Spring Framework Ecosystem

Overview

Spring is the most widely-used Java application framework for building enterprise applications. It provides comprehensive infrastructure support for developing Java applications, with a focus on inversion of control (IoC), dependency injection (DI), aspect-oriented programming (AOP), and modular project structure.

The Spring ecosystem consists of multiple projects that build on the Spring Framework core:

• Spring Boot - Stand-alone, production-grade applications with auto-configuration and embedded servers
• Spring Framework - Core IoC container, AOP, web MVC, WebFlux, data access, testing
• Spring Security - Authentication, authorization, OAuth2, CSRF, session management
• Spring Data - Repository abstractions for JPA, MongoDB, Redis, JDBC, REST, and more
