直接上图吧：

jar包：

项目目录一览：

这里的HelloWeb-servlet,xml 是在WEB-INF 下

HelloController：

package com.cqu.tutorial;import org.springframework.stereotype.Controller;import org.springframework.ui.ModelMap;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;@Controller@RequestMapping("/hello")public class HelloController {@RequestMapping(method=RequestMethod.GET)public String printHello(ModelMap model){model.addAttribute("message","Hello Spring mvc");return "hello";}}

在WEB-INF 下建立web.xml

<?xml version="1.0" encoding="UTF-8"?><web-app id="WebApp_ID" version="2.4"    xmlns="http://java.sun.com/xml/ns/j2ee"     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee     http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">     <display-name>Spring MVC Application</display-name>     <servlet>      <servlet-name>HelloWeb</servlet-name>      <servlet-class>         org.springframework.web.servlet.DispatcherServlet      </servlet-class>      <load-on-startup>1</load-on-startup>   </servlet>   <servlet-mapping>      <servlet-name>HelloWeb</servlet-name>      <url-pattern>/</url-pattern>   </servlet-mapping></web-app>

这里要注意<url-pattern> 要是"/“ ,之前我用”*.jsp“ 它会提示找不到mapping的路径

然后在同级目录下建立HelloWeb-servlet.xml 这里的HelloWorld 一定要和web里面的servlet-name对应

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"   xmlns:context="http://www.springframework.org/schema/context"   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   xsi:schemaLocation="   http://www.springframework.org/schema/beans        http://www.springframework.org/schema/beans/spring-beans-3.2.xsd   http://www.springframework.org/schema/context    http://www.springframework.org/schema/context/spring-context-3.2.xsd">   <context:component-scan base-package="com.cqu.tutorial"/>   <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">      <property name="prefix" value="/WEB-INF/hello/" />      <property name="suffix" value=".jsp" />   </bean></beans>

最后在WEB-INF 下建一个文件夹 hello ，并且创建hello.jsp文件：

<%@ 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>Hello Spring MVC</title></head><body><h2>${message}</h2></body></html>

然后运行，http://localhost:8080/HelloSpring 这样是不会有东西的，自己添加/hello 就可以了：http://localhost:8080/HelloSpring/hello
