Java 使用ElasticsearchRestTemplate映射OffsetDateTime

在我的应用程序中，我正在从

TransportClient

切换到

RestHighLevelClient

，它使用

spring data elasticsearch

。当我试图用类型为

OffsetDateTime

的字段保存实体时，我得到以下示例：

Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is ElasticsearchStatusException[Elasticsearch exception [type=mapper_parsing_exception, reason=failed to parse field [createdAt] of type [float]]]; nested: ElasticsearchException[Elasticsearch exception [type=json_parse_exception, reason=Current token (START_OBJECT) not numeric, can not use numeric value accessors
 at [Source: org.elasticsearch.common.bytes.BytesReference$MarkSupportingStreamInputWrapper@2d7d44ce; line: 1, column: 35]]];] with root cause

org.elasticsearch.ElasticsearchException: Elasticsearch exception [type=json_parse_exception, reason=Current token (START_OBJECT) not numeric, can not use numeric value accessors
 at [Source: org.elasticsearch.common.bytes.BytesReference$MarkSupportingStreamInputWrapper@2d7d44ce; line: 1, column: 35]]
    at org.elasticsearch.ElasticsearchException.innerFromXContent(ElasticsearchException.java:509)
    at org.elasticsearch.ElasticsearchException.fromXContent(ElasticsearchException.java:420)
    at org.elasticsearch.ElasticsearchException.innerFromXContent(ElasticsearchException.java:450)
    at org.elasticsearch.ElasticsearchException.failureFromXContent(ElasticsearchException.java:616)
    at org.elasticsearch.rest.BytesRestResponse.errorFromXContent(BytesRestResponse.java:169)
    at org.elasticsearch.client.RestHighLevelClient.parseEntity(RestHighLevelClient.java:2050)
    at org.elasticsearch.client.RestHighLevelClient.parseResponseException(RestHighLevelClient.java:2026)
...

这是我的Elasticsearch配置：

@Bean(destroyMethod = "close")
public RestHighLevelClient client() {
    return new RestHighLevelClient(RestClient.builder(new HttpHost(elasticsearchHost, elasticsearchPort)));
}

@Bean
public ElasticsearchRestTemplate elasticsearchTemplate(RestHighLevelClient client) {
    return new ElasticsearchRestTemplate(client);
}

以下是简化的实体定义：

@Data
public class MyEntity {

    @Field(type = FieldType.Date)
    private OffsetDateTime createdAt;

}

为了能够使用类型为

OffsetDateTime

的字段，我应该配置什么？
