【mybatis】mybatis中放置IN查询拼接sql过长，IN查询进行分批次查询的处理

 

需要使用的切割list集合的工具类，链接：https://www.cnblogs.com/sxdcgaq8080/p/9376947.html

处理逻辑，原本的一个LIst，进行切割，循环进行mybatis查询即可

 

举个例子：

mapper.xml中方法查询如下：

 <select
            id="dealFindByNameAndMobile"
            parameterType="com.pisen.cloud.luna.ms.dealer.base.mapper.bean.DealerBean"
            resultType="com.pisen.cloud.luna.ms.dealer.base.domain.Dealer">


        SELECT
        dea.id id,
        dea.uid uid,
        dea.enabled_flag enabledFlag,
        dea.delete_flag deleteFlag,
        dea.tenement_id tenementId,
        dea.parent_id parentId,
        dea.name name,
        dea.type type,
        dea.bar_code barCode,
        dea.outer_code outerCode,
        dea.outer_id outerId,
        dea.mne_code  mneCode,
        dea.address address,
        dea.address_xy addressXy,
        dea.business_area businessArea,
        dea.business_area_xy businessAreaXy

        FROM
        dealer AS dea
        LEFT JOIN  (SELECT a.* FROM contact AS a where  a.main_contact = ${@com.pisen.cloud.luna.ms.dealer.base.domain.Contact@IS_MAIN} AND a.delete_flag = ${@com.pisen.cloud.luna.ms.dealer.base.common.BaseDomain@DELETE_FLAG_NO} AND a.enabled_flag = ${@com.pisen.cloud.luna.ms.dealer.base.common.BaseDomain@ENABLED_FLAG_EN}) con ON dea.uid = con.dealer_id

        WHERE
        dea.delete_flag = ${@com.pisen.cloud.luna.ms.dealer.base.common.BaseDomain@DELETE_FLAG_NO}

        AND
        dea.enabled_flag = ${@com.pisen.cloud.luna.ms.dealer.base.common.BaseDomain@ENABLED_FLAG_EN}

        <if test="name != null and name != '' ">
            AND
            dea.name LIKE '%' #{name} '%'
        </if>

        AND
        dea.uid IN
        <foreach collection="uidList" open="(" close=")" separator="," item="item" index="index">
            #{item}
        </foreach>
