如何让spring管理hibernate事务机制(annotation)

第一步：在beans.xml中配置：

 

  <bean id=”txManager”>
   <property name=”sessionFactory” ref=”sessionFactory” />
 </bean>
  <!– enable the configuration of transactional behavior based on annotations –>
  <tx:annotation-driven transaction-manager=”txManager”/>

 

第二步：什么方法上需要事务管理，就在该方法的service层上添加注解 @Transactional

  

 @Transactional
public void save(){
 tuserdao.save();
  }

 

第三步：创建session 只能为getCurrentSession（）

  Session session = sessionfactory.getCurrentSession();

 

 

全文beans.xml如下：

 

<?xml version=”1.0″ encoding=”UTF-8″?>
<beans xmlns=”http://www.springframework.org/schema/beans”
      xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance”
      xmlns:context=”http://www.springframework.org/schema/context”
      xmlns:tx=”http://www.springframework.org/schema/tx”
      xsi:schemaLocation=”http://www.springframework.org/schema/beans
          http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
          http://www.springframework.org/schema/context
          http://www.springframework.org/schema/context/spring-context-2.5.xsd
          http://www.springframework.org/schema/tx
          http://www.springframework.org/schema/tx/spring-tx-2.5.xsd“>

 <context:annotation-config/>   <!– Spring中annotation必须填写 –>

 <bean name=”u”>
    <!– 下面一行与<context:annotation-config/>后在TuserDAOImpl中写Resource等同 –>
    <!–<property name=”sessionfactory” ref=”sessionFactory” /> –>
 </bean>
 <bean id=”userService”>
    <property name=”tuserdao” ref=”u” />
 </bean>


<!–利用Spring配备数据库的连接数据源–>
<bean>
   <property name=”locations”>
       <value>classpath:jdbc.properties</value>
   </property>
</bean>

  <bean id=”dataSource” destroy-method=”close”
       class=”org.apache.commons.dbcp.BasicDataSource”>
   <property name=”driverClassName” value=”${jdbc.driverClassName}”/>
   <property name=”url” value=”${jdbc.url}”/>
   <property name=”username” value=”${jdbc.username}”/>
   <property name=”password” value=”${jdbc.password}”/>
 </bean>

<!– Spring整合hibernate给hibernate创建单例sessionFactory，并且利用Spring关联数据库  –>
 <bean id=”sessionFactory”>
   <property name=”dataSource” ref=”dataSource”/>        <!– 让Spring给这个sessionFactory关联上数据库 –>

   <property name=”annotatedClasses”>                     <!– 告诉hibernate哪些类被注解了 –>
     <list>
       <value>edu.zust.model.Tuser</value>
     </list>
   </property>
   <property name=”hibernateProperties”>                   <!– 指明hibernate配置属性 –>
     <props>
       <prop key=”hibernate.dialect”>org.hibernate.dialect.MySQLDialect</prop>
       <prop key=”hibernate.show_sql”>true</prop>
       <prop key=”hibernate.format_sql”>true</prop>
     </props>
   </property>
 </bean>

 

 <!-声明hibernate事务管理–>
 <bean id=”txManager”>
   <property name=”sessionFactory” ref=”sessionFactory” />
 </bean>
  <!– enable the configuration of transactional behavior based on annotations –>

 

<!–指明是用annotation方式–>
  <tx:annotation-driven transaction-manager=”txManager”/>
 
 
</beans>
