Class ActionMappingParametersInterceptor

All Implemented Interfaces:
Serializable, ConditionalInterceptor, Interceptor

public class ActionMappingParametersInterceptor extends ParametersInterceptor

This interceptor sets all parameters from the action mapping, for this request, on the value stack. It operates exactly like ParametersInterceptor, only the parameters come from the ActionMapping, not the 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 ParameterNameAware interface in your actions. 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 ParametersInterceptor.isAcceptableName(String) method.

Example code:

 
 <action name="someAction" class="com.examples.SomeAction">
     <interceptor-ref name="mappingParams"/>
     <result name="success">good_result.ftl</result>
 </action>
