What is a Spring Framework?
Spring -- is a popular framework for building Java applications. It has a lot of modules, each designed to handle a specific task. They are combined into few different layers.
Img. 1 -- Spring layers
| Layer | Purpose |
|---|---|
| Core | Handling dependency injection, managing objects |
| Web | Building web applications |
| Data | Working with databases |
| AOP | Aspect oriented programming |
| Test | Testing spring components |
While the spring framework is powerfull, using it often involves a lot of configuration. For example, if you want to build a web app you might need to setup a web server, configure routing and manage dependencies manually. That's when Spring Boot comes in.
You can think of spring boot as a layer on top of the spring framework, that takes care of all of the setup.
