Controller中request的疑问

1. springmvc 的Controller 中 注入request 线程安全吗？ 原理是什么？

2. springmvc 的Controller 中如下代码线程安全吗？

@Controller
public class AController{

    protected HttpServletRequest request;
    protected HttpServletResponse response;

    @ModelAttribute
    public void bindRequestObject(HttpServletRequest request, HttpServletResponse response) {
        this.request = request;
        this.response = response;
    }

    @RequestMapping("/test")
    public Result test(){
        System.out.println(request.toString());
    }
}
