Java Spring session.getAttribute("test") is null

Question

I have a problem with HttpSession, I do not have it
I think I forget an Annotation or anything like this.
Do I need anywhere to do a session.create() ?

In UserController :

@Controller
public UserController{
    public ResponseHttp connection(User userSent, HttpSession session) {
        ResponseHttp responseHttp = new ResponseHttp();       

        //function to check login/mdp 
            if (check) {
                responseHttp.setSuccess(true);
                responseHttp.setMessage("Connection success");
                //some code 
               //
               //
               session.setAttribute("userId", 1); // this is an example
               System.out.println(session.getAttribute("userId")) // return 1
               return responseHttp;
            }
        }

        responseHttp.setSuccess(false);
        responseHttp.setMessage("Connection failed");

        return responseHttp;
    }
}

In another controller :

@Controller
public class MyController{
    public void test(HttpSession session){
        System.out.println(session.getAttribute("userId")) ; // return null
    }
}

UPDATE 25-06-2017

I tried to inject @HttpSession in both controllers At connection I check the session like that :

if(httpSession.isNew()){
    System.out.println("New") // ok return new !
    System.out.println(httpSession.getId()); // A87AC018FD8DDA33B023FAA6C1C2D71C
}

In the other controller

if(httpSession.isNew()){
    System.out.println("New") //  it's returning new again
    System.out.println(httpSession.getId()); //  2FE08FB68EA53F7FEBB8143CFEE6A9EB
}else{
    System.our.println("not new")
}

Question: Why is not the same session ?
