What is Spring Framework? Nedir?
Spring is the most popular enterprise application framework in the Java ecosystem, enabling rapid development with Spring Boot.
Spring Framework was developed by Rod Johnson in 2003 as an alternative to J2EE complexity. Based on Dependency Injection and Aspect-Oriented Programming (AOP), Spring has become the standard in Java enterprise development. Spring Boot is the most important project in the Spring ecosystem. Automatic configuration, embedded servers (Tomcat, Jetty), starter dependencies, and production-ready features (metrics, health checks) enable rapid application development. The 'convention over configuration' approach minimizes configuration. The Spring ecosystem is extremely comprehensive: Spring MVC (web), Spring Data (database access), Spring Security (security), Spring Cloud (microservices), Spring Batch (batch processing), Spring Integration (system integration). Spring WebFlux provides reactive programming support. Used across a wide spectrum from the world's largest banks to e-commerce platforms, government agencies to healthcare systems, Spring is the clear leader in Java enterprise development.
