Mybatis Plus foreach 嵌套 判断

话不多说直接上代码
gldjs 是List

<foreach collection="gldjs" item="gldj" open="(" close=")" index="index" separator="or">
    gldj = ${gldj}
    and exists(select 1
    from tb_fw_zfjc b
    where yxzt = '1'
    and a.syfw_id = b.syfw_id
    <choose>
        <when test="gldj == 1 ">
            and timestampdiff(day, jcrq, curdate()) > (30 - 3))
        </when>
        <when test="gldj == 2 ">
            and timestampdiff(day, jcrq, curdate()) > (90 - 7))
        </when>
        <when test="gldj == 3 ">
            and timestampdiff(day, jcrq, curdate()) > (365 - 15))
        </when>
    </choose>
</foreach>
