Java Web学习笔记（总结）

1.注意必须有"new"才能赋值给admin。
public class AdminAction extends ActionSupport implements ModelDriven<Admin> {
    private Admin admin = new Admin();
    @Override
    public Admin getModel() {
       // TODO Auto-generated method stub
       return admin;
   }
}

2.注意hql语言中表名（Admin）为对象类名称，且区分大小写。
public Admin login(Admin admin) {
  // TODO Auto-generated method stub
  String hql = "FROM Admin WHERE username='" + admin.getUsername() + "'"
    + " AND password='" + admin.getPassword() + "'";
  @SuppressWarnings("unchecked")
  List<Admin> list = this.getHibernateTemplate().find(hql);
  if(list!=null&&list.size()>0) {
   return list.get(0);
  }
  return null;
 }
