Helidon SE OpenAPI Example

This example shows a simple greeting application, similar to the one from the Helidon SE QuickStart, enhanced with OpenAPI support.

Most of the OpenAPI document in this example comes from a static file packaged with the application.

Build and run

mvn package
java -jar target/helidon-examples-openapi.jar

Try the endpoints:

curl -X GET http://localhost:8080/greet
{"message":"Hello World!"}

curl -X GET http://localhost:8080/greet/Joe
{"message":"Hello Joe!"}

curl -X PUT -H "Content-Type: application/json" -d '{"greeting" : "Hola"}' http://localhost:8080/greet/greeting

curl -X GET http://localhost:8080/greet/Jose
{"message":"Hola Jose!"}

curl -X GET http://localhost:8080/openapi
[lengthy OpenAPI document]

The output describes not only then endpoints in GreetService as described in the static file but also an endpoint contributed by the SimpleAPIModelReader.
