Brief

In this project, a simplified implementation of card and eWallet payment has been developed on IntelliJ by Giorgos Karypidis, Alexander Kyriakou, Dimitris Fountoulis and Alexis Kotsampasis. The eWallet payment functionality was built on an existing source code provided by the Code.Hub team, which assisted us during the whole journey.

Prerequisites for deployment

You'll need certain tools in order to be able to execute the code.

• IntelliJ, or any Java IDE
• Docker
• Postman
• RabbitMQ

The database entries used here are pulled from the implemented H2 server in IntelliJ.

Deployment

1. Run Edge module
2. Run Integration module
3. Run Docker
4. Run Postman
5. Via a browser login to http://localhost:15672 with credentials guest - guest
6. In Postman select Post method with URL http://localhost:8080/api/feeder for Card payments or http://localhost:8080/api/wallet/feeder for eWallet payments. Then you'll need to supply a simple JSON query as follows (copy-paste it in Body tab and fill the gaps):

Card payment:

{
"cid": "CU#########",
"creditorName": "@@@ @@@",
"creditorIBAN": "@@##############",
"debtorName": "@@@ @@@",
"debtorIBAN": "@@##############",
"paymentAmount": "##.#",
"valuerDate": "Year/Month/Day",
"paymentCurrency": "EUR",
"feeAmount": "#",
"feeCurrency": "EUR"
}

eWallet payment:

{
"cid": "CU#########",
"creditorName": "@@@ @@@",
"creditorIBAN": "@@##############",
"debtorName": "@@@ @@@",
"debtorIBAN": "@@##############",
"paymentAmount": "##.#",
"valuerDate": "Year/Month/Day",
"paymentCurrency": "EUR",
}

Once the respective query has been sent, check on RabbitMQ that it has registered in Queues. If the payment can be processed, it'll be shown in the log file payments.

ps: Note that in eWallet payments, no fee amount and fee currency needs to be declared, as they're both calculated by the respective module.

The End!

Thank you Code.Hub, Piraeus Bank and ReGeneration for this amazing learning experience.
