Kotlin Service Approaches

Different ways to do server-side services in Kotlin

Examples cover Spring Boot, Ktor and JAX-RS

API

Each example provides the same API

GET http://localhost:8080/greeting returns a 405 with a message

GET http://localhost:8080/greeting/{name}

{
  "name": "{name}",
  "message": "Hello"
}

POST http://localhost:8080/greeting with body

{
  "name": "Name",
  "message": "Bonjour"
}

Changes the greeting message to 'Bonjour', the name is ignored.

Build & Run
