In game ads

This is server-side app for renting advert space inside game world.
This application is an intermediary between video game owners and advertisers that are willing to pay for placing their advertisements inside the game world.
Payment is fully covered in this app, I used PayPay for it.
The entire system is a complete and working prototype with basic flow implemented and it is ready for new features development.\

Technology used, some keywords:

Java 8
Spring Boot
Microservice architecture
Spring Cloud Config server - for remote configuration deployment
Spring Netflix-Eureka - for microservices discovery
In-game advertising
Used SQL database for user related data
Remote mongoDB database for statistics data (adverts views number)
Remote image hosting - Cloudinary.

Architecture

Here's architecture picture.

User Interface

UI was rendered with thmyeleaf.
For CSS I used Google Materialize (materializecss.com) just because I didn't know it and I wanted to learn it.\
Here's how home page looks like:
Game page
Here advert provider can choose start and end day of advertising campaign, upload advert image and know how much it will cost him. He also can see stats of this game.
Offer page
Once advert provider completed order, game developer needs to approve (or reject) it.
Payment
Here's how payment works. Part of money goes to In-game-ads owner, part to PayPay and the rest to game developer. Numbers are configurable.

When game developer accepts the offer - advert provider is notified about this and he can pay in advance for the advert campaign.

Client app

Example client game can be found here: https://github.com/Pastew/ingameads-client

Why did I create this app?

The only purpose of creating this app was to learn how Spring Boot works, I don't plan to use it commercially. I also used it as my master's thesis.
