Springmvc案例1----基于spring2.5的采用xml配置

首先是项目和所需要的包截图：





修改xml文件：

<?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

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

增加service-config.xml

各类包的代码如下：

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

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

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

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：

<%@ 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">
