How to use Redis and Groovy to develop distributed session storage functions

How to use Redis and Groovy to develop distributed session storage functions Introduction: In web application development, session management is a very important component. A session is the interaction between a user and an application and needs to be maintained throughout the user's visit. The traditional session processing method is to store session data in the server-side memory, but this method cannot achieve session sharing in a cluster environment. As a high-performance distributed cache database, Redis can provide a solution for distributed session storage.
