my java object has a field of type int . When I select information for the database with this object and field is null in the database I get "net.sf.hibernate.PropertyAccessException: exception setting property value with CGLIB (set hibernate.cglib.use_reflection_optimizer=false for more info) setter " . If I change the field in my object to Integer .. it works , obviously because an int cannot be null ? This is my guess . Is there any way to handle nulls or do I have to uses an Integer for the mapping

I may be wrong here, but I think that you have to either use Integer or update your null db columns to 0. Heck, you can't make in java

int x = null;

so, no reason to suppose that Hibernate should do that for you.

int cannot be null, check java basics... ,


Work with Integer for NUMBER fields that can be null
