创建项目之前：我们需要导入我们需要的Hibernate和Struts2和Spring的相关架包。（博客自创,如有问题请留言博主，拒绝盗版，支持正版http://www.cnblogs.com/WuXuanKun/）
项目架构图：
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
我们需要搭建各个层：层次如上右图
1.搭建beans层：
①创建一个实体类Stock。
/**
* 股票类
*/
public class Stock {
private int sid; //股票编号
private String sname;//股票名称
private int scount; //股数
public int getSid() {
return sid;
}
public void setSid(int sid) {
this.sid = sid;
}
public String getSname() {
return sname;
}
public void setSname(String sname) {
this.sname = sname;
}
public int getScount() {
return scount;
}
public void setScount(int scount) {
this.scount = scount;
} }
Stock.java
②我们创建小配置。Stock.hbm.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="cn.happy.beans">
<class name="Stock" table="Stock">
<id name="sid">
<generator class="native"></generator>
</id>
<property name="sname"/>
<property name="scount" column="COUNT"/>
</class> </hibernate-mapping>
Stock.hbm.xml
2.搭建DAO层：
①创建Stock接口
/**
* Stock接口
*/
public interface IStockDAO {
public int addStock(Stock stock);
}
IStockDAO
②实现接口
import java.io.Serializable; import org.hibernate.SessionFactory;
import org.hibernate.classic.Session;
import org.springframework.jdbc.core.support.JdbcDaoSupport; import cn.happy.beans.Stock;
import cn.happy.dao.IStockDAO; public class StockDAOImpl implements IStockDAO{
//在这里定义一个SessionFactory变量
private SessionFactory sessionFactory; @Override
public int addStock(Stock stock) {
Session session = sessionFactory.getCurrentSession();
Serializable count=session.save(stock);
Integer cc=(Integer)count;
return cc.intValue();
} public SessionFactory getSessionFactory() {
return sessionFactory;
} public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
} }
StockDAOImpl
3.搭建Service服务层：
①创建接口StockService
public interface IStockService {
public int saveStock(Stock stock);
}
IStockService
②实现上面的接口
public class StockServiceImpl implements IStockService {
//服务层 需要一个dao的对象
private IStockDAO dao;
@Override
public int saveStock(Stock stock) {
return dao.addStock(stock);
}
public IStockDAO getDao() {
return dao;
}
public void setDao(IStockDAO dao) {
this.dao = dao;
}
}
StockServiceImpl
4.搭建action层
public class StockAction extends ActionSupport implements ModelDriven<Stock>{
private Stock stock;
private IStockService service;
//重点代码：在无参构造中new一个Stock对象。
private StockAction(){
stock=new Stock();
}
//execute()方法是ActionSupport的一个方法。save()一条数据;判断是否插入一条记录。要是count大于0，证明页面有一条数据插入。成功跳入index.jsp页面。否则跳入add.jsp页面。
public String execute(){
int count = service.saveStock(stock);
if (count>0) {
return SUCCESS;
}else {
return INPUT;
}
}
//getModel是ModelDriven<Stock>的一个方法
@Override
public Stock getModel() {
return stock;
}
public Stock getStock() {
return stock;
}
public void setStock(Stock stock) {
this.stock = stock;
}
public IStockService getService() {
return service;
}
public void setService(IStockService service) {
this.service = service;
}
}
StockAction继承ActionSupport并且实现ModelDriven
5.搭建两个jsp页面：
<%@ 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>My JSP 'index.jsp' starting page</title>
</head> <body>
<form action="addStock" method="post">
股票名称：<input type="text" name="sname"/>
股票股数：<input type="text" name="scount"/>
<input type="submit" value="提交"/>
</form>
</body>
</html>
add.jsp页面（插入数据页面）
<%@ 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>My JSP 'index.jsp' starting page</title>
</head> <body>
成功页面
</body>
</html>
index.jsp(成功页面)
6.创建Struts.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<package name="default" namespace="/" extends="struts-default">
<action name="addStock" class="stockAction">
<result name="success">/index.jsp</result>
<result name="input">/add.jsp</result>
</action> </package>
</struts>
struts.xml
7.创建连接具体数据库：本案例用Mysql数据库为例：搭建jdbc.properties
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc\:mysql\:///test
jdbc.username=wu
jdbc.password=xuan
jdbc.properties
8.创建大配置applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"

applicationContext.xml
9.该项目已经成功搭建完毕。可以做一个单测。（该步骤可以省略）
//购买股票测试
@Test
public void addStockTest() {
ApplicationContext ctx=new ClassPathXmlApplicationContext("applicationContext.xml");
IStockService service=(IStockService)ctx.getBean("stockService");
Stock stock=new Stock();
stock.setSname("Y2162基金");
stock.setScount(23);
service.saveStock(stock);
System.out.println("OK!");
}
MyTest测试类
10.启动项目：
