Java Bean属性数据源在Spring中不可写+；冬眠3

我搜索了很多地方，但没有找到以下错误的解决方案：

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'hibernateDaoImpl' defined in class path resource [spring.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'dataSource' of bean class [com.springhibernate.example.HibernateDaoImpl]: Bean property 'dataSource' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

线程“main”org.springframework.beans.factory.BeanCreationException中的异常：创建在类路径资源[spring.xml]中定义的名为“hibernateDaoImpl”的bean时出错：设置属性值时出错；嵌套异常为org.springframework.beans.NotWritablePropertyException:bean类[com.springhibernate.example.HibernateDoImpl]的无效属性“dataSource]：bean属性“dataSource”不可写或具有无效的setter方法。setter的参数类型与getter的返回类型匹配吗？

例外情况来自以下spring xml文件配置：

还没有收到你的回音，但我要冒险一试

通常，对于Hibernate DAO对象，您需要的是sessionFactory而不是数据源。因此，为DAO提供一种设置sessionFactory的方法（例如，setter或构造函数-我更喜欢构造函数，因为它不需要是可变的）

配置

 <bean id="hibernateDaoImpl" class="com.springhibernate.example.HibernateDaoImpl">
   <constructor-arg ref="sessionFactory"/>
 </bean>

让我们看看com.springhibernate.example.HibernateDaoImpl，它说“Bean属性”数据源“不可写…”让我把它分部分发布，它不会一次全部运行。第一部分如下：

 <bean id="hibernateDaoImpl" class="com.springhibernate.example.HibernateDaoImpl">
   <constructor-arg ref="sessionFactory"/>
 </bean>
