Running the Examples

To follow the simple Spring Boot CLI example:

class GreetingsRestController {

  @RequestMapping("/hi/{name}")
  def hi(@PathVariable String name){
    [ greeting : "Hello, "+name+"!" ]
  }
}

• from the terminal in the same directory as the newly created hi.groovy, run spring jar hi.jar hi.groovy
• you'll be given a .jar that you can execute: java -jar hi.jar
