我正面临着PostgreSQL的earthdistance扩展的问题。在HQL中使用earthdistance Postgresql扩展
继this指导，我已经添加了以下扩展名：
CREATE EXTENSION cube;
CREATE EXTENSION earthdistance;
我试图逃避的Postgres命令行下面的SQL查询和一切工作正常：
SELECT * FROM table
WHERE earth_box(ll_to_earth(40.463444, -3.637716), 2000) @> ll_to_earth(table.lat, table.lon)
当我尝试在HQL中运行相同的查询，我得到以下例外：
org.hibernate.QueryException: unexpected char: '@' [Select 1 from table WHERE earth_box(ll_to_earth(40.463444, -3.637716), 2000) @> ll_to_earth(table.lat, table.lon)]

...
它告诉我HQL方言不能识别安装的Postgres扩展。
是否有人可以在HQL中使用该操作符？
