Helidon DB Client mongoDB Example

This example shows how to run Helidon DB over mongoDB.

Build

mvn package

This example requires a mongoDB database, start it using docker:

docker run --rm --name mongo -p 27017:27017 mongo

Then run the application:

java -jar target/helidon-examples-dbclient-mongodb.jar

## Exercise

The application has the following endpoints:

http://localhost:8079/db - the main business endpoint (see curl commands below)
http://localhost:8079/metrics - the metrics endpoint (query adds application metrics)
http://localhost:8079/health - has a custom database health check

Application also connects to zipkin on default address. The query operation adds database trace.

curl commands:

curl http://localhost:8079/db - list all Pokemon in the database
curl -i -X PUT -d '{"name":"Squirtle","type":"water"}' http://localhost:8079/db - add a new pokemon
curl http://localhost:8079/db/Squirtle - get a single pokemon
curl -i -X DELETE http://localhost:8079/db/Squirtle - delete a single pokemon
curl -i -X DELETE http://localhost:8079/db - delete all pokemon

The application also supports update and delete - see PokemonService.java for bound endpoints.
