Working example of load balancing using spring cloud and ribbon. Modified as per my need. Heavily borrowed from official spring documentation.

Run the user module separately first. It runs on port 8888. Run the hi-user module next. If using IntelliJ, make sure to click "Run in Parallel" so that other instances of same server can be run on different ports.

From within IDE:
spring-boot:run for default 8090 port. 
OR
Set vm option as -Dserver.port=9092/9999. Then enter
spring-boot:run as Command-Line option.
From terminal:
mvn spring-boot:run
OR
SERVER_PORT=9999 mvn spring-boot:run

Test if up:

http://localhost:8888
http://localhost:8090 or 9020 or 9999

See in action:

http://localhost:8888/hi?name=robinhood

Modify the above name parameter again and again to see different greetings.
