源代码已经完全开源，还望大神发现问题多多指点，在下感激不尽，怎么部署和安装环境我已经在后面描述清楚了，这个主要关键还是对接硬件，如果你要改写底层硬件的协议，你用C来对接已经接口，内置到相机中去，这样也可以解决掉不需要场端要架电脑的问题，省掉很多麻烦

/**
* <p>Use this builder to construct a {@link Gson} instance when you need to set configuration
* options other than the default. For {@link Gson} with default configuration, it is simpler to
* use {@code new Gson()}. {@code GsonBuilder} is best used by creating it, and then invoking its
* various configuration methods, and finally calling create.</p>
*
* <p>The following is an example shows how to use the {@code GsonBuilder} to construct a Gson
* instance:
*
* <pre>
* Gson gson = new GsonBuilder()
* .registerTypeAdapter(Id.class, new IdTypeAdapter())
* .enableComplexMapKeySerialization()
* .serializeNulls()
* .setDateFormat(DateFormat.LONG)
* .setFieldNamingPolicy(FieldNamingPolicy.UPPER_CAMEL_CASE)
* .setPrettyPrinting()
* .setVersion(1.0)
* .create();
* </pre></p>
*
* <p>NOTES:
* <ul>
* <li> the order of invocation of configuration methods does not matter.</li>
* <li> The default serialization of {@link Date} and its subclasses in Gson does
* not contain time-zone information. So, if you are using date/time instances,
* use {@code GsonBuilder} and its {@code setDateFormat} methods.</li>
* </ul>

* then be serialized as a {@link JsonObject}.
*
* <p>Below is an example:
* <pre> {@code
* Gson gson = new GsonBuilder()
* .register(Point.class, new MyPointTypeAdapter())
* .enableComplexMapKeySerialization()
* .create();
*
* Map<Point, String> original = new LinkedHashMap<Point, String>();

* {
* "(5,6)": "a",
* "(8,8)": "b"
* }
* }</pre>
*
* <h3>Maps as JSON arrays</h3>
* For this case, assume that a type adapter was NOT registered for some
* {@code Point} class, but rather the default Gson serialization is applied.
* In this case, some {@code new Point(2,3)} would serialize as {@code
* {"x":2,"y":5}}.
*
* <p>Given the assumption above, a {@code Map<Point, String>} will be
* serialize as an array of arrays (can be viewed as an entry set of pairs).
*
* <p>Below is an example of serializing complex types as JSON arrays:
* <pre> {@code
* Gson gson = new GsonBuilder()
* .enableComplexMapKeySerialization()
* .create();
*
* Map<Point, String> original = new LinkedHashMap<Point, String>();
* original.put(new Point(5, 6), "a");

* System.out.println(gson.toJson(original, type));

