急!!!关于hibernate+SQLserver

[rapelwill]

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. -->
<hibernate-configuration>
<session-factory>
<property name="connection.driver_class">
com.microsoft.jdbc.sqlserver.SQLServerDriver
</property>
<property name="connection.url">
jdbc:microsoft:sqlserver://localhost:1433;databaseName=HumanResources
</property>
<property name="dialect">
net.sf.hibernate.dialect.SQLServerDialect
</property>
<property name="connection.username">
sa
</property>
<property name="connection.password">
password
</property>
<property name="show_sql">
true
</property>

<mapping resource="com/iss/lax/mapping/sourceemp.hbm.xml" />
<mapping resource="com/iss/lax/mapping/sourcedep.hbm.xml" />

</session-factory>

</hibernate-configuration>

mssqlserver.jar;msutil.jar;msbase.jar 三个包,我也加到了classpath里.结果运行时,报如下错:

请大虾们告诉小弟到底错哪了?!急啊!!!!小弟搞了都快一通宵,问题还是没解决!!

[rapelwill]

我知道是报方言的问题,但就是不知道应该如何修改啊~~~

[rapelwill]

那个问题解决了,可是现在又报了个Session的错误!!

我的类 HibernateSessionFactory中的方法:

public static Session currentSession() throws HibernateException {

Session session = (Session) threadLocal.get();

if (session == null) {
if (sessionFactory == null) {
try {
cfg.configure(CONFIG_FILE_LOCATION);
sessionFactory = cfg.buildSessionFactory();
}
catch (Exception e) {
System.err.println("%%%% Error Creating SessionFactory %%%%");
e.printStackTrace();
}
}
session = sessionFactory.openSession();
threadLocal.set(session);
}

return session;

类 DbFunction 中的 在数据库中,找出符合从登陆窗口输入的用户名和编号,并计算是否等于1 的方法如下:

public int loginFindOut (String empname,int empnumber) {
Session session1 = HibernateSessionFactory.currentSession();
Transaction tx = session1.beginTransaction();
Query query1 = session1.createQuery(hql1);
query1.setString("empname", empname);
query1.setInteger("empnumber",empnumber);
Integer i = (Integer) query1.uniqueResult();
tx.commit();
HibernateSessionFactory.closeSession();
return i;
}

类 MyAction 中的登陆方法如下:
public ActionForward login(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
MyForm myform = (MyForm) form;
String empname = myform.getEmpname();
int empnumber = myform.getEmpnumber();
DbFunction db = new DbFunction ();
String forward = null;

if (db.loginFindOut(empname ,empnumber)==1 ) {
forward = "loginsuccessful";
} 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!!!

谁便谁 来说两句也好啊~~ 小弟急啊~~~

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

[sharpyuce]

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

[aChinese]

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
