Hibernate出错java.lang.Error: Unresolved compilation problem:

Question

import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

public class HibernateUtils {
    public static SessionFactory sessionFactory;
     static{
         Configuration configuration=new Configuration().configure();
         sessionFactory=configuration.buildSessionFactory();
     }
    public static SessionFactory getSessionFactory() {      
        return sessionFactory;
    }

}

再调用它

SessionFactory sessionFactory=HibernateUtils.getSessionFactory();

报错
java.lang.Error: Unresolved compilation problem:
Cannot make a static reference to the non-static method getSessionFactory() from the type HibernateUtils，
是哪儿错了，求分析

Answer 1

public static SessionFactory sessionFactory; 将static去掉
