Question

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

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

有人可以帮助我找到解决方案吗？

我将maven用于neo4j和-spatial

Answer 1

您必须使用为您正在使用的Neo4j版本构建的neo4-spatial版本。尝试更改

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

到

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

Neo4j-spatial无法导入OSM
