spring-mvc Spring-MVC with annotations


In this topic you'll read about annotations mainly related to Spring MVC. Some of the related annotations are as follows: @Controller, @RequestMapping, @RequestParam, @RequestBody, @ResponseBody, @RestController, @ModelAttribute, @ControllerAdvice, @ExceptionHandler, @ResponseStatus.

Of course there're more annotations which are extremly important as well but not belong directly to Spring MVC. Such as: @Required, @Autowired, @Resource, and many more.


@ControllerWith @Controller annotation you mark a Java Class as a Class that holds HTTP handlers, in other words, HTTP access points to your application.
@RequestMappingThe @RequestMapping annotation is the one that you'll use to mark HTTP handlers (HTTP access points to your application) within your @Controller Class
@RequestParamUse the @RequestParam annotation to bind request parameters to a method parameter in your controller.
