Money Transfer API

REST API used to transfer a given amount of money between two accounts (only supports GBP currency).

Summary

Written in Java 8 and Ratpack with:

• Lombok for awesomeness
• Uses JUnit and Ratpack Test for testing
• Uses ConcurrentUnit for concurrency tests via JUnit
• Uses basic in-memory data structures for persistence
• Uses Hibernate validator for JSR-303 validations on requests

Build

If you want to build the application, please run:

mvn clean install

Run tests

If you want to execute the tests, please run:

mvn clean verify

Run app

You can run the app by:

• Running the main class from your IDE
• Building the app via Maven and running the generated uber jar from the target folder.
• Downloading the JAR from the releases page and executing:

java -jar money-transfer-api-1.0-SNAPSHOT.jar

Usage

A swagger.yml file has been provided that can be imported into https://editor.swagger.io, unfortunately Ratpack doesn't offer a nice way of doing this inside the app.

When using the editor, it will call your localhost so make sure the app is started.
