Spring-retail-website

Task : On a retail website, the following discounts apply:

If the user is an employee of the store, he gets a 30% discount
If the user is an affiliate of the store, he gets a 10% discount
If the user has been a customer for over 2 years, he gets a 5% discount.
For every $100 on the bill, there would be a $ 5 discount (e.g. for $ 990, you get $ 45 as a discount).
The percentage based discounts do not apply on groceries.
A user can get only one of the percentage based discounts on a bill.

Write a Spring Boot Java application with test cases, which exposes an API such that given a bill, it finds the net payable amount.

Requirements

For building and running the application you need:

JDK 1.8

There are several ways to run a Spring Boot application on your local machine. One way is to execute the main method in the com.springboot.retail.SpringRetailWebsiteApplication class from your IDE.

Alternatively you can use the Spring Boot Maven plugin like so:

mvn spring-boot:run

Testing Steps

Once the application is up and running : The SpringBoot can be accessed from localhost:8080 (default port 8080 is used , so please free up the port before running the application)
