          "lat" : 32.846027,
          "lon" : -96.84987

推荐答案

您必须添加您的存储库查询的排序参数，请参见描述了Spring Data Elasticsearch 4的文档。

You have to add a Sort parameter t your repository query, see the documentation for Spring Data Elasticsearch 4 where this is described.

在您的情况下，您需要：

In your case you'd need:

Sort sort = Sort.by(
    new GeoDistanceOrder("geoLocation", new GeoPoint(32.846027, -96.84987))
        .withUnit("mi")
        .with(Sort.Direction.ASC)
);

您可以省略排序方向，因为ASC是默认值

you can leave out the sort direction, because ASC is the default value
