java - Elasticsearch:在 QueryBuilders.termsQuery() 中添加 arraylist 会抛出错误

Question

我试图将值列表传递给 QueryBuilders.termsQuery()，但它抛出了错误:

Suppressed: org.elasticsearch.client.ResponseException: method [GET], host [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], status line [HTTP/1.1 400 Bad Request]

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

Answer 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 的类型字段而不是传递 List<Replacement>如您的代码中所述。

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

希望它对你有用。
