org.hibernate.MappingException:否JDBC类型的方言映射:2002 [英] org.hibernate.MappingException: No Dialect mapping for JDBC type: 2002
问题描述
当我尝试执行JPA nativeQuery以获取几何字段类型时,出现 org.hibernate.MappingException:No对于JDBC类型:2002
的Dialect映射。 / p>
我使用Oracle和 org.hibernatespatial.oracle.OracleSpatial10gDialect
。
几何字段映射为:
@Column(name =geometry)
@Type(type =org.hibernatespatial.GeometryUserType)
private几何几何;
// ...
List< Object> listFeatures = new LinkedList< Object>();
Query query = entityManager.createNativeQuery(
SELECT+ slots +,geometry FROM edtem_features feature,edtem_dades dada WHERE+
feature。+ tematic.getIdGeomField )+= dada。+ tematic.getIdDataField()+
AND dada.capesid =+ tematic.getCapa()。getId()+
AND feature.geometriesid =+ tematic。 。getGeometria()的getId());
listFeatures.addAll(query.getResultList());
这是我在spring + struts2上的hibernate配置
< bean id =entityManagerFactory
class =org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean>
< property name =dataSourceref =dataSource/>
< property name =jpaVendorAdapter>
< bean class =org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter>
< property name =databasePlatformvalue =org.hibernatespatial.oracle.OracleSpatial10gDialect/>
< property name =showSqlvalue =true/>
< / bean>
< / property>
< property name =jpaProperties>
<道具>
< prop key =hibernate.dialect> org.hibernatespatial.oracle.OracleSpatial10gDialect< / prop>
< prop key =hibernate.default_schema> my_schema< / prop>
< /道具>
< / property>
< / bean>
这怎么解决?或者如何强制几何的类型得到这个工作?
您可以尝试使用以下映射定义: b>
@Column(name =geometry,columnDefinition =Geometry,nullable = true)
private几何几何;
而不是:
@Column(name =geometry)
@Type(type =org.hibernatespatial.GeometryUserType)
private几何几何;
I'm getting org.hibernate.MappingException: No Dialect mapping for JDBC type: 2002
when I try to do a JPA nativeQuery to get a geometry field type.
I'm using Oracle and org.hibernatespatial.oracle.OracleSpatial10gDialect
.
The geometry field is mapped as:
@Column(name="geometry")
@Type(type = "org.hibernatespatial.GeometryUserType")
private Geometry geometry;
// ...
List<Object> listFeatures = new LinkedList<Object>();
Query query = entityManager.createNativeQuery(
"SELECT "+ slots +" , geometry FROM edtem_features feature, edtem_dades dada WHERE" +
" feature."+ tematic.getIdGeomField() +" = dada."+ tematic.getIdDataField()+
" AND dada.capesid= "+ tematic.getCapa().getId() +
" AND feature.geometriesid= "+ tematic.getGeometria().getId());
listFeatures.addAll(query.getResultList());
This is my hibernate configuration over spring+struts2
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="databasePlatform" value="org.hibernatespatial.oracle.OracleSpatial10gDialect" />
<property name="showSql" value="true" />
</bean>
</property>
<property name="jpaProperties">
<props>
<prop key="hibernate.dialect">org.hibernatespatial.oracle.OracleSpatial10gDialect</prop>
<prop key="hibernate.default_schema">my_schema</prop>
</props>
</property>
</bean>
How can this be solved? Or how to force the type of the geometry to get this working?
Could you try with the following mapping definition:
@Column(name = "geometry", columnDefinition="Geometry", nullable = true)
private Geometry geometry;
Instead of:
@Column(name="geometry")
@Type(type = "org.hibernatespatial.GeometryUserType")
private Geometry geometry;
