我正在使用 Elastic 的 Java 高级 REST 客户端从 Java 中搜索弹性搜索索引。
我的回复看起来像这样...

如何解析出每个文档命中的纬度和经度?纬度和经度存储在 GeoPoint 类型的名为“位置”的字段中
这是我尝试过的...
SearchHit[] hits = searchResponse.getHits().getHits();
for (SearchHit hit : hits) {
Map<String, Object> contactMap = hit.getSourceAsMap();
LinkedHashMap<String, Object> contactLHM = new LinkedHashMap<>(contactMap);
Object coordinate = contactLHM.get("location");
location.latitude = ??????
location.longitude = ?????
}
鉴于坐标变量的值是,我如何解析纬度和经度
{lon=-71.34, 纬度=41.12}
顺便说一下,这是位置类定义:
public static class Location{
public Double latitude;
public Double longitude;
}
