httpsession

问题 I need to access the domain class User of the current session. The following code works: class RatingController { def rate = { def rating = params.rating def artist = Artist.get( params.id ) def user = User.get(1) user.addToRatings(new Rating(artist:artist, rating:rating)) user.save() render(template: "/artist/rate", model: [artist: artist, rating: rating]) } } But instead of explicitly get the user with ID equal 1 (User.get(1)) I need to access the user of the current session. I tried the

问题 I googled a lot for this problem before posting this question and Accessing HttpSession from HttpServletRequest in a Web Socket @ServerEndpoint is one of the best Questions/Answers I was able to found, but it appears to not solve my problem. I was able to access HttpSession from websocket in this way, but I can't access the same CDI session bean instances as from normal HTTP requests. I tried to store in session the HttpSessionContextImpl Weld instance too and tried to use it on WebSocket

问题 I have three simple HttpServlet classes in my JSP project, "LoginServlet", "LogoutServlet" and "ProfileServlet". LoginServlet: log in user by setting "name" attribute to session LogoutServlet: log out user and invalidate session ProfileServlet: display user welcome info if user has logged in The last two servlets are as below that I reckon are problematic. @SuppressWarnings("serial") public class LogoutServlet extends HttpServlet { protected void doGet(HttpServletRequest request,

问题 I want to invalidate sessions of users based on some Event. I store their sessionID, how to get their HttpSession from this ID? The HttpSessionContext class is deprecated with no replacement. 回答1: Servlet 2.2 specifically deprecated this for security reasons so there shouldn't be any official way to do this. Not recommended but you can can try to use Manager.findSession() if you use Tomcat. I just removed HttpSession from my application. It's really hard to keep sessions in sync when many

问题 I am trying to implement a simple servlet which uses a HTTP session in an embedded jetty (7.3.0 v20110203) container. To start jetty I use the following code: Server server = new Server(12043); ServletContextHandler handler = new ServletContextHandler(ServletContextHandler.SESSIONS); handler.setContextPath("/"); server.setHandler(handler); ServletHolder holder = new ServletHolder(new BaseServlet()); handler.addServlet(holder, "/*"); server.start(); server.join(); The servlet acquires a

问题 I have a dynamic web application in Java EE with JSF, Facelets, Richfaces. My pages are all xhtml pages. So JSTL isn't working in it. For my account pages and all other private pages to be reachable, I want to test if the user got connected, so if the attribute session in HttpSession is not null. If it's null, the user gets redirected in the welcome page. I tried in my xhtml page : <jstl:if test="${sessionScope['session']==null}"> <jstl redirect...> </jstl:if>--> but as it's not jsp page it

问题 In my grails application, I have implemented the interface HttpSessionListener to listen for session creation as given below: class MyHttpSessionListener implements HttpSessionListener { public void sessionCreated(HttpSessionEvent event) { log.info "***************** Session created: id= ${event.getSession()?.id}" } } Now, I would like to log the IP address that is responsible for the session creation . How can I do that? 回答1: you can access the RequestContextHolder and get the value String

问题 I have a very simple Servlet and a very simple HttpSessionListener: @WebServlet("/HelloWorld") public class HelloWorld extends HttpServlet { private static final long serialVersionUID = 1L; @Override public void init(ServletConfig config) throws ServletException { super.init(config); getServletContext().setAttribute("applicationHits", new AtomicInteger(0)); } protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { System.out
