Neo4j Spatial数据导入
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();
}
}
}
