Question

我是Spring的新手我正在尝试运行spring应用程序，我得到的DispatcherServlet类未找到异常。以下是我用过的代码，有人可以帮帮我吗？我尝试了stackoverflow和谷歌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>

index.jsp - WEB-INF

 <html>
    <head>
        <title>rai studies</title>
    </head>
    <body>

            Welcome...
            <a href="hello"><br>Click here to check the output :-)</a>
    </body>
    </html>

Answer 1

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

在上面的行中有拼写错误。它应该是

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