Usage

java -jar payment-tracker-spring-0.0.1-SNAPSHOT.jar 

This command starts Spring Boot application at http://localhost:8080

• To see all records, open browser to show URL http://localhost:8080/payment/stream. Records are represented in form of json stream and updated every second.
• In order to create or modify records, send POST request to http://localhost:8080/payment in form of simple json map. You can create or modify multiple records at once.

Example of getting records in browser after 5 seconds (five times updated):

{"USD":3000}
{"HIT":-2900,"USD":3000}
{"HIT":-2900,"USD":3000,"HIP":1}
{"HIT":-2900,"HAP":2,"USD":3000,"HIP":1}

POST localhost:8080/payment

# Body:
{"HOP":3, "KOP": 5,"MOP": 5}
