事务注入出错,测试取transactionManager的时候报下面错误.

去掉下面几行取sessionFactory时正常可以取到。求解释~


<!-- transactionManager -->
	<bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
			<property name="sessionFactory">
				<ref bean="sessionFactory"/>

异常来自这段代码:

if ( ConnectionProvider.class.equals( unwrapType ) ||
    DriverManagerConnectionProviderImpl.class.isAssignableFrom( unwrapType ) ) {
    return (T) this;
} else {
    throw new UnknownUnwrapTypeException( unwrapType );
}
这里指明,Connection 需要从 javax.sql.DataSource 中获取。

请确保删除 hibernate.cfg.xml 配置文件中定义的数据源,并将 Spring 定义的 DataSource 注入 LocalSessionFactoryBean。

就像这样:

<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="configLocation">
        <value>classpath:hibernate/hibernate.cfg.xml</value>
    </property>
    <property name="dataSource" ref="dataSource" />
</bean>

回复 @lmtoo : 请问指定hibernate.connection.provider_class属性为什么呢,难道要自己写一个classname.of.ConnectionProvider吗?大神求指教!!!

回复 @vooctj : 可以的,但是hibernate配置文件中必须指定hibernate.connection.provider_class属性,否则hibernate会使用ConnectionProvider来获取链接,而不是DataSource

回复 @zfc827 : 将数据源配置到hibernate配置文件中,Spring是可以获得的

因为hibernate 和 spring 提供的事务管理器需要使用同一个数据源,如果将数据源配置在 hibernate 配置文件中,那么 spring 就无法得到 hibernate 的数据源。

为什么必须在spring中配置数据源呢?在hibernate中不可以吗?

如果hibernate配置文件中没有指定数据源,则必须在org.springframework.orm.hibernate4.LocalSessionFactoryBean中指定数据源,因为HibernateTransactionManager依赖数据源,你的hibernate.cfg.xml中肯定没有指定hibernate.connection.provider_class属性

这个问题,俺当年也遇到过,是事务管理器的问题。

可用tx事务取代之。
