<hibernate-mapping>
<class name="entity.Stu" table="stu" schema="dbo">
<id name="id" type="java.lang.Integer">
<column name="id" />
<generator class="identity" />
</id>
<property name="name" type="java.lang.String">
<column name="name" length="50" not-null="true" />
</property>
<property name="phone" type="java.lang.String">
<column name="phone" length="50" not-null="true" />
