如何使用GDAL Java绑定编写向量文件？

import org.gdal.ogr.DataSource;
import org.gdal.ogr.Driver;
import org.gdal.ogr.Feature;
import org.gdal.ogr.FeatureDefn;
import org.gdal.ogr.FieldDefn;
import org.gdal.ogr.Geometry;
import org.gdal.ogr.ogr;

public class GDALVectorFileWriter {
    public static void main(String[] args) {
        // 注册所有的GDAL驱动
        ogr.RegisterAll();

        // 创建数据源
        DataSource dataSource = ogr.GetDriverByName("ESRI Shapefile").CreateDataSource("output.shp");

        // 创建图层
        String layerName = "points";
        ogr.Layer layer = dataSource.CreateLayer(layerName, null, ogr.wkbPoint);

        // 添加字段
        FieldDefn fieldDefn = new FieldDefn("name", ogr.OFTString);
        fieldDefn.SetWidth(32);
        layer.CreateField(fieldDefn);

        // 创建要素
        FeatureDefn featureDefn = layer.GetLayerDefn();
        Feature feature = new Feature(featureDefn);
        feature.SetField("name", "Point 1");

        // 创建几何对象
        Geometry geometry = new Geometry(ogr.wkbPoint);
        geometry.AddPoint(0, 0);
        feature.SetGeometry(geometry);

        // 将要素添加到图层
        layer.CreateFeature(feature);

        // 释放资源
        feature.delete();
        dataSource.delete();
    }
}
