org.springframework.orm.hibernate3.HibernateSystemException: a different object with the same identifier value was already associated with the session: [com.remotediagnose.model.Patient#3]; nested exception is org.hibernate.NonUniqueObjectException: a different object with the same identifier value was already associated with the session: [com.remotediagnose.model.Patient#3]
估计是你修改用了add方法. 换成merge或者update应该就可以了.
