Spring Applications

Project: Shipping Client

The objective of this exercise is to use message queues to process and ship orders asynchronously.

1. Add the starters spring-boot-starter-activemq and spring-boot-starter-json as dependencies to the bookstore application.
2. Add the configuration class JmsConfig to the application to configure the Jackson message converter.
3. Use the shipping DTO classes to implement a component ShippingClient that
   • sends a ShippingOrder message to the OrderQueue after an order has been accepted
   • sends a ShippingCancel message to the CancelQueue if an order has to be canceled
   • receives ShippingInfo messages from the InfoQueue and updates the status of the corresponding order accordingly
4. Inject the shipping client into the OrderService and use it to initiate the shipping of placed orders.
5. Add the library org.apache.activemq:activemq-broker as test dependency and run the OrderServiceIT integration test.
