看了半天才发现，原来是映射文件中的主键生成方式有问题

<hibernate-mapping>
    <class name="xiayu.com.vo.User" table="user" catalog="xy">
        <id name="merId" type="java.lang.Integer">
            <column name="merId" />
            <generator class="sequence" />
        </id>
        <many-to-one name="dept" class="xiayu.com.vo.Dept" fetch="select">
            <column name="deptId" />
        </many-to-one>
        <property name="merName" type="java.lang.String">
            <column name="merName" length="20" />
        </property>
        <property name="merPwd" type="java.lang.String">
            <column name="merPwd" length="20" />
        </property>
    </class>
</hibernate-mapping>
