Error creating bean with name 'txManager' defined in class path resource [beans.xml]

错误信息：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'txManager' defined in class path resource [beans.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'sessionFactory' of bean class [org.springframework.jdbc.datasource.DataSourceTransactionManager]: Bean property 'sessionFactory' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

----------------------------------------------------------
beans.xml配置如下：

运行出错，求高手解答

<bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>

应该是不能加上这：
<property name="sessionFactory" ref="sessionFactory"></property>

我觉得可以改成
<property name="dataSource" ref="dataSource"></property>
试试。。。

这个两个怎么没有ref配置？ 应该是这两个property的配置没有成功找不到proxytargetclass或者transactionattributes他 我没这么干过。不知道这两个是你自己的 还是配置中就有的 你自己再修改下吧
