Springmvc案例1----基于spring2.5的采用xml配置-白红宇

首先是项目和所需要的包截图：

修改xml文件：

[html]
<?xml version="1.0" encoding="UTF-8"?>  
<web-app version="2.5"   
    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_2_5.xsd">  
    <servlet>  
        <servlet-name>dispatcherServlet</servlet-name>  
        <servlet-class>  
            org.springframework.web.servlet.DispatcherServlet  
        </servlet-class>  
        <init-param>  
            <param-name>contextConfigLocation</param-name>  
            <param-value>  
                /WEB-INF/hib-config.xml,/WEB-INF/web-config.xml,  
                /WEB-INF/service-config.xml,/WEB-INF/dao-config.xml  
            </param-value>  
        </init-param>  
        <load-on-startup>1</load-on-startup>  
    </servlet>  
    <servlet-mapping>  
        <servlet-name>dispatcherServlet</servlet-name>  
        <url-pattern>*.do</url-pattern>  
    </servlet-mapping>  
</web-app>  

增加web-config.xml

[html]
<?xml version="1.0" encoding="UTF-8"?>

增加service-config.xml

各类包的代码如下：

[html]
package com.sxt.po;  
  
import javax.persistence.Entity;  
import javax.persistence.GeneratedValue;  
import javax.persistence.GenerationType;  
import javax.persistence.Id;  
  
@Entity  
public class User {  
    private int id ;  
    private String name ;  
    @Id  
    @GeneratedValue(strategy=GenerationType.AUTO)  
    public int getId() {  
        return id;  
    }  
    public void setId(int id) {  
        this.id = id;  
    }  
    public String getName() {  
        return name;  
    }  
    public void setName(String name) {  
        this.name = name;  
    }  
      
}  

userDao

[html]
package com.sxt.dao;  
  
import org.springframework.orm.hibernate3.HibernateTemplate;  
  
import com.sxt.po.User;  
  
public class UserDao {  
    private HibernateTemplate hibernateTemplate ;  
      
    public void add(User u){  
        System.out.println("userDao.add()");  
        hibernateTemplate.save(u) ;  
    }  
    public HibernateTemplate getHibernateTemplate() {  
        return hibernateTemplate;  
    }  
  
    public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {  
        this.hibernateTemplate = hibernateTemplate;  
    }  
      
}  

userService

[html]
package com.sxt.service;  
  
import com.sxt.dao.UserDao;  
import com.sxt.po.User;  
  
public class UserService {  
    private UserDao userDao ;  
    public void add(String name){  
        System.out.println("UserService.add()");  
        User u = new User() ;  
        u.setName(name) ;  
        userDao.add(u) ;  
    }  
    public UserDao getUserDao() {  
        return userDao;  
    }  
    public void setUserDao(UserDao userDao) {  
        this.userDao = userDao;  
    }  
      
}  

userController

[html]
package com.sxt.action;  
  
import javax.servlet.http.HttpServletRequest;  
import javax.servlet.http.HttpServletResponse;  
  
import org.springframework.web.servlet.ModelAndView;  
import org.springframework.web.servlet.mvc.Controller;  
  
import com.sxt.service.UserService;  
  
public class UserController implements Controller{  
    private UserService userService ;  
    @Override  
    public ModelAndView handleRequest(HttpServletRequest req,  
            HttpServletResponse resp) throws Exception {  
        // TODO Auto-generated method stub  
        System.out.println("HelloController.handleRequest()");  
        req.setAttribute("a", "bbb") ;  
        userService.add(req.getParameter("name")) ;  
        return new ModelAndView("index2");  
    }  
    public UserService getUserService() {  
        return userService;  
    }  
    public void setUserService(UserService userService) {  
        this.userService = userService;  
    }  
      
}  

下面是显示层的jsp代码：

[html]
<%@ page language="java" import="java.util.*" pageEncoding="GB18030"%>  
<%  
String path = request.getContextPath();  
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";  
%>  
  
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

        姓名：<input type="text" name="name" />  
        登录：<input type="submit" value="登录">  
    </form>  
  </body>  
</html>  

index2.jsp

[html]
<%@ page language="java" import="java.util.*" pageEncoding="GB18030"%>  
<%  
String path = request.getContextPath();  
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";  
%>  
  
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
