org.postgresql.util.PSQLException: ERROR: Invalid endian flag value encountered
我咨询了很多问题还是没有找到解决问题的方法
我正在做一个应用程序，其中一些 类 具有几何或点类型的属性，但是在进行持久性测试时，一切顺利，直到我尝试保存一个点。
我想补充一点，我需要使用这种类型的几何体 (import org.locationtech.jts.geom.Point;)，我找到的所有解决方案都是这种类型 (import com.vividsolutions.jts.geom.Point;)
我认为问题出在序列化器方面，我有一个应该可以正常工作但函数给我一个错误。

最后我还没有找到 locationtech 几何的解决方案，也许是因为它比 vividsolutions 更新，并且使用 vividsolutions 一切正常，所以我的解决方案是使用 vividsolutions 而不是 locationtech。
另一个我发现但错误的事实是序列化程序（它不会失败地更改为 vividsolutions）与数据库无关，这是 hibernate 专门负责的。
我咨询了很多问题还是没有找到解决问题的方法
我正在做一个应用程序，其中一些 类 具有几何或点类型的属性，但是在进行持久性测试时，一切顺利，直到我尝试保存一个点。
我想补充一点，我需要使用这种类型的几何体 (import org.locationtech.jts.geom.Point;)，我找到的所有解决方案都是这种类型 (import com.vividsolutions.jts.geom.Point;)
