我是spring新手，我正在尝试运行spring应用程序，我得到了DispatcherServlet类not found异常。下面是我使用的代码，有人能帮我吗？我尝试了stackoverflow和google提供的许多解决方案，但我没有得到这个问题的答案。提前谢谢

package com.raistudies.actions;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class HelloWorldAction {

    @RequestMapping(value = "/hello", method = RequestMethod.GET)
    public ModelAndView sayHello(Model model) {
        System.out.println(" hellow world ");
        ModelAndView mav = new ModelAndView();
        mav.setViewName("hello");
        model.addAttribute("helloMessage",
                "Hello World from my spring 3 mvc application");
        return mav;
    }
}

hello.jsp-WEB-INF/jsp/

<html>
    <head>
        <title>Hello world with spring 3 mvc </title>
    </head>
    <body>
        <h1>Welcome! Spring MVC is working well.</h1><br />
        ${helloMessage}
    </body>
</html>

org.springfrmaework.web.servlet.DispatcherServlet

上面一行有拼写错误。应该是

<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

org.springframework.web.servlet.DispatcherServlet

如果找不到DispatcherServlet，我将开始检查类路径依赖关系，并验证它是否确实包含在您的项目中。您好，谢谢您的回复，我在lib目录中有spring web mvc jar文件。非常感谢，问题已经解决，我可以运行该应用程序。再次感谢您的及时帮助。我也检查了拼写，但我没有把注意力集中到DispatcherServlet字符串上。
