Timer Interceptor

This interceptor logs the amount of time in milliseconds. In order for this interceptor to work properly, the logging framework must be set to at least the INFO level. This interceptor relies on the Commons Logging API to report its execution-time value.

Parameters

The parameters above enables us to log all action execution times in our own logfile.

Extending the Interceptor

This interceptor can be extended to provide custom message format. Users should override the invokeUnderTiming method.

Examples

 <!-- records only the action's execution time -->
 <action name="someAction" class="com.examples.SomeAction">
     <interceptor-ref name="completeStack"/>
     <interceptor-ref name="timer"/>
     <result name="success">good_result.ftl</result>
 </action>

 <!-- records action's execution time as well as other interceptors-->
 <action name="someAction" class="com.examples.SomeAction">
     <interceptor-ref name="timer"/>
     <interceptor-ref name="completeStack"/>
     <result name="success">good_result.ftl</result>
 </action>
