What is Spring Boot?

Spring Boot is a Java-based framework that follows an opinionated default configuration and enables programmers to create "production-ready" apps quickly and easily. It is based on the Spring framework and offers a simpler approach to developing standalone, production-quality Spring-based apps. It is also well-supported by a large community of developers and provides integration with a variety of popular technologies and libraries, making it a flexible and versatile solution for a wide range of application development needs.

Spring Boot provides default configurations and conventions that can be easily overridden, as well as pre-packaged solutions for common tasks, such as embedded web servers, security, and data access. With Spring Boot, developers can launch their projects quickly and worry less about difficult setup and configuration processes. It is therefore perfect for creating small to medium-sized apps and for quickly prototyping new concepts.
