Java 具有GeometryUserType参数的Postgis和Oracle空间查询

接下来，我将按照persistence.xml及其映射文件中的配置，将MyClass的实例持久化到Postgis或Oracle数据库中

我将对geom属性进行注释：

public abstract class MyClass (...)
@Type(type = "org.hibernatespatial.GeometryUserType")
  @Column(name = "geom", columnDefinition="Geometry", nullable = true)
protected Geometry geom; (...)

Persistence.xml已配置：

<persistence-unit name="pers_unit_name" transaction-type="JTA">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <jta-data-source>jta_data_source_name</jta-data-source>
    <mapping-file>oracle.hbm.xml</mapping-file>

它将使用默认为该特定参数配置的Hibernate方言，而不是为持久性单元指定的，因此它将输出下面的stacktrace

是否有任何方法可以强制使用持久化单元中为谓词中的特定参数字段定义的一致方言，而不是默认配置的方言
