Following should give session id in jsp
以下应该在jsp中给出会话ID
If you have EL enabled in your container, you can do it without the JSTL tag - ie just
如果您在容器中启用了 EL，则可以在没有 JSTL 标记的情况下执行此操作 - 即只需
<c:out value="${pageContext.session.id}"/>
or An alternative for containers without EL:
或 没有 EL 的容器的替代方案：
<%= session.getId() %>
Example to get Cookies is as :
获取 Cookie 的示例如下：
<%
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;
}
}
}
%>
