Hibernate Spatial 5 - GeometryType [英] Hibernate Spatial 5 - GeometryType

问题描述

将Hibernate-spatial升级到版本5.0.0.CR2后，以下声明不再起作用：

After upgrading Hibernate-spatial to Version 5.0.0.CR2 the following declaration doesn't work anymore:

@Column(columnDefinition = "geometry(Point,4326)")
@Type(type = "org.hibernate.spatial.GeometryType")
private Point position;

带有：

org.hibernate.boot.registry.classloading.spi.ClassLoadingException: Unable to load class [org.hibernate.spatial.GeometryType]

我可以看到Jar-File中不再存在该类。 GeometryType发生了什么，它是如何被替换的？还是要包含另一个jar文件？

As I can see the class doesn't exist in the Jar-File anymore. What happend to the GeometryType and how is it replaced? Or is there another jar-file to include?

编辑：澄清。我正在将Hibernate-Spatial与PostgreSQL-Postgis数据库结合使用。

For clarification. I am using Hibernate-Spatial in Combination with a PostgreSQL-Postgis database.

推荐答案

这个解决方案很容易看到。只需删除@Type注释，因此声明如下所示：

Well the solution is too easy to see. Simply delete the @Type annotation, so the declaration looks like this:

@Column(columnDefinition = "geometry(Point,4326)")
private Point position;

来源：

注意@Type注释。这告诉Hibernate，location属性是Geometry类型。 @Type注释是特定于Hibernate的，并且是唯一需要的非JPA注释。 （在Hibernate的未来版本（版本5及更高版本）中，将不再需要显式声明几何值类型的属性。）

Note the @Type annotation. This informs Hibernate that the location attribute is of type Geometry. The @Type annotation is Hibernate specific, and the only non-JPA annotation that is required. (In future versions of Hibernate (version 5 and later) it will no longer be necessary to explicitly declare the Type of Geometry-valued attributes.)
