Java Spring数据弹性搜索-按距离对地理位置排序

给定一个地理位置点，我试图找到10公里内的一些地点，并按离给定位置最近的地点进行排序

我设法返回了10公里范围内的位置列表，但当我尝试对其进行排序时，出现了异常：

我正在使用以下版本的：

<properties>
        <commonscollections>3.2.1</commonscollections>
        <commonslang>2.6</commonslang>
        <spring.data.elasticsearch>1.0.0.BUILD-SNAPSHOT</spring.data.elasticsearch>
        <springversion>3.2.5.RELEASE</springversion>
</properties>

然后代码将返回所有位置，问题在于排序

我从elasticsearch日志中获得的错误：

如果有人告诉我是否有可能按离我最近的位置排序，我非常感谢

提前非常感谢

以防其他人遇到同样的问题，我们已通过以下方式解决了排序问题：

public List<SiteResource> findByGeoLocation(Double longitude, Double latitude, String channelKey, Double distance) {

        if(StringUtils.isEmpty(distance)){
            distance = defaultRadius;           
        }

        GeoDistanceFilterBuilder filter = FilterBuilders.geoDistanceFilter("location").point(latitude, longitude).distance(distance, DistanceUnit.KILOMETERS);

        SearchQuery searchQuery = new NativeSearchQueryBuilder()
                .withFilter(filter)
                .withSort(SortBuilders.geoDistanceSort("site.location").point(latitude, longitude).order(SortOrder.ASC)).build();

        searchQuery.addIndices(channelKey);
        searchQuery.addTypes("site");

        List<SiteResource> sites = esTemplate.queryForList(searchQuery, com.company.domain.site.SiteResource.class);
        return sites;
    }

公共列表findByGeoLocation（双经度、双纬度、字符串通道键、双距离）{
if（StringUtils.isEmpty（距离））{
距离=默认半径；
}
GeodistanceFilterBuilderFilter=FilterBuilders.geoDistanceFilter（“位置”）。点（纬度、经度）。距离（距离、距离单位。公里）；
SearchQuery SearchQuery=new NativeSearchQueryBuilder（）
.带过滤器（过滤器）
.withSort（SortBuilders.geoDistanceSort（“site.location”）.point（纬度、经度）.order（SortOrder.ASC））.build（）；
searchQuery.additions（channelKey）；
searchQuery.addTypes（“站点”）；
List sites=esTemplate.queryForList（searchQuery，com.company.domain.site.SiteResource.class）；
返回站点；
}

希望它能帮助别人；）

来自@justMe的答案有助于找到实现地理距离搜索的最新可能性。 随着过滤器和查询的合并，我们可以使用QueryBuilder

这就是我获得结果的方式（排序和分页）：

公共列表findByGeoLocationSorted（双纬度、双经度、，
双距离、字符串排序、可分页（可分页）{
GeoDistanceQueryBuilder过滤器=QueryBuilders.geoDistanceQuery（“地理点”）
.点（纬度、经度）。距离（距离、距离单位。公里）；
SearchQuery SearchQuery=new NativeSearchQueryBuilder（）
.withQuery（筛选器）.withPageable（可分页）
.with排序（SortBuilders.geoDistanceSort（“地理点”、纬度、经度）。顺序(
SortOrder.fromString（sort））.build（）；
页面=elasticsearchRestTemplate
.QueryFormage（searchQuery，EsEntity.class）；
if（page.hasContent（））{
返回page.getContent（）；
}
返回集合。emptyList（）；
}

“geoPoint”->elasticsearch实体中的geoPoint字段。

游戏进行得很晚，但自从上周发布的Spring Data elasticsearch 4.0以来，有一个选项可以为

排序定义
地理距离顺序，该排序可以传递到存储库方法

搜索结果中的距离值可以从返回的
SearchHit
对象中读取

我详细介绍了如何做到这一点
您不需要定义elasticsearch版本，因为它将作为spring data elasticsearch的暂时依赖项。您说得对，我刚刚从问题Pj中删除了它，那篇文章看起来很棒，让我试试：）
