添加方法：
public void add(Client client,Order order){
try{
session = HibernateUtil.getSession();
session.beginTransaction();
session.save(client);
// session.save(order);
session.beginTransaction().commit();
}finally{
if(session!=null){
session.close();
}
}
}
public void find(int id){
try{
session = HibernateUtil.getSession();
session.beginTransaction();
Client client = (Client) session.get(Order.class, id);
Set orders =client.getOrder();
orders.size();
session.beginTransaction().commit();
}finally{
if(session!=null){
session.close();
}
}
}
