SSH程序框架之Spring与HIbernate整合

spring整合hibernate 有两种方式 1、注解方式 2、xml方式实现

　　Spring整合Hibernate有什么好处？

　　1、由IOC容器来管理Hibernate的SessionFactory

　　2、让Hibernate使用上Spring的声明式事务

1.xml方式：

大概架构：

我们将会创建一个账户类，实现添加的功能

首先先添加Spring 和 HIbernate的jar包节点：

  <dependencies>
         <dependency>
             <groupId>junit</groupId>
             <artifactId>junit</artifactId>
             <version>4.3</version>
             <scope>test</scope>
         </dependency>

         <!--jta的jar包-->
         <dependency>
             <groupId>javax.transaction</groupId>
             <artifactId>jta</artifactId>
             <version>1.1</version>
         </dependency>

         <!--mysql数据库驱动-->
         <dependency>
             <groupId>org.wisdom-framework</groupId>
             <artifactId>mysql-connector-java</artifactId>
             <version>5.1.34_1</version>
         </dependency>

         <dependency>
             <groupId>org.hibernate</groupId>
             <artifactId>hibernate-core</artifactId>
             <version>5.0.6.Final</version>
         </dependency>

         <!--以上是HIbernate的jar包配置-->

         <!--下面是Spring相关的jar包配置-->
         <!--c3p0-->
         <dependency>
             <groupId>com.mchange</groupId>
             <artifactId>c3p0</artifactId>
             <version>0.9.5.2</version>
         </dependency>

         <!--AOP的相关jar-->
         <dependency>
             <groupId> org.aspectj</groupId >
             <artifactId> aspectjweaver</artifactId >
             <version> 1.8.7</version >
         </dependency>

         <dependency>
             <groupId>org.springframework</groupId>
             <artifactId>spring-context</artifactId>
             <version>4.2.0.RELEASE</version>
         </dependency>

         <!--Spring-ORM-->
         <dependency>
             <groupId>org.springframework</groupId>
             <artifactId>spring-orm</artifactId>
             <version> 4.2.2.RELEASE</version>
         </dependency>

     </dependencies>

Stock(账户类)：

 package cn.happy.beans;

 /**
  * 股票类
  * Created by CKW on 2017/4/2.
  */
 public class Stock {
     private Integer sid;//编号
     private String sname;//名称
     private Integer scount;//余额股

     public Stock(String sname, Integer scount) {
         this.sname = sname;
         this.scount = scount;
     }

     public Integer getSid() {
         return sid;
     }

     public void setSid(Integer sid) {
         this.sid = sid;
     }

     public String getSname() {
         return sname;
     }

     public void setSname(String sname) {
         this.sname = sname;
     }

     public Integer getScount() {
         return scount;
     }

     public void setScount(Integer scount) {
         this.scount = scount;
     }
 }

dao层接口(StockDao)：

 package cn.happy.dao;

 import cn.happy.beans.Stock;

 /**
  * Created by CKW on 2017/4/2.
  */
 public interface StockDao {
     //添加
     public int addStock(Stock stock);
 }

dao层实现类(StockDaoImpl)：

 package cn.happy.dao.impl;

 import cn.happy.beans.Stock;
 import cn.happy.dao.StockDao;
 import org.hibernate.Session;
 import org.hibernate.SessionFactory;

 import java.io.Serializable;

 /**
  * Created by CKW on 2017/4/2.
  */

 public class StockDaoImpl implements StockDao {

     //植入一个工厂对象
     private SessionFactory sessionFactory;

     public int addStock(Stock stock) {
         Session session = sessionFactory.getCurrentSession();
         Serializable count = session.save(stock);
         return (Integer)count;
     }

     public SessionFactory getSessionFactory() {
         return sessionFactory;
     }

     public void setSessionFactory(SessionFactory sessionFactory) {
         this.sessionFactory = sessionFactory;
     }
 }

service层接口(AccountService)：

 package cn.happy.service;

 import cn.happy.beans.Stock;

 /**
  * Created by CKW on 2017/4/2.
  */
 public interface AccountService {

     //添加
     public int addStock(Stock stock);

 }

service层实现类()：

 package cn.happy.service.impl;

 import cn.happy.beans.Stock;
 import cn.happy.dao.StockDao;
 import cn.happy.service.AccountService;

 import org.springframework.transaction.annotation.Transactional;

 /**
  * Created by CKW on 2017/4/2.
  */
 public class AccountServiceImpl implements AccountService {
     private StockDao stockDao;

     @Transactional
     public int addStock(Stock stock) {
         return stockDao.addStock(stock);
     }

     public StockDao getStockDao() {
         return stockDao;
     }

     public void setStockDao(StockDao stockDao) {
         this.stockDao = stockDao;
     }
 }

查看数据库：添加成功！
