**在前两篇的ssh（spring4.2+struts2.3.29+hibernate4.2）博客（[ssh（上）][ssh]，[ssh（下）][ssh 1]）的基础上做一个小小的改动，把struts替换成springmvc。源码在[github][]上。**

**\[springmvc的视频是在网上找后下在手机里，这学期上毛概课时看的![大笑][laugh.gif]\]**

1.给jar包减肥，即去掉struts2.3.29的jar包,把struts开头的jar删除即可。

jar包下载地址：[http://download.csdn.net/detail/change\_on/9565150][http_download.csdn.net_detail_change_on_9565150]

2.具体的项目架构就不展示，都是在前两篇的博客的基础上，基本不改动，就把struts2部分换成springmvc

具体的改动如下：

3.web.xml:把struts2的过滤器去掉，添加springmvc的中央处理器：

<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemalocation="http://java.sun.com/xml/ns/javaee   
        http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">  
      <display-name></display-name>   
         
        
      <context-param>  
        <param-name>contextConfigLocation</param-name>  
        <param-value>classpath:applicationContext.xml</param-value>  
      </context-param>  
         
        <listener>  
            <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  
        </listener>  
        
        
    <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:applicationContext.xml</param-value>
        </init-param>
    </servlet>
    
    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        
        <url-pattern>*.do</url-pattern>
    </servlet-mapping>
           
      
      
       <filter>  
        <filter-name>openSessionInViewFilter</filter-name>  
        <filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>  
        <init-param>  
          <param-name>singleSession</param-name>  
          <param-value>true</param-value>  
        </init-param>  
      </filter>  
         
       <filter-mapping>  
        <filter-name>openSessionInViewFilter</filter-name>  
        <url-pattern>*.do</url-pattern>  
      </filter-mapping>  
         
      <welcome-file-list>  
        <welcome-file>index.jsp</welcome-file>  
      </welcome-file-list>  
    </web-app>

4.去掉struts.xml,在applicationContext.xml上添加springmvc的视图解析器和上传文件的配置：

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

            </property>  
            
            <property name="configLocation" value="classpath:hibernate.cfg.xml"/>  
             
            
            
            <property name="mappingLocations" 
            value="classpath:com/hsp/domain/*.hbm.xml"></property>

        </bean>  
       
         
        <tx:advice id="txAdvice" transaction-manager="transactionManager">  
              
            <tx:attributes>

            <aop:pointcut id="txPointcut" expression="execution(* com.hsp.service..*.*(..))" />  
            <aop:advisor advice-ref="txAdvice" pointcut-ref="txPointcut" />  
        </aop:config>  
    </beans>

5.com.hsp.action的LoginAction.java改动成springmvc的风格：

package com.hsp.action;
    
    import javax.servlet.http.HttpServletRequest;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    import com.hsp.domain.User;
    import com.hsp.service.Inter.UserService;
    import com.hsp.utils.LoadPhoto;
    
    @Controller//用来标注当前类是springmvc控制类
    //@RequestMapping("/user")//如果要加上就相当与struts的namespace
    public class LoginAction{
    	
    	@Autowired
    	private UserService userService;
    	
    	@RequestMapping("/login.do")
    	public String login(User user,HttpServletRequest request){
    		user=userService.checkUser(user);
    		if(user!=null)
    		{
    			request.setAttribute("message","恭喜你，登录成功！");
    			return "success";
    		}
    		else
    		{
    			request.setAttribute("message","密码或用户名有误！");
    			return "login";
    		}
    	}
    		
    }

6.com.hsp.utils的LoadPhoto.java修改如下：

package com.hsp.utils;
    
    import java.io.File;
    import java.io.FileNotFoundException;
    import java.io.FileOutputStream;
    import java.io.IOException;
    import java.io.OutputStream;
    import java.text.SimpleDateFormat;
    import java.util.Date;
    import java.util.Random;
    import java.util.UUID;
    
    import javax.servlet.http.HttpServletRequest;
    
    import org.springframework.web.multipart.MultipartHttpServletRequest;
    import org.springframework.web.multipart.commons.CommonsMultipartFile;
    
    public class LoadPhoto {
    	
    	public String uploadFengmian(String fileFileName,HttpServletRequest request){
    		
    		//转换request
    		MultipartHttpServletRequest rm=(MultipartHttpServletRequest)request;
    		//获得文件
    		CommonsMultipartFile cfile=(CommonsMultipartFile)rm.getFile(fileFileName);
    		//获得文件的字节数组
    		byte[] bfile=cfile.getBytes();
    		String filename="";
    		//获得当前时间
    		SimpleDateFormat format=new SimpleDateFormat("yyyyMMddHHmmssSSS");
    		filename=format.format(new Date());
    		Random random=new Random();
    		//获得三位随机数
    		for(int i=0;i<3;i++)
    		{
    		     filename =filename+random.nextInt(9);
    		}
    		//获取原始文件名
    		String origFileName=cfile.getOriginalFilename();
    		//xxx.jsp/png/...
    	    String suffix=origFileName.substring(origFileName.lastIndexOf("."));
    		//拿到项目的部署路径
    		String path=request.getSession().getServletContext().getRealPath("/");
    		OutputStream out=null;
    		try {
    			out=new FileOutputStream(new File(path+"/upload/"+filename+suffix));
    			out.write(bfile);
    			out.flush();
    			out.close();
    		} catch (Exception e) {
    			e.printStackTrace();
    		}
    		return filename+suffix;
    	}
    
    }

7.这样就可以了。  
其实从springmvc的写法上可以看出它与servlet有点像，两者也都是默认原型(prototype)模式的，而struts默认是单例(singleton)模式。经历过struts1的都知道struts获取数据是通过setter 和getter，而servlet、springmvc是直接有参数把值从前台带到后台。
