        //每页短信数量，根据实际情况进行调整
        int pageSize = 5;
        //总页数
        int pageCount = (int) Math.ceil((double) allMobileList.size() / pageSize);
        System.out.println("总页数^^pageCount：" + pageCount);
        for (int page = 1; page <= pageCount; page++) {
            System.out.println("当前是第 " + page + " 页发送");
            List<String> pageMobileList = allMobileList.subList(pageSize * (page - 1), Math.min(pageSize * page, allMobileList.size()));
            System.out.println("pageMobileList：" + pageMobileList);
            System.out.println("--------------------------------------");
            //这里是封装好的批量发送短信接口，这个发送短信接口在工具类不能直接使用，在这里只是演示，可以在测试类或者在实际业务接口执行
            alibabaSmsService.sendBatchSms(pageMobileList, KaiHuiLeDeviceEnum.B2B_KHL_VISIT_DEVICE_B2B_SYSTEM_PC.getDeviceId(), KaiHuiLeSMSMobileCodeConstant.B2B_KHL_SMS_MOBILE_CODE_OR_NOTICE_TYPE_55, "127.0.0.1", map);
            //这里每次分页延迟一秒后执行发送
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }

}

控制台打印输出结果：
