Configure Log4j with CXF

Configure Log4j with CXF explains step by step details of configuring Log4j and Apache CXF Webservice.

For every application logging has a vital role because it is a must for various debugging purpose, CXF framework have in-built feature for enabling logging of request and response payloads

log4j is commonly used logging framework in java, this tutorial is using log4j as the logging tool.

You can also see server side/client side logging Apache CXF Logging

Here I am showing How to use Log4j for logging CXF soap messages

I am going to reuse my CXF Web Service Tutorial

You need to download following additional library

  1. log4j2

Following jars must be in classpath

  1. cxf-core-3.3.6.jar
  2. cxf-rt-bindings-soap-3.3.6.jar
  3. cxf-rt-databinding-jaxb-3.3.6.jar

  26. woodstox-core-5.0.3.jar
  27. wsdl4j-1.6.3.jar
  28. xmlschema-core-2.2.5.jar

Please see the project structure on below screenshot

Log4j with CXF

Now you need to create two additional files, 1) org.apache.cxf.Logger 2) log4j.properties, you can see the file name and its contents below, please drop both of these files according to the above screen shot.

org.apache.cxf.Logger

org.apache.cxf.common.logging.Slf4jLogger

log4j2.xml

<?xml version="1.0" encoding="UTF-8"?>
<Configuration monitorInterval="60">

	<!-- PROPERTIES -->
	<Properties>
		<Property name="layout">%d{HH:mm:ss.SSS}

	</Properties>

	<!-- APPENDERS -->
	<Appenders>

			<DefaultRolloverStrategy max="30" />
			<PatternLayout pattern="${layout}" />
		</RollingFile>
	</Appenders>

	<!-- LOGGERS -->
	<Loggers>
		<Logger name="org.apache.cxf.services" level="INFO" additivity="false">
			<!-- specify a dedicated appender for the SOAP messages -->
			<AppenderRef ref="CXF_LOG_FILE" />
		</Logger>
	</Loggers>

</Configuration>

cxf.xml

Modify cxf.xml (add inInterceptors & outInterceptors) in order to show SOAP inbound/outbound messages

<beans xmlns="http://www.springframework.org/schema/beans" xmlns:cxf="http://cxf.apache.org/core"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jaxws="http://cxf.apache.org/jaxws"
	xsi:schemaLocation="http://cxf.apache.org/core http://cxf.apache.org/schemas/core.xsd

<cxf:bus>
    <cxf:features>
        <bean class="org.apache.cxf.ext.logging.LoggingFeature">
            <property name="prettyLogging" value="true"/>
        </bean>
    </cxf:features>
</cxf:bus>

<jaxws:endpoint id="changeStudent" implementor="com.student.ChangeStudentDetailsImpl"
		address="/ChangeStudent" />
</beans>

you can also see CXF client example in order to run this service

After running the client, you can see the logs on console as well as configured directory, in our case it is cxf-soap-logs.txt

cxf-soap-logs.txt
