Maven Jetty服务器&x27；s会话为空

maven session jetty

Maven Jetty服务器&x27；s会话为空,maven,session,jetty,Maven,Session,Jetty,我正在尝试用一个servlet来实现hello world Jetty项目（使用Jetty 9.3.6.v20151106），该servlet查看会话。但是，当我的代码运行时，我无法看到会话或存储任何cookie。我研究了stackoverflow问题以帮助进行故障排除并实现了推荐的简单BaseServlet，但每次运行它时，BaseServlet都会输出“无会话”。我是否缺少一些配置下面是我的HelloWorld.java类： package com.my.company; import

我正在尝试用一个servlet来实现hello world Jetty项目（使用Jetty 9.3.6.v20151106），该servlet查看会话。但是，当我的代码运行时，我无法看到会话或存储任何cookie。我研究了stackoverflow问题以帮助进行故障排除并实现了推荐的简单BaseServlet，但每次运行它时，BaseServlet都会输出“无会话”。我是否缺少一些配置

在与Jetty用户邮件列表上的人交谈后，我将代码修改为：

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();

}

其中输出为：Request=Request（GET//localhost:12043/）@968bbe8 响应=HTTP/1.1200 日期：2016年6月2日星期四格林威治标准时间13:00:04 Create=false 没有会议

这是预期的，因为call request.getSession（false）不会创建会话。它仅在先前已创建会话时返回会话
