当我使用@Id 在实体上定义字段时，我似乎遇到了麻烦，并且还有一个与字段名称不匹配的@Column 注释。IE

public class MyEntity {
    @Id
    @Column(name = "foo")
    private Long id;

   ...   
}

当我尝试使用存储库 save() 方法持久保存它时，我得到：

org.springframework.beans.factory.BeanCreationExeption
org.springframework.dao.DataIntegrityViolationException
Integrity constraint violation: 
    NOT Null check constraint; SYS_CT_10083 table: MyEntity column ID

如果 @Column 注释中的名称更改为“id”（以匹配字段名称和 getId() 访问器），则它可以完美运行。

这发生在一个测试中，我从我的实体创建了一个嵌入式 H2 或 HSQL 数据库（我都尝试过）。

通过挖掘日志，我可以看到该表的创建不正确：

[tool.hbm2ddl.SchemaUpdate] 
create table MyEntity (
    foo bigint not null, 
    ..., 
    id integer not null, 
    primary key (id))

因此，问题似乎在于存在 @Id 注释时如何生成表。

有人对我应该在哪里解决这个问题有任何想法吗？在我看来，spring data 或 hibernate 中可能存在错误，但我不太确定如何最好地解决这个问题。

仅供参考 - 我正在使用 Spring 3.2.4.RELEASE、spring-data-jpa 1.3.4.RELEASE 和 hibernate-entitymanager 4.0.1.Final

对于那些喜欢阅读堆栈跟踪的人，下面是一个完整的跟踪示例。

感谢任何人都可以提供的任何帮助！

在大大简化了应用程序之后，我确定这个异常是有 2 个实体引用同一个表的副作用，其中第二个表确实有一个名为“id”的字段。

IE

@Entity
@Table(name = "my_table")
public class MyEntity {
    @Id @Column(name = "pk") private Long id;
    ...
}

@Entity
@Table(name = "my_table")
public class MyOtherEntity {
    @Id @Column(name = "id") private Long id;
    ...
}

在我看来，这似乎导致 Hibernate/JPA 生成并验证由两个实体组合而成的表，其中（在上面的示例中）“pk”和“id”都是非空字段，并且（可能是因为按字母顺序较晚）主键设置为 MyOtherEntity 的@Id。

我不确定这是否是设计使然。当然，我可以看到有多个小实体引用一个巨大的平面表，这在使用“遗留”数据库时可能很有用。但这确实让我感到震惊。尤其是它处理 2 个单独的 @Id 字段（均非空，但只有一个主键）的方式。

通常使用生成器为 id 列创建值。

尝试：

@Entity
public class MyEntity {
    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name = "foo")
    private Long id;

   ...   
}
