# Docs without a home as yet :(
|Feature |Implementation |Notes |
|---|---|---|
|Launch Spring from Java main |SpringApplication | Plenty of convenience methods and customization opportunities |
|Server |Tomcat or Jetty | |
|Logging |Logback, Log4j or JDK | Sensible defaults configurations. |
|Externalized configuration | Properties or YAML | Support for Spring profiles. Bind automatically to @Bean. |
For a quick introduction and to get started quickly with a new
project, carry on reading. For more in depth coverage of the features
of Spring Boot.Strap, go to the [Feature Guide](docs/Features.md).
# Getting Started
You will need Java (6 at least) and a build tool (Maven is what we use
below, but you are more than welcome to use gradle). These can be
downloaded or installed easily in most operating systems. For Ubuntu:
$ sudo apt-get install openjdk-6-jdk maven
<!--FIXME: short instructions for Mac.-->
## A basic project
If you are using Maven create a really simple `pom.xml` with 2 dependencies:
`pom.xml`
```
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>com.mycompany</groupId>
<artifactId>myproject</artifactId>
<version>1.0.0-SNAPSHOT</version>
<packaging>jar</packaging>
<properties>
<start-class>com.mycompany.Application</start-class>
</properties>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-starter-parent</artifactId>
<version>{{project.version}}</version>
</parent>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-starter</artifactId>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-package-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</project>
```
If you like Gradle, that's fine, and you will know what to do with
those dependencies. The one dependency adds Spring Boot.Config auto
configuration and the Tomcat container to your application. If you
prefer Jetty you can just add the embedded Jetty jars to your
classpath instead of Tomcat.
Now write a simple main class
`Application.java`
```
package com.mycompany;
import org.springframework.boot.SpringApplication;
import org.springframework.context.annotation.Configuration;
@Configuration
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
```
You should be able to run it already:
$ mvn package
$ java -jar target/myproject-1.0.0-SNAPSHOT.jar
. ____ _ __ _ _
/\\ / ___'_ __ _ _(_)_ __ __ _ \ \ \ \
( ( )\___ | '_ | '_| | '_ \/ _` | \ \ \ \

Spring Bootstrap
2013-07-19 17:13:51.673 INFO 18937 --- [ main] com.mycompany.Application ...
... <logs showing application starting up>
It doesn't do anything yet, but that's because all we did is start a
Spring `ApplicationContext` and let it close when the JVM stopped.
To make it do something a little bit more interesting you could bind
some command line arguments to the application:
`Application.java`
```
@Configuration
@ConfigurationProperties
@EnableConfigurationProperties
public class Application {
private String message;
@Override
public void run(String... args) throws Exception {
System.err.println(message);
}
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
}
```
The `@ConfigurationProperties` annotation binds the Spring
`Environment` (including command line arguments) to the `Application`
instance, and `CommandLineRunner` is a marker interface for anything
you want to be executed after the content is started. So run it
again and you will see the message:
```
$ mvn package
$ java -jar target/myproject-1.0.0-SNAPSHOT.jar --message="Hello World"
...
Hello World
```
To add more features, add some `@Bean` definitions to your
`Application` class, and read more in the
[Feature Guide](docs/Features.md).

# Spring Boot.Strap
Spring Boot.Strap provides features for the other parts of Spring
Boot. It is relatively unopinionated and therefore usable as a
standalone library for anyone whose tastes diverge from ours.

# Spring Boot
Spring Boot provides the central features for the other modules in the project. It is
relatively unopinionated and it has minimal dependencies which makes it usable as a
stand-alone library for anyone whose tastes diverge from ours.
## SpringApplication
The `SpringApplication` class provides a convenient way to bootstrap a Spring application
that will be started from a `main()` method. In many situations you can just delegate
to the static `SpringApplication.run` method:
```java
public static void main(String[] args) {
SpringApplication.run(SpringConfiguration.class, args);
}
```
$ sudo apt-get install openjdk-6-jdk maven
When you application starts you should see something similar to the following:

