我想加入两个模型，都使用org.hibernate.id.UUIDGenerator作为主键。 但是在启动时，出现以下错误：

  

org.hibernate.tool.schema.spi.CommandacceptanceException：错误   执行“ DDL”更改表user_role添加约束   FK5scdquo6f12cpstqai86x4biw外键（roles_role_id）参考   角色（role_id）”通过JDBC语句

你知道吗，我在做错什么？

我的代码：

用户模型：

bsoncxx::value

角色模型：

@Entity
@Table
public class User implements Serializable {

    @Id
    @GeneratedValue(generator = "uuid2")
    @GenericGenerator(name = "uuid2",strategy = "org.hibernate.id.UUIDGenerator")
    @Column(name = "user_id",columnDefinition = "VARCHAR(255)")
    private String userId;

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

    @JoinTable(name = "user_role",joinColumns = @JoinColumn(name = "userId"),inverseJoinColumns = @JoinColumn(name = "roleId"))
    @ManyToMany
    private List<Role> roles;

    public User(){
        this.roles = new ArrayList<>();
    }
// Getter & Setter
}

用户DAO：

@Entity
@Table
public class Role implements Serializable {

    @Id
    @GeneratedValue(generator = "uuid2")
    @GenericGenerator(name = "uuid2",strategy = "org.hibernate.id.UUIDGenerator")
    @Column(name = "role_id",columnDefinition = "VARCHAR(255)")
    private String roleId;

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

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

    @ManyToMany(mappedBy = "roles")
    private List<User> users;

    public Role(){
        this.users = new ArrayList<>();
    }
// Getter & Setter
}

角色DAO：

public interface UserDAO extends JpaRepository<User,String > {
}
