在eclipse下创建一个dynamic project,

然后在WebContent目录下创建lib文件夹，导入所需jar包

注:mysql-connector-java可以不导入。

在web.xml配置如下：

<?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" 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>TalkBox</display-name>


<servlet>
   <servlet-name>springDispatcherServlet</servlet-name>
   <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
   
   <init-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:springmvc.xml</param-value>
   </init-param>

   
   <load-on-startup>0</load-on-startup>
</servlet>

<servlet-mapping>
   <servlet-name>springDispatcherServlet</servlet-name>
   <url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>

在src目录下创建springmvc.xml，内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xmlns:context="http://www.springframework.org/schema/context"
      xmlns:mvc="http://www.springframework.org/schema/mvc"
      xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
          http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
          http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">


         
         <context:component-scan base-package="com.fwk.springmvc"></context:component-scan>

         
         <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
             <property name = "prefix" value="../"></property>
             <property name = "suffix" value = ".jsp"></property>
         </bean>
</beans>

src文件夹下新建com.fwk.springmvc包，包下新建HelloWorld.java：

package com.fwk.springmvc;

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

@Controller
public class HelloWorld {

   @RequestMapping("/helloworld")
   public String Hello(){
       System.out.println("hello world");
       return "success";
   }
}

再在webContent
目录下新建index.jsp:

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<a href="helloworld">hello world</a>
</body>
</html>

以及success.jsp:

然后运行在服务器上即可
