== JAR Support and Groovy Support
== JAR Support

The last example showed how Spring Boot lets you wire beans that you may not be aware you
need. It also showed how to turn on convenient management services.

module. The various guides demonstrate this dual support through the
`spring-boot-gradle-plugin` and `spring-boot-maven-plugin`.

On top of that, Spring Boot also has Groovy support, letting you build Spring MVC web
applications with as little as a single file.

Create a new file called `app.groovy` and put the following code in it:

====
[source,java]
----
@RestController
class ThisWillActuallyRun {

@GetMapping("/")
String home() {
return "Hello, World!"
}

}
----
====

NOTE: It does not matter where the file is. You can even fit an application that small
inside a https://twitter.com/rob_winch/status/364871658483351552[single tweet]!

Next, https://docs.spring.io/spring-boot/docs/{spring_boot_version}/reference/htmlsingle/#getting-started-installing-the-cli[install Spring Boot's CLI].

Run the Groovy application by running the following command:

====
[source,bash]
----
$ spring run app.groovy
----
====

NOTE: Shut down the previous application, to avoid a port collision.

From a different terminal window, run the following curl command (shown with its output):

====
[source,bash]
----
$ curl localhost:8080
Hello, World!
----
====

Spring Boot does this by dynamically adding key annotations to your code and using
http://www.groovy-lang.org/Grape[Groovy Grape] to pull down the libraries that are needed
to make the app run.
