How to organize automatic recording in JPA?

Question

Java

Hello, I started to study web development in the java language, the task was to write an application without using frameworks, the question arose of how to use Hibernate and JPA to organize Writing to data so that when writing to one table where there is a one-to-many relationship, there was a record in another table n

For example we have a test table and a question table. how to make it so that when adding a test, new questions automatically fall into the table.

Thanks in advance!

Answer 1

Something like this:
@ManyToOne(cascade=CascadeType.PERSIST)

Answer 2

If there is data in the field that is marked as a relation, then JPA itself must save related entities, you just need to specify the links correctly.
