= Getting started

[partintro]
--
If you're just getting started with Spring Boot, or 'Spring' in general, this is the section
for you! Here we answer the basic '"`what?`"', '"`how?`"' and '"`why?`"' questions. You'll
find a gentle introduction to Spring Boot along with installation instructions.
We'll then build our first Spring Boot application, discussing some core principles as
we go.
--


[[getting-started-introducing-spring-boot]]
== Introducing Spring Boot
Spring Boot makes it easy to create stand-alone, production-grade Spring based
Applications that you can "`just run`". We take an opinionated view of the Spring
platform and third-party libraries so you can get started with minimum fuss. Most Spring
Boot applications need very little Spring configuration.

You can use Spring Boot to create 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.



[[getting-started-system-requirements]]
== System Requirements
Spring Boot {spring-boot-version} requires http://www.java.com[Java 6] and Spring
Framework 4.1.3 or above. Explicit build support is provided for Maven (3.2+) and
Gradle (1.12+).

TIP: Although you can use Spring Boot with Java 6, we generally recommend Java 8 if at
all possible.

=== Servlet containers
The following embedded servlet containers are supported out of the box:

|===
|Name |Servlet Version |Java Version

|Tomcat 8
|3.1
|Java 7+

|Tomcat 7
|3.0
|Java 6+

|Jetty 9
|3.1
|Java 7+

|Jetty 8
|3.0
|Java 6+

|Undertow 1.1
|3.1
|Java 7+
|===

You can also deploy Spring Boot applications to any Servlet 3.0+ compatible container.



[[getting-started-installing-spring-boot]]
== Installing Spring Boot
Spring Boot can be used with "`classic`" Java development tools or installed as a command
line tool. Regardless, you will need http://www.java.com[Java SDK v1.6] or higher. You
should check your current Java installation before you begin:

[indent=0]
----
	$ java -version
----

If you are new to Java development, or if you just want to experiment with Spring Boot
you might want to try the <<getting-started-installing-the-cli, Spring Boot CLI>> first,
otherwise, read on for "`classic`" installation instructions.

TIP: Although Spring Boot is compatible with Java 1.6, if possible, you should consider
using the latest version of Java.



[[getting-started-installation-instructions-for-java]]
=== Installation instructions for the Java developer
You can use Spring Boot in the same way as any standard Java library. Simply include the
appropriate `+spring-boot-*.jar+` files on your classpath. Spring Boot does not require
any special tools integration, so you can use any IDE or text editor; and there is
nothing special about a Spring Boot application, so you can run and debug as you would
any other Java program.

Although you _could_ just copy Spring Boot jars, we generally recommend that you use a
build tool that supports dependency management (such as Maven or Gradle).



[[getting-started-maven-installation]]
==== Maven installation
Spring Boot is compatible with Apache Maven 3.2 or above. If you don't already have Maven
installed you can follow the instructions at http://maven.apache.org.

TIP: On many operating systems Maven can be installed via a package manager. If you're an
OSX Homebrew user try `brew install maven`. Ubuntu users can run
`sudo apt-get install maven`.

Spring Boot dependencies use the `org.springframework.boot` `groupId`. Typically your
Maven POM file will inherit from the `spring-boot-starter-parent` project and declare
dependencies to one or more <<using-spring-boot.adoc#using-boot-starter-poms, "`Starter
POMs`">>. Spring Boot also provides an optional
<<build-tool-plugins.adoc#build-tool-plugins-maven-plugin, Maven plugin>> to create
executable jars.

Here is a typical `pom.xml` file:

[source,xml,indent=0,subs="verbatim,quotes,attributes"]
----
	<?xml version="1.0" encoding="UTF-8"?>
	<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
		xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
		<modelVersion>4.0.0</modelVersion>

		<groupId>com.example</groupId>
		<artifactId>myproject</artifactId>
		<version>0.0.1-SNAPSHOT</version>

		<!-- Inherit defaults from Spring Boot -->
		<parent>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-parent</artifactId>
			<version>{spring-boot-version}</version>
		</parent>

		<!-- Add typical dependencies for a web application -->
		<dependencies>
			<dependency>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-starter-web</artifactId>
			</dependency>
		</dependencies>

