Java 可嵌入密钥上的一元映射

我正在尝试为用户（存储在表

用户

中）访问项目（存储在表

选项卡

中）建立权限规则。是否查看某些内容的可用性存储在

权限选项卡中

结果应与语句运行时一样（对于id=2的用户）：

我试图通过
@OneToMany
注释执行此操作，但失败-我收到消息：

部署失败。消息是：异常描述：异常
@从
实体类[类]
com.jtsmr.scheduler.persistence.entities.UsersEntity]不完整。
当源实体类使用复合主键时
@必须使用
@连接列。name和referencedColumnName元素都必须
在每一列中指定

在修改数据库和添加
权限选项卡
之前，一切都正常。当我添加它时，我无法编写正确的
@OneToMany
注释，也无法成功地找到我的案例手册

如果不可能，通过JPQL的解决方案就足够了（我无法构造连接操作）

以下是我的设置：

DB（易于理解的创建语句）：

JPA映射如下（省略函数）：


选项卡：

用户：

@Entity
@Table(name = "users")
public class UsersEntity implements Serializable {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "user_id")
    private Long userId;
    @Column(name = "username")
    private String username;
    @Column(name = "password")
    private String password;
    @Column(name = "name")
    private String name;
    @Column(name = "email")
    private String email;
    @OneToMany
    @JoinTable(
        name = "permissions_tabs",
        joinColumns
        = {
            @JoinColumn(name = "user_id", referencedColumnName = "user_id")},
        inverseJoinColumns
        = {
            @JoinColumn(name = "tab_id", referencedColumnName = "tab_id")})
    private List<PermissionsTabsEntity> allowedTabs;
}

以及许可证：

@Entity
@Table(name = "permissions_tabs")
public class PermissionsTabsEntity implements Serializable {
    @EmbeddedId
    private PermissionsTabsPK id;
    @Column(name = "to_view")
    private boolean toView;
    @Column(name = "to_edit")
    private boolean toEdit;
}

提前谢谢你
