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.
