spring httpsession和tomcat session之间的区别

Question

Is there any difference/correlation between spring httpsession and Tomcat session?

I have read Tomcat documentation but still I don't understand how it is related to deployed web apps.

Answer 1

No , they refer to the same things. You can think that Tomcat is responsible for creating and managing the actual session instance.

When a web app deployed on Tomcat need to access the session , it will ask Tomcat to give it by HttpServletRequest#getSession() .
