新手正在学习用hibernate做简单的sql增删改查操作，已经实现了增加，可是查询编号的时候出了问题，求大神们帮忙看一下，谢谢了
Session session = null;
Configuration conf = null;
SessionFactory sf = null;
Transaction tx=null;
news n = null;
try{
conf=new Configuration().configure();
sf=conf.buildSessionFactory();
session=sf.openSession();
tx = session.beginTransaction();
n = (news) session.load(news.class, new Byte("5"));
session.delete(n);
tx.commit();
}catch(HibernateException ex){
ex.printStackTrace();
tx.rollback();
}finally{
if(session!=null){
session.close();
}

}

这个是报错 org.hibernate.TypeMismatchException: Provided id of the wrong type for class entity.news. Expected: class java.lang.Integer, got class java.lang.Byte at org.hibernate.event.def.DefaultLoadEventListener.onLoad(DefaultLoadEventListener.java:109) at org.hibernate.impl.SessionImpl.fireLoad(SessionImpl.java:906) at org.hibernate.impl.SessionImpl.load(SessionImpl.java:823) at org.hibernate.impl.SessionImpl.load(SessionImpl.java:816) at test.main(test.java:30)

id 类型是integer 不是byte

[阳光越来越暖]

n = (news) session.load(news.class, new Byte("5")); 类名首字母大写 不应该是 n = (News) session.load(News.class, 5);

那个错不已经告诉你了，id有问题呗
