1."File-->New-->WebProject"新建一个web项目，命名为springMvc
2.将所需要用到的jar包复制到WEB-INF/lib路径下，然后右键项目，Build Path-->Configure Build Path,在Libraries选项卡中选择Add JARs，选中springMvc项目中WebContent/WEB-INF/lib下的jar包。
3.在WebContent根目录下新建MyJsp.jsp文件，code as:
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<!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>
欢迎大家收看我的视频!提高班 李守宏
<br/>
<h>传递数据</h>
<div>
<c:forEach items="${map}" var="m">
${m.key} -----> ${m.value}<br/>
</c:forEach>
</div>
</body>
</html>
4.WebContent/WEB-INF下创建web.xml文件，代码如下：
<?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" 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>springMVC1</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>springMVC</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:config/spring-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springMVC</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
5.src目录下创建com.tgb.web.controller包，
有MyController.java，代码如下：
package com.tgb.web.controller;
import java.lang.annotation.Annotation;
import java.util.HashMap;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;
public class MyController implements Controller {
@Override
public ModelAndView handleRequest(HttpServletRequest arg0,
HttpServletResponse arg1) throws Exception {
// TODO Auto-generated method stub
Map<String,Object> map=new HashMap<String,Object>();
map.put("121544123", "詹晓玲");
map.put("121544101", "DONG ");
//model.addAttribute("map",map);
//return "/MyJsp";
return new ModelAndView("/MyJsp","map",map);
}
}
有MyControllerAnnotation.java,代码如下：
package com.tgb.web.controller;
import java.util.HashMap;
import java.util.Map;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class MyControllerAnnotation {
@RequestMapping("/annotation")
public String hi(Model model){
Map<String,Object> map=new HashMap<String,Object>();
map.put("121544123", "詹晓玲");
map.put("121544101", "DONG ");
model.addAttribute("map",map);
return "/MyJsp";
}
}
6.在src目录下新建config包，新建spring-servlet.xml文件，代码如下：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:mvc="http://www.springframework.org/schema/mvc"
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-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
<mvc:annotation-driven />
<context:component-scan base-package="com.tgb.web.controller" />
<bean id="urlMapping"
class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<props>
<prop key="/hello">HelloAction </prop> <!-- 映射URL访问 -->
</props>
</property>
</bean>
<bean name="HelloAction" class="com.tgb.web.controller.MyController" />
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
</beans>
项目结构如下图所示：
