(Recommended learning: Introduction to java development)

Let’s introduce them separately:

1, Spring

Spring is an open source container framework that can take over components of the web layer, business layer, dao layer, and persistence layer, and can configure various beans and maintain the relationship between beans. Its core is Inversion of Control (IOC) and Aspect Orientation (AOP). Simply put, it is a layered lightweight open source framework.

2. SpringMVC

Spring MVC is a follow-up product of SpringFrameWork and has been integrated into Spring Web Flow. SpringMVC is a web layer mvc framework used to replace servlets (process | respond to requests, obtain form parameters, form verification, etc.).

(Video tutorial recommendation: java video tutorial)

SpringMVC is an open source framework for MVC. SpringMVC=struts2 spring. springMVC is equivalent to the integration of Struts2 plus Spring. .

3. SpringBoot

Springboot is a microservice framework that continues the core ideas of spring framework IOC and AOP, simplifying application development and deployment.

Spring Boot emerged to simplify the creation, running, debugging, deployment, etc. of Spring applications. Using it, you can focus on the development of Spring applications without paying too much attention to XML configuration. A bunch of dependency packages are provided, and dependency issues have been solved according to usage habits --->Habits are greater than conventions.
