无法映射到http请求

Question

我的调度程序servlet中有以下声明，当我试图致电http://localhost:9005/Appname/hello/hello.jsp时，它正在说

＆＃34;警告：在DispatcherServlet中找不到带有URI [/EtiwapproSp/WEB-INF/jsp/hello.jsp]的HTTP请求的映射，其名称为＆＃39; dispatcher＆＃39; ＆＃34;并且正在显示404。请帮忙

尽管WEB-INF / jsp / hello.jsp

中有hello.jsp

我的控制器

  @Controller
@RequestMapping("/hello")
public class RequestController {

@RequestMapping(value = "/hello", method = RequestMethod.GET)
  public String printHello(ModelMap model) {
  model.addAttribute("message", "Hello Spring MVC Framework!");
  return "hello";
  }
}
