hibernate 和 spring 中的持久性

Question

I have a question about Spring and Hibernate and that is, if for example I want to persist two entities at the same time, such as Customer and Address, that when a customer is registered, their address is automatically saved as well.

It is that the address is retrieved from an address api external to my application and I want that information to be saved in the Address entity when the client registers.

My entities are the following:

Customer:

public class Customer{
     
    @Id 
    @GeneratedValue(strategy = GenerationType.IDENTITY) 
    private Long id;

    @NotBlank(message = "no puede estar vació")
    private String nombre;

    @NotBlank(message = "no puede estar vació")
    @Column(name = "apellido_paterno")
    private String apellidoPaterno;

    @NotBlank(message = "no puede estar vació")
    @Column(name = "apellido_materno")
    private String apellidoMaterno;
    
    @NotBlank(message = "no puede estar vació")
    private String telefono;
 
 
    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "address_id")
    @JsonIgnoreProperties({"hibernateLazyInitializer","handler"})
    private Address address;
}

Address:

public class Address{

    @Id 
    @GeneratedValue(strategy = GenerationType.IDENTITY) 
    private Long id;
 
    @NotBlank(message = "no puede estar vació")         
    private String calle;
    
    @NotBlank(message = "no puede estar vació") 
    private String colonia;
    
    @NotNull(message = "no puede estar vació")
    @Column(name = "no_exterior")   
    private Integer noExterior; 
 
    @Column(name = "no_interior")   
    private Integer noInterior;
 
    @NotBlank(message = "no puede estar vació") 
    private String municipio;
    
    @NotNull(message = "no puede estar vació")
    private Integer cp; 
    
     @NotBlank(message = "no puede estar vació")    
    private String estado;
 
    @OneToMany(mappedBy = "adress")
    private List<Customer> customer;
}

Since I have it, the address must already be created so that it can be associated with the client, however, I want that when the client enters their data, including the address, they are created at the same time and the association is maintained.

When you persist the Entity "Customer" you should create a object Customer and a object Address, and set to the Customer the Address object and add to the Customer list in Address object, the object Customer. I mean, you should do it in your business logic layer, or your service.
