我用Spring+maven+Hibernate Spatial. 我需要从MySql数据库下载表。我创建了整个应用程序，在运行时我得到了这个：

Hibernate: select geopoint0_.point as col_0_0_ from geo_point geopoint0_

我使用Hibernate -core 3.6.9、mysql 连接器 5.1.10和hibernate spatial 4.0-M1 感谢您的任何建议。

编辑：此异常导致 query.list(); 从此（点类型为 POINT）：

public List<?> findByCompany(long companyId) {

    Session session = sessionFactory.openSession();
    Query query = session.createQuery("select  point from GeoPoint");

    List<?> rows = query.list(); 
        return rows;

对于 hql 查询，查询看起来很奇怪，请尝试：

从地理点 p 中选择 p

从 Hibernate 空间网站我看到以下内容：

Hibernate Spatial 4.0 版与 Hibernate 4.x 兼容

但是你说你使用的是Hibernate core 3.6.9。也许你需要升级你的 Hibernate 版本？
