如何连接jsp和控制器

我想用Java和Spring编写一个简单的web应用程序。因此，我已经设置了应用程序，但我有一个问题。这就是

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" 
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
id="WebApp_ID" version="2.5">
  <display-name>SpringMVCApp</display-name>
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  <servlet>
    <servlet-name>springmvcapp</servlet-name>
    <servlet-class>
            org.springframework.web.servlet.DispatcherServlet
        </servlet-class>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>springmvcapp</servlet-name>
    <url-pattern>*.html</url-pattern>
  </servlet-mapping>
</web-app>

现在，当我尝试单击并打开registorZone.jsp时，出现了一个问题

除此之外，我想知道我使用的连接jsp和控制器的方法是否正确

谢谢

这是您告诉调度程序您的spring上下文在哪里的方式：

<servlet>
    <servlet-name>springmvcapp</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>               
            classpath:springmvcapp-servlet.xml
        </param-value>
    </init-param> 
</servlet>

springmvcapp
org.springframework.web.servlet.DispatcherServlet
1.
上下文配置位置
类路径：springmvcapp-servlet.xml

像这样在控制器中添加@RequestMapping

@RequestMapping(value = "/registrazione")
public ModelAndView registrazione(HttpServletRequest request, HttpServletResponse response) throws Exception {
        ModelAndView model = new ModelAndView("registrazione");
        model.addObject("msg", "hello world");
        return model;
    }

我在Controlare的名称上插入了@RequestMapping（“/registrazione”）代码。它是有效的。但我的解决方案是否正确？这取决于url的配置方式。如果它是基本url，则在控制器级别使用它，否则在方法级别使用它。如果有效，请接受它作为答案。

package com.springmvcapp.controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.multiaction.MultiActionController;

@Controller
//@RequestMapping("/RegistrazioneController")
public class RegistrazioneController extends MultiActionController{


    public ModelAndView registrazione(HttpServletRequest request, HttpServletResponse response) throws Exception {
        ModelAndView model = new ModelAndView("registrazione");
        model.addObject("msg", "hello world");
        return model;
    }

    @RequestMapping(value = "/sendDati")
    public String getDataFromForum(@RequestParam String nome){
        System.out.println("pippo");
        return nome;
    }

    public String getViewName() throws Exception {
        return "registrazione";
    }

    public String getPageName() throws Exception {
        return "registrazione";
    }
}

<servlet>
    <servlet-name>springmvcapp</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>               
            classpath:springmvcapp-servlet.xml
        </param-value>
    </init-param> 
</servlet>

@RequestMapping(value = "/registrazione")
public ModelAndView registrazione(HttpServletRequest request, HttpServletResponse response) throws Exception {
        ModelAndView model = new ModelAndView("registrazione");
        model.addObject("msg", "hello world");
        return model;
    }
