Can't start a cloned connection while in manual tran

?

在进行HQL查询是出现的错误：

使用iterate进行查询，代码如下，报出

Can't start a cloned connection while in manual transaction mode.

错误，

1. ????????????Iterator?iter?=?session.createQuery("from?Student").iterate();
2. ????????????while(iter.hasNext())?{
3. ????????????????Student?student?=?(Student)iter.next();
4. ????????????????System.out.println(student.getName());
5. ????????????}

但是使用，如下代码进行查询，却没有报错，

?

1. ????????????List?students?=?session.createQuery("from?Student").list();
2. ????????????for?(Iterator?iter=students.iterator();?iter.hasNext();)?{
3. ????????????????Student?student?=?(Student)iter.next();
4. ????????????????System.out.println(student.getName());
5. ????????????}
6. ????????????System.out.println("---------------------------------------------");
7. ????????????Iterator?iter?=?session.createQuery("from?Student").iterate();
8. ????????????while(iter.hasNext())?{
9. ????????????????Student?student?=?(Student)iter.next();
10. ????????????????System.out.println(student.getName());
11. ????????????}

找了相关资料，最后解决了问题，修改连接数据库的URL为

jdbc:microsoft:sqlserver://localhost:1433;DataBaseName=Hibernate_HQL;SelectMethod=cursor

在URL后加入红色标注代码
