Why I can't retrieve a database field havin "point" as data type using Hibernate5\Spring Data JPA into this Spring Boot project?

Question

I am working on a Spring Boot project and I am going crazy trying to correctly map a point field of a MySql DB (it is MariaDB but it is the same thing...).

To retrieve data I am using Spring Data JPA on Hibernate 5.

I have this accomodation table on my DB:

Field                           Type                            Null            Key             Default             Extra   
id                              bigint(20) unsigned             NO              PRI             NULL                auto_increment
user_id                         bigint(20) unsigned             NO              MUL             NULL    
accomodation_name               varchar(255)                    NO              NULL    
description                     text                            NO              NULL    
nation                          varchar(255)                    NO              NULL    
region                          varchar(255)                    NO              NULL    
province                        varchar(255)                    NO              NULL    
city                            varchar(255)                    NO              NULL    
geographical_position           point                           NO              NULL    
stars                           int(10)                         NO              NULL    
accomodation_typological_id     bigint(20) unsigned             YES             NULL    
accomodation_service_id         bigint(20) unsigned             YES             NULL    
phone                           varchar(255)                    YES             NULL    
mobile                          varchar(255)                    YES             NULL    
fax                             varchar(255)                    YES             NULL    
email                           varchar(255)                    YES             NULL    
time_stamp                      datetime                        YES             NULL    

As you can see this table contain the field geographical_position having point as data type (beloning to MySql opengGIS implementation).

The previous table is mapped by this Accomodation class:

import com.vividsolutions.jts.geom.Point;
import org.hibernate.annotations.Type;

import javax.persistence.*;
import java.io.Serializable;
import java.math.BigInteger;
import java.util.List;

/**
 * Created by Yngve on 30/09/16.
 */
@Entity
@Table(name = "accomodation")
public class Accomodation implements Serializable {


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

    /*@ManyToOne
    private Users users;
    */

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

    @Column(name = "accomodation_name")
    private String name;

    @Column(name = "description")
    @Type(type="text")
    private String description;
    private String phone;
    private String mobile;
    private String fax;
    private String email;
    private Integer stars;

    @Column(name = "geographical_position", columnDefinition="Point")
    private Point location;


    public Accomodation(){

    }

    // GETTER AND SETTER METHODS
}

As you can see the previous point field on the table is mapped by this field on my Java class:

@Column(name = "geographical_position", columnDefinition="Point")
private Point location;

在前面的代码片段中我还插入了Point的使用实现的导入(我在一些教程中找到了它):

import com.vividsolutions.jts.geom.Point;

但我绝对不确定这是必须使用的正确类.

这是我的DAO类实现Spring Data JPA查询(查询是由Spring Data JPA使用方法签名生成的):

@Repository
@Transactional(propagation = Propagation.MANDATORY)
public interface AccomodationDAO extends JpaRepository<Accomodation, Long> {

    //@Query("FROM Accomodation WHERE id = :id")
    Accomodation findById(@Param("id") Long id);
}

问题是使用此JUnuit测试方法测试以前的DAO 方法:

@Test
public void placeSearcherControllerTest() {
    System.out.println("placeSearcherControllerTest START");

    Accomodation accomodation = accomodationDAO.findById(6L);

    System.out.println("placeSearcherControllerTest END");
}

我在IntelliJ控制台中获取以下错误消息:

Hibernate: select accomodati0_.id as id1_0_, accomodati0_.description as descript2_0_, accomodati0_.email as email3_0_, accomodati0_.fax as fax4_0_, accomodati0_.geographical_position as geograph5_0_, accomodati0_.mobile as mobile6_0_, accomodati0_.accomodation_name as accomoda7_0_, accomodati0_.phone as phone8_0_, accomodati0_.stars as stars9_0_ from accomodation accomodati0_ where accomodati0_.id=?

问题肯定是由于住宿类的映射造成的:

@Column(name = "geographical_position", columnDefinition="Point")
private Point location;

因为如果我从我的实体类中删除这个字段,我没有例外,我正确检索住宿对象(不包含位置字段).

Looking at the previous error output I can see that Hibernate generate this SQL query:

select accomodati0_.id as id1_0_, accomodati0_.description as descript2_0_, accomodati0_.email as email3_0_, accomodati0_.fax as fax4_0_, accomodati0_.geographical_position as geograph5_0_, accomodati0_.mobile as mobile6_0_, accomodati0_.accomodation_name as accomoda7_0_, accomodati0_.phone as phone8_0_, accomodati0_.stars as stars9_0_ from accomodation accomodati0_ where accomodati0_.id=6 

that performed directly on my database I obtain the correct record. As content of the previous point field I can see this value [GEOMETRY - 25 B] (what means 25 B?) that downloaded is a file named accomodation-geographical_position.bin.

Performing this other query on the DB:

select id, AsText(geographical_position) from accomodation where id = 6 

I correctly obtatin the coordinates contained in my geographical_position field, infact this i the obtained query output:

id      AsText(geographical_position)
--------------------------------------
6       POINT(41.729086 12.278478)

So the data is correctly stored into the geographical_position having point as data type.

So the problem is related to the mapping of the geographical_position field to the Point location of my entity class.

Searching on stackoverflow it seems to me that the org.hibernate.type.SerializationException: could not deserialize exception something happing when Hibernate can't put the value of a field into a specific Java object so I am having some doubt related the import com.vividsolutions.jts.geom.Point used class to map the point database field (maybe is this a class used on the old version of Hibrnate Spatial or something like this?)

或者它可能是一个Spring Boot配置问题,所以我在这里也放了我的appliction.properties文件代表我的整个应用程序配置:

#No auth  protected
endpoints.shutdown.sensitive=true
#Enable shutdown endpoint
endpoints.shutdown.enabled=true
logging.file=BeTriviusController.log
logging.level.org.springframework.web=DEBUG
logging.level.org.hibernate=ERROR

# Thymeleaf
spring.thymeleaf.cache:false


# DATABASE CONFIG ----------------------------------------------------------------------------------------------------
spring.datasource.url = jdbc:mysql://localhost:3306/betriviustest
spring.datasource.username = root
spring.datasource.password =
spring.datasource.driver-class-name = com.mysql.jdbc.Driver
spring.jpa.properties.hibernate.current_session_context_class=org.springframework.orm.hibernate4.SpringSessionContext

spring.datasource.testWhileIdle = true
spring.datasource.validationQuery = SELECT 1

# Show or not log for each sql query
spring.jpa.show-sql = true

# Hibernate ddl auto (create, create-drop, update, validate)
spring.jpa.hibernate.ddl-auto = validate

#spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy

spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

也许它可能与Hibernate Spatial配置有关？(看起来我很奇怪,因为据我所知,它直接包含在Hibernate 5中,它不再是一个添加和配置的外部项目).

那么,有什么不对？我错过了什么？如何解决此问题并正确地将我的实体类的Point位置映射到具有点作为数据类型的geographic_position表字段的值？
