【mybatis】mybatis 中update 更新操做，null字段不更新，有值才更新

示例代码以下：

<update id="updateGoodsConfigQuery" parameterType="com.pisen.cloud.luna.ms.goods.base.common.UpdateGoodsQueryBean"> update goods_config_query <trim prefix="set" suffixOverrides=",">
            <if test="configQuery.innerFrist != null">inner_frist=#{configQuery.innerFrist},</if>
