java - hibernate 搜索中的 ZonedDateTime 的 DateBridge 在索引数据时出现异常

Question

我的实体有一个 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
}

当我尝试保存实体时，应用程序抛出以下异常

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

这是我尝试过的两个单元测试，可以重现该问题。

如果我创建分区日期时间ZoneId.of("UTC")，那么它适合 Elasticsearch 桥

@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());
    }
}

但它失败并显示以下代码

@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 Hibernate 版本是，

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

这是我的完整堆栈跟踪

Answer 1

ZoneOffset 是 ZoneId，因此此代码是正确的:

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

但是，Hibernate Search 在将分区日期时间序列化为 JSON 时使用非常特定的格式。该格式要求存在实际的区域 ID(而不仅仅是偏移量)。

这可以被视为一个错误，欢迎您打开错误报告，但恐怕这不是唯一的问题。即使这个问题在 Search 5 中得到了修复，为了成功索引这样的值，我们仍然需要反向移植 HSEARCH-3548 的修复程序。 ，据我了解，这需要对 Hibernate Search 生成的 Elasticsearch 映射进行向后不兼容的更改。所以我不确定这是否真的可以在 5.11 中修复。

Hibernate Search 5 中的 Elasticsearch 支持处于实验阶段。如果可以的话，您将有更好的时间升级到 Hibernate Search 6(仍处于测试版)，它为 Elasticsearch 5.6 到 7.x 提供一流的支持，并且实际上对您的特定问题进行了测试(并且它有效)正确)。然而，Hibernate Search 6 中的 API 有所不同。
