The entity class should have a no-argument constructor. Both Hibernate and Jakarta Persistence require this.
|
||||
|
||||
Jakarta Persistence requires that this constructor be defined as public or protected.
|
||||
Hibernate, for the most part, does not care about the constructor visibility, as long as the system SecurityManager allows overriding the visibility setting.
|
||||
Hibernate, for the most part, does not care about the constructor visibility, and will override the visibility setting.
|
||||
That said, the constructor should be defined with at least package visibility if you wish to leverage runtime proxy generation.
