Answer 1

was not of the specified subclass: com.test.bean.employee.Employee (Discriminator: skiller )你有没有继承

Answer 2

没有指定的子类com.test.bean.employee.Employee，要么楼主没有继承，要么楼主没有写这个类

Answer 3

Employee,是个父类，IDE却把它当子类.........

Answer 4

 
  String HQL="from Employee";
  
  List list=(s.createQuery(HQL)).list();
  
  Iterator it=list.iterator();
  
  System.out.println(list.size());我查的是全部记录..
