Getting started with @EmbeddedKafka and Spring Kafka auto-configuration in a @SpringBootTest made working together despite mismatching defaults by adjusting bootstrapServersProperty

On my serverless journey, I had a closer look at the technologies around. Since I have been implementing applications with Spring for many years, it was natural to try Spring Cloud Function. Let's have a closer look at how a serverless function running as Azure Function can be implemented with Spring.

The idea of an API-first approach is to treat APIs as first-class citizens by building the software product around APIs. Formal specifications serve as the contract and define, what the consumer can expect from the API. To ensure consistency of the contract and the implementation, some parts of the source code can be generated from the specification document.

The hexagonal-like architectures are helping to increase the longevity of software, effectively eliminating the coupling between the coded business knowledge and the technology. In a couple of posts I will share with you mimacom's way of tackling Onion Architecture with Spring Boot. In this first part I will give you more insights about it through a github-hosted example showing a simple implementation of ShoppingList's API's.

To test WebClient code, we need a different setup than for RestTemplate based clients. In WebFlux applications the use of the OkHttp MockWebServer is recommended.
