A fictional client has an existing Micro Service to fetch order and product information. This simple code contains a Search REST API to display a list of potential matches.

The following areas were addressed: Configuration, Architecture, Logic, Exception Handling, Logs, Spring, Persistence, REST, Tests, Documentation, and JAVA.

I've been using spring-boot to make the server up, runnable and ready to receive HTTP requests. The server is started on port 8088.

Besides the Micro Service to fetch order and product information, I've also added a new generic Search REST API to retrieve all relevant information matching the following criteria:

• This search criteria is applied on the status column of the orders table.
• The value of the status should be SHIPPED.

• This search criteria is applied on the discount column of the orders table.

 eg:
 {
         "orderNumber": "RTL_1003",
         "discount": 19.99,
         "taxPercent": 8.5,
         "total": 139.97,
         "totalTax": 11.89,
         "grandTotal": 131.87,
         "status": "SHIPPED",
         "products": [
             {
                 "upc": "1358743283",
                 "sku": "7394650110003",
                 "description": "Polo Shirt",
                 "price": 19.99
             },
             {
                 "upc": "1458843283",
                 "sku": "7394750120000",
                 "description": "Floral Swing Skirt",
                 "price": 69.99
             },
             {
                 "upc": "1258793283",
                 "sku": "7394950140000",
                 "description": "True Skinny Jeans",
                 "price": 49.99
             }
         ]
     }

• This search criteria is applied on the price column of the products table.

• I've added unit tests for all the existing classes in the workspace.

• I've added Spring Integration Tests for all the API endpoints.

1. List Orders: [GET] http://localhost:8088/orders

2. Fetch Order Details: [GET] http://localhost:8088/orders/{order_id}

3. List Products: [GET] http://localhost:8088/products

4. Fetch Product Details: [GET] http://localhost:8088/products/{product_id}
