@getMapping and @postmapping, @RestController difference

Differences between @RequestMapping and @GetMapping @PostMapping

@GetMapping is a combination annotation, an abbreviation for @requestmapping (method = Requestmethod.get).

@PostMapping is a combination annotation, an abbreviation for @requestmapping (method = Requestmethod.post).

What is the difference between @Controller and @restcontroller?

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
