Difference Between Spring and Spring Boot | Spring Framework vs. Spring Boot

In this video, we will learn the differences between Spring Framework and Spring Boot in Java. This is one of the frequently asked interview questions in Java interviews for beginners. The Spring Framework is an open-source framework for creating enterprise-level Java applications. It provides comprehensive infrastructure support, allowing developers to focus on building robust applications without worrying about underlying infrastructure problems like transaction management, logging, and security. Central to the Spring Framework is its Inversion of Control (IoC) container, which is responsible for managing Java object lifecycles, dependencies (via Dependency Injection), and much more. Spring Boot is an extension of the Spring Framework designed to simplify the initial setup and development of new Spring applications by providing defaults and eliminating boilerplate configuration. Spring Boot Main Features Here are the main features of Spring Boot, each described in one line: Auto Configuration: Automatically configures your application based on the included libraries. Standalone: Enables building production-ready standalone applications with embedded servers like Tomcat. Production Ready: Provides built-in health checks and metrics via Spring Boot Actuator. No Code Generation: Enhances existing code without generating additional code artifacts. Opinionated Defaults: Provides out-of-the-box default configurations to speed up development. Environment-specific Configuration: Easily manages application settings for different environments. Command Line Interface (CLI): Allows running Groovy scripts, making prototyping and scripting simple. Embedded Servers: No need for external server setup, comes with embedded Tomcat, Jetty, or Undertow. Spring Boot Initializr: Web-based tool to bootstrap new Spring Boot projects. Microservices Ready: Easily integrable with Spring Cloud, making microservices architecture development a breeze.
