setter的参数类型是否与getter的返回类型匹配？

Question

我正在尝试学习如何使用DAO和BO类,我收到以下错误

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [spring/database/Hibernate.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'annotatedClasses' of bean class [org.springframework.orm.hibernate3.LocalSessionFactoryBean]: Bean property 'annotatedClasses' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

Hibernate.xml

    <property name="packagesToScan" value="data" />
    <property name="hibernateProperties">

            <prop key="hibernate.current_session_context_class">thread</prop>
            <prop key="hibernate.transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.hbm2ddl.auto">update</prop>
        </props>
    </property>
</bean> 

我不知道错误来自哪里,因为我的countries.java和customer.java类中的getter和setter方法都是正确的!

有人知道什么是错的吗？(如果你需要看到任何其他类只是添加一个评论说哪些类和il发布它们)

谢谢

它实际上是抱怨annotatedClasses会话工厂的属性,你使用的LocalSessionFactoryBean是没有它的(你已经注释掉AnnotationSessionFactoryBean它确实有它).
