这个方法应该用我传递给它的新特性替换数据库中的特性。
private static void replaceBoundaryShape(FeatureCollection<SimpleFeatureType, SimpleFeature> dbFeatures) throws IOException, CQLException{
FeatureStore<SimpleFeatureType, SimpleFeature> fs = null;
FeatureSchemaFactory factory = FeatureSchemaFactory.init();
DataStore geoStore = initDataStore();
try{
fs = (FeatureStore) geoStore.getFeatureSource(factory.getFieldFeatureSchema().getTypeName());
fs.setTransaction(new DefaultTransaction());
for(FeatureIterator<SimpleFeature> iterator = dbFeatures.features(); iterator.hasNext();){
SimpleFeature simpleFeature = iterator.next();
Number fieldId = (Number) simpleFeature.getAttribute(FeatureSchemaFactory.FIELD_ID);
Filter filter = createSearchByIdFilter(fieldId.longValue());
fs.removeFeatures(filter);
}
fs.addFeatures(dbFeatures);
fs.getTransaction().commit();
}catch(CQLException ex){
throw new CQLException(ex.getMessage());
}
}
这是我创建传递以替换边界形状的特征集合的地方
private static FeatureCollection<SimpleFeatureType, SimpleFeature> createBoundaryFeatures(SimpleFeatureType dbSchema, Collection<FieldFeature> fields){
List<SimpleFeature> result = new ArrayList<SimpleFeature>(fields.size());
SimpleFeatureBuilder builder = new SimpleFeatureBuilder(dbSchema);
for(FieldFeature f: fields){
builder.set("BNDRS", f.getGeometries());
builder.set("FIELD", f.getField());
builder.set("FID", f.getFid());
builder.set("GROWER", f.getGrower());
builder.set("SIMPLIFIED_BNDRS", f.getSimplifiedGeometries());
result.add(builder.buildFeature(null));
}
return DataUtilities.collection(result);
}
这是我从文件路径和指定字段获取字段特征的地方：
private static Collection<FieldFeature> convertShpFile(String filePath, Field field) throws MalformedURLException, IOException{
@SuppressWarnings("deprecation")
ShapefileDataStore source = new ShapefileDataStore(new File(filePath).toURL());
Collection<FieldFeature> result = new LinkedList<FieldFeature>();
DefaultQuery query = new DefaultQuery();
query.setCoordinateSystemReproject(DefaultGeographicCRS.WGS84);
FeatureCollection queryResult = source.getFeatureSource().getFeatures(query);
FeatureIterator<SimpleFeature> fi = queryResult.features();
while(fi.hasNext()){
SimpleFeature feature = fi.next();
FieldFeature fieldFeature = new FieldFeature();
Object defaultGeometry = feature.getDefaultGeometry();
if(defaultGeometry instanceof Polygon){
Polygon polygon = (Polygon) defaultGeometry;
Polygon[] polygons = {polygon};
defaultGeometry = geometryFactory.createMultiPolygon(polygons);
}
fieldFeature.setField(field.getId());
fieldFeature.setGeometries(defaultGeometry);
fieldFeature.setSimplifiedGeometries(GeoHelper.simplifyGeometry((Geometry) defaultGeometry));
result.add(fieldFeature);
}
fi.close();
source.dispose();
return result;
}
错误发生在 replaceBoundaryShape 方法的 fs.addFeatures(dbFeatures) 行。
删除功能不会引发错误，但是当我调用 addFeatures 函数时，我收到此 AbstractMethodError: java.lang.AbstractMethodError: org.geotools.jdbc.PreparedStatementSQLDialect.setGeometryValue(Lcom/vividsolutions/jts/geom/Geometry;IILjava/lang/类；Ljava/sql/PreparedStatement；I)V
将功能插入 JDBCDataStore 时似乎会引发错误
编辑：这是完整的堆栈跟踪
