Java Hibernate JoinTable错误：找不到具有逻辑名称的列

我正在尝试通过hibernate中的JoinTable进行单向多通关联，但我一直遇到以下错误：

A JPA error occurred (Unable to build EntityManagerFactory): Unable to find column with logical name: name in org.hibernate.mapping.Table(users) and its related supertables and secondary tables

我有3个模型房屋，用户，用户房屋地图。我希望能够通过UserHouseMap访问用户住宅。这是用户的映射

出于其他原因，我需要通过不是主键的列将用户映射到UserHouseMap

@Id
@GeneratedValue
@Expose
public Long id;

@Expose
@Required
@ManyToOne
@JoinTable(name = "user_house_map",
        joinColumns= {@JoinColumn(table="users", name="user_name", referencedColumnName="name")},
        inverseJoinColumns={@JoinColumn(table="houses", name="house_name", referencedColumnName="house_name")})
public House house;

以下是所有3个模型的DB模式

使用者

房屋

用户房屋地图

从JoinColumn注释中删除table=用户和table=房屋

此属性不应包含外键的目标表。它仅在一个实体映射到两个表时使用，以便判断联接列位于哪个表中

此外，您的表定义非常奇怪：

join表应该有两个外键：一个引用users表的PK，另一个引用house表的PK。为什么引用用户的名称而不是其ID？ users.name上的外键约束没有意义。

我认为这是因为您将用户pkey定义为id，并试图将其与user_name连接，因此错误bigint=character variaging请尝试从id字段中删除注释@id，然后查看结果happens@JorgeCampos您是对的，所以我将映射更改为使用referenceColumn。检查我的更新错误
