Spring Boot is an open-source Java-based framework used to create stand-alone, production-grade Spring-based applications that can be "just run". It is a convention-over-configuration solution for creating Spring applications with minimal amounts of configuration. Spring Boot is designed to simplify the configuration and setup process, allowing developers to focus more on writing code for their applications. Some key features of Spring Boot include:
-
Opinionated view: Spring Boot takes an opinionated view of the Spring platform and third-party libraries, so developers can get started with minimum fuss.
-
Minimal configuration: Most Spring Boot applications need minimal Spring configuration.
-
Programming languages: A Spring Boot application can be written using several programming languages, including Java and Kotlin.
-
Autoconfiguration: Spring Boot applications can autoconfigure third-party libraries and detected features found on the classpath using the @SpringBootApplication annotation, which combines three Spring-specific annotations: @SpringBootConfiguration, @EnableAutoConfiguration, and @ComponentScan.
-
Production-ready features: Spring Boot provides production-ready features such as metrics, health checks, and externalized configuration.
Spring Boot is particularly useful for software engineers developing web apps and microservices. It is designed to avoid complex XML configuration in Spring and to develop production-ready Spring applications in an easier way.
