Implementation of the RESTful API for money transfers between accounts.

The money transfer service represents a server-side application. The separation in layouts lies in basis of the architecture. There are two data packages (me.volart.dao.model and me.volart.dto), it was made intentionally in order to show that we separate client interaction stuff and server things.

The system works with clients who have account with specified currency and amount. The amount is Java long type. Suppose that the fractional parts of currency is included into the long value. The currency is a currency code satisfying the ISO 4217.

For more information regarding currency look at ISO 4217

The system has ability to create, get, delete a client and transfer money between clients.

{clientId} - the long value

To build the service you should run the command below mvn clean package

To run locally from the project folder Cope dependencies to the directory mvn install dependency:copy-dependencies

Then run java -cp target/money-transfer-service-1.0-SNAPSHOT.jar:target/dependency/* me.volart.App

If you want to stop running service press Control+C

To pass tests mvn test

In the me.volart.MoneyTransferServiceIT class there are integration tests.
