To test it, run it and REST POST any string to localhost:8080
e.g.
curl -H "Content-Type: text/plain" -X POST -d "Created an Order." http://localhost:8080
Then try POST and DELETE to localhost:8080/123
curl -H "Content-Type: text/plain" -X POST -d "Updated an Order." http://localhost:8080/12
curl -H "Content-Type: text/plain" -X DELETE -d "Cancelled an Order." http://localhost:8080/12
