Question

Spring+hibernate,怎么关闭Spring对hibernate的事务控制

因为相关需求的缘故，要做大数据批量导入，框架用的SSH。做大批量数据插入如果不关闭spring的事务管理，事务会对没一条数据自动插入，那么一条一条的插入，会非常慢。附配置截图。

第一步：在beans.xml中配置：

<bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<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"

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" class="edu.zust.dao.impl.TuserDAOImpl">
<!-- 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" class="edu.zust.service.tuserService">
<property name="tuserdao" ref="u" />
</bean>

<!--利用Spring配备数据库的连接数据源-->
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<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" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<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" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<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>
