解决org.hibernate.ObjectDeletedException: deleted object would be re-saved by cascade (remove delete

相关代码：===============================================public class VoteQuestion {    private Set options = new HashSet();    。。。  /**  * @hibernate.set cascade = "all" table = "VOTE_OPTION" inverse =  *                "true" lazy = "true" order-by = "id"  *   * @hibernate.collection-one-to-many class =  *                                   "eorg.etoken.pojo.VoteOption"  *   * @hibernate.collection-key column = "QUESTION_ID"  */ public Set getOptions() {        return options; } } public class VoteOption {    private VoteQuestion question;    。。。。  /**  * @hibernate.many-to-one class = "eorg.etoken.pojo.VoteQuestion" cascade =  *                        "none" not-null = "true" column = "QUESTION_ID"  *                        update = "false"  */ public VoteQuestion getQuestion() {       return question; } } public class VoteServiceImpl{ 。。。 public void deleteVoteOption(int optionId) {      Transaction tx = session.beginTransaction();      VoteOption option = (VoteOption) session.load(VoteOption.class, new Long(optionId));      session.delete(option);      tx.commit(); }} =============================================== 当调用VoteServiceImpl的deleteVoteOption方法时，就会抛出下列Exception:org.hibernate.ObjectDeletedException: deleted object would be re-saved by cascade (remove deleted object from associations) 原因是votequestion与voteoption有连带关系，不能直接删除voteoption，而应该从votequestion里remove voteoption！ 因此上面的deleteVoteOption方法只需要修改一行即可，见下面代码 =============================================== public void deleteVoteOption(int optionId) {      Transaction tx = session.beginTransaction();      VoteOption option = (VoteOption) session.load(VoteOption.class, new Long(optionId));      option.getQuestion().getOptions().remove(option);      tx.commit(); }===============================================
