How to restore application session after restarting tomcat?

Question

Java

When you restart tomcat or install a new version of the application, sessions are reset and users have to log in again, which is not very convenient. How can I save the session in the database and then restore it? The application uses Spring MVC, MySQL database and communication with it goes through JDBC

Answer 1

very handy topic: spring-session-data-redis
docs.spring.io/spring-session/docs/1.0.2.RELEASE/r...
for storing cat sessions in redis.
even if redis fails, you can see how spring serializes the session =)
