懒得笔记5 spring aop 整合hibernate 事务管理

1，在xml 中加上

          a) 加上对应的xsd文件spring-aop.xsd 

             xmlns:aop="http://www.springframework.org/schema/aop"

            http://www.springframework.org/schema/aop
             http://www.springframework.org/schema/aop/spring-aop-4.1.xsd"

           b) beans.xml <aop:aspectj-autoproxy />   // 表明自动产生代理

2，

      

       后面三个包。。不然各种错。。不知道要怎么样才知道要导入哪种包。

3，annotation 和 xml 两种方式 

 xml要掌握

4，spring 整合 hibernate

    a， 引入 data common 包  hibernate 等。。。根据报的错去导入

    b， 生成sessionFactory

            spring 整合 hibernate使用annotation 

          

<bean id="sessionFactory"
		class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
		<property name="dataSource" ref="dataSource" /> <!-- sessionFactory 织入对象 -->
		<property name="annotatedClasses"> <!-- 指明数据对象 -->
			<list>
				<value>com.model.User</value>
				<value>com.model.Log</value>
			</list>
		</property>
		<property name="hibernateProperties"> <!-- 可以设置若干属性 -->
			<props>
				<prop key="hibernate.dialect">
					org.hibernate.dialect.MySQLDialect
				</prop>
				<prop key="hibernate.show_sql">true</prop>
			</props>
		</property>
	</bean>

声明式的事务管理

5, 声明式的事务管理   实现在DAO这一层

    a, 加入 

xmlns:tx="http://www.springframework.org/schema/tx"

 xsi:schemaLocation="

       http://www.springframework.org/schema/tx
        http://www.springframework.org/schema/tx/spring-tx.xsd

  b, 加入 

     <bean id="txManager"
class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>

<tx:annotation-driven transaction-manager="txManager"/>

c , 在事务的地方加上

  @Transactional(readOnly=true) 如

  

@Transactional 
	public void add(User user) {
		
			userDAO.save(user);
			Log log = new Log();
			log.setMsg("a user saved!");
			logDAO.save(log);
		
	}
