Hi Sai, Can we try to implement asynchronous communication in this setup by referring to your previous microservices tutorial?

the order-service starts up fine but running the post query on postman gives me a error code 500: "java.net.ConnectException: Connection refused: no further information" i tried changing the ports but still not able to fix the issue

I have the question: If we have four services A, B, C, D in our project and B, C, D services needs to call API of A service. So, we need to define Feign client for service A in B, C, D services and that is duplicate 3 times, right? Is there anyway to define Feign client for A service one time only and it can be shared among 3 services B, C, D?

I think we missed a part here, after placing an order we must subtract the inventory item against that skuCode.

Why is the mysql test container initialized in a static block instead of inside a @BeforeAll method?

I had set the line in my main .properties file. However, when running the tests and configuring them to handle WireMock, it was giving the following error:
{
"type": "about:blank",
"title": "Not Found",
"status": 404,
"detail": "No static resource api/order.",
"instance": "/api/order"
}

java.lang.AssertionError: 1 expectation failed.
Expected status code <201> but was <404>.

I removed the line from the properties file and added i was using just /order. to the controller, and it worked. Do you know why? Since there isn't much difference.
