java - 個別の SELECT の代わりに Hibernate @Fetch(Join) が適用されない

Question

個別の選択の代わりに JOIN を積極的にロードしたいエンティティへDomainの@ManyToOne一方向の関係を持つエンティティがあります。Countryを使おうと思いまし@Fetchた。

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

    @Fetch(FetchMode.JOIN)
    @ManyToOne(optional = false, fetch = FetchType.EAGER)
    private Country country; 

    ...
}

HQLこれらのエンティティを照会するために使用しています。

しかし、Hibernate はフェッチ戦略を適用しません。私は試してみましたが@OneToOne（私のデザインでは何も変わりません）、それもうまくいきません。SQL 出力の例を次に示します。

Hibernate: select domain0_.domain_id as domain1_2_, domain0_.country as country2_, domain0_.name as name2_, domain0_.type as type2_ from domain domain0_ order by domain0_.name limit ?
Hibernate: select country0_.country_id as country1_1_0_, country0_.code as code1_0_, country0_.currency as currency1_0_, country0_.name as name1_0_ from country country0_ where country0_.country_id=?
Hibernate: select country0_.country_id as country1_1_0_, country0_.code as code1_0_, country0_.currency as currency1_0_, country0_.name as name1_0_ from country country0_ where country0_.country_id=?
Hibernate: select country0_.country_id as country1_1_0_, country0_.code as code1_0_, country0_.currency as currency1_0_, country0_.name as name1_0_ from country country0_ where country0_.country_id=?
Hibernate: select country0_.country_id as country1_1_0_, country0_.code as code1_0_, country0_.currency as currency1_0_, country0_.name as name1_0_ from country country0_ where country0_.country_id=?
Hibernate: select country0_.country_id as country1_1_0_, country0_.code as code1_0_, country0_.currency as currency1_0_, country0_.name as name1_0_ from country country0_ where country0_.country_id=?

何かが適用を妨げていると思います。それは何ですか？
