This interceptor sets all parameters from the action mapping, for this request, on the value stack. It operates exactly like {@link ParametersInterceptor}, only the parameters come from the {@link ActionMapping}, not the {@link ActionContext#getParameters()} method.
Interceptor parameters: - ordered - set to true if you want the top-down property setter behaviour
Extending the interceptor: The best way to add behavior to this interceptor is to utilize the {@link com.opensymphony.xwork2.interceptor.ParameterNameAware} interface in youractions. However, if you wish to apply a global rule that isn't implemented in your action, then you could extend this interceptor and override the {@link #acceptableName(String)} method.
Example code: <action name="someAction" class="com.examples.SomeAction"> <interceptor-ref name="mappingParams"/> <result name="success">good_result.ftl</result> </action>
