一、概述

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

二、整合步骤

整合前准备：

持久化类：

@Entity
publicclassBook
{
privateIntegerid;
privateStringbookName;
privateStringisbn;
privateintprice;
privateintstock;
publicIntegergetId()
{
returnid;
}
publicvoidsetId(Integerid)
{
this.id=id;
}
publicStringgetBookName()
{
returnbookName;
}
publicvoidsetBookName(StringbookName)
{
this.bookName=bookName;
}
publicStringgetIsbn()
{
returnisbn;
}
publicvoidsetIsbn(Stringisbn)
{
this.isbn=isbn;
}
publicintgetPrice()
{
returnprice;
}
publicvoidsetPrice(intprice)
{
this.price=price;
}
publicintgetStock()
{
returnstock;
}
publicvoidsetStock(intstock)
{
this.stock=stock;
}
publicBook(Integerid,StringbookName,Stringisbn,intprice,intstock)
{
super();
this.id=id;
this.bookName=bookName;
this.isbn=isbn;
this.price=price;
this.stock=stock;
}
}

Dao层：

publicinterfaceBookDao
{
publicStringfindBookById(intid);

publicvoidsaveBook(Bookbook);
}

DaoImpl:

@Repository
publicclassBookDaoImplimplementsBookDao
{
@Autowired
privateSessionFactorysessionFactory;

//获取和当前线程绑定的Seesion
privateSessiongetSession()
{
returnsessionFactory.getCurrentSession();
}
publicStringfindBookById(intid)
{
Stringhql="SELECTbookNamefromBookwhereid=?";
Queryquery=getSession().createQuery(hql).setInteger(0,id);
Stringstr=query.uniqueResult().toString();
returnstr;
}
publicvoidsaveBook(Bookbook)
{
getSession().save(book);
}
}

Service层：

publicinterfaceBookService
{
publicStringfindBookById(intid);
publicvoidsaveBook(Bookbook);
}

ServiceImpl：

@Service
publicclassBookServiceImplimplementsBookService
{
@Autowired
privateBookDaobookDao;
publicStringfindBookById(intid)
{
returnbookDao.findBookById(id);
}
publicvoidsaveBook(Bookbook)
{
bookDao.saveBook(book);

}
}

1、加入Hibernate

加入hibernatejar包
添加Hibernate的配置文件：hibernate.cfg.xml
org.hibernate.dialect.MySQL5Dialect true update
编写持久化类对应的.hbm.xml文件

2、加入Spring

加入springjar包

加入Spring配置文件

<context:component-scanbase-package="com.demo.ssm"></context:component-scan>

<!--配置Spring声明式事务-->
<beanid="transactionManager"class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<propertyname="sessionFactory"ref="sessionFactory"></property>
</bean>
<!--配置事务事务属性-->
<tx:adviceid="txAdvice"transaction-manager="transactionManager">
<tx:attributes>
<tx:methodname="get*"read-only="true"/>
<tx:methodname="*"/>
</tx:attributes>
</tx:advice>
<!--配置事务切点，并把切点和事务属性关联起来-->
<aop:config>
<aop:pointcutexpression="execution(*com.demo.ssm.daoImpl.*.*(..))"id="txPointcut"/>
<aop:advisoradvice-ref="txAdvice"pointcut-ref="txPointcut"/>
</aop:config>

3、编写测试类

publicclassBookDaoImplTest
{
privateApplicationContextcontext=null;
privateBookServicebookService=null;

{
context=newClassPathXmlApplicationContext("applicationContext.xml");
bookService=context.getBean(BookService.class);
}
@Test
publicvoidtest()
{
DataSourcedataSource=(DataSource)context.getBean(DataSource.class);
System.out.println(dataSource);
}
@Test
publicvoidtest2()
{
StringbookName=bookService.findBookById(1);
System.out.println(bookName);
}

@Test
publicvoidtest3()
{
bookService.saveBook(newBook(2,"android源码分析","1002",45,10));
}
}
