@IndexedEmbedded 在包含其他 @IndexedEmbedded 字段的类上

Question

我正在尝试管理一个类的休眠搜索索引，该类的字段由@IndexedEmbedded 在自定义@Embeddable 实体上映射。该实体还包含@MappedSuperclass 中的其他@IndexedEmbedded 字段。 这些是涉及的实体：

@Builder
@Entity
@Getter
@Setter
@NoArgsConstructor
@AllArgsConstructor
@ToString
@Indexed
@GeoPointBinding(fieldName = "location") 
public class Insertion {

    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "INSERTION_SEQ")
    private Long id;

    @NotNull
    @GenericField
    private Boolean publicated;

    @NotNull
    @Latitude
    private Double latitude;

    @NotNull
    @Longitude
    private Double longitude;

    @JsonIgnore
    private Point location;

    @FullTextField(analyzer = "generic_text")
    @KeywordField(name="city_sort", sortable = Sortable.YES, normalizer = "sort")
    private String city;

    @NotNull
    @Embedded
    @Valid
    @IndexedEmbedded
    private Amount amount;
    
    @IndexedEmbedded(name = "insertion_mate_preferences")
    @Embedded
    @Valid
    private MatePreference matePreferences;

}

还有这些类：

@SuperBuilder
@Getter
@Setter
@NoArgsConstructor
@AllArgsConstructor
@Embeddable
public class MatePreference extends BaseProfile {
    
    @NotNull
    @GenericField
    private Integer minAge;
    
    @NotNull
    @GenericField
    private Integer maxAge;
    
}

@Getter
@Setter
@NoArgsConstructor
@AllArgsConstructor
@SuperBuilder
@MappedSuperclass
public abstract class BaseProfile implements BaseProfileView {

    @GenericField
    private Boolean smoker;

    @GenericField
    private Boolean children;

    @GenericField
    private Boolean hasAnimals;

    @GenericField
    private Boolean student;

    @GenericField
    private Boolean employed;
    
    @GenericField
    private String animalsDescription;
    
    @Enumerated(EnumType.STRING)
    @GenericField
    private Genre genre;
    
    @Enumerated(EnumType.STRING)
    @GenericField
    private OccupationSector occupation;
    
    @Enumerated(EnumType.STRING)
    @ElementCollection(fetch = FetchType.EAGER)
    @GenericField
    @IndexedEmbedded
    private Set<Personality> personalities;

    @Enumerated(EnumType.STRING)
    @ElementCollection(fetch = FetchType.EAGER)
    @GenericField
    @IndexedEmbedded
    private Set<Lifestyle> lifestyles;
    
    @ElementCollection(fetch = FetchType.EAGER)
    @GenericField
    @IndexedEmbedded
    private Set<Language> languages;
    
    @Enumerated(EnumType.STRING)
    @GenericField
    private StudyTitle titleOfStudy;
    
    @Enumerated(EnumType.STRING)
    @GenericField
    private StudyField studyField;
}

运行应用程序时，Hibernate Search 会抛出以下错误：

我使用以下依赖项运行它：

关于如何管理这种情况有什么建议吗？

Answer 1

此代码不正确：

    @GenericField
    @IndexedEmbedded
    private Set<Language> languages;

使用@GenericField，您要求Hibernate Search 为语言生成一个“值”字段（字符串、整数等）。这通常不起作用，因为 Hibernate Search 不知道如何将 Language 转换为字符串/整数/...，所以这是第一个问题。

但是第二个问题，也是 Hibernate Search 报告的问题，是通过将@IndexedEmbedded 放在同一个属性上，您还要求 Hibernate Search 生成一个“对象”（复合）字段，与@GenericField 中的“值”字段同名。所以有一个冲突：“值”字段和“对象”字段都具有相同的名称，“语言”。

您应该在使用@IndexedEmbedded 的任何地方删除@GenericField。

---

请注意，从技术上讲，您可以在同一属性上同时使用 @GenericField 和 @IndexedEmbedded，只要您使用 @GenericField(name = ...) 或 @IndexedEmbedded(name = ...) 在任一注释上明确设置不同的名称.但是除非您使用custom value bridge，否则@GenericField 将无法工作，而且我认为您的意图并不是要这样做。所以请不要这样做，除非你有真正的原因并且@IndexedEmbedded 没有做你想做的事。
