Hibernate 搜索@IndexedEmbedded

我有类似的情况这个

@Entity
@Indexed
public class Place {
    @Id
    @GeneratedValue
    @DocumentId
    private Long id;

    @Field( index = Index.TOKENIZED )
    private String name;

    @OneToOne( cascade = { CascadeType.PERSIST, CascadeType.REMOVE } )
    @IndexedEmbedded
    private Address address;
    ....
}

@Entity
public class Address {
    @Id
    @GeneratedValue
    private Long id;

    @Field(index=Index.TOKENIZED)
    private String street;

    @Field(index=Index.TOKENIZED)
    private String city;

    @ContainedIn
    @OneToMany(mappedBy="address")
    private Set<Place> places;
    ...
}

现在的问题如下：例如，如果我更改实体 Place 中的 name 字段，哪些实体将被重新索引？

1) 只有名称字段？

2) 整个Place实体？

3) 整个Place实体和用@IndexedEmbedded注释的实体？

我需要的就是第三个。那么如果它不是标准的，是否有任何解决方案可以实现这种行为？

I have a similar situation like this one

@Entity
@Indexed
public class Place {
    @Id
    @GeneratedValue
    @DocumentId
    private Long id;

    @Field( index = Index.TOKENIZED )
    private String name;

    @OneToOne( cascade = { CascadeType.PERSIST, CascadeType.REMOVE } )
    @IndexedEmbedded
    private Address address;
    ....
}

@Entity
public class Address {
    @Id
    @GeneratedValue
    private Long id;

    @Field(index=Index.TOKENIZED)
    private String street;

    @Field(index=Index.TOKENIZED)
    private String city;

    @ContainedIn
    @OneToMany(mappedBy="address")
    private Set<Place> places;
    ...
}

The problem now is the following:
If I change for example the name field in entity Place which entities are going to be re-indexed?

1) Only the name field?

2) The whole Place entity?

3) The whole Place entity and the entities annotated with @IndexedEmbedded?

The one I need for my purpose would be the third. So if it is not standard, could there be any solution to achieve this behaviour?

幸运的是，这确实是第三个，所以我很幸运，它按预期工作

您可以使用以下代码手动重新索引 Place 实体

public void updateIndex(T entity){
        FullTextEntityManager fullTextEntityManager = Search.getFullTextEntityManager(em);
        fullTextEntityManager.index(entity);
        fullTextEntityManager.getSearchFactory().optimize(entity.getClass());
    }

其次，如果您使用 hibernate，您可以在 persistence.xml 中配置 lucene 以自动更新已更改实体的索引

You can use the following code to re-index the Place Entity manually

public void updateIndex(T entity){
        FullTextEntityManager fullTextEntityManager = Search.getFullTextEntityManager(em);
        fullTextEntityManager.index(entity);
        fullTextEntityManager.getSearchFactory().optimize(entity.getClass());
    }

Secondly if you are using hibernate you can configure lucene in persistence.xml to automatically update the indexes of the entities that are changed