Spring Boot (v0.5.0.BUILD-SNAPSHOT)
## A basic project
2013-07-31 00:08:16.117 INFO 56603 --- [ main] o.s.b.s.app.SampleApplication : Starting SampleApplication v0.1.0 on mycomputer with PID 56603 (/apps/myapp.jar started by pwebb)

```
If you are using Maven create a really simple `pom.xml` with 2 dependencies:
By default `INFO` logging messages will shown, including some relevant startup information
such as the user that started the application.
`pom.xml`
### Customizing SpringApplication
If the SpringApplication defaults aren't to your taste you can instead create a local
instance and customize it. For example, to turn off the banner you would write:
```java
public static void main(String[] args) {
SpringApplication app = new SpringApplication(SpringConfiguration.class);
app.setShowBanner(false);
app.run(args);
}
```
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>com.mycompany</groupId>
<artifactId>myproject</artifactId>
<version>1.0.0-SNAPSHOT</version>
<packaging>jar</packaging>
<properties>
<start-class>com.mycompany.Application</start-class>
</properties>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-starter-parent</artifactId>
<version>{{project.version}}</version>
</parent>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-starter</artifactId>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-package-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</project>
```
If you like Gradle, that's fine, and you will know what to do with
those dependencies. The one dependency adds Spring Boot.Config auto
configuration and the Tomcat container to your application. If you
prefer Jetty you can just add the embedded Jetty jars to your
classpath instead of Tomcat.
Now write a simple main class
See the `SpringApplication` Javadoc for a complete list of the configuration options
`Application.java`
```
package com.mycompany;
### Accessing command line properties
By default `SpringApplication` will expose any command line arguments as Spring
Properties. This allows you to easily access arguments using by injecting them
as `@Values`
import org.springframework.boot.SpringApplication;
import org.springframework.context.annotation.Configuration;
```java
import org.springframework.stereotype.*
import org.springframework.beans.factory.annotation.*
@Configuration
public class Application {
@Component
public class MyBean {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
@Value("${name}")
private String name;
// Running 'java -jar myapp.jar --name=Spring' will set this to "Spring"
// ...
}
```
You should be able to run it already:
### CommandLineRunner beans
If you wan't access to the raw command line argument, or you need to run some specific
code once the `SpringApplication` has started you can implement the `CommandLineRunner`
interface. The `run(String... args)` method will be called on all spring beans
implementing the interface.
$ mvn package
$ java -jar target/myproject-1.0.0-SNAPSHOT.jar
```java
import org.springframework.boot.*
import org.springframework.stereotype.*
. ____ _ __ _ _
/\\ / ___'_ __ _ _(_)_ __ __ _ \ \ \ \
( ( )\___ | '_ | '_| | '_ \/ _` | \ \ \ \
\\/ ___)| |_)| | | | | || (_| | ) ) ) )
' |____| .__|_| |_|_| |_\__, | / / / /
=========|_|==============|___/=/_/_/_/
Spring Bootstrap
@Component
public class MyBean implements CommandLineRunner {
2013-07-19 17:13:51.673 INFO 18937 --- [ main] com.mycompany.Application ...
... <logs showing application starting up>
It doesn't do anything yet, but that's because all we did is start a
Spring `ApplicationContext` and let it close when the JVM stopped.
To make it do something a little bit more interesting you could bind
some command line arguments to the application:
public void run(String... args) {
// Do something...
}
`Application.java`
}
```
@Configuration
@ConfigurationProperties
@EnableConfigurationProperties
public class Application {
private String message;
You can additionally implement the `org.springframework.core.Ordered` interface or use
the `org.springframework.core.annotation.Order` annotation if serveral `CommandLineRunner`
beans are defined that must be called in a specific order.
@Override
public void run(String... args) throws Exception {
System.err.println(message);
}
### Application Exit
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
}
```
## Embedded Servlet Container Support
The `@ConfigurationProperties` annotation binds the Spring
`Environment` (including command line arguments) to the `Application`
instance, and `CommandLineRunner` is a marker interface for anything
you want to be executed after the content is started. So run it
again and you will see the message:
## External Configuration
```
$ mvn package
$ java -jar target/myproject-1.0.0-SNAPSHOT.jar --message="Hello World"
...
Hello World
```
## Conditionals
## ApplicationContextInitializers
To add more features, add some `@Bean` definitions to your
`Application` class, and read more in the
[Feature Guide](docs/Features.md).
