【中文标题】为啥在尝试将 Hibernate Spatial 用于 Spring Boot 项目时出现此错误？实例化异常【英文标题】：Why I have this error trying to use Hibernate Spatial into a Spring Boot project? InstantiationException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 【发布时间】：2016-10-25 13:12:09 【问题描述】：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）并且 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）并且据我了解 Hibernate Spatial原生进入 Hibernate 5。
所以，这是我的 pom.xml 内容：

所以，如你所见，我添加了这个依赖项：
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-spatial</artifactId>
<version>5.0.2.Final</version>
</dependency>
我认为我需要将地理类型设为 Point（但我完全不确定）。
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;
应该映射数据库 accommodation 表的字段，名称为 geographical_position 和 Point 作为数据类型。
在发布的示例中使用 @Type(type="org.hibernate.spatial.GeometryType") 而不是 GeolatteGeometryType 但在我的 org.hibernate 中。 spatial.* 包我没有 GeometryType 但我可以找到这个 GeolatteGeometryType 类（我认为这可能是 Hibernate 5 提供的较新的实现，但是我不确定）。
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

有什么问题？我错过了什么？我该如何解决这个问题？
【问题讨论】：
从您的application.properties 来看，您正在努力不使用自动配置功能。旁边使用正确版本的hibernate-spatial 使用$hibernate.version 而不是定义版本。
@M.Deinum 这个“自动配置功能”到底是什么？
你有像 db.url, hibernate.dialect 这样的东西，Spring Boot 没有使用/使用这些东西，所以你必须手动配置，而不是让 Spring Boot 自动配置 DataSource 和 @987654334 @。不管怎样，我怀疑您使用了错误的版本，并且如上所述在版本字段中使用$hibernate.version 来获取正在使用的休眠版本的匹配版本。使用@Type("geolatte_geometry") 而不是你现在拥有的。
@M.Deinum 所以我已经导入了 Hibernate Spatial 5.0.11（与使用的 Hibernate 版本相同）但我得到了同样的错误：Caused by: java.lang.NoSuchMethodException: org.hibernate .spatial.GeolatteGeometryType.@Type("geolatte_geometry") 而不是你现在拥有的（如参考指南中所述）。
【参考方案1】：
这是一个简单的例子（添加以供将来参考）在 Spring-boot 中使用休眠空间。
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
【讨论】：
【参考方案2】：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，您不需要对您的班级成员使用任何 @Type 注释。
【讨论】：
以上是关于为啥在尝试将 Hibernate Spatial 用于 Spring Boot 项目时出现此错误？实例化异常的主要内容，如果未能解决你的问题，请参考以下文章
Hibernate Spatial PostGIS 1.1.1 映射到视图而不是表
为啥我在尝试实现 Hibernate 多对多映射时遇到此错误？
Tapestry 5.3.8 + Jetty + Hibernate 4.3.5 + XAMPP 1.8.3 - IdClass 使用（派生）实体，为啥在尝试合并时它们会分离？
