elasticsearch - java.lang.IllegalArgumentException : cannot write xcontent for unknown value of type class java. util.UUID？

Question

嗨，我正在使用 java 高级 rest api 客户端从 Elasticsearch 索引中读取一些文档，但出现以下错误。

当我在 elasticsearch 客户端上执行请求时出现此错误，如下所示。

elasticSearchClient.search(searchRequest, RequestOptions.DEFAULT);

知道这个错误的原因是什么。
我正在使用 Elasticsearch java rest 客户端 api 版本 6.6.1

非常感谢任何帮助
谢谢你

Answer 1

我已经使用 toString() 来解决这个问题， messageHistoryFilterRequest.getAccountId() 正在返回一个 java.util.UUID 。 Elasticsearch 不理解 UUID 。所以一旦我做了一个 toString() 就解决了

if (messageHistoryFilterRequest.getAccountId() != null) {
    MatchQueryBuilder matchQueryBuilder = new MatchQueryBuilder("account_id",
            messageHistoryFilterRequest.getAccountId().toString());
    boolQueryBuilder.must(matchQueryBuilder);
}

if (messageHistoryFilterRequest.getCampaignId() != null) {
    MatchQueryBuilder matchQueryBuilder = new MatchQueryBuilder("campaign_id",
            messageHistoryFilterRequest.getCampaignId().toString());
    boolQueryBuilder.must(matchQueryBuilder);
}

if (messageHistoryFilterRequest.getFlightId() != null) {
    MatchQueryBuilder matchQueryBuilder = new MatchQueryBuilder("flight_id",
            messageHistoryFilterRequest.getFlightId().toString());
    boolQueryBuilder.must(matchQueryBuilder);
}
