java - 为什么在尝试将 Hibernate Spatial 用于 Spring Boot 项目时出现此错误？实例化异常

Question

我正在尝试将Hibernate Spatial配置到我正在处理的Spring Boot项目中，但我发现了一些问题。

我正在使用MariaDB（所以它是MySql）和 Hibernate 之前已更正配置（我将它用于所有非 GIS 功能，没有任何问题）。

我开始使用本教程： http ://www.hibernatespatial.org/documentation/02-Tutorial/01-tutorial4/

但是我使用的是Hibernate 5而不是 Hibernate 4 （我可以在我的外部库中看到我有Hibernate 5.0.11）并且据我所知， Hibernate Spatial 本身就是Hibernate 5。

所以，这是我的pom.xml内容：

<?xml version="1.0" encoding="UTF-8"?>

            </plugin>
        </plugins>
    </build>

</project>

因此，如您所见，我添加了此依赖项：

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-spatial</artifactId>
    <version>5.0.2.Final</version>
</dependency>

我认为我需要它的地理类型为Point（但我绝对不确定）。

然后我有这个映射表的实体类：

@Entity
@Table(name = "accomodation")
public class Accomodation implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id")
    private long id;
    //private Integer id;

    /*@ManyToOne
    private Users users;
    */

    @OneToMany(mappedBy = "accomodation")
    private List<Room> rooms;

    private String name;

    @Column(name = "description")
    @Type(type="text")
    private String description;

    @Column(name = "geographical_position")
    @Type(type="org.hibernate.spatial.GeolatteGeometryType")
    private Point location;

    ...........................................................
    ...........................................................
    ...........................................................
    CONSTRUCTOR AND GETTER AND SETTER METHODS

    ...........................................................
    ...........................................................
    ...........................................................
}

在这个类中，我添加了这个字段：

@Column(name = "geographical_position")
@Type(type="org.hibernate.spatial.GeolatteGeometryType")
private Point location;

这应该映射数据库住宿表的字段，名称为geo_position和Point作为数据类型。

在发布的示例中使用@Type(type="org.hibernate.spatial.GeometryType")代替GeolatteGeometryType但在我的org.hibernate.spatial.*包中我没有GeometryType但我可以找到这个GeolatteGeometryType类（我认为也许可能是 Hibernate 5 提供的较新的实现，但我不确定）。

当我启动我的应用程序时，我在堆栈跟踪中收到以下错误消息：

这也是我的application.properties配置文件：

hibernate.show_sql:true
hibernate.hbm2ddl.auto:validate

问题是什么？我错过了什么？我该如何解决这个问题？

这是将休眠空间与 Spring-boot 一起使用的简单示例（添加以供将来参考）。

添加 spring-boot-starter-data-jpa、hibernate-spatial 和 mydql 连接器 maven 依赖项。

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
        </dependency>

        <dependency>
            <groupId>org.hibernate</groupId>
            <artifactId>hibernate-spatial</artifactId>
            <version>${hibernate.version}</version>
        </dependency>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <scope>runtime</scope>
        </dependency>

创建实体类。

@Entity
public class KSpatial implements Serializable {

    private static final long serialVersionUID = 1L;
    @Id
    @GeneratedValue
    private int spId;
    private int roadId;
    private Point<G2D> currentPosition;
    //getters and setters

}

DAO 实现

@Repository
public class KpSpatialDaoImpl implements KpSpatialDao{

    @Autowired
    private EntityManagerFactory emf;

    private SessionFactory sf;

    @PostConstruct
    public void init() {
        sf = emf.unwrap(SessionFactory.class);
    }

    @Override
    @Transactional
    public boolean add(KpSpatial add) {
        final Session session = sf.getCurrentSession(); 
        session.save(add);
        return true;
    }

    @Override
    @Transactional
    public List<KpSpatial> list() {
        final Session session = sf.getCurrentSession(); 
        return session.createQuery("from KpSpatial", KpSpatial.class).getResultList();
    }

}

最后是 application.properties 文件。

spring.datasource.url=jdbc:mysql://localhost:3306/my_spatial
spring.datasource.username=test
spring.datasource.password=test123
spring.jpa.hibernate.ddl-auto=create-drop
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.dialect=org.hibernate.spatial.dialect.mysql.MySQL56InnoDBSpatialDialect
spring.jpa.properties.hibernate.current_session_context_class=org.springframework.orm.hibernate5.SpringSessionContext

您需要配置一个 SpatialDialect。通用方言不公开空间功能和空间类型。参见文档：http ://docs.jboss.org/hibernate/orm/5.0/userguide/html_single/Hibernate_User_Guide.html#spatial

此外，您不需要在类成员上使用任何 @Type 注释。
