Spring

What is Spring ?

Spring is a popular, open-source Java-based framework used to create enterprise-level applications. It provides a comprehensive programming and configuration model that simplifies Java development. At its core, Spring focuses on dependency injection and inversion of control (IoC), providing an abstraction over Java's complexity.

Core goals of Spring

  • Simplify Java development.
  • Promote loosely coupled and testable code.
  • Offer modularity through different projects (Spring Data, Spring Security, Spring MVC, etc.).

Ecosystem Overview

The Spring ecosystem consists of various projects for different use cases:

  • Core Spring Framework – Foundation for building Java applications with dependency injection and IoC.
  • Spring Boot – Simplifies the creation of stand-alone, production-ready Spring applications.
  • Spring MVC – Web framework for building RESTful APIs and web applications.
  • Spring Security – Framework for authentication and authorization.
  • Spring Data – Simplifies interaction with databases.
  • Spring Cloud – Toolkit for building cloud-native, microservices applications.
