Quando utilizamos JPA com Hibernate como implementação. Como funciona a estratégia de geração de Ids AUTO? code example

Example: jpa generationtype sequence mysql

In Dec 2020, you still can’t use this strategy (SEQUENCE) with a MySQL database. 
It requires a database sequence, and MySQL doesn’t support this feature.

If you’re working with a MySQL database, you should always use 
GenerationType.IDENTITY. It uses an autoincremented database column and 
is the most efficient approach available. You can do that by annotating 
your primary key attribute with 
@GeneratedValue(strategy = GenerationType.IDENTITY).
