休眠搜索中用於 ZonedDateTime 的 DateBridge 在索引數據時出現異常

Question

我的實體有一個ZonedDatetime字段

@Indexed
@Entity
public class Book {
    @Id 
    private Long id;
    @Field
    @DateBridge(resolution = Resolution.SECOND)
    private ZonedDateTime createdAt;

    // Other fields and setters & getters
}

當我嘗試保存實體時，應用程序拋出以下異常

    field bridge: TwoWayString2FieldBridgeAdaptor [stringBridge=org.hibernate.search.elasticsearch.bridge.builtin.time.impl.ElasticsearchZonedDateTimeBridge@1bec1730]
        at 

以下是我嘗試過的兩個單元測試，可以重現該問題。

如果我創建一個分區日期時間ZoneId.of("UTC")那么它對彈性搜索橋很好

@Test
public void testObjectToString_withZoneId() {
    Date date = new Date();
    ZonedDateTime zonedDateTime = ZonedDateTime.ofInstant(date.toInstant(), ZoneId.of("UTC"));
    try {
        //this is good
          ElasticsearchZonedDateTimeBridge.INSTANCE.objectToString(zonedDateTime);
    } catch (DateTimeException e) {
        Assert.fail(e.getMessage());
    }
}

但它失敗了下面的代碼

@Test
public void testObjectToString_withZonedOffset() {
    Date date = new Date();
    ZonedDateTime zonedDateTime = ZonedDateTime.ofInstant(date.toInstant(), ZoneOffset.UTC);
    try {
        //this throws exception
          ElasticsearchZonedDateTimeBridge.INSTANCE.objectToString(zonedDateTime);
    } catch (DateTimeException e) {
        // Unable to extract value: class java.time.ZonedDateTime
        Assert.fail(e.getMessage());
    }
}

我使用的休眠版本是，

hibernate-search-elasticsearch, hibernate-search-orm = 5.11.4.Final

這是我的完整堆棧跟蹤

Answer 1

ZoneOffset是ZoneId ，因此此代碼是正確的：

    ZonedDateTime zonedDateTime = ZonedDateTime.ofInstant(date.toInstant(), ZoneOffset.UTC);

但是，在將分區日期時間序列化為 JSON 時，Hibernate Search 使用了一種非常特殊的格式。 該格式要求存在實際區域 ID（不僅僅是偏移量）。

這可以被視為一個錯誤，歡迎您打開一個錯誤報告，但恐怕這不是唯一的問題。 即使在 Search 5 中修復了這個問題，為了成功索引這樣的值，我們仍然需要向后移植HSEARCH-3548的修復程序，據我所知，這需要對 Hibernate 生成的 Elasticsearch 映射進行向后不兼容的更改搜索。 所以我不確定這是否真的可以在 5.11 中修復。

Hibernate Search 5 中的 Elasticsearch 支持是實驗性的。 如果可以，您將有更好的時間升級到 Hibernate Search 6（仍處於測試階段），它為 Elasticsearch 5.6 到 7.x 提供一流的支持，並且實際上對您的特定問題進行了測試（並且它有效）正確）。 但是，Hibernate Search 6 中的 API 是不同的。
