struts 2 passing parameter to interceptor

[shashi wagh]

In my struts 2 application I have a LoginInterceptor
I want to pass some parameter through the struts.xml file
How can I pass the parameter to the interceptor.
In other words I want the parameter which I send to the action from struts.xml

e.g.

 
<action name="cancelBookingDtls" class="CancelRetrieveBookingAction">
        <param name="actionPerformed">viewBookingDtls</param>
<param name="menuId">14</param>
<result type="tiles">CancelRetrieveBooking</result>
<result type="tiles" name="login">Unauthorized</result>
</action>

I want menuId in interception which I have configure for this action.

How do I get the value In interceptor.

I have already try for getter setter for menuId in interceptor.

I think these parameters will get places into the request and can be retrieved from there. Also, if you make bean properties for these values in your action class I think they will be placed into the action class as well.

I am getting value in action class by getter and setter
but I want the value in Interceptor

even I have use

String menuId = request.getParameter( "menuID");

in my Interceptor.

[Tom Rispoli]

Your intercept method should recieve a parameter of type ActionInvocation. If you call .getAction on this object you can get a reference to your action class and then you can get the values from there.

Struts 2.0.11 version

MyInterceptor implements Interceptor , StrutsStatics{

public String intercept(ActionInvocation invocation) throws Exception {
final ActionContext context = invocation.getInvocationContext ();
HttpServletRequest request = (HttpServletRequest) context.get(HTTP_REQUEST);
Map params = request.getParameterMap();
//Retrieve the map and check..
for (Iterator iterator = params.keySet().iterator(); iterator.hasNext();) {
String key = (String) iterator.next();
String[] obj = (String[])(params.get(key));
if(obj.length>0)
System.out.println(key+"<>"+obj[0]);


}

}

Hi Anirban,

Thanks for your reply...

I followed the way that i mentioned below.

public String intercept(ActionInvocation ai) throws Exception {
            ActionConfig config = ai.getProxy().getConfig();
            Map parameters = config.getParams();
            String roles = (String)parameters.get("roles");
            System.out.println("ROLES11: " + roles);
            Map session = ActionContext.getContext().getSession();
            String userEmail = (String)session.get("USER_EMAIL");
            
            String result = ai.invoke();

            System.out.println("RESULT: " + result);
            return result;
    }

Raju
