java读取shp文件

代码如下：

import org.geotools.data.FeatureSource;
import org.geotools.data.shapefile.ShapefileDataStore;
import org.geotools.feature.FeatureCollection;
import org.geotools.feature.FeatureIterator;
import org.opengis.feature.simple.SimpleFeature;
import org.opengis.feature.simple.SimpleFeatureType;

import java.io.File;
import java.io.IOException;
import java.net.MalformedURLException;
import java.nio.charset.Charset;

public class ShpRead {
public void readSHP(String shppath, String indexname) {
        ShapefileDataStore shpDataStore = null;
try {
            File shpfile = new File(shppath);
            shpDataStore = new ShapefileDataStore(shpfile.toURI().toURL());
//设置字符编码
Charset charset = Charset.forName("GBK");
            shpDataStore.setCharset(charset);
            String typeName = shpDataStore.getTypeNames()[0];//
FeatureSource<SimpleFeatureType, SimpleFeature> featureSource = null;
            featureSource = shpDataStore.getFeatureSource(typeName);
            FeatureCollection<SimpleFeatureType, SimpleFeature> result = featureSource.getFeatures();
int indexfield = result.getSchema().indexOf(indexname);
            FeatureIterator<SimpleFeature> itertor = result.features();
while (itertor.hasNext()) {
                SimpleFeature feature = itertor.next();
                String fieldstr = feature.getAttribute(indexfield).toString();
            }
            itertor.close();
        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

}
