Answer 1

我昨天也出现上边的问题了。不知道为什么呀.
现在用private static final SessionFactory sessionFactory; static {
try {
sessionFactory = new Configuration().configure().buildSessionFactory();
} catch (HibernateException ex) {
throw new RuntimeException("Exception building SessionFactory: " + ex.getMessage(), ex);
}
}
这个也出现上面的问题了。真是晕死了。

Answer 2

sessionFactory = (SessionFactory)new Configuration().configure().buildSessionFactory();
