小编use*_*114的帖子

我在servlet中成功创建了会话,我可以获得jsp的会话/会话属性,但不能在端点类中获取.我想在端点类中获取会话信息.请帮我解决一下这个.

我在eclipse中使用maven,我在appengine-web.xml中启用了会话

我读了一篇关于这个的文章,除了如何启用会话我什么都不懂.

该servlet用于检查是否已存在会话

public class FirstServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
public FirstServlet () {
    super();
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    service(request, response);
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    service(request, response);
}
@Override
protected void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    response.setContentType("text/html");
    HttpSession session=request.getSession(false);
    if (session != null) {
        String name = session.getAttribute("name");
        // do something
    } …
