In the microservice-based architecture, it is a common practice to expose application functionality in terms of RESTful APIs. These APIs can then be accessed via a range of application devices, such as desktop applications, mobile devices, as well as other APIs.
In this chapter, we’ll introduce you to designing and building RESTful APIs with Spring Boot. You’ll also learn to document the API, so the API consumers can find required details about the API, such as the request, response structures, HTTP return codes, etc. Finally, you’ll learn to develop unit test cases to test the API. Lastly, we’ll show you how to secure your RESTful API. Let’s get started.
