Initializing sleep mail

Question

I would like to initialize the members of the persistent object class as soon as Hibernate loads the object from the database.

How can i do this?

In particular: in the next stored object, I would like to initialize the datetime zone

class Schedule {

    Calendar date
    TimeZone tz;

}

I cannot do this in the constructor because hibernate will use setters to initialize the object. I cannot do this in setters because I cannot rely on the initialization order.

Answer 1

You need to register an event listener after loading; it will be called after loading the object so that you can perform any subsequent processing.

JPA (Hibernate EntityManager), @PostLoad.

Hibernate PostLoadEventListener .
