Most people do not understand the knowledge points of this "Springboot integration Redis case analysis" article, so the editor summarizes the following content, detailed content, clear steps, and has a certain reference value. I hope you can get something after reading this article. Let's take a look at this "Springboot integration Redis case analysis" article.

Dependency package

Org.springframework.boot spring-boot-starter-data-redis

Configuration file (application.properties)
