Question

使用 hibernate-entitymanager 4.2.8.Final hibernate-spatial 4.0

Session session = sessionProvider.get();
Criteria criteria = session.createCriteria(UEntity.class);
criteria.add(SpatialRestrictions.contains("geometry", point));
List<UEntity> containedByMbr = criteria.list();

我得到以下例外情况。任何建议都非常值得注意。

此错误的含义是您的数据库方言不支持空间限制。

Hibernate无法将SpatialRestriction转换为数据库的SQL，因为该数据库方言不支持Spatial操作。

更改数据库或强制将Hibernate的方言强制为支持空间操作的方言。

java.lang.IllegalStateException：Dialect必须是空间启用的方言
