Clone this git repo and use sbt run to start the Akka Http server.
Uses swagger-akka-http which is built using swagger.io libs.
Test using http://petstore.swagger.io/ and replace the swagger.json with http://localhost:12345/api-docs/swagger.json
The Swagger UI can be used to send sample requests.
Note that the sample now uses swagger-akka-http 0.11.0 which has some breaking changes.
