Java Hibernate Spatial:Type org.hibernatespatial.GeometryUserType

我使用的是HibernateSpatial版本4.0-M1。我正在学习教程。但是，我的代码失败，出现以下错误：

org.hibernate.MappingException:无法确定org.hibernatespatial.GeometryUserType的类型，位于#table#u name#处的列#geometry#

我的会话工厂创建类如下所示：

public class HibernateUtil {
    private static final SessionFactory sessionFactory;

    static {
        try {
            // Create the SessionFactory from hibernate.cfg.xml
            sessionFactory = new AnnotationConfiguration().configure().buildSessionFactory();
        } catch (Exception ex) {
            // Make sure you log the exception, as it might be swallowed
            System.err.println("Initial SessionFactory creation failed." + ex);
            throw new ExceptionInInitializerError(ex);
        }
    }

    public static SessionFactory getSessionFactory() {
        return sessionFactory;
    }
}

    <mapping class="com.testapp.model.EntityClassWithAnnotations" />

</session-factory>

@Entity
@Table(name = "table_name")
public class MyEntityClass implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue
    @Column(name = "gid")
    private Long gid;

    @Column(name = "adm1_name")
    private String  adminName;

    private String adminCode;

    @Column(name = "pmal")
    private Double pmale;

    @Column(name = "pfem")
    private Double pfemale;

    @Type(type = "org.hibernatespatial.GeometryUserType")
    @Column(name = "the_geom", nullable = true)
    private Geometry geom;

    public MyEntityClass() {}

    public Long getGid() {
        return gid;
    }

    public void setGid(Long gid) {
        this.gid = gid;
    }

    public String getAdminName() {
        return adminName;
    }

    public void setAdmin_name(String adminName) {
        this.adminName = adminName;
    }

    public String getAdminCode() {
        return adminCode;
    }

    public void setAdmin_code(String adminCode) {
        this.adminCode = adminCode;
    }

    public Double getPmale() {
        return pmale;
    }

    public void setPmale(Double pmale) {
        this.pmale = pmale;
    }

    public Double getPfemale() {
        return pfemale;
    }

    public void setPfemale(Double pfemale) {
        this.pfemale = pfemale;
    }

    public Geometry getGeom() {
        return geom;
    }

    public void setGeom(Geometry geom) {
        this.geom = geom;
    }
}

在寻找可能的原因后，我发现这与我的配置有关。我的

hibernate.cfg.xml

如下所示：

public class HibernateUtil {
    private static final SessionFactory sessionFactory;

    static {
        try {
            // Create the SessionFactory from hibernate.cfg.xml
            sessionFactory = new AnnotationConfiguration().configure().buildSessionFactory();
        } catch (Exception ex) {
            // Make sure you log the exception, as it might be swallowed
            System.err.println("Initial SessionFactory creation failed." + ex);
            throw new ExceptionInInitializerError(ex);
        }
    }

    public static SessionFactory getSessionFactory() {
        return sessionFactory;
    }
}

已编辑：我想我在hibernate.cfg文件中看到了错误，您使用了错误的方言

将方言行替换为：

<property name="hibernate.dialect" value="org.hibernate.spatial.dialect.postgis.PostgisDialect"/>

---

在我的例子中，

hibernate spatial.jar

丢失，其中包括

org.hibernatespatial.GeometryUserType

我们正在使用maven和hibernate spatial的旧1.1.1版本，因此在我将以下内容添加到pom之后，一切都很好：

org.hibernatespatial
冬眠空间
1.1.1

我的映射如上图所示。我正在使用注释。我正在更新代码以包含实体类。至于数据库，我正在与其他应用程序一起使用，主要是openlayers。所以，我认为问题不在于我的数据库。谢谢@Eduardo。改变方言似乎没有效果。它可能是其他东西，而不是方言。好吧，你的地图是好的，你的方言是好的，你的数据库是好的，所以它一定是查询？我不这么认为，我会根据教程再次回顾Hibernate/JPA配置
