Is it possible use @Service/@Component instead of @Controller annotation in Spring MVC ( I checked this out and it doesn't work) but why?

CodePudding user response：

The @Controller annotation is a specific type that, like all spring annotations, is derived from the @Component annotation. Note that, depending on use case, it may work, and it may not. Controller classes are often used for mapping server requests to responses.

You can view this Geeks for Geeks article for more info on when to use the @Controller annotation. If you have @RequestMapping annotations in your class, you will not get the same behavior with a Component as you will with Controller.
