Spring Framework and Spring Boot

The Spring Framework is a powerful and comprehensive programming and configuration model for modern Java-based enterprise applications, designed to simplify development by providing core features like Dependency Injection (DI) and Inversion of Control (IoC) to promote loosely coupled code. Spring Boot is an evolution built on top of the core Spring Framework that radically accelerates development by taking an opinionated "convention over configuration" approach, offering auto-configuration, starter dependencies, and embedded web servers. This allows developers to create stand-alone, production-grade Spring applications with minimal boilerplate code and setup, making it the de facto standard for building modern Java microservices and web applications.