		<!-- Package as an executable jar -->
		<build>
			<plugins>
				<plugin>
					<groupId>org.springframework.boot</groupId>
					<artifactId>spring-boot-maven-plugin</artifactId>
				</plugin>
			</plugins>
		</build>

ifeval::["{spring-boot-repo}" != "release"]
		<!-- Add Spring repositories -->
		<!-- (you don't need this if you are using a .RELEASE version) -->
		<repositories>
			<repository>
				<id>spring-snapshots</id>
				<url>http://repo.spring.io/snapshot</url>
				<snapshots><enabled>true</enabled></snapshots>
			</repository>
			<repository>
				<id>spring-milestones</id>
				<url>http://repo.spring.io/milestone</url>
			</repository>
		</repositories>
		<pluginRepositories>
			<pluginRepository>
				<id>spring-snapshots</id>
				<url>http://repo.spring.io/snapshot</url>
			</pluginRepository>
			<pluginRepository>
				<id>spring-milestones</id>
				<url>http://repo.spring.io/milestone</url>
			</pluginRepository>
		</pluginRepositories>
endif::[]
	</project>
----

TIP: The `spring-boot-starter-parent` is a great way to use Spring Boot, but it might
not be suitable all of the time. Sometimes you may need to inherit from a different
parent POM, or you might just not like our default settings. See
<<using-boot-maven-without-a-parent>> for an alternative solution that uses an `import`
scope.



[[getting-started-gradle-installation]]
==== Gradle installation
Spring Boot is compatible with Gradle 1.12 or above. If you don't already have Gradle
installed you can follow the instructions at http://www.gradle.org/.

Spring Boot dependencies can be declared using the `org.springframework.boot` `group`.
Typically your project will declare dependencies to one or more
<<using-spring-boot.adoc#using-boot-starter-poms, "`Starter POMs`">>. Spring Boot
provides a useful <<build-tool-plugins.adoc#build-tool-plugins-gradle-plugin, Gradle plugin>>
that can be used to simplify dependency declarations and to create executable jars.

.Gradle Wrapper
****
The Gradle Wrapper provides a nice way of "`obtaining`" Gradle when you need to build a
project. It's a small script and library that you commit alongside your code to bootstrap
the build process. See http://www.gradle.org/docs/current/userguide/gradle_wrapper.html
for details.
****

Here is a typical `build.gradle` file:

[source,groovy,indent=0,subs="verbatim,attributes"]
----
	buildscript {
		repositories {
			jcenter()
ifndef::release[]
			maven { url "http://repo.spring.io/snapshot" }
			maven { url "http://repo.spring.io/milestone" }
endif::release[]
		}
		dependencies {
			classpath("org.springframework.boot:spring-boot-gradle-plugin:{spring-boot-version}")
		}
	}

	apply plugin: 'java'
	apply plugin: 'spring-boot'

	jar {
		baseName = 'myproject'
		version =  '0.0.1-SNAPSHOT'
	}

	repositories {
		jcenter()
ifndef::release[]
		maven { url "http://repo.spring.io/snapshot" }
		maven { url "http://repo.spring.io/milestone" }
endif::release[]
	}

	dependencies {
		compile("org.springframework.boot:spring-boot-starter-web")
		testCompile("org.springframework.boot:spring-boot-starter-test")
	}
----



[[getting-started-installing-the-cli]]
=== Installing the Spring Boot CLI
The Spring Boot CLI is a command line tool that can be used if you want to quickly
prototype with Spring. It allows you to run http://groovy.codehaus.org/[Groovy] scripts,
which means that you have a familiar Java-like syntax, without so much boilerplate code.

You don't need to use the CLI to work with Spring Boot but it's definitely the quickest
way to get a Spring application off the ground.



[[getting-started-manual-cli-installation]]
==== Manual installation
You can download the Spring CLI distribution from the Spring software repository:

* http://repo.spring.io/{spring-boot-repo}/org/springframework/boot/spring-boot-cli/{spring-boot-version}/spring-boot-cli-{spring-boot-version}-bin.zip[spring-boot-cli-{spring-boot-version}-bin.zip]
* http://repo.spring.io/{spring-boot-repo}/org/springframework/boot/spring-boot-cli/{spring-boot-version}/spring-boot-cli-{spring-boot-version}-bin.tar.gz[spring-boot-cli-{spring-boot-version}-bin.tar.gz]

Cutting edge http://repo.spring.io/snapshot/org/springframework/boot/spring-boot-cli/[snapshot distributions]
are also available.

