Annotation Type AfterAction

@Retention(value=RUNTIME)
@Target(value=METHOD)
public @interface AfterAction

A method annotated with this annotation is invoked after the @Action method is invoked. There can be only one method with this annotation in a controller or interceptor. An @AfterAction method must accept no arguments, or accept only a RequestContext argument. Methods annotated with this annotation must not be annotated with @Action, @DefaultAction, or @InterceptedBy. An @AfterAction method must be public.

An @AfterAction method can return any return type, but only a View return type will have any significance. If a concrete View is returned, it overrides the View returned by the @Action method. However, if a null View is returned, then the View returned by the @Action method is used.

The following are valid uses of this annotation:

 @AfterAction
 public View doSomethingAfter() {
     return new View("after.jsp");
 }
 

 @AfterAction
 public View doSomethingAfter() {
     return null; // use the View returned by the @Action method
 }
 

 @AfterAction
 public void doSomethingAfter() {
     // do something after and use the View returned by the @Action method
 }
 

An @AfterAction method can be used either in a controller or in an interceptor class. For more information about interceptors, see InterceptedBy.
