How to avoid NULL values on Embedded entities

#1

Hi there. I'm new on this. trying to learn.

I'm trying to make a value non nulleable. So, when I try to upload to the DB this field as null, it give me an error.

I tried this, but it didn't work:

public class Pedido {
    @Id @GeneratedValue
    private long id;
   
    @Embedded private Direccion origen;
    @ManyToOne private Cliente cliente; //Opcional
   
    @Basic(optional=false) private Date fechaYhora; //Fecha en que se debe enviar el coche

}

public class Direccion {
    @Basic(optional=false) private String calle;
    @Basic(optional=false) private int numero;
    @Basic(optional=false) private String ciudad;
    @Basic(optional=false) private String provincia;
    @Basic(optional=false) private String pais;
    @Basic(optional=false) private int cp;

}

 

And how to make the emmbedeable Direccion not nulleable?

In the code above, the optional=false, works only on fechaYhora, but it doesn't work inside Direccion fields.

Sorry if my english is not perfecto, just ask if i'm not clear

 

Edit:

Sorry. Solved. The code was working, the problem was that i'm savin an empty string "" (not null)