Once downloaded, follow the {github-raw}/spring-boot-cli/src/main/content/INSTALL.txt[INSTALL.txt]
instructions from the unpacked archive. In summary: there is a `spring` script
(`spring.bat` for Windows) in a `bin/` directory in the `.zip` file, or alternatively you
can use `java -jar` with the `.jar` file (the script helps you to be sure that the
classpath is set correctly).



[[getting-started-gvm-cli-installation]]
==== Installation with GVM
GVM (the Groovy Environment Manager) can be used for managing multiple versions of
various Groovy and Java binary packages, including Groovy itself and the Spring Boot CLI.
Get `gvm` from http://gvmtool.net and install Spring Boot with

[indent=0,subs="verbatim,quotes,attributes"]
----
	$ gvm install springboot
	$ spring --version
	Spring Boot v{spring-boot-version}
----

If you are developing features for the CLI and want easy access to the version you just
built, follow these extra instructions.

[indent=0,subs="verbatim,quotes,attributes"]
----
	$ gvm install springboot dev /path/to/spring-boot/spring-boot-cli/target/spring-boot-cli-{spring-boot-version}-bin/spring-{spring-boot-version}/
	$ gvm use springboot dev
	$ spring --version
	Spring CLI v{spring-boot-version}
----

This will install a local instance of `spring` called the `dev` instance inside your gvm
repository. It points at your target build location, so every time you rebuild Spring
Boot, `spring` will be up-to-date.

You can see it by doing this:

[indent=0,subs="verbatim,quotes,attributes"]
----
	$ gvm ls springboot

	================================================================================
	Available Springboot Versions
	================================================================================
	> + dev
	* {spring-boot-version}

	================================================================================
	+ - local version
	* - installed
	> - currently in use
	================================================================================
----



[[getting-started-homebrew-cli-installation]]
==== OSX Homebrew installation
If you are on a Mac and using http://brew.sh/[Homebrew], all you need to do to install
the Spring Boot CLI is:

[indent=0]
----
	$ brew tap pivotal/tap
	$ brew install springboot
----

Homebrew will install `spring` to `/usr/local/bin`.

NOTE: If you don't see the formula, your installation of brew might be out-of-date.
Just execute `brew update` and try again.



[[getting-started-macports-cli-installation]]
==== MacPorts installation
If you are on a Mac and using http://www.macports.org/[MacPorts], all you need to do to
install the Spring Boot CLI is:

[indent=0]
----
	$ sudo port install spring-boot-cli
----



[[getting-started-cli-command-line-completion]]
==== Command-line completion
Spring Boot CLI ships with scripts that provide command completion for
http://en.wikipedia.org/wiki/Bash_%28Unix_shell%29[BASH] and
http://en.wikipedia.org/wiki/Zsh[zsh] shells. You can `source` the script (also named
`spring`) in any shell, or put it in your personal or system-wide bash completion
initialization. On a Debian system the system-wide scripts are in `/shell-completion/bash`
and all scripts in that directory are executed when a new shell starts. To run the script
manually, e.g. if you have installed using `GVM`

[indent=0]
----
	$ . ~/.gvm/springboot/current/shell-completion/bash/spring
	$ spring <HIT TAB HERE>
	  grab  help  jar  run  test  version
----

NOTE: If you install Spring Boot CLI using Homebrew or MacPorts, the command-line
completion scripts are automatically registered with your shell.



[[getting-started-cli-example]]
==== Quick start Spring CLI example
Here's a really simple web application that you can use to test your installation. Create
a file called `app.groovy`:

[source,groovy,indent=0,subs="verbatim,quotes,attributes"]
----
	@RestController
	class ThisWillActuallyRun {

		@RequestMapping("/")
		String home() {
			"Hello World!"
		}

	}
----

Then simply run it from a shell:

[indent=0]
----
	$ spring run app.groovy
----

NOTE: It will take some time when you first run the application as dependencies are
downloaded. Subsequent runs will be much quicker.

