spring数据jpa onetomany到非id列的Map只对一组实体起作用，而对另一组实体则失败

user、role、userroleMap工作正常，但project、salesorder、projectsoMap失败，只有一个例外。我读了很多关于“在Map中使用非pk列”在jpa2.0中是可选的，但我不知道为什么它对用户角色有效，而对projectsalesorder无效。
时间表基

@MappedSuperclass
@Data
@EqualsAndHashCode(callSuper = true)
public class TimesheetBase extends Auditable<String> implements Serializable {
    @Id
    @GeneratedValue
    @Column(name = "id")
    protected Long id;

    @Column(name = "active")
    protected boolean active = true;
}

用户

@Entity
@Table(name = "ts_user")
@Data
@EqualsAndHashCode(callSuper = true)
public class User extends TimesheetBase {
    @Column(name = "user_id", unique = true)
    private String userId;

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

    @OneToMany(mappedBy = "user")
    private Set<UserRole> userRoles;
}

角色

@Entity
@Table(name = "ts_role")
@Data
@EqualsAndHashCode(callSuper = true)
public class Role extends TimesheetBase {
    @Column(name = "role_id", unique = true)
    private String roleId;

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

    @OneToMany(mappedBy = "role")
    private Set<UserRole> userRoles;
}

用户角色

@Entity
@Table(name = "ts_user_role")
@Data
@EqualsAndHashCode(callSuper = true)
public class UserRole extends TimesheetBase {
    @ManyToOne
    @JoinColumn(name = "user_id", referencedColumnName = "user_id")
    private User user;

    @ManyToOne
    @JoinColumn(name = "role_id", referencedColumnName = "role_id")
    private Role role;
}

上面的工作非常好。然而，下面的一个失败了。
项目

@Entity
@Table(name = "ts_project")
@Data
@EqualsAndHashCode(callSuper = true)
public class Project extends TimesheetBase {
    @Column(name = "project_id", unique = true)
    private String projectId;

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

    @OneToMany(mappedBy = "project")
    private Set<ProjectSo> projectSos;
}

销售订单

@Entity
@Table(name = "ts_so")
@Data
@EqualsAndHashCode(callSuper = true)
public class SalesOrder extends TimesheetBase {
    @Column(name = "so_id", unique = true)
    private String soId;

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

    @OneToOne(mappedBy = "salesOrder")
    private ProjectSo projectSo;
}

项目SO

@Entity
@Table(name = "ts_project_so")
@Data
@EqualsAndHashCode(callSuper = true)
public class ProjectSo extends TimesheetBase {
    @ManyToOne
    @JoinColumn(name = "project_id", referencedColumnName = "project_id")
    private Project project;

    @OneToOne
    @JoinColumn(name = "so_id", referencedColumnName = "so_id")
    private SalesOrder salesOrder;
}
