Field Based Persistence

Does field based persistence mean having annotated public entity variables without getters and setters?

I tried making annotated private entity instance variables and providing getters /setters. It works this way too. So I am now not sure what exactly is meant by field based persistence?

Hi nitin,

as you probably now that @Id annotation decides whether to use field or getter/setter based persistence management. If you use field based the members don't have to be public as the entity manager also has access to inject member values even if they are declared private.

I'd personally recommend using the getter/setter based approach though because this allows you to be more flexible if you want to do some additional things in your getter/setter which wouldn't be possible with direct field access.

It is sorta covered in the JavaRanch Style Guide.
