急!!!关于hibernate+SQLserver

Question

我的hibernate.cfg.xml配置如下:<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
          "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
          "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"><!-- Generated by MyEclipse Hibernate Tools.                   -->

Answer 1

net.sf.hibernate.dialect.SQLServerDialect 
===>
org.hibernate.dialect.SQLServerDialect

} else {
forward = "loginfailed";
}
request.getSession().setAttribute("empname", empname);

return mapping.findForward(forward);
}请前辈们 指点 小弟一下~~  无胜感激!!!

Answer 3

在你的hibernate.cfg.xml中加入下面的的语句试试:<property name="dialect">org.hibernate.dialect.SQLServerDialect</property>
产生这个错误的原因,可能你加入了自动键表的指令如:
<property name="hbm2ddl.auto">create</property>
或者是时候了hbm2java这样的自动生成工具时 ,如果不指令方言就会报错

Answer 4

Caused   by:   org.hibernate.MappingException:   Dialect   does   not   support   sequences 
写得这么清楚， 你就不会看两眼。
方言不支持序列。
序列是oracle才有的东西， 你的SqlService哪有这东西， 去改映射表的主键生成方式
