关于 Spring 声明式事务管理！！！
没添加这个的时候能正常运行。添加了事务配置错误如下！！！
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userAction' defined in class path resource [applicationContext.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'service' of bean class [com.joker.web.UserAction]: Bean property 'service' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

[最优解释]
1. com.joker.web.UserAction中service没有Setter方法？
--------------------------
2. 在定义service时应该用接口，不要用实现类

applicationContext.xml 的配置信息如下
<!-- 配置 Hibernate 的事物管理器 -->
<!-- 使用 HibernateTransactionManager 类实现基于 Hibernate 的事物管理器 -->
<bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<!-- HibernateTransactionManager bean 需要依赖注入一个 SessionFactory bean 的引用 -->
