Creating a Simple REST Controller

The @RestController annotation marks a class as a web controller where every method returns data directly to the HTTP response body instead of rendering a template.

java
@RestController
public class WelcomeController {
    @GetMapping("/welcome")
    public String welcome() {
        return "Welcome to Spring Boot!";
    }
}
