Difference between @Controller and @RestController annotation in Spring MVC.

@Controller denotes that the marked class is a Spring MVC Controller.

@RestController is nothing but a combination of @Controller and @ResponseBody annotations. @RestController annotation marks any class as @Controller and in addition to that it annotates the class with the @ResponseBody annotation.

The following controller definitions are functionally equal.

@Controller
@ResponseBody
public class MVCController { }

@RestController
public class MVCController { }
