Java 无法使用Hibernate从PostgreSQL获取BLOB字段

我的PostGreSQL中有一个BLOB字段，我正在尝试使用hibernate获取该字段。下面是相同的快照：

表格

现在我想获取这个字段并将其显示给用户。为此，我使用了

byte[]

数组。下面是我的代码：

entity.java

@Lob
@Column(name = "MAIL_BODY",length=100000)
public Byte[] getMailBody() {
    return mailBody;
}
public void setMailBody(Byte[] mailBody) {
    this.mailBody = mailBody;
} 

Session session=comTtEflMailDataServiceDao.getCurrentSessionPortal();
Criterion criterion=Restrictions.eq("headerSeqNo", "40011532018");
comTtEflMailData=comTtEflMailDataServiceDao.getListByFilter(criterion, session);

criteria = currSession.createCriteria(getPersistentClass());
System.out.println(3);
criteria.add(criterion);
System.out.println(2);
resultset = (T) criteria.uniqueResult();

service.java

@Lob
@Column(name = "MAIL_BODY",length=100000)
public Byte[] getMailBody() {
    return mailBody;
}
public void setMailBody(Byte[] mailBody) {
    this.mailBody = mailBody;
} 

Session session=comTtEflMailDataServiceDao.getCurrentSessionPortal();
Criterion criterion=Restrictions.eq("headerSeqNo", "40011532018");
comTtEflMailData=comTtEflMailDataServiceDao.getListByFilter(criterion, session);

criteria = currSession.createCriteria(getPersistentClass());
System.out.println(3);
criteria.add(criterion);
System.out.println(2);
resultset = (T) criteria.uniqueResult();

DAO.java

@Lob
@Column(name = "MAIL_BODY",length=100000)
public Byte[] getMailBody() {
    return mailBody;
}
public void setMailBody(Byte[] mailBody) {
    this.mailBody = mailBody;
} 

Session session=comTtEflMailDataServiceDao.getCurrentSessionPortal();
Criterion criterion=Restrictions.eq("headerSeqNo", "40011532018");
comTtEflMailData=comTtEflMailDataServiceDao.getListByFilter(criterion, session);

criteria = currSession.createCriteria(getPersistentClass());
System.out.println(3);
criteria.add(criterion);
System.out.println(2);
resultset = (T) criteria.uniqueResult();

但是，当我运行代码时，会出现以下错误：

org.hibernate.exception.GenericJDBCException: could not execute query 
Caused by: java.sql.SQLException: Numeric Overflow

如何解决此问题？

您确定此异常与

BLOB

字段读取相关吗？能否提供完整的堆栈跟踪以及与查询实体字段相关的所有内容。@SternK我解决了这个问题。你是对的。这并不是因为水滴场。谢谢
