spring jpa #ManyToOne not generating foreign keys - mysql

Question

When I generate the tables it generates it ok, but JPA is not generating any FK.
When I tell mysql to show me what it did to create the table it shows the lack of the foreign key constraint. It only generates KEY and it is not adding the foreign key.
mysql> show create table view_display;

dtype varchar(31) NOT NULL,
id bigint(20) NOT NULL,
col int(11) NOT NULL,
