《OneCode開源低代碼引擎白皮書》部分對(duì)于OneCode功能及組成做了詳細(xì)的描述。本文根據(jù)BeeCode團(tuán)隊(duì)開放的內(nèi)測(cè)版實(shí)測(cè)，整理了技術(shù)揭秘系列，從產(chǎn)品的設(shè)計(jì)思想及技術(shù)原理方面來(lái)闡述以及平臺(tái)很對(duì)模型的賦能能力。本文主要針對(duì)的讀者是軟件專業(yè)領(lǐng)域的產(chǎn)品經(jīng)理、項(xiàng)目管理者、架構(gòu)師、程序員，如果您第一次閱讀本文需要優(yōu)先閱讀 《OneCode開源低代碼引擎白皮書》以方便對(duì)本文的理解。

一，OneCode 頂層設(shè)計(jì)

OneCode由三塊自成體系的可獨(dú)立部署運(yùn)行的部分組成。前端引擎負(fù)責(zé)界面建模并按低代碼協(xié)議協(xié)議生成標(biāo)準(zhǔn)JSON，中后臺(tái)OneCode通過(guò)讀取標(biāo)準(zhǔn)JSON協(xié)議，完成后端的視圖建模，合并DSM后端服務(wù)建模系統(tǒng)，完成完整的后端服務(wù)建模應(yīng)用，通過(guò)代碼工程完成前后端一體的出碼應(yīng)用。JDSCloud是OneCode的協(xié)同支撐系統(tǒng)，除了常規(guī)的資源代碼空間管理外，提供了獨(dú)立的沙箱運(yùn)行環(huán)境。為OneCode 提供工程化的仿真版本Ops等服務(wù)。

二，OneCode 建模過(guò)程

（1） 建模原理

用戶通過(guò)，拖拽完成頁(yè)面建模序列化為按標(biāo)準(zhǔn)協(xié)議序列化JSON文件,后端OneCode服務(wù)支撐系統(tǒng)解析JSON文件并混合DSM建模信息以及后端服務(wù)邏輯后，通過(guò)混合編譯，通過(guò)代碼工廠指定出碼模板，完成前后端一體的編譯文件。

（1）拖拽建模

用戶由前端低代碼引擎提供拖拽支持，將用戶需求轉(zhuǎn)換為相應(yīng)的組件組合，完成建模后根據(jù)標(biāo)準(zhǔn)的低代碼組件序列化為JSON文件。

標(biāo)準(zhǔn)組件協(xié)議描述方式

（2）后端融合

后端融合系統(tǒng)，通過(guò)讀取標(biāo)準(zhǔn)JSON組件，完成組件在后端的模型轉(zhuǎn)換。用戶可以通過(guò)，DSM模型工具或者通過(guò)OneCode提供的建模通訊SDK，針對(duì)前端需要的服務(wù)調(diào)用邏輯以及業(yè)務(wù)數(shù)據(jù)邏輯，進(jìn)行建模干預(yù)。

（3）混合編譯出碼

完成后端建模的融合后，通過(guò)代碼工廠通過(guò)出碼配置輸出為OneCode源碼。

三，OneCode編譯原理

OneCode 本身基于JAVA語(yǔ)言體系，是在Java Spring 注解基礎(chǔ)上的一套擴(kuò)展子集，混合編譯引擎器通過(guò)擴(kuò)展注解構(gòu)建完整的Domain模型，通過(guò)讀取標(biāo)準(zhǔn)Spring 注解完成普通Web數(shù)據(jù)交付及調(diào)度過(guò)程，通過(guò)Domin域模型動(dòng)態(tài)渲染JS文件輸出為JSON交付給前端引擎構(gòu)建頁(yè)面。

四，平臺(tái)賦能

（1）標(biāo)準(zhǔn)化能力

OneCode平臺(tái)在設(shè)計(jì)上將前端組件的設(shè)計(jì)上即采用了開放式設(shè)計(jì)模型及及存儲(chǔ)通訊標(biāo)準(zhǔn)。這將在很大程度上為各家低代碼平臺(tái)組件互聯(lián)互通提供便利，在設(shè)計(jì)上實(shí)現(xiàn)通用通行。避免形成應(yīng)用孤島。解決用戶被綁定在特定平臺(tái)的憂慮。

