mvpjava/java-driver-api-mongo4 repository overview

Demo/tutorial showing how to connect to mongo db 4.0 with Java Driver API.

The Java Application connects to an already running Mongo DB instance on port 27017 on the "admin" database using root user credentials used by looking at environmental variables "MONGO_INITDB_ROOT_USERNAME" and "MONGO_INITDB_ROOT_PASSWORD"

Once connected, the application will enter a loop in which it will insert a new Document into the "metrics" collection every 5 secods. The document consists of a randomly generated domain name (random string) along with a random hit/visit count.

Its compiled as an uber jar (contains all dependancies) needed in order to be run via the "java -jar demo-jar-with-dependencies.jar" command.

This demo is actually part of a larger demo which show cases deploying the jar into a Docker swarm environment in orer to showcase the benifits of using swarm as a developer.
