Tomcat自发设置cookie JSESSIONID

Question

I have a spring webapp running on tomcat. I never set any sessions in my code. There is only this line :

HttpSession session = httpServletRequest.getSession(false);
if( session != null )
{
     log.debug("session is not null");
}

These lines logs, session is not null , which makes no sense. I also checked, a cookie named JSESSIONID is being set. But as you can see above I give false enter code here argument to getSession . How is this possible ?

我错过了一个事实，除非您输入<% session=false %> jsp页面会创建一个会话。
