The above error, is a low-level error, we all know, add annotations on the Controller @controller and @restcontroller can be on the front of the interface, but the difference is that, When using the former, you must add the annotation @responsebody to the method, and if you do not add @responsebody, the error is reported because the spring default method returns the View Object (page) when using the @controller annotation. With @responsebody, the method returns the specific object. The function of the @RestController is equivalent to the @[email protected] binding body
