Springmvc案例1----基于spring2.5的採用xml配置

首先是项目和所须要的包截图：

改动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>

添加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"
	xsi:schemaLocation="

	<bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">

	</bean>
	<bean id="userController" class="com.sxt.action.UserController">
		<property name="userService" ref="userService"></property>
	</bean>
</beans>

添加service-config.xml

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

<bean id="userService" class="com.sxt.service.UserService">
	<property name="userDao" ref="userDao"></property>
</bean>
</beans>

添加dao-config.xml

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

<bean id="userDao" class="com.sxt.dao.UserDao">

添加hib-config.xml

各类包的代码例如以下：

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;
	}

}

以下是显示层的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">
<html>
  <head>
    <base href="<%=basePath%>">

index2.jsp

<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
