@RestController
class HelloWorld {
@RequestMapping("/")
String home() {

4. Invoke in a browser and you have your "Hello World" or just use "curl" as follows
pas@192-168-1-4:~/ibm/software/spring/spring-boot/groovy-example$ curl http://localhost:8080
Hello World!
5. Finally lets create a runnable JAR we can then deploy to IBM Bluemix
pas@192-168-1-4:~/ibm/software/spring/spring-boot/groovy-example$ spring jar hello.jar hello.groovy
6. Finally deploy to IBM Bluemix using the runnable JAR file as follows
pas@192-168-1-4:~/ibm/software/spring/spring-boot/groovy-example$ cf push hello-spring-boot -i 1 -m 256M -p ./hello.jar
