【中文标题】Hibernate 和 HSQLDB 违反主键完整性约束【英文标题】:Primary key integrity constraint violation with Hibernate and HSQLDB 【发布时间】:2016-03-06 11:09:52 【问题描述】:大家早上好
我在 Hibernate 中使用 HSQLDB。我有一种情况,即使我设置了主键值,我仍然得到一个integrity constraint violation: NOT NULL check constraint; SYS_CT_10346 table: NUMBERS column: PK
。如下图所示。
SEVERE: integrity constraint violation: NOT NULL check constraint; SYS_CT_10346 table: NUMBERS column: PK

还有我的实体类

最后是我要执行的代码
public boolean saveNumbers(Set numbersSet)
try
Session session = HibernateUtil.getSessionFactory().openSession();
session.beginTransaction();
for (Iterator<Numbers> it = numbersSet.iterator(); it.hasNext();)
Numbers numbers = it.next();
if (numbers.getPk() == null)
numbers.setPk(new Integer(5));
session.save(numbers);
else
numbers = (Numbers) session.merge(numbers);
session.saveOrUpdate(numbers);
session.getTransaction().commit();
return true;
catch (HibernateException he)
he.printStackTrace();
return false;
session.save(numbers);
抛出异常
即使我手动设置主键,如上面的示例所示,它仍然会引发异常。 我试图设置如下所示的注释,但这仍然给了我同样的例外。
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Basic(optional = false)
@Column(name = "PK", unique = true, nullable = false)
非常感谢您的帮助
谢谢
【问题讨论】:
不要使用不必要的属性@Column(name = "PK", unique = true, nullable = false)
— @Id
表示它是独一无二的!我不确定nullable = false
,但是对于生成的值,你也不需要它。
感谢您的建议,但即使取出 unique = true 它仍然会抛出相同的异常
不客气。当然,它不能修复错误。这只是一个建议。
你也不需要它@Basic(optional = false)
【参考方案1】:
大家早上好
因此,在经历了很多痛苦和磨难之后,问题的答案如下,在创建表时不要忘记将主键设置为 IDENTITY。谢谢大家的意见。
问候
布赖恩
【讨论】:
【参考方案2】:您将相同的 PK 5 分配给尚未分配 PK 的所有实体。这意味着,您尝试使用完全相同的 PK 值保存所有新实例。
如果您使用生成的 ID,请不要为实体的 PK 字段分配任何内容。
【讨论】:
您好 感谢您抽出宝贵的时间来回答。我把它放进去是为了证明即使一个静态设置了一次,在一个空表上它仍然会抛出一个异常。问题是,即使我把它拿出来,我也会遇到这个理智的问题 然后将 PK 字段设置为可为空。异常谈论未通过的非空检查。您在 Numbers 的 PK 字段中从哪里获得 nullable=false ?它说从 hbm.xml 生成,但你没有改变它吗?还要检查 hbm.xml 或 annotations 哪个优先。 再次感谢您。当我生成 XML 时,我得到了 nullable = false。看到的实体代码是生成的,我一直在尝试更改它以使其正常工作。我所有的其他实体类都具有相同的注释,所以我对此感到非常沮丧。如何确定帽子优先? 尝试搜索您的版本的文档。但我仍然看到 hbm.XML 和您的注释之间存在不一致。您的注释中没有任何生成的 ID 规范。我建议仅使用 hbm.XML 或注释开始。你如何配置休眠?以上是关于Hibernate 和 HSQLDB 违反主键完整性约束的主要内容,如果未能解决你的问题,请参考以下文章
