Question

我正在尝试在我的一个控制器中创建一个新的Session。一切正常，直到我在web.xml中添加了一个监听器您可以看到以下是响应。我试过谷歌搜索但没有发现任何东西。实际上我正在尝试创建一个新的会话，如果一个不存在。请帮助！

    <listener>
         <listener-class>org.springframework.security.web.session.HttpSessionEventPublisher</listener-class>
    </listener>

我的Java代码片段如下：

    HttpSession currentSession = null;
    currentSession = httpRequest.getSession(false);
    if(currentSession != null)
    {
        logger.info("No Session object found in context!");
        currentSession.setAttribute("NAME", seller.getSellerName());
        currentSession.setAttribute("EMAIL", seller.getEmail());
        currentSession.setAttribute("TOKEN", seller.getSsoToken());
    }
    else
    {
        logger.info("Creating a new Session Object!");
        currentSession = httpRequest.getSession(true);
        currentSession.setAttribute("NAME", seller.getSellerName());
        currentSession.setAttribute("EMAIL", seller.getEmail());
        currentSession.setAttribute("TOKEN", seller.getSsoToken());
    }
