<selectKey resultClass="int" keyProperty="id">    

<![CDATA[SELECT LAST_INSERT_ID() AS ID ]]> <!-- 该方法LAST_INSERT_ID()与数据库连接绑定，不会发生上述MS SQL Server的函数问题。 -->    

</selectKey>    

</insert>    

或推荐方式

<insert id="add" parameterType="vo.Category">

<selectKey resultType="java.lang.Short" type="POST" keyProperty="id">

SELECT LAST_INSERT_ID() AS id

</selectKey>

insert into category (name_zh, parent_id,

show_order, delete_status, description

)

values (#{nameZh,jdbcType=VARCHAR},

#{parentId,jdbcType=SMALLINT},

#{showOrder,jdbcType=SMALLINT},

#{deleteStatus,jdbcType=BIT},

#{description,jdbcType=VARCHAR}

)

</insert>
