We have now built our first few microservices using Spring Boot. After being introduced to the microservice landscape, which we will use throughout this book, we learned how to use Spring Initializr to create skeleton projects for each microservice.
Next, we learned how to add APIs using Spring WebFlux for the three core services and implemented a composite service that uses the three core services APIs to create an aggregated view of the information in them. The composite service uses the RestTemplate class in Spring Framework to perform HTTP requests to APIs that are exposed by the core services. After adding logic for error handling in the services, we ran some manual tests on the microservice landscape.
We wrapped this chapter up by learning how to add tests for microservices in isolation and when they work together as a system landscape. To provide controlled...