Open http://localhost:8080 in your favorite web browser and you should see the following
output:

[indent=0]
----
	Hello World!
----



[[getting-started-upgrading-from-an-earlier-version]]
=== Upgrading from an earlier version of Spring Boot
If you are upgrading from an earlier release of Spring Boot check the "`release notes`"
hosted on the {github-wiki}[project wiki]. You'll find upgrade instructions along with
a list of "`new and noteworthy`" features for each release.

To upgrade an existing CLI installation use the appropriate package manager command
(for example `brew upgrade`) or, if you manually installed the CLI, follow the
<<getting-started-manual-cli-installation, standard instructions>> remembering to
update your `PATH` environment variable to remove any older references.



[[getting-started-first-application]]
== Developing your first Spring Boot application
Let's develop a simple "`Hello World!`" web application in Java that highlights some
of Spring Boot's key features. We'll use Maven to build this project since most IDEs
support it.

TIP: The http://spring.io[spring.io] web site contains many "`Getting Started`" guides
that use Spring Boot. If you're looking to solve a specific problem; check there first.

Before we begin, open a terminal to check that you have valid versions of Java and Maven
installed.

[indent=0]
----
	$ java -version
	java version "1.7.0_51"
	Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
	Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)
----

[indent=0]
----
	$ mvn -v
	Apache Maven 3.2.3 (33f8c3e1027c3ddde99d3cdebad2656a31e8fdf4; 2014-08-11T13:58:10-07:00)
	Maven home: /Users/user/tools/apache-maven-3.1.1
	Java version: 1.7.0_51, vendor: Oracle Corporation
----

NOTE: This sample needs to be created in its own folder. Subsequent instructions assume
that you have created a suitable folder and that it is your "`current directory`".



[[getting-started-first-application-pom]]
=== Creating the POM
We need to start by creating a Maven `pom.xml` file. The `pom.xml` is the recipe that
will be used to build your project. Open your favorite text editor and add the following:

[source,xml,indent=0,subs="verbatim,quotes,attributes"]
----
	<?xml version="1.0" encoding="UTF-8"?>
	<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
		xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
		<modelVersion>4.0.0</modelVersion>

		<groupId>com.example</groupId>
		<artifactId>myproject</artifactId>
		<version>0.0.1-SNAPSHOT</version>

		<parent>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-parent</artifactId>
			<version>{spring-boot-version}</version>
		</parent>

		<!-- Additional lines to be added here... -->

ifeval::["{spring-boot-repo}" != "release"]
		<!-- (you don't need this if you are using a .RELEASE version) -->
		<repositories>
			<repository>
				<id>spring-snapshots</id>
				<url>http://repo.spring.io/snapshot</url>
				<snapshots><enabled>true</enabled></snapshots>
			</repository>
			<repository>
				<id>spring-milestones</id>
				<url>http://repo.spring.io/milestone</url>
			</repository>
		</repositories>
		<pluginRepositories>
			<pluginRepository>
				<id>spring-snapshots</id>
				<url>http://repo.spring.io/snapshot</url>
			</pluginRepository>
			<pluginRepository>
				<id>spring-milestones</id>
				<url>http://repo.spring.io/milestone</url>
			</pluginRepository>
		</pluginRepositories>
endif::[]
	</project>
----

This should give you a working build, you can test it out by running `mvn package` (you
can ignore the "`jar will be empty - no content was marked for inclusion!'`" warning for
now).

NOTE: At this point you could import the project into an IDE (most modern Java IDE's
include built-in support for Maven). For simplicity, we will continue to use a plain
text editor for this example.



[[getting-started-first-application-dependencies]]
=== Adding classpath dependencies
Spring Boot provides a number of "`Starter POMs`" that make easy to add jars to your
classpath. Our sample application has already used `spring-boot-starter-parent` in the
`parent` section of the POM. The `spring-boot-starter-parent` is a special starter
that provides useful Maven defaults. It also provides a `dependency-management` section
so that you can omit `version` tags for "`blessed`" dependencies.

