QUESTION
I'm trying to implement Spring redis session in an existing Spring MVC (ver 5.1.6) application. In web.xml we have ContextLoaderListener, DispatcherServlet and contextConfigLocation are all defined.
After required dependencies are included and suggested code changes are done, i'm getting below error:
Caused by: java.lang.IllegalStateException: Cannot initialize context because there is already a root application context present - check whether you have multiple ContextLoader definitions in your web.xml!"}}*
As part of code changes i'm extending the class "AbstractHttpSessionApplicationInitializer",(from Spring session core library) which internally implements WebApplicationInitializer. Seems like that is trying to create another context and throwing the above error. We cannot avoid extending this class, as this does the job of registering redisHttpSession to context.
Most of the examples available are all with spring boot. So there they wouldn't have faced this issue.
Any solution, other than completely replacing web.xml and use only WebApplicationInitializer?
...ANSWER
Answered 2021-Mar-07 at 11:49Just want to provide an update. Instead of extending AbstractHttpSessionApplicationInitializer abtract class, i have taken a different approach by initializing bean RedisHttpSessionConfiguration thru XML bean definition.
This approach worked.
Followed the steps mentioned in the below thread; How to configure Spring sessions to work with Redis in xml?
Along with that we need to serialize the cookie as well;
QUESTION
So I'm basically using RedisHttpSession for session management. I've created this login API which stores the Staff object in the session when the login is successful. request.getSession().setAttribute("staff", staff); And in other APIs, I verify if a valid staff is logged in and if not I redirect them to the login page. Staff staff = (Staff) request.getSession().getAttribute("staff"); Now when I tested this whole scenario with Postman, it worked as expected but, I staged it on the server, and request.getSession().getId() is different in each request.
The other thing that I noticed was that when I was sending requests from Postman, I saw cookies being stored but there were no cookies on the browser.
Why is the sessionId different in each request? How do I solve this issue?
...ANSWER
Answered 2021-Jan-19 at 06:06HttpSession was creating a new SessionId every time because the cookie wasn't being stored in the browser. And to handle that, I created a new @Configuration:

Install RedisHttpSession
You can use RedisHttpSession like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the RedisHttpSession component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
