THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
A PreResultListener can affect an action invocation between the interceptor/action phase and the result phase. Typical uses include switching to a different Result or somehow modifying the Result or Action objects before the Result executes.
Examples
A PreResultListener can be added by an Action or an Interceptor.
By an Action
public class MyAction extends ActionSupport { ... public String execute() throws Exception { ActionInvocation invocation = ActionContext.getContext().getActionInvocation(); invocation.addPreResultListener(new PreResultListener() { public void beforeResult(ActionInvocation invocation, String resultCode) { // perform operation necessary before Result execution } }); } ... }
By an Interceptor
public class MyInterceptor extends AbstractInterceptor { ... public String intercept(ActionInvocation invocation) throws Exception { invocation.addPreResultListener(new PreResultListener() { public void beforeResult(ActionInvocation invocation, String resultCode) { // perform operation necessary before Result execution } }); } ... }
