Springframework数据弹性搜索无法创建java.time.ZonedDateTime类的对象

Question

我正在使用推荐的 RestHightCLient 和 ElasticsearchRestTemplate。我正在尝试从弹性搜索中检索ZonedDateTime，但似乎spring-data-elasticsearch无法创建ZonedDateTime类的对象。下面的代码片段有任何问题，我需要添加哪些其他配置。

此外，如果我要直接使用ResHighLevel客户端，而不使用Elasticsearch ch的操作，我需要做什么。

    @Bean
    @Override
    public RestHighLevelClient elasticsearchClient() {
        HttpHeaders httpHeaders = new HttpHeaders();
        httpHeaders.add("content-type", "application/json");
        ClientConfiguration clientConfiguration = ClientConfiguration
                .builder()
                .connectedTo("localhost:9200")
                .build();
        return RestClients.create(clientConfiguration).rest();
    }

    @Bean(name = {"elasticsearchTemplate"})
    public ElasticsearchOperations elasticsearhTemplate() {
        return new ElasticsearchRestTemplate(elasticsearchClient());
    }

Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.data.elasticsearch.core.convert.ConversionException: could not create object of class java.time.ZonedDateTime] with root cause

java.time.DateTimeException: Unable to obtain LocalDate from TemporalAccessor: {YearOfEra=2020, DayOfMonth=25, OffsetSeconds=3600, MonthOfYear=8},ISO resolved to 16:46:47.891 of type java.time.format.Parsed

    @Field(type = FieldType.Date, format = DateFormat.custom, pattern = "yyyy-MM-dd'T'HH:mm:ss.SSS Z")
    private ZonedDateTime created = ZonedDateTime.now();
}

请更改您的模式，使用uuuu而不是yyyy这里记录了Elasticsearch对此负责的更改:https://www . elastic . co/guide/en/elastic search/reference/current/migrate-to-Java-time . html # Java-time-migration-incompatible-date-formats

顺便说一句，你不需要

httpHeaders.add("content-type", "application/json");

Spring Data Elasticsearch不需要@Json…注释。
