使用orientdb-enterprise-2.2.21和orientdb-community-2.2.21的空间索引问题

Question

我正在尝试通过Java API创建空间索引，我正在使用Orient DB orientdb-enterprise-2.2.21。 使用远程连接运行测试。我试图用几种方法创建类和属性已经创建。

 nodeClass = graph.createVertexType(NODE_CLASS_NAME); 
     nodeClass.createProperty("latitude", OType.DOUBLE); 
     nodeClass.createProperty("longitude", OType.DOUBLE); 
     nodeClass.createProperty("name", OType.STRING); 
     nodeClass.createProperty("color", OType.STRING); 
     nodeClass.createProperty("location", OType.EMBEDDED); 

，结果是：

我在几个方面创造了空间索引，他们都失败：

案例1中的 “老办法”：

nodeClass.createIndex("Group.latitude_longitude", "SPATIAL", null, null, "LUCENE", new String[] { "latitude", "longitude" }); 

结果：

Exception in thread "main" com.orientechnologies.orient.core.index.OIndexException: Index with type SPATIAL and algorithm null does not exist. 
    DB name="demodb" 

情况2：

 graph.command(new OCommandSQL(
     "CREATE INDEX Group.location ON Group(location) SPATIAL ENGINE LUCENE")).execute(); 

结果：

Exception in thread "main" com.orientechnologies.orient.core.index.OIndexException: Index with type SPATIAL and algorithm null does not exist. 
    DB name="demodb" 

情况3：

 OIndex<?> idx = nodeClass.getProperty("location"). 
       createIndex(OClass.INDEX_TYPE.SPATIAL, new ODocument().field("ignoreNullValues", true)); 

结果：

Exception in thread "main" com.orientechnologies.orient.core.index.OIndexException: Index with type SPATIAL and algorithm null does not exist. 
    DB name="demodb"

有没有人有任何建议？遇到与orientdb-community-2.2.21相同的行为。

您是否在服务器上安装了空间插件？
