Hibernate AssertionFailure:条目中的id为null(发生异常后不要刷新会话)

我试图在一个catch块中执行一些更新操作。冬眠例外ConstraintViolationException抛出如下

我正在使用Hibernate 4.3.6

try {
     services.entity.saveInstance(secQuestions)
}
catch(Exception e) {
     if(e instanceof org.hibernate.exception.ConstraintViolationException){
        userRegistrationRequest.requestProcessed = true
        infoMsg = userRegistrationRequest.infoMessage+' Exception: '+e.message
        userRegistrationRequest.infoMessage = infoMsg
        entityService.update(userRegistrationRequest)
        logger.info("Caught BaseApplicationException "+e.message)
        return;
 }

这是我的UserRegistrationRequest实体

@Audited
@javax.persistence.Entity
class UserRegistrationRequest implements IAmGroovy, Serializable, IVersionable {

@Autowired
protected transient Services         services;
protected answerOne;
protected answerTwo;
protected emailAddress;
protected firstName;
protected infoMessage;
protected lastName;
protected requestExpired;
protected requestProcessed;
SecurityQuestion securityQuestionOne;  
SecurityQuestion securityQuestionTwo; 
UserSecurityQuestions securityQuestions;
}

这是我的UserSecurityQuestions实体

@Entity
@Audited
public class UserSecurityQuestions implements IPersistentEntityInstance {

    private Long               id;
    private User               user;
    private SecurityQuestion   question1;
    private SecurityQuestion   question2;
    private String             answer1;
    private String             answer2;
    private String             hashString;
    private Timestamp          validThrough;
    private int                tries;
 }

尝试在catch块中执行更新时,我遇到以下错误

有人能帮帮我吗,有没有更好的方法来执行捕获块中的更新操作?

您可以尝试这样做:在不同的事务中保留这两个更新。如果try中出现异常,请回滚catch中的第一个事务,清除会话并启动一个新事务以在catch中更新。

    Transaction tx = null;
    try {
        tx = session.beginTransaction(); 
        services.entity.saveInstance(secQuestions);
        tx.commit();
    }
    catch(Exception e) {
        tx.rollback();
        session.clear();
        if(e instanceof org.hibernate.exception.ConstraintViolationException){
            Transaction tx1 = session.beginTransaction();
            userRegistrationRequest.requestProcessed = true
            infoMsg = userRegistrationRequest.infoMessage+' Exception: '+e.message
            userRegistrationRequest.infoMessage = infoMsg
            entityService.update(userRegistrationRequest);
            tx1.commit();
            logger.info("Caught BaseApplicationException "+e.message)
            return;
     }
}
