Hibernate大对象类型不匹配

Question

当我尝试在DAOimpl类中使用此方法更新hibernate中的条目时：

public void setVoiceMailUnread(int id) {
        Session session = sessionFactory.openSession();
        Transaction transaction = null;
        VoiceMail vm = (VoiceMail)session.load(VoiceMail.class, id);
        try {
            transaction = session.beginTransaction();
            vm.setRead(false);
            transaction.commit();
        } catch (HibernateException e) {
            if (transaction != null)
                transaction.rollback();
            e.printStackTrace();
        } finally {
            session.close();
        }
    }

我收到以下错误：

ERROR: ERROR: column "recording" is of type lo but expression is of type bigint Hint: You will need to rewrite or cast the expression. Position: 201

在我的实体类中，实例变量记录的类型为Blob：

@Entity
@Table(name = "VOICEMESSAGES")
public class VoiceMail implements Serializable {
     private int uniqueId;
     private int messageNumber;
     private String directory;
     private String context;
     private String macroContext;
     private String callerId;
     private String origTime;
     private String duration;
     private String flag;
     private String mailboxUser;
     private String mailboxContext;
     private Blob recording;
     private String label;
     private Boolean read;
     private String messageId;

.....

@Column(name = "RECORDING", unique = true, nullable = false)
@Lob
@JsonIgnore
public Blob getRecording() {
    return recording;
}

public void setRecording(Blob recording) {
    this.recording = recording;
}

也许我遗漏了与大型对象的anotations相关的内容，因为db中的记录列是“lo”类型。 谢谢你的回答！
