Chapter 3: Working on RESTful Web Services

In any microservice development, one of the core aspects is how the microservice interfaces with the external world. RESTful or restful has emerged as the golden standard of building these service interfaces. RESTful treats all information exchange as a resource exchange among systems. A resource represents the state of the object at the time of the transfer, hence the term Representational State Transfer (REST). In this chapter, we will explore the key aspects of working on these restful interfaces in the Micronaut framework. We will continue with the controller-service-repository pattern and add restful endpoints to the microservice projects within the pet-clinic application. For outgoing and incoming payloads to these endpoints, we will use data transfer objects (DTOs) in tandem with MapStruct to map DTOs to/from entities. For hands-on work, we will work to add restful endpoints to the following microservices:
