• Be simple
• No Spring
• In-memory store
• Run as Java standalone app
• Tests

• Gradle
• Git

There is helper script money-service.sh provided for *nix environments to simplify testing. Just use its functions directly on other OS.

git clone https://[email protected]/alex-rnv/money-service.git
cd money-service
./money-service.sh build
./money-service.sh start
./money-service.sh fulfill # adds some test accounts to in-memory store

By default, 8080 port is used. Transfer example:

curl localhost:8080/transfer?from=<id>&to=<id>&amount=<num>

To check account information before and after transfer, use

curl localhost:8080/account/find?id=<id>

• Simplified data model.
• HTTP GET is used with no auth (just easier to check in browser).
• No code comments, as it is standard layered classes hierarchy.
• No unit tests, as business logic is simple and covered by integration test.
