Spring Application Services

Project: Shipping Service

1. Implement a Spring Boot application with a shipping service that
• receives messages from the ShippingOrderQueue and processes the shipping orders by waiting a fixed time interval
• receives messages from the ShippingCancelQueue and cancels the shipping if the order has not yet been shipped
• sends messages to the ShippingInfoQueue whenever the status of an order changes
• sends email notifications to the customers after their order has been shipped
2. Implement integration tests to verify the functionality of the service.
