hibernate的问题请教

我的表是person
表的定义
CREATE TABLE [dbo].[person] (
[id] [int] IDENTITY (1, 1) NOT NULL ,
[name] [char] (6) COLLATE Chinese_PRC_CI_AS NULL ,
[address] [char] (10) COLLATE Chinese_PRC_CI_AS NULL
) ON [PRIMARY]
GO
ALTER TABLE [dbo].[person] WITH NOCHECK ADD
CONSTRAINT [PK_person] PRIMARY KEY CLUSTERED
([id]
) ON [PRIMARY]
GO

person.hbm.xml的内容如下：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 2.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd">
<hibernate-mapping>
<class name="com.demo.struts.dao.person" table="person">
<id column="id" length="32" name="id" type="int">
<generator class="uuid.hex"/>
</id>
<property column="name" length="6" name="name" not-null="true" type="string" unique="true"/>
<property column="address" length="10" name="address" not-null="true" type="string"/>
</class>
</hibernate-mapping>

测试servlet向该表插入一条数据

。。。
person psn = new person();
psn.setname("lance");
psn.setaddress("shanghai");
session.save(psn);
。。。

servlet执行并未出错，只是说插入失败
tomcat控制台显示的信息如下：
。。。

好像问题就出在id字段上，该怎么改呢？
