为啥我没设置二级缓存也可以读出缓存

关于 JAVA 框架-Hibernate-二级缓存 的提问

public class TestHibernate {
    public static void main(String[] args) {
 
        SessionFactory sf = new Configuration().configure().buildSessionFactory();
 
        Session s = sf.openSession();
        s.beginTransaction();
        Category p1 = (Category) s.get(Category.class,1);
        Category p2 = (Category) s.get(Category.class,1);
        s.getTransaction().commit();
        s.close();
        Session s2 = sf.openSession();
        s2.beginTransaction();
        Category p3 = (Category) s2.get(Category.class,1);
 
        s2.getTransaction().commit();
        s2.close();
        sf.close();
    }
}
