休眠 HQL 联接提取不递归提取

我有以下查询和方法

private static final String FIND = "SELECT DISTINCT domain FROM Domain domain LEFT OUTER JOIN FETCH domain.operators LEFT OUTER JOIN FETCH domain.networkCodes WHERE domain.domainId = :domainId";

@Override
public Domain find(Long domainId) {
    Query query = getCurrentSession().createQuery(FIND);
    query.setLong("domainId", domainId);
    return (Domain) query.uniqueResult();
}

与Domain

@Entity
@Table
public class Domain {
    @Id
    @GenericGenerator(name = "generator", strategy = "increment")
    @GeneratedValue(generator = "generator")
    @Column(name = "domain_id")
    private Long domainId;

    @Column(nullable = false, unique = true)
    @NotNull
    private String name;

    @Column(nullable = false)
    @NotNull
    @Enumerated(EnumType.STRING)
    private DomainType type;

    @OneToMany(cascade = {
            CascadeType.PERSIST,
            CascadeType.MERGE
    }, fetch = FetchType.EAGER)
    @JoinTable(joinColumns = {
            @JoinColumn(name = "domain_id")
    }, inverseJoinColumns = {
            @JoinColumn(name = "code")
    })
    @NotEmpty
    @Valid // needed to recur because we specify network codes when creating the domain
    private Set<NetworkCode> networkCodes = new HashSet<>();

    @ManyToMany(fetch = FetchType.EAGER)
    @JoinTable(joinColumns = {
            @JoinColumn(name = "parent", referencedColumnName = "domain_id")
    }, inverseJoinColumns = {
            @JoinColumn(name = "child", referencedColumnName = "domain_id")
    })
    private Set<Domain> operators = new HashSet<>();
    // more
}

我希望这个单个查询能够获取和>关系，但事实并非如此。假设 I 查询有两个运算符，Hibernate 将执行 1 + 2 * 2 = 5 个查询Set<NetworkCode>Set<DomainDomain

Hibernate: select distinct domain0_.domain_id as domain1_1_0_, domain2_.domain_id as domain1_1_1_, networkcod4_.code as code2_2_, domain0_.name as name1_0_, domain0_.type as type1_0_, domain2_.name as name1_1_, domain2_.type as type1_1_, operators1_.parent as parent1_0__, operators1_.child as child4_0__, networkcod3_.domain_id as domain1_1_1__, networkcod3_.code as code5_1__ from domain domain0_ left outer join domain_operators operators1_ on domain0_.domain_id=operators1_.parent left outer join domain domain2_ on operators1_.child=domain2_.domain_id inner join domain_network_codes networkcod3_ on domain0_.domain_id=networkcod3_.domain_id inner join network_code networkcod4_ on networkcod3_.code=networkcod4_.code where domain0_.domain_id=?
Hibernate: select operators0_.parent as parent1_1_, operators0_.child as child4_1_, domain1_.domain_id as domain1_1_0_, domain1_.name as name1_0_, domain1_.type as type1_0_ from domain_operators operators0_ inner join domain domain1_ on operators0_.child=domain1_.domain_id where operators0_.parent=?
Hibernate: select networkcod0_.domain_id as domain1_1_1_, networkcod0_.code as code5_1_, networkcod1_.code as code2_0_ from domain_network_codes networkcod0_ inner join network_code networkcod1_ on networkcod0_.code=networkcod1_.code where networkcod0_.domain_id=?
Hibernate: select operators0_.parent as parent1_1_, operators0_.child as child4_1_, domain1_.domain_id as domain1_1_0_, domain1_.name as name1_0_, domain1_.type as type1_0_ from domain_operators operators0_ inner join domain domain1_ on operators0_.child=domain1_.domain_id where operators0_.parent=?
Hibernate: select networkcod0_.domain_id as domain1_1_1_, networkcod0_.code as code5_1_, networkcod1_.code as code2_0_ from domain_network_codes networkcod0_ inner join network_code networkcod1_ on networkcod0_.code=networkcod1_.code where networkcod0_.domain_id=?

我猜这是因为我正在加入运算符元素，但他们必须自己加入。Domain

是否有我可以执行的 HQL 查询可以同时执行这两项操作？
