17.6. Logging Message Content
Overview
You can log the content of the messages that are sent between a service and a consumer. For example, you might want to log the contents of SOAP messages that are being sent between a service and a consumer.
Configuring message content logging
To log the messages that are sent between a service and a consumer, and vice versa, complete the following steps:
Adding the logging feature to an endpoint
Add the logging feature your endpoint's configuration as shown in Example 17.11, “Adding Logging to Endpoint Configuration”.
Example 17.11. Adding Logging to Endpoint Configuration
<jaxws:endpoint ...>
<jaxws:features>
<bean class="org.apache.cxf.feature.LoggingFeature"/>
</jaxws:features>
</jaxws:endpoint>
The example XML shown in Example 17.11, “Adding Logging to Endpoint Configuration” enables the logging of SOAP messages.
Adding the logging feature to a consumer
Add the logging feature your client's configuration as shown in Example 17.12, “Adding Logging to Client Configuration”.
Example 17.12. Adding Logging to Client Configuration
<jaxws:client ...>
<jaxws:features>
<bean class="org.apache.cxf.feature.LoggingFeature"/>
</jaxws:features>
</jaxws:client>
The example XML shown in Example 17.12, “Adding Logging to Client Configuration” enables the logging of SOAP messages.
Set logging to log INFO level messages
Ensure that the
logging.properties file associated with your service is configured to log INFO level messages, as shown in Example 17.13, “Setting the Logging Level to INFO”.
Example 17.13. Setting the Logging Level to INFO
.level= INFO java.util.logging.ConsoleHandler.level = INFO
Logging SOAP messages
To see the logging of SOAP messages modify the wsdl_first sample application located in the
InstallDir/samples/wsdl_first directory, as follows:
- Add the
jaxws:featureselement shown in Example 17.14, “Endpoint Configuration for Logging SOAP Messages” to thecxf.xmlconfiguration file located in the wsdl_first sample's directory:Example 17.14. Endpoint Configuration for Logging SOAP Messages
<jaxws:endpoint name="{http://apache.org/hello_world_soap_http}SoapPort" createdFromAPI="true"> <jaxws:properties> <entry key="schema-validation-enabled" value="true" /> </jaxws:properties> <jaxws:features> <bean class="org.apache.cxf.feature.LoggingFeature"/> </jaxws:features> </jaxws:endpoint> - The sample uses the default
logging.propertiesfile, which is located in theInstallDir/etcdirectory. Make a copy of this file and name itmylogging.properties. - In the
mylogging.propertiesfile, change the logging levels toINFOby editing the.leveland thejava.util.logging.ConsoleHandler.levelconfiguration properties as follows:.level= INFO java.util.logging.ConsoleHandler.level = INFO
- Start the server using the new configuration settings in both the
cxf.xmlfile and themylogging.propertiesfile as follows:Platform Command Windows start java -Djava.util.logging.config.file=%CXF_HOME%\etc\mylogging.properties demo.hw.server.ServerUNIX java -Djava.util.logging.config.file=$CXF_HOME/etc/mylogging.properties demo.hw.server.Server & - Start the hello world client using the following command:
Platform Command Windows java -Djava.util.logging.config.file=%CXF_HOME%\etc\mylogging.properties demo.hw.client.Client .\wsdl\hello_world.wsdlUNIX java -Djava.util.logging.config.file=$CXF_HOME/etc/mylogging.properties demo.hw.client.Client ./wsdl/hello_world.wsdl
The SOAP messages are logged to the console.
