Spring Boot Build Status

Spring Boot makes it easy to create Spring-powered, production-grade applications and services with absolute minimum fuss. It takes an opinionated view of the Spring platform so that new and existing users can quickly get to the bits they need.

You can use Spring Boot to create stand-alone Java applications that can be started using java -jar or more traditional WAR deployments. We also provide a command line tool that runs spring scripts.

Our primary goals are:

  • Provide a radically faster and widely accessible getting started experience for all Spring development

  • Be opinionated out of the box, but get out of the way quickly as requirements start to diverge from the defaults

  • Provide a range of non-functional features that are common to large classes of projects (e.g. embedded servers, security, metrics, health checks, externalized configuration)

  • Absolutely no code generation and no requirement for XML configuration

Installation and Getting Started

The reference documentation includes detailed installation instructions as well as a comprehensive ``getting started'' guide. Documentation is published in HTML, PDF and EPUB formats.

Here is a quick teaser of a complete Spring Boot application in Java:

import org.springframework.boot.*;
import org.springframework.boot.autoconfigure.*;
import org.springframework.web.bind.annotation.*;

public class Example {

	String home() {
		return "Hello World!";

	public static void main(String[] args) throws Exception {
		SpringApplication.run(Example.class, args);

Building from Source

You don’t need to build from source to use Spring Boot (binaries in repo.spring.io, but if you want to try out the latest and greatest, Spring Boot can be built with maven v3.0.5 or above. You also need JDK 1.7 (although Boot applications can run on Java 1.6).

$ mvn clean install
You may need to increase the amount of memory available to Maven by setting a MAVEN_OPTS environment variable with the value -Xmx512m -XX:MaxPermSize=128m

Also see CONTRIBUTING.adoc if you wish to submit pull requests, and in particular please fill out the Contributor’s Agreement before your first change however trivial. (Or if you filed such an agreement already for another project just mention that in your pull request.)


There are a number of modules in Spring Boot, here is a quick overview:


The main library providing features that support the other parts of Spring Boot, these include:

  • The SpringApplication class, providing static convenience methods that make it easy to write a stand-alone Spring Application. Its sole job is to create and refresh an appropriate Spring ApplicationContext

  • Embedded web applications with a choice of container (Tomcat or Jetty for now)

  • First class externalized configuration support

  • Convenience ApplicationContext initializers, including support for sensible logging defaults


Spring Boot can configure large parts of common applications based on the content of their classpath. A single @EnableAutoConfiguration annotation triggers auto-configuration of the Spring context.

Auto-configuration attempts to deduce which beans a user might need. For example, If HSQLDB is on the classpath, and the user has not configured any database connections, then they probably want an in-memory database to be defined. Auto-configuration will always back away as the user starts to define their own beans.


Starters are a set of convenient dependency descriptors that you can include in your application. You get a one-stop-shop for all the Spring and related technology that you need without having to hunt through sample code and copy paste loads of dependency descriptors. For example, if you want to get started using Spring and JPA for database access just include the spring-boot-starter-data-jpa dependency in your project, and you are good to go.


The Spring command line application compiles and runs Groovy source, making it super easy to write the absolute minimum of code to get an application running. Spring CLI can also watch files, automatically recompiling and restarting when they change.


Spring Boot Actuator provides additional auto-configuration to decorate your application with features that make it instantly deployable and supportable in production. For instance if you are writing a JSON web service then it will provide a server, security, logging, externalized configuration, management endpoints, an audit abstraction, and more. If you want to switch off the built in features, or extend or replace them, it makes that really easy as well.


Spring Boot Loader provides the secret sauce that allows you to build a single jar file that can be launched using java -jar. Generally you will not need to use spring-boot-loader directly, but instead work with the Gradle or Maven plugin.


Groovy samples for use with the command line application are available in spring-boot-cli/samples. To run the CLI samples type spring run <sample>.groovy from samples directory.

Java samples are available in spring-boot-samples and should be built with maven and run by invoking java -jar target/<sample>.jar. The following java samples are provided:


The spring.io site contains several guides that show how to use Spring Boot step-by-step:
