Hands-On Microservices with Spring Boot and Spring Cloud

Non-blocking REST APIs in the composite services

To make our REST API in the composite service non-blocking, we need to do the following:

• Change the APIs so that they only return reactive datatypes
• Change the integration layer so it uses a non-blocking HTTP client
• Change the service implementation so it calls the core services APIs in parallel and non-blocking
• Change our tests so that they can test the reactive service
