嵌入式实体上的hibernate过滤器

我有一个dropwizard应用程序,它使用hibernate搜索。简而言之,我的数据库里有动物和它们的数据,我试图添加一个过滤器来获取特定品种列表中的动物。不幸的是,我的过滤器似乎不起作用,我不知道为什么。我怀疑这可能是我如何定义实体之间的关系,以及我如何在 FilterFactory ,但在我看来是对的。我已经实现了基于 Hibernate documentation . 相关类别如下:

我的 Animal 班级:

@Entity
@Indexed
@FullTextFilterDef(name = "animalFilter", impl = AnimalFilterFactory.class)
@Table(name = "animal")
@JsonIgnoreProperties(ignoreUnknown = true)
public class Animal implements Serializable{

    @Id
    @Column(name = "id")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @IndexedEmbedded
    @OneToOne(fetch = FetchType.LAZY,
            cascade =  CascadeType.ALL,
            mappedBy = "animal")
    private AnimalInfo info;
// rest of the class goes here
}

我的 AnimalInfo 班级:

@Entity
@Table(name = "animal_info")
@JsonIgnoreProperties(ignoreUnknown = true)
public class AnimalInfo implements Serializable{

    @Id
    @Column(name = "animal_id")
    private Long animalId;

    @IndexedEmbedded
    @ManyToOne( cascade = CascadeType.ALL )
    @JoinColumn(name="breed_id")
    private AnimalBreed breed;
// rest of the class goes here
}

我的 AnimalBreed 班级:

@Entity
@Table(name = "animal_breeds")
@JsonIgnoreProperties(ignoreUnknown = true)
public class AnimalBreed implements Serializable{

    @Id
    @Column(name = "id")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    /**
     * name of the breed which I want to filter my animals on.
     */
    @Field
    @Column(name = "name")
    private String name;

我的过滤类:也许 "info.breed.name" 陈述不正确?

public class AnimalFilterFactory {
    // list of breed names
    private List<String> breeds;

    public void setBreeds(List<String> breeds) {
        this.breeds = breeds;
    }    
    @Factory
    public Query getFilter() {

        BooleanQuery.Builder booleanQuery = new BooleanQuery.Builder();
         // apply filter for all the breeds
        for (String breed : breeds) {
            booleanQuery.add(new TermQuery( new Term( "info.breed.name", breed ) ), Occur.SHOULD);
        }
        return booleanQuery.build();
    }

}

在dao类中,我想应用过滤器:

public List<Animal> getForBreeds(List<String> breedNames){
        EntityManager em = this.currentSession();

        FullTextEntityManager fullTextEntityManager = Search.getFullTextEntityManager(em);

        QueryBuilder qb = fullTextEntityManager.getSearchFactory()
                .buildQueryBuilder()
                .forEntity(Animal.class)
                .get();

        qb.sort().byNative(SortField.FIELD_SCORE).andByNative(new SortField("id", Type.STRING, true));


        org.apache.lucene.search.Query luceneQuery = qb.all().createQuery(); // get all the items 

        // apply filter
        FullTextQuery ftq = fullTextEntityManager.createFullTextQuery(luceneQuery, Animal.class);
        ftq.enableFullTextFilter("animalFilter").setParameter("breeds", breedNames);


        return ftq.getResultList();
}

我已经测试过,如果不应用过滤器,数据库中的所有动物实体都会被返回。所以看来过滤器绝对是问题所在。

如有任何帮助,我们将不胜感激。
