我试图从Geotools启动Quickstart
以下是代码:
package org.geotools.tutorial.quickstart;
import java.io.File;
import org.geotools.data.FileDataStore;
import org.geotools.data.FileDataStoreFinder;
import org.geotools.data.simple.SimpleFeatureSource;
import org.geotools.map.FeatureLayer;
import org.geotools.map.Layer;
import org.geotools.map.MapContent;
import org.geotools.styling.SLD;
import org.geotools.styling.Style;
import org.geotools.swing.JMapFrame;
import org.geotools.swing.data.JFileDataStoreChooser;
/**
* Prompts the user for a shapefile and displays the contents on the screen in a map frame.
* <p>
* This is the GeoTools Quickstart application used in documentationa and tutorials. *
*/
public class Quickstart {
/**
* GeoTools Quickstart demo application. Prompts the user for a shapefile and displays its
* contents on the screen in a map frame
*/
public static void main(String[] args) throws Exception {
// display a data store file chooser dialog for shapefiles
File file = JFileDataStoreChooser.showOpenFile("shp", null);
if (file == null) {
return;
}
FileDataStore store = FileDataStoreFinder.getDataStore(file);
SimpleFeatureSource featureSource = store.getFeatureSource();
// Create a map content and add our shapefile to it
MapContent map = new MapContent();
map.setTitle("Quickstart");
Style style = SLD.createSimpleStyle(featureSource.getSchema());
Layer layer = new FeatureLayer(featureSource, style);
map.addLayer(layer);
// Now display the map
JMapFrame.showMap(map);
}
}
运行时:
JFileDataStoreChooser正确打开。
所以我从那里选择了一个.shp文件: naturalearthdata(50m-cultural-vectors)
教程中显示的主框架在屏幕上正确绘制...但没有地图。
如果我点击缩放按钮上的框架(我认为会再次绘制地图),代码会崩溃,我会收到以下错误:

并且maven依赖项已正确更新:
以下是项目的构建路径:
我也按照教程中的建议成功安装了jai版本: JAI-1_1_3-lib的窗口-i586的-jdk.exe jai_imageio-1_1-LIB - 窗口i586的-jdk.exe
如果有人有任何想法......我还没有找到解决方案!
