Error creating bean with name 'userDAO' defined in class path resource [applicationContext.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 [applicationContext.xml]: Invocation of init method failed; nested exception is org.hibernate.InvalidMappingException: Could not parse mapping document from invalid mapping

Answer 1

使用HIBERNATE时映射文件有问题

Answer 2

这是spring配置文件报错 就是说你在配置实体类的value的时候 类型不匹配 比如你的实体类里定义了一个 private int age; int类型 而你在配置文件里注入的是<constructor-arg value="中文" index="3" type="int"></constructor-arg>中文 无法转换成int 就报错了！
