Neo4j空間問題：findWithinDistance：ava.lang.IllegalArgumentException：具有相同名稱但存在不同配置的索引

由於在定義的半徑距離中的地理位置，我們需要定位一組對象。Neo4j空間問題：findWithinDistance：ava.lang.IllegalArgumentException：具有相同名稱但存在不同配置的索引

我們嘗試使用SpatialRepository類實現方法「findWithinDistance」

波紋管用於與指數型點implemntation存儲對象的經度和緯度所使用的代碼中使用Neo4Ĵ空間庫：

@NodeEntity 
@TypeAlias(value="MyObject") 
public class MyObject{ 


    @GraphId Long nodeId; 
    private String label; 
    private String description; 
    private Double lat; 
    private Double lon; 

    @Indexed(indexType = IndexType.POINT, indexName = "locations") 
    String wkt; 

    public void setLocation(float longitude, float latitude) { 
      this.wkt = String.format("POINT(%.2f %.2f)",longitude,longitude); 
    }

1）第一次運行，我們沒有任何問題創造的Neo4j數據庫（我們可以看到，在Neo4j的正確的數據對象）對象爲第二次運行或新對象的創建我們已經說過：具有相同名稱但存在不同配置的索引！

的另一點，我必須實現findWithinDistance方法：我們應該使模板方法或Neo4j的Cypher支架查詢來搜索對象？

感謝你的幫助，

，如果你需要精度

這是您的使用空間索引唯一一類？你是否總是設置indexName值？ Neo4J是嵌入式還是針對遠程服務器運行，並且是否包含/安裝了空間庫？ – JohnMark13 2014-10-31 12:11:15

你怎麼跑這不要猶豫？

您是否可能首先運行「純查詢」變體，導致索引被創建爲lucene索引而不是空間索引？

您也可以刪除與Neo4j的模板索引（你可能要註釋掉該修復程序運行註釋）
