Do I understand correctly that if there are two entities with a One-to-Many relationship, such as Employee and EmployeePhones. Then you need to receive such data on the server in DTO with one call, but with two separate json? And write down one by one: first the employee, get the ID from the saved employee, and then we record the phones using this ID for communication.

Actually I think that on @ManyToOne fetch type is EAGER by default, so that means whenever you fetch Address it will fetch Employee in same query.
it is presented in console as well, as both system.out.println are presented one below another. Otherwise, it will be presented like: 1. query, 1. sysout, 2. query, 2. sysout

Nice way to do mapping if you do not want associative entities.
