无状态会话bean中的静态字段

Question

If I have a static fields in a stateless bean :

@Stateless
@Local(SomeClass.class)
public class AccountBean implements SomeClass{

   private static final int STATIC_FIELD = 0;

   public AccountBean () {}
}

Will the STATIC_FIELD value be shared in all AccountBean instances, like in basic classes?

EDIT Mark the field as final as suggested bellow.

Answer 1

Yes, it will be shared, but only inside a single JVM of course. And its capitalization indicates that it's a constant, and should thus be final .

If it's not a constant, then it smells, doesn't respect tha Java naming conventions, and violates the EJB spec.
