mybatis like %%问题

<select id="getMaxNotOnlineInfoByConditon" resultType="com.shishike.susie.entity.CustomConfirmInfo">
 
SELECT *
FROM t_customconfirminfo
WHERE (if(#{pduName,jdbcType=VARCHAR} IS NULL, 0 = 0, pduname = #{pduName,jdbcType=VARCHAR})
   AND if(#{moduleName,jdbcType=VARCHAR} IS NULL, 0 = 0, modulename = #{moduleName,jdbcType=VARCHAR})
   AND if(#{env,jdbcType=VARCHAR} IS NULL, 0 = 0, confirminfo = #{env,jdbcType=VARCHAR})
   AND if(#{ossAddress,jdbcType=VARCHAR} IS NULL, 0 = 0, ossaddress = #{ossAddress,jdbcType=VARCHAR})
   AND if(#{branch,jdbcType=VARCHAR} IS NULL, 0 = 0,  branch like concat(concat('%',#{branch,jdbcType=VARCHAR}),'%'))
   AND if(#{confirmId,jdbcType=BIGINT} IS NULL, 0 = 0, id > #{confirmId,jdbcType=BIGINT})
   AND onlineinfo is null)
ORDER BY CREATED DESC
LIMIT 1
</select>

mybatis 关于like的处理

1、利用"%"对入参进行拼接

2、SQL语句字符串拼接

SELECT * FROM tableName WHERE name LIKE CONCAT(CONCAT('%', #{text}), '%');

3、bind标签

<select id="findUserByFuzzyEmail" resultMap="BaseResultMap"
        parameterType="java.lang.String">
        select id,username,email,status,createtime,updatetime from tb_user
        <bind name="pattern" value="'%'+_parameter.getEmail() +'%'" />
        <where>
            <if test="email != null and email != ''">
                email like #{pattern}
            </if>
        </where>
    </select>
