Project

A RESTful API for Bank Account creation and performing different actions of the different types of BankAccount.

CHECKING_ACCOUNT, SAVINGS_ACCOUNT and PRIVATE_LOAN_ACCOUNT

Solution

Since the app is supposed to be stateless, the below design considerations were made:

• Repository methods are synchronized to ensure thread saftey
• Bank accounts are stored in Hashmap with IBAN as key for easy lookup (0(1))

Technologies

This project is created with:

• Java version 11
• SpringBoot version 2.3.5.RELEASE
• RestAssured, Junit 5 and Mockito for Testing
• Docker for containerization
• Swagger for API documentation

Installation and Running

The project can be run in two ways:

• Gradle
• Docker

Maven

To start the app using gradle, you'll need to run the command below:

./gradlew bootRun

Docker

To run the app as a docker container, we have to first package the jar by running the command below

./gradlew build

build the image using the Dockerfile using the command below

 docker build ${project-dir} -t sample-tag

and then run the app in a container by using the command below:

docker run -p 8080:8080 sample-tag

App should be available at localhost:8080

./gradlew clean test

Production ready considerations(out of scope)

• Metrics and Alerts

Side Note :)

• Since application is supposed to be stateless, we cannot get the ACID properties of a relational database to gaurantee TRANSACTIONS
