Spring installation configuration tutorial

1. Introduction to Spring

Spring is an open-source design-level framework. It solves the problem of loose coupling between the business logic layer and other layers, so it applies the interface-oriented programming idea throughout the entire system application. Spring is a lightweight Java development framework that emerged in 2003 and was created by Rod Johnson. In short, Spring is a layered JavaSE/EE full-stack (one-stop) lightweight open source framework.
