我是 neo4j 的新手，并试图将 .osm 数据导入到我的 embeddedDatabase 但它不起作用。我搜索了一些示例代码，最后我通过尝试理解 TestOSMImport.java 得到了这段代码

private void importOSM(){


    OSMImporter importer = new OSMImporter("map2.osm");
    importer.setCharset(Charset.forName("UTF-8"));

    try{
        System.out.println("Bis hier");
        GraphDatabaseService db = new GraphDatabaseFactory().newEmbeddedDatabase(DB_PATH);

        importer.importFile(db, "map2.osm",false,5000,true);

        System.out.println("start____ReIndex!");
        importer.reIndex(db,10000);
        db.shutdown();


    }catch(Exception e){
        System.out.println("__________Import Error!! "+e.getMessage());
        e.printStackTrace();
    }
}

代码正在启动 reIndex 方法，然后出现此错误

有人可以帮我找到解决方案吗？

我将 maven 用于 neo4j 和 -spatial

谢谢你的回复你是对的，我正在使用 neo4j 1.9.4 这是我的 pom.xml

您必须使用neo4-spatial为您正在使用的 Neo4j 版本构建的版本。尝试改变

<version>0.12-neo4j-2.0.0-SNAPSHOT</version>

到

<version>0.11-neo4j-1.9</version>
