Here's the class. I'm assuming here that we'd create another Interceptor
if we want it to call a validate() method on the Action... If you don't
use this, you could just use the regular ValidationInterceptor.
public class DefaultWorkflowInterceptor implements Interceptor {
/**
* Called to let an interceptor clean up any resources it has
allocated.
*/
public void destroy() {
}
/**
* Called after an Interceptor is created, but before any requests
are processed using the intercept() methodName. This
* gives the Interceptor a chance to initialize any needed
resources.
*/
public void init() {
}
/**
* Allows the Interceptor to do some processing on the request
before and/or after the rest of the processing of the
* request by the DefaultActionInvocation or to short-circuit the
processing and just return a String return code.
*
* @param invocation
* @return
* @throws Exception
*/
public String intercept(ActionInvocation invocation) throws
Exception {
Action action = invocation.getAction();
if (action instanceof ValidationAware) {
ValidationAware validationAwareAction =
(ValidationAware)action;
if (validationAwareAction.hasErrors()) {
return Action.INPUT;
}
}
return invocation.invoke();
}
}
