我将我的应用程序从springboot2.2.5升级到了2.3.3，并且我正在使用springdatajpastarter和5.4.20.final。我的实体在编译时得到增强。
现在当我使用 @EntityGraph 注解 attributePaths 覆盖的属性 findAll 方法来自 JpaRepository 我得到一个警告：

2020-08-19 12:13:41.121  WARN 9348 --- [nio-8060-exec-3] [] [] o.h.engine.internal.TwoPhaseLoad         : Entity graph specified is not applicable to the entity [DictionaryLang(id=1601, name=null, lang=null)]. Ignored.
2020-08-19 12:13:41.483  WARN 9348 --- [nio-8060-exec-3] [] [] o.h.engine.internal.TwoPhaseLoad         : Entity graph specified is not applicable to the entity [DictionaryValueLang(id=3051, lang=null, name=null)]. Ignored.

即使这个警告图被正确地获取，我也只能在日志中看到一个sql查询，并且应用程序的行为与更新之前一样。
以下是我的存储库代码：

public interface DictionaryRepository extends JpaRepository<Dictionary, Long>, QuerydslPredicateExecutor<Dictionary> {

    @EntityGraph(attributePaths = {"langs", "values", "values.langs"})
    @Override
    Page<Dictionary> findAll(Predicate predicate, Pageable pageable);
}

以下是我的实体：

@Entity
@Table(name = "DICTIONARIES")
public class Dictionary {

    @Id
    @SequenceGenerator(name = "SEQ_DICTIONARIES", sequenceName = "SEQ_DICTIONARIES")
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "SEQ_DICTIONARIES")
    private Long id;

    @OrderBy("ordinal ASC")
    @OneToMany(mappedBy = "dictionary", fetch = FetchType.LAZY, cascade = CascadeType.ALL, orphanRemoval = true)
    private List<DictionaryValue> values;

    @OneToMany(mappedBy = "dictionary", fetch = FetchType.LAZY, cascade = CascadeType.ALL, orphanRemoval = true)
    private Set<DictionaryLang> langs;

}

@Entity
@Table(name = "DICTIONARY_LANGS")
public class DictionaryLang extends BaseEntity {

    @Id
    @SequenceGenerator(name = "SEQ_DICTIONARY_LANGS", sequenceName = "SEQ_DICTIONARY_LANGS")
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "SEQ_DICTIONARY_LANGS")
    private Long id;

    @ManyToOne(fetch = FetchType.LAZY)
    @LazyToOne(LazyToOneOption.PROXY)
    @JoinColumn(name = "DICTIONARY_ID")
    private Dictionary dictionary;

}

如何解决此警告？我可以看到这个警告发生在hibernate的 TwoPhaseLoad 班级：

GraphImplementor fetchGraphContext = session.getFetchGraphLoadContext();
if ( fetchGraphContext != null && !fetchGraphContext.appliesTo( entity.getClass() ) ) {
    LOG.warnf( "Entity graph specified is not applicable to the entity [%s]. Ignored.", entity);
    fetchGraphContext = null;
    session.setFetchGraphLoadContext( null );
}
