   99% Of Devs Don't Understand Spring Boot

   Spring Boot simplifies Java development by automating configuration and removing XML complexity, making it production-ready out of the box. Major companies like Netflix, Amazon, and Spotify rely on it to power massive-scale systems with billions of API calls daily. Modern versions support Kotlin, reactive programming through Spring WebFlux, and cloud-native deployments, making it more relevant than its outdated reputation suggests. The framework's strength lies in its reliability, comprehensive ecosystem, and ability to handle enterprise-scale workloads efficiently.

   Spring Framework 7 API Versioning Explained

   Spring Framework 7 introduces native API versioning support through a new version attribute in @RequestMapping annotations. The framework provides multiple versioning strategies including request header, path segment, query parameter, and media type parameter approaches. Developers can configure versioning either through annotation-based WebMvcConfigurer implementations or property-based configuration in application.properties. The feature includes built-in components for version resolution, parsing (supporting semantic versioning), validation, and deprecation handling to maintain backward compatibility while evolving APIs.
