Question

我确实经历过一些解决方案，没有一个能够解决我的问题。我一直在找＆＃34; Not Found＆＃34;运行这个简单的spring mvc示例时浏览器出错。我是Spring框架的新手。任何帮助都将受到高度赞赏。

以下是我在运行程序时在控制台上遇到的错误：

WARN [org.springframework.web.servlet.PageNotFound]（默认任务-4）在DispatcherServlet中找不到带有URI [/ Demo1 /]的HTTP请求的映射，名称为＆＃39; SpringDispatcher＆＃39; WARN [org.springframework.web.servlet.PageNotFound]（默认任务-5）在DispatcherServlet中找不到带有URI [/ Demo1 / HelloPage]的HTTP请求的映射，名称为＆＃39; SpringDispatcher＆＃39;

这是web.xml

import java.io.IOException;

import javax.servlet.http.HttpServletResponse;

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

@Controller
public class HomeController {

    @RequestMapping(value="/welcome.html")
    public ModelAndView test(HttpServletResponse response) throws IOException{
        // TODO Auto-generated method stub
        ModelAndView mav = new ModelAndView("HelloPage","msg","Welcome To Spring");


        return mav;

    }
}

HomePage.jsp

<html>
<body>
    <h1>First Spring Example with Deployment Descriptor</h1>

    <h2>${msg}</h2>

</body>
</html>

以下是我的目录结构的样子：

您的jsp名为HomePage.jsp，但您在ModelAndView中返回HelloPage。这些名称需要匹配。（尽管在ModelAndView中不需要.jsp扩展名）
