CDI注入Servlet无法正常工作

Question

I have a Controller with a producer.

@Named
@SessionScoped
public class UserController{

    private User user;

    //other methods

    @Produces
    @User
    public User produceUser() {
        return user;
    }
}

If I inject the user into a Servlet, I get always the same user(I compared the object IDs) - also in different sessions. If I inject the User in a CDI Bean, it's working and I get the user of the current session.

Answer 1

UserController is session-scoped, but the producer is not. Ie the producer has @Dependent scope, so the User bean gets injected once when the servlet is initialized.

Try adding @SessionScoped to your producer method.
