Spring Framework Overview
Spring is a powerful, lightweight framework designed for the Java platform. It simplifies Java development and promotes good design practices through Dependency Injection and aspect-oriented programming.
Core Container Features
The Spring Core Container provides essential functionality for bean instantiation and wiring. Its BeanFactory and ApplicationContext offer sophisticated means of configuring both simple and composite objects.
Aspect-Oriented Programming
Spring's AOP module provides a way to dynamically add cross-cutting concerns, like logging or security, without tangling with business logic, enabling cleaner code separation.
Data Access Framework
Spring's Data Access/Integration framework streamlines database operations. It provides a consistent data access approach, reducing boilerplate JDBC code and integrating with popular ORM tools.
Spring MVC Framework
Spring MVC stands for Model-View-Controller. It's a web module that provides a robust infrastructure for developing flexible and loosely coupled web applications.
Spring Boot Innovation
Spring Boot revolutionized Spring by offering a way to create stand-alone, production-grade applications with minimal configuration, embedding servers like Tomcat, Jetty, or Undertow directly.
Reactive Spring Surprise
Spring 5 introduced WebFlux for building reactive, non-blocking applications. It supports backpressure and runs on servers such as Netty, enabling scalability and faster response times.
