Answer 1

你是用strtus和hibernate结合的。HibernateUtil类里的初始化方法有问题吧，HibernateUtil.java32行看看是什么代码贴出来。

Answer 2

HibernateUtil.javapublic class HibernateUtil {

private static final SessionFactory sessionFactory;

static {
try {
sessionFactory = new Configuration().configure().buildSessionFactory();
}
catch(Throwable ex) {
throw new RuntimeException("Exception building SessionFactory: " + ex.getMessage(), ex);
}
}

public static final ThreadLocal session = new ThreadLocal();

public static Session currentSession() throws HibernateException {
Session s = (Session) session.get();
if(s == null) {
s = sessionFactory.openSession();
session.set(s);
}
return s;
}

public static void closeSession() throws HibernateException {
Session s = (Session) session.get();
session.set(null);
if(s != null) {
s.close();
}
}
}

Answer 3

hibernate.cfg.xml
Cat.hbm.xml
放的路径对吗?
