🏗️ The Foundation: Spring Framework
The Spring Framework is a comprehensive, modular platform for building enterprise-level Java applications. Its core feature is Inversion of Control (IoC) and Dependency Injection (DI), which help manage the various components of your application.
-
Purpose: To provide a solid, flexible infrastructure for Java applications. It handles the “plumbing” so you can focus on business logic.
-
Configuration: Highly flexible but often requires manual setup. You need to explicitly define beans, dependencies, and configurations, which can be complex and time-consuming.
-
Deployment: Applications are traditionally packaged as WAR files and deployed to an external server like Apache Tomcat.
-
How to Think of It: It’s the flexible, modular framework that gives you complete control but requires more upfront work.
