Java org.hibernate.AnnotationException:引用的属性不是（一个|多个）ToOne:

我正在尝试使用Hibernate建立一个OneToOne关系。我试着按照其他问题的建议去做，但我还是遇到了一些问题

我有一个Company类，它有自己的仓库规则集。每个实体都有一个BusinessUnitNumber作为表的Id

我能想到的唯一一件事是，两个表的ID都有相同的列名？但是我不能改变这一点，所以我不知道是否有解决办法（如果确实是这样的话）或者我是否遗漏了什么。

在class

Company

中，您注释了一个字段（

warehouseRules

），但该类中的所有其他人都使用属性。您应该使用属性或字段，但不能混合使用。也许如果你保持一致，你的JPA提供商会明白这一点

---

显然，消息可能更清晰，强调您没有注释属性（getter）。其他JPA提供商不一定坚持使用OneToOne/OneToMany注释，因为从属性/字段类型可以清楚地看出这是一种关系。

我为您提供了一个简单的示例： 人员和地址是一对一的关系。
为此，我使用共享主键关联：
人员类别：

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "person_pk", nullable = false)
private Long personPk;

@OneToOne(cascade = {CascadeType.MERGE, CascadeType.PERSIST})
@PrimaryKeyJoinColumn
private Address address;

地址类别：

@Id
@GeneratedValue(generator = "myForeignGenerator")
@GenericGenerator(name = "myForeignGenerator", 
                    strategy = "foreign", 
                    parameters = @Parameter(name = "property", value = "person"))
@Column(name = "address_pk")
private Long addressPk;

@OneToOne(targetEntity = Person.class)
@PrimaryKeyJoinColumn
private Person person;

要持久化瞬态对象，请执行以下操作：

Person person = new Person();
Address address = new Address();
person.setAddress(address);
address.setPerson(person);

persist(person);

这就是数据库架构的外观：
人员表

person_pk <<PK>>

person\u pk

地址表

address_pk <<PK>><<FK>>

address\u pk

---

按如下方式阅读：保存地址时，主键值取自person属性。person属性是对person对象的引用；因此，插入的主键值与该实例的主键值相同。

您可以共享会话代码吗？太棒了！成功了。我将注释移动到getter，以匹配公司类中的所有其他注释，并且一切都很好。
