DTU-Payment-Service

Project Structure

The DTU-Payment-Service consists of 7 projects.

1. The end-to-end tests.
2. A Token Management microservice in token-management-service responsible for managing, consuming and issuing tokens.
3. An Account Management microservice in account-management-service microservice that is responsible for accounts management in DTU Pay.
4. A Payment Management microservice in payment-management-service that is responsible for the communication with the SOAP-based bank service.
5. A Report Management microservice in reporting-service that is responsible for reporting services for customers, merchants and managers.
6. A facade microservice in dtupay-facade that offers an external REST interface. Also, this service communicates through message queues.
7. A message utilities in messaging-utilities provided by Hubert Baumeister.

Dockerization

In our docker-compose files, we run the rabbitMq container first and we have set up custom healthcheck on which the other services depend to make sure it's ready to accept communication with the other services.

Also, we use the eclipse image eclipse-temurin:23-alpine as a base in our service DockerFiles in order to optimize the size of the images.

Prerequisites

Before proceeding to the installation of the project, make sure you have the following technologies installed:

1. Docker
2. Java 23
3. An IDE, such as IntelliJ, or Eclipse

Installation Guide

1. Clone the repository: git clone https://github.com/Zedrichu/DTU-Payment-Service.git
2. Navigate to the end-to-end-test foldercd DTU-Payment-Service/end-to-end-test
3. To build and install the system locally using docker, execute the following script:sh ./build_deploy_test.sh
   The script builds and deploys the docker images, run the tests and then stops the images.
   

Alternatively, in the root folder of the repository the script sh ./build_run.sh is supposed to achieve the same functionality. In case you want to keep the docker images running after build, instead of running the ./build_deploy_test.sh from ./end-to-end-test directory, run the ./build_deploy.sh script.

Note: RabbitMQ Compose Service

Even though the docker-compose mechanism employs a custom health check for the RabbitMQ container, its booting is completely failing occasionally (as seen in our Jenkins build history). To verify the application testing and deployment, one should try restarting the compose deployment until the RabbitMQ service is marked as healthy.
