NHibernate.InvalidProxyTypeException
The following types may not be used as proxies:
SSO.Model.Entities.DEPART_DICTIONARY: method obj_address should be virtual
SSO.Model.Entities.PUB_SYSLOG: method obj_address should be virtual
SSO.Model.Entities.PUB_DEPATMENT_POINT: method obj_address should be virtual
SSO.Model.Entities.PUB_POINTUSER: method obj_address should be virtual
SSO.Model.Entities.PUB_POWER: method obj_address should be virtual
SSO.Model.Entities.PUB_USER_POINTUSER: method obj_address should be virtual
Description: HTTP 500.Error processing request.

Details: Non-web exception. Exception origin (name of application or object): NHibernate.

Exception stack trace:
at NHibernate.Cfg.Configuration.Validate () [0x00000] in <filename unknown>:0
at NHibernate.Cfg.Configuration.BuildSessionFactory () [0x00000] in <filename unknown>:0
at SSO.DAL.SessionFactory..cctor () [0x00000] in <filename unknown>:0

我的这些类中并没有obj_address这个方法，而且所有的都已经加了virtual，报这个错误是为什么呢？
