How to map an entity to multiple tables in Hibernate?

Question

Java

I'm trying to map an entity Studentto multiple tables: students, addresses, hobbies. The keys in tables addressesand hobbiesare also foreign and refer to the table 's primary key students. That is, the main table students, and the rest - auxiliary. Here are the class descriptions:
Student

package entity;    
import javax.persistence.*;

@Entity
@Table(name = "students")
@SecondaryTables({
        @SecondaryTable(name = "hobbies"),
        @SecondaryTable(name = "addresses"),
})
public class Student {
    @Id
    @Column(name = "student_id")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    private String name;

    @Column(table = "hobbies")
    private String hobby;

    @Column(table = "addresses")
    @Embedded
    private Address address;

    public Student(){}

    public Student(String name, String hobby, Address address){
        this.name = name;
        this.hobby = hobby;
        this.address = address;
    }
}

address

package entity;    
import javax.persistence.*;

@Embeddable
public class Address {

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

    public Address(){}

    public Address(String street){
        this.street = street;
    }
}

As a result, the String hobbyclass field Studentis displayed in a separate table hobbieswithout problems, but the Address addressdisplay fails. That is, the table addressesis created, and the foreign key is registered in it, but the data is not received (the table is empty). In addition, addressesthere is only one field in the table - student_id, and streetfor some reason the field is missing.
The data is created like this:

public static void main(String[] args) {
    StudentService service = new StudentService();
    try {
        Student student = service.create(
                new Student("Вася", "Лыжи", new Address("ул. Ленина"))
        );
        Student student2 = service.create(
                new Student("Петя", "Хоккей", new Address("ул. Фрунзе"))
        );
    } catch (DBException e){
        System.out.println("что-то пошло не так");
    }
    DBService.close();
}

This is the service layer:

package service;

import dao.*;
import exception.DBException;
import entity.Student;
import org.hibernate.HibernateException;
import org.hibernate.Transaction;

import javax.persistence.NoResultException;

public class StudentService {

    public StudentService(){}

    public Student create(Student student) throws DBException {
        Transaction transaction = DBService.getTransaction();
        try {
            StudentDao studentDao = DaoFactory.getStudentDao();
            Long studentId = studentDao.create(student);
            student = studentDao.get(studentId);
            transaction.commit();
            return student;
        } catch (HibernateException | NoResultException | NullPointerException e) {
            DBService.transactionRollback(transaction);
            throw new DBException(e);
        }
    }
}

Why is the table addressesempty and how to make it so that it has the correct structure (there was a field street) and it is filled with data? There are no warnings or errors when executing (but there are no requests to insert data into the table addresses):

As far as I know, @Embedded indicates that this object will be stored in the parent table (at least in my project). That is, the street column will be located in the students table and will be filled in there. Check the data in the students table
