启动Tomecat时出了错.之前没有添加事务处理时.上面的代码是可以正常运行的.添加事务之后却出现以下错误
ERROR - Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userService' defined in ServletContext resource [/WEB-INF/applicationContext-hibernate.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'transactionManager' of bean class [dgut.ke.service.impl.UserService]: Bean property 'transactionManager' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?
Caused by:
org.springframework.beans.NotWritablePropertyException: Invalid property 'transactionManager' of bean class [dgut.ke.service.impl.UserService]: Bean property 'transactionManager' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?
解决办法

<bean id="userService"  parent="txProxyTemplate"  class="dgut.ke.service.impl.UserService">
    <property name="userDAO" ref="userDAO" />
</bean>
换成以下代码就可以正常运行了
 <bean id="userService" parent="txProxyTemplate">
      <property name="target">
           <bean class="dgut.ke.service.impl.UserService">
                <property name="userDAO" ref="userDAO"></property>
           </bean>
      </property>
 </bean>

请教一下为什么会出现这种情况?
哪位高手解释下,谢谢!!!

一样的问题,在此找到答案,谢了
曾试着这样
<bean id="userService" parent="txProxyTemplate">
<property name="target">
<bean class="dgut.ke.service.impl.UserService">
</bean>
</property>
</bean>
就是没想到要把DAO作为属性加进去
