动态sql 单选变多选

实体类

添加数组存储值

private ArrayList tssjfjList;

<!--            <if test="tssjfj != null  and tssjfj != ''">and tssjfj = #{tssjfj}</if>-->

            <if test="tssjfjList != null and tssjfjList.size() > 0">
                AND tssjfj IN
                <foreach item="item" index="index" collection="tssjfjList" open="(" separator="," close=")">
                    #{item}
                </foreach>
            </if>

存在循环且模糊匹配的情况

  <if test="corpbqList != null and corpbqList.size() > 0">
                AND (
                <foreach item="item" index="index" collection="corpbqList" open="(" separator=" OR " close=")">
                    typed LIKE CONCAT('%', #{item}::text, '%')
                </foreach>
                )
            </if>
