What is Spring Boot?

Spring Boot is an open-source framework that is based on the popular Spring framework for building stand-alone, production-grade applications. It provides a fast and easy way to create applications that are powered by the Spring framework.

Spring Boot simplifies the configuration and deployment of Spring-based applications by providing a set of opinionated defaults and auto-configuration capabilities that minimize boilerplate code and reduce development time. It also includes embedded web servers, which means that developers can build web applications without having to deploy to a separate web server.

Some of the key features of Spring Boot include:

  • Auto-configuration: Spring Boot automatically configures the application based on the classpath, reducing the need for manual configuration.
  • Embedded servers: Spring Boot includes embedded Tomcat, Jetty, and Undertow servers, which allow you to build web applications without the need for a separate web server.
  • Starter POMs: Spring Boot provides a set of starter POMs that simplify the configuration of common dependencies, such as databases and messaging systems.
  • Actuator: Spring Boot includes a set of production-ready features, such as monitoring and health checks, through the Spring Boot Actuator.

Overall, Spring Boot makes it easier and faster to build Spring-based applications, while still providing the flexibility and power of the underlying Spring framework.
