java - HIBERNATE 在更新对象时抛出错误 :"a different object with the same identifier value was already associated with the session "

Question

更新对象时无法更新并抛出上述错误

PublishedAssessmentData associatepublishobj = (PublishedAssessmentData) associatePublishedobjectdata.get(i);                  
PublishedAssessmentData existing_publishobj = service.transferupdatedpublishedassessments(associatepublishobj,sbipublishobj);                     
openSession.saveOrUpdate(existing_publishobj);

Answer 1

唯一的原因可能是，您从 Hibernate 获取了对象，然后再次尝试 saveOrUpdate。您之前在 Session 中保存过对象，并且您正在尝试再次保存它。

在该对象关联或获取的 session 上调用 commit。
