Create Foreign Key hibernate

Solved and edited correctly:

I can not include an invoice with the customer id. In this case the customer may have multiple invoices assigned to it.

I am able to register the NF correctly, but does not show the customer number that this invoice is linked to, the BD appears id, nf number, date and value but does not appear the customer number to whom it belongs. / p>

The invoice number field appears in the customer record and the value is null .

Follow the files:
