Question

hibernate list 问题

try{
session = HibernateUtil.currentSession();
Transaction tx = session.beginTransaction();
//t.stu_No,t.stu_name,t.stu_id,t.stu_sex,t.stu_grade,t.stu_gradeNo,t.stu_photo,t.stu_dpt,t.stu_date
String studentQuery = "select * from t_cet as t where t.stu_No=:stu_No and t.stu_id=:stu_id";
Query sqlQuery = session.createSQLQuery(studentQuery);
sqlQuery.setParameter("stu_No", stu_No);
sqlQuery.setParameter("stu_id", stu_id);
List list = sqlQuery.list();
Iterator ite = list.iterator();
if(ite.hasNext()){
student = (Student)ite.next();
}
//student = (Student)session.get(Student.class,stu_No);
tx.commit();
session.clear();
}catch(Exception ex){
这是异常，student是实体类，并有相关配置文件，可以存数据
Ljava.lang.Object; cannot be cast to com.domain.Student

Answer 1

就是你查询出来的数据并没有封装在student实体类里面 当你强制转换的时候就抛类型转换异常！！

Answer 2

检查一下 你的POJO类
