spring3mvc

一、下载spring压缩包

官网 http://www.springsource.org/download/community

spring-framework-3.2.2-dist.zip(sha1)47.8 MB

spring-framework-3.2.2-dist\spring-framework-3.2.2\libs下有需要的jar包

还需要相关依赖包：spring-framework-3.0.2.RELEASE-dependencies.zip

注意官网上3.0.3版本以后同版本依赖包不提供下载

引入libs目录下除了下面2个其余所有包
spring-struts-3.2.2.jar
spring-webmvc-portlet-3.2.2.jar
引入依赖包下commons.logging-1.1.1.jar及aopalliance-1.0.0.jar

二、配置xml

  1、web.xml配置

<?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_3_0.xsd"  
    id="WebApp_ID"   
    version="3.0">  

    <context-param>  
        <param-name>contextConfigLocation</param-name>  
        <!-- 应用上下文配置文件 -->  
        <param-value>/WEB-INF/spring-servlet.xml</param-value>  
    </context-param>  

    <listener>  
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  
    </listener>  

    <!-- 配置spring核心servlet -->  
    <servlet>  
        <servlet-name>spring</servlet-name>  
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  
        <load-on-startup>1</load-on-startup>  
    </servlet>  
    <!-- url-pattern配置为/，不带文件后缀，会造成其它静态文件(js，css等)不能访问。如配为*.do，则不影响静态文件的访问 -->  
    <servlet-mapping>  
        <servlet-name>spring</servlet-name>  
        <url-pattern>/</url-pattern>  
    </servlet-mapping>  
</web-app> 

2、配置应用上下文 spring-servlet.xml 即配置用于开启基于注解的springMVC功能

<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">  
     <!-- 启动注解驱动的Spring MVC功能，注册请求url和注解POJO类方法的映射-->  
     <mvc:annotation-driven />  

     <!-- 启动包扫描功能，以便注册带有@Controller、@Service、@repository、@Component等注解的类成为spring的bean -->  
     <context:component-scan base-package="cn.ac.ihep.mvc" />  

     <!-- 对模型视图名称的解析，在请求时模型视图名称添加前后缀 -->  
     <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/view/" p:suffix=".jsp" />  
</beans>   

三、开发

1、根据spring-servlet.xml配置的包路径（cn.ac.ihep.mvc）新建控制器Constroller

package cn.ac.ihep.mvc;  
import javax.servlet.http.HttpServletRequest;  
import javax.servlet.http.HttpServletResponse;  
import org.springframework.stereotype.Controller;  
import org.springframework.ui.ModelMap;  
import org.springframework.web.bind.annotation.PathVariable;  
import org.springframework.web.bind.annotation.RequestMapping;  
import org.springframework.web.bind.annotation.RequestMethod;  
import org.springframework.web.servlet.ModelAndView;  
@Controller  
public class RestConstroller {  
    public RestConstroller() {}  
    @RequestMapping(value = "/login/{user}", method = RequestMethod.GET)  
    public ModelAndView myMethod(HttpServletRequest request,
                                 HttpServletResponse response,   
                                 @PathVariable("user") String user, 
                                 ModelMap modelMap) throws Exception {  
        modelMap.put("loginUser", user);  
        return new ModelAndView("/login/hello", modelMap);  
    }  
    @RequestMapping(value = "/welcome", method = RequestMethod.GET)  
    public String registPost() {  
        return "/welcome";  
    }  
}  

2、建jsp视图

视图路径在spring-servlet.xml配置（/WEB-INF/view/），据上述RestConstroller 类，我们在WEB-INF下建立view目录，在view下建立welcome.jsp及login/hello.jsp
welcome.jsp随意，hello.jsp代码如下：

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>  
<%  
String path = request.getContextPath();  
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";  
%>  
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">  
<html>  
<head>  
<base href="<%=basePath%>">  
<title>mvc测试页</title>  
<meta http-equiv="pragma" content="no-cache">  
<meta http-equiv="cache-control" content="no-cache">  
</head>  
<body>  
    你好:<%=request.getAttribute("loginUser") %>，现在时间是<%= new Date() %>  
</body>  
</html>  

3、部署访问
http://localhost:8080/my1s3/welcome  进入 welcome.jsp

http://localhost:8080/my1s3/login/user1 进入 hello.jsp
