Neo4j Spatial数据导入-摩杜云开发者社区

首先，安装neo4j数据库。我的开发环境是Ubuntu，安装过程参考官网：Neo4j Debian Packages，安装后配置：Post-installation tasks。

然后安装Neo4j Spatial的插件，参加Github介绍：neo4j-contrib/spatial。即把下载的文件解压到安装目录的plugins目录下$NEO4J_HOME/plugins。

接下来，我们使用Java代码在客户端插入数据到neo4j数据库。
我使用Maven构建工程（需要使用Java8进行maven编译）。pom文件如下：

导入shapefile文件的代码入下：

package cn.tzy.neo4j;

import java.io.File;
import java.io.IOException;

import org.neo4j.gis.spatial.ShapefileImporter;
import org.neo4j.graphdb.GraphDatabaseService;
import org.neo4j.graphdb.Transaction;
import org.neo4j.graphdb.factory.GraphDatabaseFactory;

public class Neo4jEx {

    public static void main(String[] args) throws IOException {
        File storeDir = new File("C:/Users/theone/Desktop/spatial.db");
        GraphDatabaseService database = new GraphDatabaseFactory().newEmbeddedDatabase(storeDir);

        try (Transaction tx = database.beginTx()) {
            ShapefileImporter importer = new ShapefileImporter(database);
            importer.importFile("F:/2016/Data/World/continent.shp", "continent");

            tx.success();
        } finally {
            database.shutdown();
