經常在mybatis中使用<if test="aa != ‘值‘ ">的話 怎麽怎麽樣

那麽等於怎麽寫呢?

註意 要想使用 == 僅僅需要將雙引號和單引號的位置換一下即可!!!

<update id="updateGoodsShelf" parameterType="java.lang.String">
        update
        integral_goods
        set
        <if test=‘shelfFlag == "1"‘>
            shelf_flag = ${@com.pisen.cloud.luna.ms.jifen.base.domain.IntegralGoods@SHELF_ON}
        
 
</if>
        <if test=‘shelfFlag == "0"‘>
            shelf_flag = ${@com.pisen.cloud.luna.ms.jifen.base.domain.IntegralGoods@SHELF_OFF}
        </if>
        where
        uid
        IN
        <foreach collection="list" item="item" index="index" open="(" separator="," close=")"
 
>
            #{item}
        </foreach>
    </update>