【技术架构】：
后端开发语言java，框架oauth2+springboot2+doubble2.7.3，数据库mysql/mongodb/redis，即时通讯底层框架netty4，安卓和ios均为原生开发，后台管理模板vue-typescript-admin-template,文件服务fastDFS，短信目前仅集成阿里云短信服务。为千万级数据而生，千万级用户无忧，目前真实用户40w无压力，大数据时代物联网必备
【开源情况】：
代码完全开源，不存在授权问题，完全自主原创，不存在任何后门，不使用任何第三方私有jar包，性能和安全完全自主可控，想怎么耍就这么耍，就是这么任性，后续更新的话本人会持续更新部署教程。代码专业规范，新手看得懂，高手喜欢用。本系统完全免费
【部署环境】：
目前仅测试linux环境一切正常，win环境没部署过，演示地址在本文章末尾
【关于作者】：
屌丝码农一枚，4年前曾就职于开发停车场系统的公司，发现目前国内该领域垄断，技术过于陈旧，没有一个规范，故个人用来接近1年的时间在业余时间开发出这种系统，现代化标准的互联网应用，定位大型物联网大数据云平台系统，存在不足之处还望多多提宝贵意见，让我们打破市场垄断，让物联网应用更好的服务生活社会
软件架构
一、技术构成简述 （一）编程语言与架构简述 1．开发语言 （1）服务端 服务端语言目前均采用java语言开发，jdk版本要求1.8+。开发框架为springboot2+dubbo，鉴权采用oauth2，DB操作框架Mybaits，即时通讯底层框架与协议netty4
（2）客户端 目前我们主要客户端分为三个场景，分别为安卓，ios，微信公众号。安卓与ios均为原生开发，H5页面web端框架为vue
（3）后台管理 后台管理前端框架采用的是主流的vue element admin(TypeScript版本)，分层清晰，官方文档完整，社区活跃
2．数据存储 （1）重要数据存储 重要数据均采用mysql进行存储，支持部署主从，大部分数据尽可能进行事务处理，确保数据容灾性
（2）一般数据存储 非重要性数据例如聊天内容，系统消息通知，广告等数据均存储于mongodb数据库中
（3）缓存数据存储 微小量缓存会存在mysql中，例如评论的前N条评论快照会超小量进行字段适当冗余，在提高存储性价比情况下大大提高数据的查询能力。其它大部分数据缓存均存储于redis数据中
3．性能与安全 （1）性能解决方案 架构与技术解决方案均为本团队一线5年开发经验总结，目前我们正在接触的项目真实用户40w+，毫无压力，我们系统采用的架构与技术均在仔细多方面综合考虑后多次调整，采用更加合理，性能更佳的模式与解决方案
（2）安全解决方案 所有请求均需携带jwt串token进行访问，每个接口服务和管理服务均需配置公钥文件且具有jwt串token合法性校验能力，用户权限服务携带私钥文件负责密钥生成
4．架构与生命力 （1）采用架构 本系统采用阿里巴巴微服务框架dubbo来进行实现微服务提供能力，追求高性能，高可用，超细粒度独立微服务，相同服务可以动态灵活增加与减少，支持不停机发布新版本服务。每个服务之间均为独立存在，互不影响。例如短信发送，支付，订单，停车场系统接口，停车场后台管理，停车场提供者服务等均为独立的服务。
（2）架构潜力 整个系统众多服务分工明确，细粒度微服务，实现真正的插拔服务，功能的删减或停用，新增等均可在不破坏和入侵原来系统的前提下满足新的开发需求
5．二次开发说明 （1）适用客户对象 ①本身有互联网it编程技术和经验或者拥有技术团队的。 ②不具备第一个条件但是费用预算比较充足，二次开发需求少或者愿意支付高额定制费的 （2）团队要求 服务器运维，安卓与ios开发者，web前端开发者，java实际开发经验2年+开发者
（3）技术要求 过硬的java编程能力，网络编程能力，数据库设计与优化能力，架构设计能力，微服务思维能力，成熟的前端技术开发能力，中大型系统部署与运营能力
（4）硬件要求 Linux操作系统，4核8G(最低)5M带宽，可多台服务器中的微服务指向统一微服务调度中心(本系统微服务调度中心管理平台zookeeper)
（二）软件与硬件数据交互简述 1．硬件端 （1）目前解决方案 封装工具类，兼容市场主流硬件设备，只负责各类硬件数据封装为统一数据结构。硬件发包目前多为http主动推送数据，被动接受服务端返回指令
（2）未来解决方案 改造主流厂商硬件底层服务系统，新增硬件规范的合法身份数据，采用长连接进行数据交互，保证数据与指令的实时性与可靠性得到更好的保障
2．服务端 （1）被动处理硬件数据 中间件处理各类前端数据，接收硬件推送数据，解析，计算，做出相应反馈
（2）主动通知硬件发生事件行为 长连接推送指令，例如开闸，实时动态配置硬件数据等，
二、常规功能简述 （一）基础功能 1．硬件管理 支持单个硬件管理与记录，硬件在线状态，维修与进度记录等。与指定停车场出入口进行绑定，均有记录GPS位置
2．停车场管理 不同时段费用配置，每日封顶因素综合参与动态计费，也支持静态+每日上限计费。支持查询附近停车场功能
3．停车记录管理 详细记录产生时间，地点，进出口位置，进出时间，异常数据实时推送与快速处理
4．支付机构管理 每个停车场的支付账号均可以独立配置，支持同一个停车场使用多家支付机构进行支付，例如支付宝，微信，银联等。
5．支付与优惠活动管理 支付宝与微信，银联都均支持免密支付(无感支付)。本系统自带优惠券功能，支持支持多种套餐自定义与用户进行快捷手机上下单随时购买
（二）特色功能 1．异常数据实时推送，汇报，及时处理，提前预知与通知 2．即时通讯功能(IM聊天沟通) 性能，架构，优化等均参考微信聊天功能机制进行开发
3．行业好友与圈子 让该应用不止只能停车，还能交到志同道合的行业知音，让应用更有温度
