Question

为什么Hibernate不正确地绑定我的值参数？如对unresolved HHH-8020 issue的评论，当Hibernate 5.3.1的定义是以连接的HHH000346命名时，SQLState: 22023仍然给我一个错误（@JoinTable，@Entity）本身（恰好有一个复合@EmbeddedId，其中一个属性在@JoinColumn(name="ref_name")和joinColumns={..}中都被称为inverseJoinColumns={..}）：

@Embeddable
public class MyCompositeId
{ 
    @Column(name = "ref_name") 
    private String name; 

    @Column(name = "partial_id") 
    private Integer id; 

    @Column(name = "extension_id") 
    private String extensionId; 
}

interface MyLinkedEntity { }

@Entity
@Table(name = "my_join_table")
class MyLinkedEntityImpl implements MyLinkedEntity
{ 
    @EmbeddedId 
    private MyCompositeId id; 

    @Column(name = "extension_value") 
    private byte[] extensionValue; 
}

@Entity
class MyEntry {

    @Id
    @Column(name = "name")
    private String name;

    @OneToMany(fetch = FetchType.EAGER, targetEntity = MyLinkedEntityImpl.class, cascade = CascadeType.ALL)
    @JoinTable(name = "my_join_table", 
        joinColumns = @JoinColumn(name = "ref_name", insertable = false, updatable = false),
        inverseJoinColumns = { 
            @JoinColumn(name = "extension_id", referencedColumnName = "extension_id"), 
            @JoinColumn(name = "partial_name", referencedColumnName = "partial_name"), 
            @JoinColumn(name = "ref_name", referencedColumnName = "ref_name"), 
        })
    private Set<MyLinkedEntity> linkedEntities = new HashSet<>();
}

我的日志显示MyLinkedEntity首先被完全保留（冗余），然后再次是关系映射（即没有extension_value列）和{{1}的重复/错误值绑定}（相反）联接列：

ref_name

带有堆栈跟踪代码段：