Other "`Starter POMs`" simply provide dependencies that you are likely to need when
developing a specific type of application. Since we are developing a web application, we
will add a `spring-boot-starter-web` dependency -- but before that, let's look at what we
currently have.

[indent=0]
----
	$ mvn dependency:tree

	[INFO] com.example:myproject:jar:0.0.1-SNAPSHOT
----

The `mvn dependency:tree` command prints a tree representation of your project dependencies.
You can see that `spring-boot-starter-parent` provides no
dependencies by itself. Let's edit our `pom.xml` and add the `spring-boot-starter-web` dependency
just below the `parent` section:

[source,xml,indent=0,subs="verbatim,quotes,attributes"]
----
	<dependencies>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-web</artifactId>
		</dependency>
	</dependencies>
----

If you run `mvn dependency:tree` again, you will see that there are now a number of
additional dependencies, including the Tomcat web server and Spring Boot itself.



[[getting-started-first-application-code]]
=== Writing the code
To finish our application we need to create a single Java file. Maven will compile sources
from `src/main/java` by default so you need to create that folder structure, then add a
file named `src/main/java/Example.java`:

[source,java,indent=0]
----
	import org.springframework.boot.*;
	import org.springframework.boot.autoconfigure.*;
	import org.springframework.stereotype.*;
	import org.springframework.web.bind.annotation.*;

	@RestController
	@EnableAutoConfiguration
	public class Example {

		@RequestMapping("/")
		String home() {
			return "Hello World!";
		}

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

	}
----

Although there isn't much code here, quite a lot is going on. Let's step through the
important parts.



[[getting-started-first-application-annotations]]
==== The @RestController and @RequestMapping annotations
The first annotation on our `Example` class is `@RestController`. This is known as a
_stereotype_ annotation. It provides hints for people reading the code, and for Spring,
that the class plays a specific role. In this case, our class is a web `@Controller` so
Spring will consider it when handling incoming web requests.

The `@RequestMapping` annotation provides "`routing`" information. It is telling Spring
that any HTTP request with the path "`/`" should be mapped to the `home` method. The
`@RestController` annotation tells Spring to render the resulting string directly
back to the caller.

TIP: The `@RestController` and `@RequestMapping` annotations are Spring MVC annotations
(they are not specific to Spring Boot). See the {spring-reference}#mvc[MVC section] in
the Spring Reference Documentation for more details.



[[getting-started-first-application-auto-configuration]]
==== The @EnableAutoConfiguration annotation
The second class-level annotation is `@EnableAutoConfiguration`. This annotation tells
Spring Boot to "`guess`" how you will want to configure Spring, based on the jar
dependencies that you have added. Since `spring-boot-starter-web` added Tomcat and
Spring MVC, the auto-configuration will assume that you are developing a web application
and setup Spring accordingly.

.Starter POMs and Auto-Configuration
****
Auto-configuration is designed to work well with "`Starter POMs`", but the two concepts
are not directly tied. You are free to pick-and-choose jar dependencies outside of the
starter POMs and Spring Boot will still do its best to auto-configure your application.
****



[[getting-started-first-application-main-method]]
==== The "`main`" method
The final part of our application is the `main` method. This is just a standard method
that follows the Java convention for an application entry point. Our main method delegates
to Spring Boot's `SpringApplication` class by calling `run`. `SpringApplication` will
bootstrap our application, starting Spring which will in turn start the auto-configured
Tomcat web server. We need to pass `Example.class` as an argument to the `run` method to
tell `SpringApplication` which is the primary Spring component. The `args` array is also
passed through to expose any command-line arguments.



[[getting-started-first-application-run]]
=== Running the example
At this point our application should work. Since we have used the
`spring-boot-starter-parent` POM we have a useful `run` goal that we can use to start
the application. Type `mvn spring-boot:run` from the root project directory to start the
application:

[indent=0,subs="attributes"]
----
	$ mvn spring-boot:run

	  .   ____          _            __ _ _
	 /\\ / ___'_ __ _ _(_)_ __  __ _ \ \ \ \
	( ( )\___ | '_ | '_| | '_ \/ _` | \ \ \ \
	 \\/  ___)| |_)| | | | | || (_| |  ) ) ) )
	  '  |____| .__|_| |_|_| |_\__, | / / / /
	 =========|_|==============|___/=/_/_/_/
	 :: Spring Boot ::  (v{spring-boot-version})
	....... . . .
	....... . . . (log output here)
	....... . . .
	........ Started Example in 2.222 seconds (JVM running for 6.514)
----

If you open a web browser to http://localhost:8080 you should see the following output:

[indent=0]
----
	Hello World!
----

To gracefully exit the application hit `ctrl-c`.



