RestService with Springboot and Groovy

To test this you have to install GVM follow the instruction for your environment, I use Cygwin and GVM, when you have GVM up and running, install Springboot on GVM:

gvm install springboot

       
//Place this groovy-file in /cygwin/home/your_username
//To kick on the service open cygwin or another terminal and write: 

//spring run your_file_name.groovy
//Now the service is started, open a browser and test the service, f.e: http://localhost:8080/greeting/John
