Hibernate-Spatial, JPA, Spring, MySQL 5.7 (unable to retrieve Point)

Question

I'm using the frameworks as stated in the topic.

this is my part of my jpa properties in application.yml for spring

jpa:
  database: mysql
  hibernate:
    naming:
      physical-strategy: org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl 
  properties:
    hibernate:
      dialect: org.hibernate.spatial.dialect.mysql.MySQL56InnoDBSpatialDialect
      globally_quoted_identifiers: true
  show-sql: true

I'm not sure if this is the right way to trigger SpatialDialect for MySQL5.7

My entity's method for Point

@Type(type = "com.iheartcity.apiapp.geometry.MySQLGeometryType")
@Column(name = "location", nullable = false)
public Point getLocation() {
    return this.location;
}
public void setLocation(Point location) {
    this.location = location;
}

I created a class MySQLGeometryType.java:

package com.iheartcity.apiapp.geometry;

import org.hibernate.spatial.JTSGeometryType;
import org.hibernate.spatial.dialect.mysql.MySQLGeometryTypeDescriptor;

public class MySQLGeometryType extends JTSGeometryType {

    public MySQLGeometryType() {
        super(MySQLGeometryTypeDescriptor.INSTANCE);
    }
}

With the @Type(type = "com.iheartcity.apiapp.geometry.MySQLGeometryType")

it works perfectly. However, when I commented it, I start to get error when running the code to retrieve the data.

Here is the exception:

Answer 1

The actual solution is to remove @Type and use @Column(name = "location", nullable = false, columnDefinition = "Point")

Note that this is for MySQL
