如何从CXF输出获取拦截器的会话

Question

I have a cxf "in interceptor" bound to Receive phase that store data into session.

MyCxfInInterceptor (In interceptor)

public class MyCxfInInterceptor extends AbstractSoapInterceptor {
    public MyCxfInInterceptor() {
        super(Phase.RECEIVE);
    }
    public void handleMessage(SoapMessage message) throws Fault {
        HttpServletRequest request (HttpServletRequest)message.get(AbstractHTTPDestination.HTTP_REQUEST);
        HttpSession session = request.getSession(true);

        session.setAttribute("foo","bar");
    }
}

MyCxfOutInterceptor (Out interceptor)

public class MyCxfOutInterceptor extends AbstractSoapInterceptor {
      public MyCxfOutInterceptor() {
        super(Phase.SEND);
      }


      public void handleMessage(SoapMessage message) throws Fault {
        //TODO Retrieve data from session.
      }
    }

I want to retrieve theses data into my "out interceptor". How can i do it ?

I don't know how to retrieve session from HttpServletResponse. Maybe the session is not available anymore. Is there any other way to store & retrieve data?

Spring could be helpful?

You can use the Exchange , to exchange the data between in and out interceptor

In interceptor

public void handleMessage(SoapMessage message) throws Fault {
  message.getExchange().put("foo","bar");
}

Out interceptor

public void handleMessage(SoapMessage message) throws Fault {
  Object obj = message.getExchange().get("foo");
 }
