基于udig（开源GIS软件）二次开发(4)

{ ShapefileDataStore myData = new

ShapefileDataStore(shpFile .toURI().toURL());

myData.setStringCharset(Charset.forName(\ SimpleFeatureType ft =

DataUtilities.createType(layerName,

layerFeatures); myData.createSchema( ft); //手动事物 发现有时候给自动回出些问题

Transaction tran = new DefaultTransaction(); fw = myData.getFeatureWriter(layerName, tran); GeometryFactory gf = new

GeometryFactory(); for(DemoPoint point : data)

{ Geometry geo = gf.createPoint(new Coordinate(point.getLon(), point.getLat()));

SimpleFeature sf = (SimpleFeature) fw.next(); sf.setDefaultGeometry(geo); //添加属性

sf.setAttribute(\ fw.write();

} fw.close(); tran.commit(); tran.close(); } catch (IOException e) { // TODO Auto-generated catch block

e.printStackTrace(); } catch (SchemaException e) { // TODO Auto-generated catch block e.printStackTrace(); } finally

{ try { if(fw != null) fw.close(); } catch (IOException

e) { // TODO Auto-generated catch block

e.printStackTrace(); } } return shpFile.getAbsolutePath(); } d、 d 创建一个新的地图，加载我们刚才生成的shp图层文件 /** * 创建一个新地图并打开shp图层文件 * @param path 文件路径 */ protected void createMapAndOpenShp(String path) { IRepository local =

CatalogPlugin.getDefault().getLocal(); IService service = null;

List<IGeoResource> resources = null; try { service =

local.acquire( URLUtils.fileToURL(new

File(path)), new

NullProgressMonitor()); resources = (List<IGeoResource>) service.resources(new NullProgressMonitor()); //发布 ApplicationGIS.createAndOpenMap(resources); } catch (IOException e) { // TODO Auto-generated catch block

e.printStackTrace(); } } 5、注意事项插件中引用要因为udig的applicationgis类,并且需要生成图层，所以在当前插件里我们要引入5个插件（本次的开发环境udig为1.2的版本）： 创建product文件后，最好引入udig的所有包(新手必须). 6、1、 好了 打开看看效果
