Hibernate：无法创建javabean

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 'categorySecondService' defined in class path resource [applicationContext.xml]: Cannot resolve reference to bean 'categorySecondDao' while setting bean property 'categorySecondDao'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'categorySecondDao' defined in class path resource [applicationContext.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'sessionFactory' of bean class [shop.categorysecond.dao.CategorySecondDao]: Bean property 'sessionFactory' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

 

       原因1：application.xml文件中对<bean/>内部标签<property/>的name属性值不对，name属性值应和包含它的bean的set方法的后缀名一致（首字母小写）

       原因2：set，get方法错误，和属性名对应不上

       原因3：此处创建dao层的bean需要使用到SessionFactory，但是如果dao层的类没有完整继承HibernateDaoSupport类（ssh框架dao需要继承的持久化父类），既没办法创建sessionFactory，于是sessionFactory invalid的现象。
