不知道是什么地方没有配置好能还是什么其它原因！thx

没有人帮我吗？顶一下！

db url中加上selectMode=cursor

我加上试试好像还是不行，报错信息一样的，我把我的配置代码也贴上，劳烦你们看看

hibernate.properties：

[code:1]
## MS SQL Server

hibernate.dialect net.sf.hibernate.dialect.SQLServerDialect
hibernate.connection.username sa
hibernate.connection.password 123456

## Microsoft Driver (not recommended!)
hibernate.connection.driver_class com.microsoft.jdbc.sqlserver.SQLServerDriver
hibernate.connection.url jdbc:microsoft:sqlserver://egov-server:1433;DatabaseName=test;SelectMethod=test
[/code:1]

hibernate.cfg.xml:

[code:1]

不知道是否是因为我的配置文件写的有问题，还是什么，我实在看不出来了

咋没有人嗫！

？？

先谢谢你的关注！
SelectMethod=×××我不太清楚这个有什么用？
另外我修改成你先前所说的selectMode=cursor，但好像问题依旧，现在搞的很郁闷。

sorry，是SelectMethod=cursor

OK!好了，原来是这个原因阿，再问一句SelectMethod=cursor
是什么意思，起什么作用的
