如何通过servlet将http会话值传递给普通类

Question

我希望将HttpSession中的Servlet值传递给普通类。

Answer 1

只需将其传递给该班级。

// The class that use the session
public class UsingSession {
    private HttpSession session;

    public UsingSession(HttpSession session) {
        this.session = session;
    }

    ....
}


// In your servlet

...
UsingSession x = new UsingSession(httpServletRequest.getSession());
