This is a java project to build a stand-alone server which implements the OpenAPI Spec. You can find out more about both the spec and the framework at http://swagger.io.
To run the server, run this task:
mvn clean package mvn tomcat7:run
This will start tomcat embedded on port 9090.
Once started, you can navigate to http://localhost:9090/api/api-doc/swagger.json to view the Swagger Resource Listing. This tells you that the server is up and ready to demonstrate Swagger.
There is an HTML5-based API tool bundled in this sample--you can view it it at http://localhost:9090. This lets you inspect the API using an interactive UI. You can access the source of this code from here
