Application

Customer Controller • Will persist new customers • Will query all orders of the customer ( Paging sounds really nice ) • Book Controller • Will persist new book • Will update book’s stock • Order Controller • Will persist new order (statuses may used) • Will update stock records. (Hint: what if it happens if 2 or more users tries to buy one last book at the same time) • Will query order by Id • List orders by date interval ( startDate - endDate ) • Statistics Controller • Will serve customer’s monthly order statistics • Total Order count • Total amount of all purchased orders • Total count of purchased books That endpoint will supply data for the following ui component

we will only consider:

Registering New Customer • Placing a new order • Tracking the stock of books • List all orders of the customer • Viewing the order details • Query Monthly Statistics

In order to run this application, Docker should be build with 'docker-compose build' and then run with 'docker-compose up' commands. (In case of any errors maven clean install can be executed)

Before starting to try the end points, token should be generated and added as a Header in the Postman requests. Postman requests are prepared and placed in 'resources' folder (https://github.com/ahmetyasinu/DemoGetir/blob/master/getir.postman_collection.json).
