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>

以上为个人经验，希望能给大家一个参考，也希望大家多多支持自由互联。如有错误或未考虑完全的地方，望不吝赐教。
