1.在web.xml中启用springmvc

<?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_3_0.xsd" id="WebApp_ID" version="3.0">  <display-name>SpringMVC</display-name>  <welcome-file-list>    <welcome-file>index.html</welcome-file>    <welcome-file>index.htm</welcome-file>    <welcome-file>index.jsp</welcome-file>    <welcome-file>default.html</welcome-file>    <welcome-file>default.htm</welcome-file>    <welcome-file>default.jsp</welcome-file>  </welcome-file-list><servlet><servlet-name>hello</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>hello</servlet-name><url-pattern>/</url-pattern></servlet-mapping>  <!--处理中文字符编码集-->  <filter>  <filter-name>CharacterFilter</filter-name>  <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>  <init-param>  <param-name>encoding</param-name>  <param-value>UTF-8</param-value>  </init-param>  </filter>  <filter-mapping>  <filter-name>CharacterFilter</filter-name><url-pattern>/*</url-pattern>  </filter-mapping>  </web-app>

2.根据第一步定义的servlet的名字，在web-inf目录下创建一个

<?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/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsdhttp://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd"><!-- 启用对第五步创建的package的注解扫描 --><context:component-scan base-package="org.xk.spring.controller"/><mvc:annotation-driven/><!-- 启用注解模式的springmvc --><!-- SpringMVC查找jsp文件 --><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="viewClass" value="org.springframework.web.servlet.view.JstlView"></property><property name="prefix" value="/WEB-INF/jsp/"></property><property name="suffix" value=".jsp"></property></bean></beans>

3.springmvc的controller,新建一个package(org.dmj.spring.controller)

package org.xk.spring.controller;import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.RequestMapping;@Controllerpublic class HelloController {@RequestMapping({"/hello", "/world"})public String hello(String name, Model model){System.out.println("-> " + name);model.addAttribute("getName" , "你刚才输入的用户姓名：" + name);return "hello";}}

访问地址：http://localhost:8080/SpringMVC/hello?name=test,可以跳转到WEB-INF下的JSP文件夹下的hello.jsp页面。并且${getName }可以获取Controller中的name。
