Java @SameUrlData Annotation: URL Parameter Binding in Spring Framework

The "@SameUrlData" annotation in Java is used in the Spring Framework to indicate that the request data should be populated from the URL parameters. It is typically used in conjunction with the @RequestMapping annotation to bind the URL parameters to method parameters in a controller class.\n\nFor example, consider the following method in a Spring MVC controller:\n\njava\n@RequestMapping(value = "/user/{id}", method = RequestMethod.GET)\npublic String getUser(@SameUrlData @PathVariable int id) {\n // Code to retrieve user with the given id\n // ...\n}\n\n\nIn this example, the @SameUrlData annotation is used before the @PathVariable annotation to indicate that the "id" parameter should be populated from the URL parameter with the same name.\n\nSo, when a GET request is made to "/user/123", the value "123" will be automatically bound to the "id" parameter in the getUser() method.\n\nNote that the @SameUrlData annotation is not a standard Java annotation, but rather a custom annotation provided by the Spring Framework.
