错误信息：找不到带有URI [/TestSpringWebApp/hello.htm]的HTTP请求的映射

任何帮助将不胜感激！

我正在使用批注将请求映射到控制器。控制器代码：

@Controller
@RequestMapping("/hello.htm")
public class HelloController  {    
    protected final Log logger = LogFactory.getLog(getClass());

    public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response)    
            throws ServletException, IOException {
        String now = (new Date()).toString();

        logger.info("Returning hello view with " + now);

        return new ModelAndView("hello", "now", now);    
    }    
}

Dispatcher-servlet.xml如下：

    Most controllers will use the ControllerClassNameHandlerMapping above, but
