QueryWrapper OR 的用法

@Data
public class ReimburseAwardQueryDTO extends PageQuery<ReimburseAwardDomain> {
    private static final long serialVersionUID = 1L;

    @ApiModelProperty("主键id")
    private Long id;

    @ApiModelProperty("手机号或账号")
    private String mobileOrUserName;

    @Override
    public QueryWrapper<ReimburseAwardDomain> toQueryWrapper() {
        QueryWrapper<ReimburseAwardDomain> queryWrapper = new QueryWrapper<>();
        //----------------条件开始-------------------

        queryWrapper.eq(valid(id),"id",id);
        /**或者条件*/
        if (valid(mobileOrUserName)) {
         queryWrapper.and(q -> q.eq("user_name", mobileOrUserName).or().eq("mobile",     mobileOrUserName).or().eq("real_name", mobileOrUserName));
        }
        //----------------排序倒序-------------------
        queryWrapper.orderByDesc("create_time").orderByDesc("id");
        super.addOrder(queryWrapper);
        return queryWrapper;
    }
}

用 queryWrapper.and(  )开始, and里面用.or().eq(条件)

相当于以下Mybatis SQL代码

    <select id="selectReimburseAwardList" parameterType="com.hq.admin.marketing.dto.ReimburseAwardQueryDTO">
        SELECT  <include refid="Base_Column_List" />
        FROM t_reimburse_award
        <where>
            id = #{id}
	    <if test="mobileOrUserName!='' ">
           AND (user_name = #{mobileOrUserName}	OR mobile = #{mobileOrUserName}	OR real_name = #{mobileOrUserName})
        </if>
        </where>
    ORDER BY create_time DESC, id DESC
    </select>
