java beans: difference between persistent field and persistent property?

Question

I got the impression that if we use persistent fields, there is no need for getter methods since the entity manager references the instance variables directly. However, when I removed the getter and setter methods from an entity to have persistent fields, the values for the corresponding instance variable was not retrieved from the database!

Does that mean we must have getter and setter methods even though we have persistent fields?

Answer 1

If the entity class uses persistence, fields Persistence accesses the entity class instance variables directly at runtime.

While on persistence property, there is a getter and a setter method for each property.

What you said should have worked on hibernate.
