一开始的写法

SELECT
    rrc.id,
    rrc.resource_name
        rrc.is_publish
FROM
    res_resource_catalog AS rrc
<where>
<if test="keyWord != null and keyWord != ‘‘">
                AND rrc.resource_name LIKE concat(concat("%",#keyWord),"%") OR rrc.resource_abstract LIKE concat(concat("%",#keyWord),"%")
                OR rrc.id IN (SELECT DISTINCT resource_id FROM res_info_item WHERE item_name LIKE concat(concat("%",#keyWord),"%"))
            </if>
AND rrc.is_publish = 1
</where>

正确的写法:在<if>里面增加一对()

SELECT
    rrc.id,
    rrc.resource_name
        rrc.is_publish
FROM
    res_resource_catalog AS rrc
<where>
<if test="keyWord != null and keyWord != ‘‘">
                AND (rrc.resource_name LIKE concat(concat("%",#keyWord),"%") OR rrc.resource_abstract LIKE concat(concat("%",#keyWord),"%")
                OR rrc.id IN (SELECT DISTINCT resource_id FROM res_info_item WHERE item_name LIKE concat(concat("%",#keyWord),"%")))
            </if>
AND rrc.is_publish = 1
</where>
