Elasticsearch：在 QueryBuilders.termsQuery() 中添加 arraylist 会引发错误答案

【问题描述】：

我正在尝试将值列表传递给QueryBuilders.termsQuery()，但它抛出了错误：

抑制：org.elasticsearch.client.ResponseException：方法 [GET]，主机 [http://localhost:9200], URI [/replacement/_search?typed_keys=true&ignore_unavailable=false&expand_wildcards=open&allow_no_indices=true&search_type=query_then_fetch&batched_reduce_size=512], 状态行 [HTTP/1.1 400 错误请求]

这是我的java代码：

Replacement linkId = null;
Replacement replacement = null;
List<Replacement> linkIDList=new ArrayList<Replacement>();
for (SearchHit hit1 : searchHits1) {
    linkId = new Replacement();
     Map<String, Object> sourceAsMap1 = hit1.getSourceAsMap();
     linkId.setLink_id((Integer) sourceAsMap1.get("link_id"));
     linkIDList.add(linkId);
}

QueryBuilder qb2 = QueryBuilders.termsQuery("id",linkIDList); // this line throws error

这段代码有什么问题？

请找到完整的堆栈跟踪

【问题讨论】：

请打印完整的堆栈跟踪。在此之后必须有剩余的错误跟踪
@Richa - 我已经更新了完整的堆栈跟踪。

标签： java elasticsearch collections elastic-stack elasticsearch-java-api

【解决方案1】：

如堆栈跟踪所示，这是因为Number Format Exception。您需要发送Integer 的列表，这是id 字段的类型，而不是像您的代码中提到的那样传递List<Replacement>。

创建一个 List 并传递该列表，而不是创建 List<Replacement> 的对象。

希望它对你有用。
