Java 休眠不支持操作异常

我使用

Spring+maven+hibernatespatial

。我需要从

MySql

数据库下载表。我创建了整个应用程序，在运行时我得到了以下信息：

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

谢谢你的建议

编辑：此异常导致query.list（）；由此（点类型为点）：

公共列表findByCompany（长公司ID）{
Session Session=sessionFactory.openSession（）；
Query Query=session.createQuery（“从地质点选择点”）；
List rows=query.List（）；
返回行；

对于hql查询，查询看起来很奇怪，请尝试：

---

从Hibernate spatial网站中的地理点p

选择p，我看到以下内容：

HibernateSpatialVersion4.0与Hibernate4.x兼容

---

但是您说您正在使用Hibernate core 3.6.9。也许您需要升级您的Hibernate版本？

您能显示导致此异常的代码吗？在此处发布Hibernate查询？尝试在您的Hibernate中调试代码查询问题我的代码显示在已编辑的帖子中

public List<?> findByCompany(long companyId) {

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

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