推荐答案

以下应在jsp中提供会话ID

Following should give session id in jsp

如果您在容器中启用了EL，则可以在不使用JSTL标签的情况下进行操作-即

If you have EL enabled in your container, you can do it without the JSTL tag - ie just

<c:out value="${pageContext.session.id}"/>

或没有EL的容器的替代方案:

or An alternative for containers without EL:

<%= session.getId() %>

获取Cookie的示例如下:

Example to get Cookies is as :

<%
String cookieName = "username";
Cookie cookies [] = request.getCookies ();
Cookie myCookie = null;
if (cookies != null){
  for (int i = 0; i < cookies.length; i++) {
    if (cookies [i].getName().equals (cookieName)){
      myCookie = cookies[i];
      break;
    }
  }
}
%>
