Jetty Server Sitzung ist Null

Ich versuche, ein Hallo Welt Jetty-Projekt (mit Jetty 9.3.6.v20151106) mit einem Servlet zu implementieren, die die Sitzung untersucht. Wenn mein Code jedoch ausgeführt wird, kann ich die Sitzung nicht sehen und keine Cookies speichern. Ich habe this stackoverflow Frage zur Hilfe bei der Fehlersuche und implementiert die einfache BaseServlet empfohlen, aber jedes Mal, wenn ich es BaseServlet Ausgänge "keine Sitzung". Fehle ich etwas Konfiguration?Jetty Server Sitzung ist Null

Hier ist meine HelloWorld.java Klasse:

package com.my.company; 

import org.eclipse.jetty.server.HttpConfiguration; 
import org.eclipse.jetty.server.HttpConnectionFactory; 
import org.eclipse.jetty.server.Server; 
import org.eclipse.jetty.server.ServerConnector; 
import org.eclipse.jetty.server.SessionManager; 
import org.eclipse.jetty.server.handler.ContextHandlerCollection; 
import org.eclipse.jetty.server.session.HashSessionIdManager; 
import org.eclipse.jetty.server.session.HashSessionManager; 
import org.eclipse.jetty.server.session.SessionHandler; 
import org.eclipse.jetty.servlet.ServletContextHandler; 
import org.eclipse.jetty.servlet.ServletHandler; 
import org.eclipse.jetty.servlet.ServletHolder; 

public class HelloWorld { 

public static void main(String[] args) throws Exception { 
    //Create the server 
    Server server = new Server(); 

    // Configure for Http 
    HttpConfiguration http_config = new HttpConfiguration(); 
    http_config.setSecureScheme("https"); 
    http_config.setSecurePort(8443); 
    http_config.setOutputBufferSize(32768); 

    ServerConnector http = new ServerConnector(server, 
      new HttpConnectionFactory(http_config)); 
    int http_port = 12043; 
    http.setPort(http_port); 
    http.setIdleTimeout(30000); 
    server.addConnector(http); 

    //Add ServletContextHandler 
    ServletContextHandler servletContextHandler = new ServletContextHandler(
      ServletContextHandler.SESSIONS); 
    servletContextHandler.setContextPath("/"); 

    SessionManager sessionManager = new HashSessionManager(); 
    sessionManager.setMaxInactiveInterval(60 * 15); //session time out of 15 minutes 
    HashSessionIdManager idManager = new HashSessionIdManager(); 
    sessionManager.getSessionCookieConfig().setName("JSESSIONID_" + Integer.toString(http_port)); 
    sessionManager.setSessionIdManager(idManager); 
    server.setSessionIdManager(idManager); 
    SessionHandler sessionHandler = new SessionHandler(sessionManager); 
    servletContextHandler.setSessionHandler(sessionHandler); 
    server.setHandler(servletContextHandler); 

    //Add BaseServlet 
    ServletHolder holder = new ServletHolder(new BaseServlet()); 
    servletContextHandler.addServlet(holder, "/*"); 

    //Start the server 
    server.start(); 
    System.out.println("SERVER DUMP AFTER START" + server.dump()); 

    // The use of server.join() the will make the current thread join and 
    // wait until the server is done executing. 
    // See http://docs.oracle.com/javase/7/docs/api/java/lang/Thread.html#join() 
    server.join(); 
    } 
}

Hier meine BaseServlet.java Klasse:

package com.my.company; 

import java.io.IOException; 
import java.io.PrintWriter; 
import java.util.Date; 

import javax.servlet.http.HttpServlet; 
import javax.servlet.http.HttpServletRequest; 
import javax.servlet.http.HttpServletResponse; 
import javax.servlet.http.HttpSession; 

public class BaseServlet extends HttpServlet { 
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws IOException { 
    boolean create = "true".equals(req.getParameter("create")); 

    HttpSession session = req.getSession(create); 
    if (create) { 
     session.setAttribute("created", new Date()); 
    } 

    PrintWriter pw = new PrintWriter(resp.getOutputStream()); 
    pw.println("Create = " + create); 
    if (session == null) { 
     pw.println("no session"); 
    } else { 
     pw.println("Session = " + session.getId()); 
     pw.println("Created = " + session.getAttribute("created")); 
    } 

    pw.flush(); 
    } 
}

mit den Leuten auf der Jetty Benutzer Nach dem Gespräch Mailing-Liste, geändert ich meinen Code zu werden:

public static void main(String[] args) throws Exception { 
// Create the server 
Server server = new Server(12043); 

// Add ServletContextHandler 
ServletContextHandler servletContextHandler = new ServletContextHandler(
ServletContextHandler.SESSIONS); 
servletContextHandler.setContextPath("/"); 

server.setHandler(servletContextHandler); 

// Add BaseServlet 
ServletHolder holder = new ServletHolder(new BaseServlet()); 
servletContextHandler.addServlet(holder, "/*"); 

// Start the server 
server.start(); 
System.out.println("SERVER DUMP AFTER START" + server.dump()); 

server.join(); 

}

Wo ist der Ausgang: Anfrage = Request (GET // localhost: 12043 /) @ 968bbe8 Response = HTTP/1.1 200 Datum: Do, 2. Juni 2016 13.00.04 GMT erstellen = false keine Sitzung

Das wird erwartet, da der Aufruf request.getSession (false) die Sitzung nicht erstellt. Es gibt es nur zurück, wenn es zuvor erstellt wurde.
