目录结构

控制类

package com.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class Mycontroller {

    @RequestMapping("/")
    public String index(){
        return "index";
    }
}

###Tomcat

访问404

原因是什么，如何解决呀？

第一 ：首先你的访问为什么访问Student? 你在Mycontroller 中 @RequestMapping("/") 改为 @RequestMapping("/Student")
第二： 你web.xml 没有配置Spring启动的文件和监听器呀
