How to deserialize geolocation point data to a Java entity?

Flowryn :

I am trying to deserialize a point into a java object.

Here is the entity class I am using.

import lombok.Data;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;

import com.vividsolutions.jts.geom.*;



@Data
@Entity(name = "magic_points")
public class MagicPoint {
    @Id
    Integer id;

    @Column(name = "p", columnDefinition="Point")
    private Point point;

    @Column(name = "description")
    private String description;
}

The repository

import com.playground.springplayground.db.entities.MagicPoint;
import com.vividsolutions.jts.geom.Point;
import org.springframework.data.repository.Repository;

public interface MagicPointRepository extends Repository<MagicPoint, Integer> {

    List<MagicPoint> getAllByDescription(String description);
}

And the way how I am calling it.

        List<MagicPoint> magicPoints = magicPointRepository.getAllByDescription("Abc");

I am using the following library for geodata:

compile group: 'com.vividsolutions', name: 'jts', version: '1.13'

Database is a MySql, Ver 8.0.13

And the data I stored in Database:

This is the error I am receiving:

Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.orm.jpa.JpaSystemException: could not deserialize; nested exception is org.hibernate.type.SerializationException: could not deserialize] with root cause

java.io.StreamCorruptedException: invalid stream header: E6100000
    at java.io.ObjectInputStream.readStreamHeader(ObjectInputStream.java:866) ~[na:1.8.0_181]
    at java.io.ObjectInputStream.<init>(ObjectInputStream.java:358) ~[na:1.8.0_181]

Is com.vividsolutions.jts is a good approach for mapping geodata stored in SQL databases? Is it something I am missing? I couldn't find anything related to this until now. The mapping error message doesn't bring any useful information if there is a driver missing or some other dependency I should consider.

EDIT In order to reproduce it on your local machine I added the code on Github

git clone https://github.com/florin-t/deserialize-geolocation-point.git

There is also a README.TXT with some instructions regarding the Database and application.config.

Catalin :

set the mysql dialect to org.hibernate.spatial.dialect.mysql.MySQL56InnoDBSpatialDialect eg. spring.jpa.properties.hibernate.dialect=org.hibernate.spatial.dialect.mysql.MySQL56InnoDBSpatialDialect

also make sure you do not have incompatibilities with the hibernate library (if you use hibernate-spatial 5.2.5.Final you project works)
