Spring is a comprehensive framework for building enterprise-level Java applications. It simplifies development by providing tools for dependency injection, aspect-oriented programming, transaction management, and web applications.
Spring Boot provides a good platform for Java developers to develop a stand-alone and production-grade spring application that you can just run. You can get started with minimum configurations without the need for an entire Spring configuration setup.
Spring Boot works on top of Spring and helps us write code with minimal configuration by providing built-in support for Tomcat web server, Maven build tool, and Docker.
