quarkus-anti-fraud-system

This project uses Quarkus, the Supersonic Subatomic Java Framework.

This is a learning project I built for the JetBrains Academy 'Java Backend Developer' course. It was initially developed with Spring Boot and has now become my first Quarkus application. The 'transfer' took just a few hours using Spring extensions within Quarkus (specifically Spring Web, Spring DI and Spring Data JPA). The project is deployed through Docker using the native image produced with GraalVM . The 'original' project is built with Spring Boot and available here: https://github.com/stiebo/Anti-Fraud-System

Project description: Frauds carry significant financial costs and risks for all stakeholders. So, the presence of an anti-fraud system is a necessity for any serious e-commerce platform.

The Anti-Fraud System project provides a comprehensive framework for detecting and preventing fraudulent financial transactions. By integrating role-based access control, RESTful APIs, heuristic validation rules, and adaptive feedback mechanisms, the system offers a robust solution for financial institutions to safeguard against fraud.

Running the application in dev mode

You can run the application in dev mode that enables live coding using:

./mvnw compile quarkus:dev

NOTE: Quarkus now ships with a Dev UI, which is available in dev mode only at http://localhost:8080/q/dev/.

Packaging and running the application

The application can be packaged using:

./mvnw clean package

It produces the quarkus-run.jar file in the target/quarkus-app/ directory. Be aware that it’s not an über-jar as the dependencies are copied into the target/quarkus-app/lib/ directory.

The application is now runnable using java -jar target/quarkus-app/quarkus-run.jar.

If you want to build an über-jar, execute the following command:

./mvnw package -Dquarkus.package.jar.type=uber-jar

The application, packaged as an über-jar, is now runnable using java -jar target/*-runner.jar.

Creating a native executable

You can create a native executable using:

./mvnw package -Dnative

Or, if you don't have GraalVM installed, you can run the native executable build in a container using:

./mvnw package -Dnative -Dquarkus.native.container-build=true

You can then execute your native executable with: ./target/quarkus-anti-fraud-system-0.0.1-SNAPSHOT-runner

If you want to learn more about building native executables, please consult https://quarkus.io/guides/maven-tooling.
