        InsertManyResult insertManyResult = deviceCollection.insertMany(list);

                Projections.computed("date", new Document("$dateToParts", new Document().append("date", "$ts"))),

本插件不同于V5代码生成器插件，无须引入项目中其他jar包，无须事先编译POJO类：

• 插件不依赖任何第三方jar包
• 通过 POJO 类生成接口类、接口实现类、控制类
• IDEA 须从项目根目录打开加载项目(以获取正确的 projectBasePath )
• 打开 POJO 类Java文件，在文件内部右击选择”Generate”->”WkCodeGenerator”

燃气公司现状及痛点

• 燃气表品牌多、型号多、计费类型多，厂家附送系统各自独立且无法自动对账，导致账目误差时有出现，实际经营情况无法实时掌握。
• 物联网智能表具原来越多，物联网设备本身的安全监测是当前的核心问题，且因设备厂家、型号多样化，设备的统一接入、监控就尤为重要。
• 从市场拓展到客户服务无法全流程业务管控、联动和监督，导致物资储备、施工安排、工程监督等无法根据实际情况实时管控，用户开户、移表等服务无法高效响应和调度。

BudWk微服务解决方案

• IC卡表的统一集成

使用 WPF + CefSharp 技术，C/S客户端 + B/S浏览器的组合，利用客户端实现IC卡读写器的集成开发，实现IC卡表的读写功能，利用B/S浏览器，将营收系统嵌入浏览器，实现WEB营收业务代码热更新、数据统一管理等功能。

• 物联网表的统一集成

抽象设备接入层，实现电信AEP平台、移动OneNET、厂家物联网平台等平台接入，实现 NB-IOT/MQTT/HTTP 等协议的适配和转换，将各表厂繁杂不一的数据格式转换为本平台统一数据格式，并利用规则引擎技术，实现数据的智能化处理。

• 计费类型的统一集成

系统内置预付费、后付费、表端计费等计费类型，支持“购气/退气”和“充值/退费”等业务形态，支持阶梯计价、区域计价等价格规则。

• 工单系统的统一集成

燃气报装、报修、维修、安检等业务流程标准化、制度化，通过流程配置、节点配置、权限配置等，实现业务工单的动态分配和统一管理。

后端技术框架

采用 BudWk 国产微服务分布式架构，基于 nutzboot + dubbo + nacos + druid 技术体系，核心框架为国产开源框架 nutzboot，采用 Sa-Token权限系统及JWT。根据业务划分微服务模块，如：

• Sys – 系统及权限模块
• Cms – 内容及资讯模块
• Wx – 微信服务模块
• Dev – 物联网表接入模块
• Gas – 营收业务模块
• WebAPI – 后端服务API模块
• OpenAPI – 第三方服务API模块

前端技术框架

采用 Vite + Vue3 + ElementPlus 常用组合，前后端分离开发模式，封装集成多语言、路由、权限控制、文件上传等功能。

BudWk微服务分布式框架介绍

BudWk(原名NutzWk)发展自2010年，2012年开始用于商业项目，至今已服务于全国各地公司大大小小数千个项目，行业涉及政务、电商、物联网等，随着个人经验积累及从事行业的不同分别发布了1.x至8.x多个版本，您可以根据项目规模选择不同版本。本项目案例众多，省厅级项目、市级平台、大数据项目、电商平台、物联网平台等等。
