Spring Boot Question

Difference between @RestController and @Controller in Spring?

Accepted Answer

1) The @Controller is a common annotation which is used to mark a class as Spring MVC Controller while the @RestController is a special controller used in RESTFul web services and the equivalent of @Controller + @ResponseBody.

2) The @RestController is relatively new, added only on Spring 4.0 but @Controller is an old annotation, exists since Spring started supporting annotation, and officially it was added on Spring 2.5 version.

3) The @Controller annotation indicates that the class is a “Controller” e.g. a web controller while the @RestController annotation indicates that the class is a controller where @RequestMapping methods assume @ResponseBody semantics by default i.e. servicing REST API.

4) The @Controller is a specialization of @Component annotation while @RestController is a specialization of @Controller annotation.
