错误代码如下：
严重: 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 'boardDao': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.springframework.orm.hibernate3.HibernateTemplate com.baobaotao.dao.BaseDao.hibernateTemplate; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'hibernateTemplate' defined in class path resource [baobaotao-dao.xml]: Cannot resolve reference to bean 'sessionFactory' while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [baobaotao-dao.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'packagesToScan' of bean class [org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean]: Bean property 'packagesToScan' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

Answer 1

packagesToScan 这个属性在 spring 3.1以后才有 ，在你的classpath下检查一下你用的jar版本对不对