[[getting-started-first-application-executable-jar]]
=== Creating an executable jar
Let's finish our example by creating a completely self-contained executable jar file that
we could run in production. Executable jars (sometimes called "`fat jars`") are archives
containing your compiled classes along with all of the jar dependencies that your code
needs to run.

.Executable jars and Java
****
Java does not provide any standard way to load nested jar files (i.e. jar files that are
themselves contained within a jar). This can be problematic if you are looking to
distribute a self-contained application.

To solve this problem, many developers use "`shaded`" jars. A shaded jar simply packages
all classes, from all jars, into a single "`uber jar`". The problem with shaded jars is that
it becomes hard to see which libraries you are actually using in your application. It can
also be problematic if the the same filename is used (but with different content) in
multiple jars.

Spring Boot takes a <<appendix-executable-jar-format.adoc#executable-jar, different
approach>> and allows you to actually nest jars directly.
****

To create an executable jar we need to add the `spring-boot-maven-plugin` to our
`pom.xml`. Insert the following lines just below the `dependencies` section:

[source,xml,indent=0,subs="verbatim,quotes,attributes"]
----
	<build>
		<plugins>
			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
			</plugin>
		</plugins>
	</build>
----

NOTE: The `spring-boot-starter-parent` POM includes `<executions>` configuration to
bind the `repackage` goal. If you are not using the parent POM you will need to declare
this configuration yourself. See the {spring-boot-maven-plugin-site}/usage.html[plugin
documentation] for details.

Save your `pom.xml` and run `mvn package` from the command line:

[indent=0,subs="attributes"]
----
	$ mvn package

	[INFO] Scanning for projects...
	[INFO]
	[INFO] ------------------------------------------------------------------------

	[INFO] ------------------------------------------------------------------------
	[INFO] BUILD SUCCESS
	[INFO] ------------------------------------------------------------------------
----

If you look in the `target` directory you should see `myproject-0.0.1-SNAPSHOT.jar`. The
file should be around 10 Mb in size. If you want to peek inside, you can use `jar tvf`:

[indent=0]
----
	$ jar tvf target/myproject-0.0.1-SNAPSHOT.jar
----

You should also see a much smaller file named `myproject-0.0.1-SNAPSHOT.jar.original`
in the `target` directory. This is the original jar file that Maven created before it was
repackaged by Spring Boot.

To run that application, use the `java -jar` command:

[indent=0,subs="attributes"]
----
	$ java -jar target/myproject-0.0.1-SNAPSHOT.jar

	  .   ____          _            __ _ _
	 /\\ / ___'_ __ _ _(_)_ __  __ _ \ \ \ \
	( ( )\___ | '_ | '_| | '_ \/ _` | \ \ \ \

	  '  |____| .__|_| |_|_| |_\__, | / / / /
	 =========|_|==============|___/=/_/_/_/
	 :: Spring Boot ::  (v{spring-boot-version})
	....... . . .
	....... . . . (log output here)
	....... . . .
	........ Started Example in 2.536 seconds (JVM running for 2.864)

== What to read next
Hopefully this section has provided you with some of the Spring Boot basics, and got you
on your way to writing your own applications. If you're a task-oriented type of
developer you might want to jump over to http://spring.io and check out some of the
http://spring.io/guides/[getting started] guides that solve specific
"`How do I do that with Spring`" problems; we also have Spring Boot-specific
_<<howto.adoc#howto, How-to>>_ reference documentation.

Otherwise, the next logical step is to read _<<using-spring-boot.adoc#using-boot>>_. If
you're really impatient, you could also jump ahead and read about
_<<spring-boot-features.adoc#boot-features, Spring Boot features>>_.
