Samples of JVM-Microframeworks using MongoDB written in Kotlin

This repo contains several examples of JVM-Microframeworks (e.g. Micronaut, Javalin, http4k, Ktor, Spring Fu, Spark, ...) written in Kotlin accessing a MongoDB.

Scenario

All examples have this scenario in common:

This means they contain a Footballmanager microservice which accesses a MongoDB and provides the data via REST/JSON.

Setup

The MongoDB should be running on mongodb://localhost:27017and have a database footballmanager. Within this database a collection footballer should provide documents of this kind:

{
  "_id" : ObjectId("5cc2d46f8735870692375404"),
  "firstName" : "Manuel",
  "lastName" : "Neuer",
  "position" : "Goalkeeper"
}
{
  "_id" : ObjectId("5cc2d4a08735870692375405"),
  "firstName" : "Antonio",
  "lastName" : "Rüdiger",
  "position" : "Defence"
}
{
  "_id" : ObjectId("5cc2d4c98735870692375406"),
  "firstName" : "Toni",
  "lastName" : "Kroos",
  "position" : "Midfield"
}
{
  "_id" : ObjectId("5cc2d5118735870692375407"),
  "firstName" : "Leroy",
  "lastName" : "Sane",
  "position" : "Striker"
}
