Differences between @Controller and @restcontroller (problems encountered in project learning, annotations added incorrectly cannot jump to JSP)

Article Summary

?? 1.

Official documents:
@RestController is a stereotype annotation that combines @ResponseBody and @Controller.
It means:
@RestController annotations are equivalent to @responsebody + @Controller together.

1) If you use the @restcontroller annotation controller only, the method in the controller cannot return to the JSP page, and the configured view resolver Internalresourceviewresolver does not work. The returned content is the content in return.

For example: should be to the success.jsp page, then its display success.

2) If you need to return to the specified page, you need to use the @Controller with the view resolver internalresourceviewresolver.
3) If you need to return Json,xml or custom mediatype content to the page, you need to add @responsebody annotations to the corresponding method.

1. Controller, the common denominator of restcontroller

is used to indicate whether a class in spring can receive HTTP requests

2. Controller, different points of Restcontroller

@Controller identifies a spring class that is a spring MVC controller processor

@RestController: A convenience annotation that does nothing more than adding the @Controller and @ResponseBody annotations. The @RestController is a combination of @controller and @responsebody, with two annotations combined.

Examples are as follows:

2. @Controller
4. @ResponseBody
6. public class Mycontroller {}
10. @RestController
12. public class Myrestcontroller {}
