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

我试图通过使用orientdb-orientdb-enterprise-2.2.21的JavaAPI创建一个空间索引。使用远程连接运行测试。我尝试使用几种方法创建类，并创建了属性

        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：

我用几种方法创建空间索引，但都失败了：

案例1“老办法”：

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"

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

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

案例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"

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

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

案例3：

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

有人有什么建议吗？orientdb-community-2.2.21遇到了相同的行为。

您是否在服务器上安装了spatial插件

感谢您的反馈，确实有所帮助。但是，我必须使用嵌入式SQL创建属性和索引才能使其工作。这是它工作的唯一方式：OCommandRequest commandRequest=graph.command（新的OCommandSQL（“在组（位置）空间引擎LUCENE上创建索引组.location”）；为了清楚起见，我首先需要->（1）graph.command（新的OCommandSQL（“CREATE PROPERTY Group.location EMBEDDED OPoint”）.execute（）；然后->（2）OCommandRequest commandRequest=graph.command（新的OCommandSQL（“在组（位置）空间引擎LUCENE上创建索引组.location”）；要从Java执行此操作似乎有点尴尬。感谢您提供的信息。
