GetComparisonDecisionCallParameter comparisonDecisionCallParameter = new GetComparisonDecisionCallParameter();
    comparisonDecisionCallParameter.setSecurityToken(token);
    comparisonDecisionCallParameter.setComparisonApplication(equinitiApp);

    GetComparisonDecisionResponseParameter eqDescn = comparison.getComparisonDecision(comparisonDecisionCallParameter);

I have run out of ideas at this point. The cxf documentation is very terse.

As requested as an answer: Setting the LoggingInterceptors the way you show in the last code-fragment is recommended for CXF < 3.1. You should use the @Feature-Annotation like this: @Features(features = "org.apache.cxf.feature.LoggingFeature").
