Apache CXF Logging

Apache CXF Logging explains about  configure / enable logging of request and response using CXF framework

For every application logging is vital because it is a must for debugging web services, CXF framework have in-built feature for enabling logging of request / response 

You can Enable / Configure CXF Logging using two ways

1) Server Side Logging   2) Client Side Logging

If you are interested to add logs in separate file using log4j, you can find below article

Configure Log4j with CXF

CXF Server Side Logging

Here I am going to re-use CXF Web Service Tutorial

Note

Server side logging is applicable to both JAX-RS (Restful Services) and JAX-WS

You can configure logging into CXF Restful Tutorial, Only thing need to change is cxf.xml as mentioned below

You can enable Server Side Logging using two ways

1) Using Interceptor   2) Using cxf:features

For enabling server side logging using Interceptor you need to add logInInterceptor & logOutInterceptor

You need to import xmlns:cxf namespace in order to use <cxf:bus>

please check the following changed cxf.xml

cxf.xml

<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  
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">
	<import resource="classpath:META-INF/cxf/cxf.xml" />
	<bean class="org.apache.cxf.ext.logging.LoggingInInterceptor" id="logInInterceptor" />
	<bean class="org.apache.cxf.ext.logging.LoggingOutInterceptor" id="logOutInterceptor" />
	<cxf:bus>
		<cxf:inInterceptors>
			<ref bean="logInInterceptor" />
		</cxf:inInterceptors>
		<cxf:outInterceptors>
			<ref bean="logOutInterceptor" />
		</cxf:outInterceptors>
	</cxf:bus>
	<jaxws:endpoint id="changeStudent" implementor="com.student.ChangeStudentDetailsImpl"
		address="/ChangeStudent" />
</beans>

Or you can use the following cxf.xml configuration using <cxf:features>

cxf.xml

<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  
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">
	<import resource="classpath:META-INF/cxf/cxf.xml" />
	<cxf:bus>
		<cxf:features>
			<cxf:logging />
		</cxf:features>
	</cxf:bus>
	<jaxws:endpoint id="changeStudent" implementor="com.student.ChangeStudentDetailsImpl"
		address="/ChangeStudent" />
</beans>

Note

In order to run the client, you need to add cxf libraries to class path, you can see this on below article

Create CXF Client Example

Now just run this below client

import org.apache.cxf.ext.logging.LoggingInInterceptor;
import org.apache.cxf.ext.logging.LoggingOutInterceptor;
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;

import com.student.ChangeStudentDetails;
import com.student.Student;

// Invoke CXF Server Side Logging

public final class StudentClient {

 
public static void main(String args[]) throws Exception {

   
JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();

    factory.setServiceClass
(ChangeStudentDetails.class);
    factory.setAddress
("http://localhost:8080/CXFTutorial/ChangeStudent?wsdl");
    ChangeStudentDetails client =
(ChangeStudentDetails) factory.create();
    Student student =
new Student();
    student.setName
("Rockey");
    Student changeName = client.changeName
(student);
    System.out.println
("Server said: " + changeName.getName());
    System.exit
(0);
 
}
}
Output

Here you can see the Tomcat server started and showing the request/response payloads

CXF Client Side Logging

Just run this below client you can see that we are adding the built in interceptors on client side

factory.getInInterceptors().add(new LoggingInInterceptor());
factory.getOutInterceptors().add(new LoggingOutInterceptor());
import org.apache.cxf.ext.logging.LoggingInInterceptor;
import org.apache.cxf.ext.logging.LoggingOutInterceptor;
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;

import com.student.ChangeStudentDetails;
import com.student.Student;

// Invoke CXF Client Side Logging

public final class StudentClient {

 
public static void main(String args[]) throws Exception {

   
JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();

    factory.setServiceClass
(ChangeStudentDetails.class);
    factory.setAddress
("http://localhost:8080/CXFTutorial/ChangeStudent?wsdl");
    factory.getInInterceptors
().add(new LoggingInInterceptor());
    factory.getOutInterceptors
().add(new LoggingOutInterceptor());
    ChangeStudentDetails client =
(ChangeStudentDetails) factory.create();
    Student student =
new Student();
    student.setName
("Rockey");
    Student changeName = client.changeName
(student);
    System.out.println
("Server said: " + changeName.getName());
    System.exit
(0);
 
}
}
Output

Here you can see that Eclipse console is showing request/response payloads
