我Point
在 geomesa 中使用几何类型来获取特征类型中的强经纬度细节。在存储新功能的用例中,我没有 lat-long 的价值,所以我尝试null
为函数发送对象createPoint
,但库“jts”在处理空几何类型时抛出异常。这是源代码。通过查看jts
库的实现,在geomesa Point中存储null似乎很困难。我可以尝试哪些可能性?这是我的代码的快照:
sf.setAttribute(Attributes.GEOMETRY.getValue(), JTSFactoryFinder.getGeometryFactory().createPoint((Coordinate)null/*new Coordinate(event.lat, event.lng)*/));
附加异常日志:
