- @Controller used to mark a class as a web request handler. It’s mostly used with Spring MVC application.
- The @Controller annotation indicates that a particular class serves the role of a controller
- @RestController is a annotation that is combination of the @Controller and @ResponseBody annotations .
- In @RestController, we don’t need to use @ResponseBody on every handler method.
So the following two controller should do the same.
@RestController= @Controller+@ResponseBody.
@Controller
@ResponseBody
public class MyController { }
@RestController
public class MyRestController { }
