    ModelAndView mv = new ModelAndView("helloworld"); 
    mv.addObject("message", message); 
    mv.addObject("name", name); 
    return mv; 
    }

请确保您的Spring配置文件的名称是'dispatcher-servlet.xml'并放置在'WEB-INF'中。 – Arpit

是的，它被放置在WEB-INF里 – MPPNBD

尝试删除你的xml配置中的 –

终于找到了问题，因为我的Controller java文件没有在目标文件夹中找到，因此dipatcher servlet无法识别控制器映射方法。

感谢您的意见。
