• 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:context="http://www.springframework.org/schema/context"

        xsi:schemaLocation="

            ">
       <!-- 01.C3p0 数据源 -->
       <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <!-- 设值注入,本质上使用的是类的set方法 -->

      <!-- 1.1 SessionFactory -->
      <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource" ></property>
        <property name="hibernateProperties">
          <props>
                  <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</prop>

          </props>
        </property>  
        
        <property name="mappingLocations" value="classpath:cn/happy/beans/Stock.hbm.xml"></property>
      </bean>
      
      <!-- dao -->
      <bean id="stockDao" class="cn.happy.dao.impl.StockDAOImpl">
        <property name="sessionFactory" ref="sessionFactory"></property>
      </bean>

       </bean>
       
       <!-- 第三种:AspectJ AOP 配置事务 -->
       <tx:advice id="txAdvice" transaction-manager="transactionManager">
           <tx:attributes>
             <tx:method name="save*" isolation="DEFAULT" propagation="REQUIRED"/>

       </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
