此方法运行时没有任何错误,但是当我注销并登录到我的 Web 应用程序的同一页面时,此方法一次又一次地运行而没有问题,但随后抛出此异常。我正在使用带有 jsf2 和 primefaces 3.5 的 google app engine 1.8.1。此方法是从托管 bean 调用的:
public MapMB () {
eps = EPDAO.getEPList();
populateAdvancedModel(eps);
drawPolilines();
}
void drawPolilines() {
List<Area> areas = Area.readAreas(getFacesContext().getClass().getResource("/map-inksc.svg") );
for (Area area : areas) {
List<Curve> curves = area.getCurves();
Point endPoint = area.getmPoint();
Polyline polyline = new Polyline();
polyline.setStrokeWeight(1);
polyline.setStrokeColor("#FF0000");
polyline.setStrokeOpacity(1);
for (Curve curve : curves) {
polyline.getPaths().add( new LatLng(endPoint.getY(),endPoint.getX()) );
// curve start point is the end point of previous curve (endPoint.getX(),endPoint.getY() )
double step = 0.01;
for (double t=0;t<= 1;t=t+step) {
double x = getCoordFromCurve(endPoint.getX(), endPoint.getX() + curve.getP1().getX(),endPoint.getX() + curve.getP2().getX(),endPoint.getX() + curve.getP3().getX(), t);
double y = getCoordFromCurve(endPoint.getY(), endPoint.getY() + curve.getP1().getY(),endPoint.getY() + curve.getP2().getY(),endPoint.getY() + curve.getP3().getY(), t);
polyline.getPaths().add( new LatLng(y, x) );
}
endPoint = new Point (endPoint.getX() + curve.getP3().getX(), endPoint.getY() + curve.getP3().getY());
}
advancedModel.addOverlay(polyline);
polyline = new Polyline();
}
}
当我不读取任何数据(不要使用上面的 readAreas() )时,一切正常。那么从文件中读取如何与此错误相关联呢?我不明白。
如果有一些我没有放在这里的信息,请说出来。所有这些方法都运行没有错误,然后抛出这个异常
