使用GeoTools讀取ShapeFile文件，測試版本為geotools-16.1。所需jar包有這里寫圖片描述

package com.test;import java.io.File;import java.nio.charset.Charset;import java.util.ArrayList;import java.util.List;import org.geotools.data.shapefile.ShapefileDataStore;import org.geotools.data.shapefile.ShapefileDataStoreFactory;import org.geotools.data.shapefile.files.ShpFiles;import org.geotools.data.shapefile.shp.ShapefileReader;import org.geotools.data.simple.SimpleFeatureCollection;import org.geotools.data.simple.SimpleFeatureSource;import com.vividsolutions.jts.geom.Geometry;import com.vividsolutions.jts.geom.GeometryFactory;public class ShapeFileUtils { /** * 獲取shape文件feature集合 * @param shapePath shape文件路徑 * @param charSet 讀取shape文件編碼 * @return SimpleFeatureCollection */ public static SimpleFeatureCollection ReadShapeFileFeatures(String shapePath, String charSet){ SimpleFeatureCollection sfc = null; ShapefileDataStoreFactory dataStoreFactory = new ShapefileDataStoreFactory(); ShapefileDataStore sds = null; try { sds = (ShapefileDataStore)dataStoreFactory.createDataStore(new File(shapePath).toURI().toURL()); sds.setCharset(Charset.forName(charSet)); SimpleFeatureSource featureSource = sds.getFeatureSource(); sfc = featureSource.getFeatures(); } catch (Exception e) { e.PRintStackTrace(); }finally{ sds.dispose(); } return sfc; } /** * 讀取ShapeFile中的空間數據 * @param shapeFilePath * @return List<Geometry> */ public static List<Geometry> getGeometriesFromShapeFile(String shapeFilePath){ List<Geometry> result = new ArrayList<Geometry>(); try { ShpFiles file = new ShpFiles(shapeFilePath); ShapefileReader reader = new ShapefileReader(file, false, false, new GeometryFactory()); while(reader.hasNext()){ result.add((Geometry)reader.nextRecord().shape()); } reader.close(); } catch (Exception e) { e.printStackTrace(); } return result; }}

測試類如下。
