SSH项目启动报错纠错记录

今天在进行项目启动时项目发生了如下的报错:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'depBiz' defined in file [D:\javaProject\javeErp\JavaEE_Erp\erp_biz\target\classes\applicationContext_biz.xml]: Cannot resolve reference to bean 'depDao' while setting bean property 'depDao'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'depDao' defined in file [D:\javaProject\javeErp\JavaEE_Erp\erp_dao\target\classes\applicationContext_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 file [D:\javaProject\javeErp\JavaEE_Erp\erp_dao\target\classes\applicationContext_datasource.xml]: Invocation of init method failed; nested exception is org.hibernate.MappingException: Could not get constructor for org.hibernate.persister.entity.SingleTableEntityPersister

于是检查了 depBiz，depDao的配置文件发现并没有什么错误,想到前一天做了权限测试的相关操作，于是检查了权限相关的配置文件，发现在Emp.hbm.xml中我增加了一条多对多的配置项，在检查Emp实体类是发现没有定义相关的List变量。

项目重启后没有发现问题，在进行hbm.xml配置时一定要认真检查在实体类中是否缺少了变量
