SSH-Hibernate+Struts2+Spring的股票项目整合

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"

      <aop:pointcut expression="execution(* *..service.*.*(..))" id="pointCut"/>
      <aop:advisor advice-ref="txAdvice" pointcut-ref="pointCut"/>

   </aop:config>

</beans>

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
