Spring Boot is the starting point for building all Spring-based applications. Spring Boot is designed to get you up and running as quickly as possible, with a minimal upfront configuration of Spring.

- Get started in seconds using Spring Initializr
- Build anything - REST API, WebSocket, Web, Streaming, Tasks, and more
- Simplified Security
- Rich support for SQL and NoSQL
- Embedded runtime support - Tomcat, Jetty, and Undertow
- Developer productivity tools such as live reload and auto restart
- Curated dependencies that just work
- Production-ready features such as tracing, metrics and health status
- Works in your favorite IDE - Spring Tool Suite, IntelliJ IDEA and NetBeans
Spring Boot 2.0 requires Java 8 or later. Java 6 and 7 are no longer supported. It also requires Spring Framework 5.0

Spring Boot Features

  1. Create stand-alone Spring applications
  2. Embed Tomcat, Jetty or Undertow directly (no need to deploy WAR files)
  3. Provide opinionated 'starter' dependencies to simplify your build configuration
  4. Automatically configure Spring and 3rd party libraries whenever possible
  5. Provide production-ready features such as metrics, health checks, and externalized configuration
  6. Absolutely no code generation and no requirement for XML configuration
