批量添加：
<insert id="insertBatch" parameterType="java.util.List" useGeneratedKeys="true">
insert into sys_order_csn (order_id,csn)
values
<foreach collection="list" item="order" index="index" separator=",">
(#{order.orderId,jdbcType=VARCHAR},#{order.csn,jdbcType=VARCHAR})
</foreach>
</insert>批量更新：
<update id="updateBatch" parameterType="java.util.List">
<foreach collection="list" item="item" index="index" open="" close="" separator=";">
update sys_repair
<set>
<if test=" null != item.updateTime and '' != item.updateTime ">
update_time = #{item.updateTime,jdbcType=TIMESTAMP},
</if>
<if test="null != item.customerName and '' != item.customerName ">
customer_name = #{item.customerName,jdbcType=VARCHAR},
</if>
<if test="null != item.customerPhone and '' != item.customerPhone ">
customer_phone = #{item.customerPhone,jdbcType=VARCHAR},
</if>
<if test="null != item.customerAddress and '' != item.customerAddress ">
customer_address = #{item.customerAddress,jdbcType=VARCHAR},
</if>
<if test="null != item.customerFaultDetail and '' != item.customerFaultDetail ">
customer_fault_detail = #{item.customerFaultDetail,jdbcType=VARCHAR},
</if>
</set>
where repair_id = #{item.repairId,jdbcType=VARCHAR}
</foreach>
</update>可能不是高效率方案。
