包路径：org.locationtech.jts.geom.Geometry
类名称：Geometry
方法名：setSRID

Geometry.setSRID介绍

[英]Sets the ID of the Spatial Reference System used by the Geometry.

NOTE: This method should only be used for exceptional circumstances or for backwards compatibility. Normally the SRID should be set on the GeometryFactory used to create the geometry. SRIDs set using this method will not be propagated to geometries returned by constructive methods.
[中]设置Geometry使用的空间参照系统的ID。
注意：此方法仅适用于特殊情况或向后兼容性。通常，应在用于创建几何图形的GeometryFactory上设置SRID。使用此方法设置的SRID不会传播到构造方法返回的几何体。
