Creating a REST Controller

In this lesson, we will create a REST service with a request mapping /welcome and send it a request from a REST client (web browser or Postman). The service will respond with a welcome message.

@RestController

First, we will create a controller class called PlayerController with the @RestController annotation. This annotation is an extension of @Controller annotation. The @RestController annotation has support for REST requests and responses and automatically handles the data binding between the Java POJOs and JSON.
