How to make spring boot, spatial hibernate and postgis work? - spring-boot

Question

I can't start my spring boot(2.6.3) project with hibernate-spatial in create mode.
It tells me that type "geometry does not exist".
The geometry type comes from the hibernate-spatial library.
However, I applied everything necessary:
add hibernate-spatial dependency (my version 5.6.3.Final)
use the org.hibernate.spatial.dialect.postgis.PostgisDialect dialect
Moreover this class is deprecated and the documentation corresponding to the same version, it still indicates to use it, I do not understand anything (https://docs.jboss.org/hibernate/orm/5.6/userguide /html_single/Hibernate_User_Guide.html#spatial)
Use Geometry type from geolatte group or jts group
Despite that I have an error where it cannot create the table because the type "geometry does not exist".
Here are my maven dependencies:

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

<groupId>org.hibernate</groupId>

public void setAge(String age) {

}
public Long getId() {

}
}
My repository class :
package org.test.hibernate.spatial;
import org.springframework.data.jpa.repository.JpaRepository;
public interface PersonRepository extends JpaRepository<Person, Long> {
}
My boot class :
package org.test.hibernate.spatial;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

public class TestHibernateSpatialApplication implements CommandLineRunner {
public static void main(String[] args) {
SpringApplication.run(TestHibernateSpatialApplication.class, args);
}
public void run(String... args) throws Exception {
}
}
My postgreSQL database is 14 version.
Somebody have any idea what is wrong ?

PostGIS is a Postgres extension, which needs to be enabled for each database:
Once PostGIS is installed, it needs to be enabled (Section 3.3, “Creating spatial databases”) or upgraded (Section 3.4, “Upgrading spatial databases”) in each individual database you want to use it in.
[...]
Run the following SQL snippet in the database you want to enable spatially:
CREATE EXTENSION IF NOT EXISTS plpgsql;
CREATE EXTENSION postgis;
Also be aware that the extension is by default installed to the default schema (e.g. public). So when using the currentSchema option, be sure to not accidentally exclude the schema postgis was installed into. To prevent this, one could either add the postgis schema to the currentSchema (e.g. jdbc:postgresql://localhost:5432/tst?currentSchema=app1,public), or move postgis to the preferred schema.
