如何使用org.springframework.data.geo.point

Question

我需要在Redis中存储纬度和经度。然后，我需要获取半径5公里以下的所有地理位置。为此，我使用下面的代码。

@Autowired
RedisTemplate redisTemplate;

GeoOperations<String, String> geoOperations;

@GetMapping("/test")
public ResponseEntity<Object> demoMethod(@RequestParam("distance") int distance) {
    geoOperations=redisTemplate.opsForGeo();
    geoOperations.add("Sicily", new Point(6.986786, 81.057408), "Dewala Veediya");
    geoOperations.add("Sicily", new Point(6.984505, 81.058229), "Bank Road");
    geoOperations.add("Sicily", new Point(6.990438, 81.056829), "Palermo");
    geoOperations.add("Sicily", new Point(6.990703, 81.052492), "Vishaka");
    geoOperations.add("Sicily", new Point(6.990703, 81.052492), "Vishaka");
    geoOperations.add("Sicily", new Point(6.955504, 81.031509), "Haliela");
    geoOperations.add("Sicily", new Point(6.931982, 79.846692), "colombo");
    Circle circle = new Circle(new Point(6.990438, 81.056829),new Distance(distance, DistanceUnit.KILOMETERS));
    GeoResults<GeoLocation<String>> result = geoOperations.radius("Sicily", circle);

    return sendResponse(result);
}

响应为

{
"averageDistance": {
    "value": 0,
    "metric": "NEUTRAL"
},
"content": [
    {
        "content": {
            "name": "Haliela",
            "point": null
        },
        "distance": {
            "value": 0,
            "metric": "NEUTRAL"
        }
    },
    {
        "content": {
            "name": "Bank Road",
            "point": null
        },
        "distance": {
            "value": 0,
            "metric": "NEUTRAL"
        }
    },
    {
        "content": {
            "name": "Dewala Veediya",
            "point": null
        },
        "distance": {
            "value": 0,
            "metric": "NEUTRAL"
        }
    },
    {
        "content": {
            "name": "Vishaka",
            "point": null
        },
        "distance": {
            "value": 0,
            "metric": "NEUTRAL"
        }
    },
    {
        "content": {
            "name": "Palermo",
            "point": null
        },
        "distance": {
            "value": 0,
            "metric": "NEUTRAL"
        }
        }
    ]
}

  

我将经度和纬度分别作为X和Y点。为什么距离和点的值等于0。
