测试类源码:
package ch03.hibernate;
import org.hibernate.*;
import org.hibernate.cfg.*;
public class Test {
public static void main(String[] args) {
try {
SessionFactory sf = new Configuration().configure().buildSessionFactory();
Session session = sf.openSession();
Transaction tx = session.beginTransaction();
UserName user = new UserName();
user.setUsername( "Hibernate ");
user.setPassword( "Fra22 ");
session.save(user);
session.save(user);
tx.commit();
session.close();
} catch (HibernateException e) {
e.printStackTrace();
}
}
}

麻烦各位看下,是什么原因!
------解决方案--------------------
log4j:WARN Please initialize the log4j system properly.
org.hibernate.HibernateException: /hibernate.cfg.xml not found
根据提示信息，没找到配置文件，可能是路径没设置正确吧。
------解决方案--------------------
你的log4j.properties没有配置。
它应该放在WEB-INF目录里面。修改里面的配置信息
classpath下log4j.xml配置错误
log4j.property和log4j.xml配置一下
