急着去夜跑，简单记录下，看代码

Mpper对象：

   /**
     * 条件查询
     * @param qo qo
     * @param userId userId
     * @return list
     */
    List<Customer> getCustomerList(@Param("qo") CustomerQO qo, @Param("userId")String userId);

xml文件：

   <!-- 查询有效客户 -->
    <select id="getCustomerList" parameterType="com.cyipp.skywalker.domain.qo.CustomerQO"
            resultType="com.cyipp.skywalker.domain.po.Customer">
        SELECT
        <include refid="customerColumns"/>
        FROM
        customer
        WHERE
        status = 1 and
        IF(1 in (SELECT role_id FROM sys_role_account WHERE user_id = #{userId}), 1 = 1, manager = #{userId})
        <if test="qo.level != null">
            and level = #{qo.level}
        </if>
        <if test="qo.name != null and qo.name !=''">
            and name = #{qo.name}
        </if>
        <if test="qo.brands != null and qo.brands !=''">
            and find_in_set(#{qo.brands},brands)>0
        </if>
        order by create_time desc
    </select>
