spring 中使用 redis 搜索附近位置总是返回为空

[hunk]

Spring 加载时从数据库读取数据写入 redis ，使用命令行可以返回结果 geosearch project:locs fromlonlat 112.xx 32.xx BYRADIUS 200 km WITHDIST ASC

1. 1. "9"
2. "1.3747"
3. 1. "11"
   2. "2.2997"
4. 1. "10"
   2. "2.4876"

但在程序中始终结果为 0 ，请帮忙分析下是什么原因？

    String key = "project:locs";

    GeoResults<RedisGeoCommands.GeoLocation<String>> results = redisTemplate.opsForGeo().search(
            key,
            GeoReference.fromCoordinate(112.xx,32.xx),
            new Distance(5000000, Metrics.KILOMETERS),
            RedisGeoCommands.GeoSearchCommandArgs.newGeoSearchArgs().includeDistance().limit(100));

    List<GeoResult<RedisGeoCommands.GeoLocation<String>>> content = results.getContent();
