This is a simple system, used for transferring money between accounts, withdraw and deposit, backed by
- Spark Framework for REST interaction
- JOOQ for DB work
- Google Guava for locking mechanism
- Cactoos for OOP-style programming
- SQLite as simpliest possible DB engine
To run the app from cli you'll need java at least 1.8, maven 3.5.0.
To start server, put this in cli from the project root:
mvn clean package && java -jar target/target/transfer-1.0-jar-with-dependencies.jar
It'll start on localhost:8080.
It creates DB file in folder, from which server was started. Don't miss it.
Concurrent bank imitation with REST endpoints such as
GET /api/account/ - returns all accounts
GET /api/account/:id - returns particular account
POST /api/account/ - creates new account
body: {"name": "String", "balance": int}
POST /api/account/withdraw - withdraws money from account
body: {"account": int, "amount": float}
POST /api/account/deposit - deposits money to account
body: {"account": int, "amount": float}
Uses in-memory SQLite db separated for testing and production purposes.
Floats used widely because there is a problem mapping from FLOAT SQLite type to java double.
Tests are running on top of their own web server and db instance.
To run tests simply put this in console (from project root):
mvn clean test
