Mocked Data in table

Tasks

1. Create REST API for showing products related to input continent

input

GET: localhost:8080/v1/product?continent=asia

response when product(s) found (the type must be the same as example)

[
    {
        "id": "5c65721f-c21b-824f-add3-4539a3be815b",
        "price": 555.123,
        "continent": "asia",
        "multiplier": 4,

        "price": 10,
        "continent": "asia",
        "multiplier": 20,
        "createdAt": "2021-01-06T00:00:00.123"
    },
    {
        "id": "219014d0-e990-c840-8969-85623b2ac9ae",
        "price": 1234,

        "multiplier": 555.555555,
        "createdAt": "2021-01-05T00:00:00.123"
    },
    {
        "id": "084bceb5-ef34-aa47-ad78-d3b5d59e62e2",

        "continent": "asia",
        "multiplier": 4.123456,
        "createdAt": "2021-01-04T00:00:00.123"
    }
]

note: HTTP status 200
note2: createdAt always show 3 digits of milliseconds

response when product not found

[]

note: HTTP status 200

2. Create REST API for adding new product

input (the type must be the same as example)

POST: localhost:8080/v1/product

{
    "price": 123.4567,
    "continent": "new",
    "multiplier": 10
}

response when create successful (the type must be the same as example)

{
    "id": "ed2ae6f0-deba-4007-8e02-f46f4a7e388f",
    "price": 123.4567,
    "continent": "new",
    "multiplier": 10,
    "createdAt": "2021-02-10T18:33:37.394"
}

note: HTTP status 201
note2: createdAt always show 3 digits of milliseconds

3. Modify REST API in (1) and (2) to show more field as below response

1. field name = multipliedValue
2. field value = price * multiplier
3. field decimal = 6 with rounding mode Floor (1.1234567 will be shown as 1.123456, 1.123 will be shown as 1.123000)

input

GET: localhost:8080/v1/product?continent=asia

response when product(s) found (the type must be the same as example)