（2）混合編譯賦能

OneCode除了在前端實(shí)現(xiàn)了標(biāo)準(zhǔn)化組件定義外，還額外提供了后端建模的工具DSM，并通過(guò)領(lǐng)域模型將二者打通。這樣在前端組件建模時(shí)便可以直接調(diào)用后端服務(wù)模型完成數(shù)據(jù)部分API構(gòu)建。而DSM模型工具也可以在后端建模時(shí)直接讀取前端組件屬性，打通前端動(dòng)作與后端服務(wù)的通訊能力。

視圖設(shè)計(jì)器通過(guò)，后端模型綁定插件快速選定后端Agg聚合服務(wù)模型接口，配置頁(yè)面快速綁定前后臺(tái)交互

后端DSM建模通過(guò)視圖模型擴(kuò)展直接修改操作，前端組件模型

二者模型的打通大幅降低了低代碼平臺(tái)的勞動(dòng)強(qiáng)度，同時(shí)通過(guò)針對(duì)模型的建模干預(yù)API，在模型建立重構(gòu)的方面可以從更深的層次上建立業(yè)務(wù)模型的構(gòu)建能力。

（3）混編檢測(cè)（預(yù)編譯）

傳統(tǒng)低代碼平臺(tái)基本上都是完全建立在JS的模型下，在初期建模時(shí)結(jié)構(gòu)還算清晰但經(jīng)過(guò)稍有點(diǎn)復(fù)雜的邏輯，構(gòu)建時(shí)代碼的冗余度以及結(jié)構(gòu)就會(huì)變得混亂，特別是頁(yè)跨頁(yè)面操作或者完成前后臺(tái)數(shù)據(jù)交互時(shí)。由于其腳本語(yǔ)言的特點(diǎn)無(wú)法完成實(shí)時(shí)校驗(yàn)，只能運(yùn)行期測(cè)試才能發(fā)現(xiàn)問(wèn)題。采用低代碼構(gòu)建的頁(yè)面往往只是由于頁(yè)面中做了一些簡(jiǎn)單的組件增刪或者屬性樣式就該就會(huì)造成不可預(yù)期的結(jié)果，這大大降低了代碼的可維護(hù)度。OneCode所構(gòu)建的領(lǐng)域模型則很好的解決了這一問(wèn)題，在前后端任意模型發(fā)生變化時(shí)即可調(diào)用混合編譯，將頁(yè)面間的連接關(guān)系以及前后臺(tái)的數(shù)據(jù)關(guān)系進(jìn)行校驗(yàn)通知。在預(yù)編譯中提升整體的編譯能力。

（4）傳統(tǒng)低代碼服務(wù)賦能

在低代碼平臺(tái)有幾個(gè)領(lǐng)域是有很不錯(cuò)的實(shí)施效果的我們以最常見(jiàn)的表單流程模式來(lái)談一下OneCode賦能

流程 表單為核心應(yīng)用的BPM模式

用戶通過(guò)圖形界面繪制表單，然后通過(guò)自動(dòng)生成數(shù)據(jù)庫(kù)或者綁定特定數(shù)據(jù)庫(kù)字段完成數(shù)據(jù)，再配合流程引擎完成數(shù)據(jù)流轉(zhuǎn)。傳統(tǒng)方案的優(yōu)勢(shì)在于其通過(guò)簡(jiǎn)化數(shù)據(jù)模型即后臺(tái)提升了快速定制的能力。但其劣勢(shì)也很明顯，但流程數(shù)據(jù)只能自成體系的完成運(yùn)轉(zhuǎn)，一旦需要與外部系統(tǒng)交互只能通過(guò)代碼的二次開發(fā)來(lái)完成。而表單中如果需要嵌入外部數(shù)據(jù)源也必須要通過(guò)二次開發(fā)來(lái)處理。這就很大程度限制了其發(fā)展。

如果采用OneCode 可以在很大程度上可以緩和這個(gè)矛盾。采用OneCode模型后表單的后端模型能力將得到大幅提升，在流程定制過(guò)程中可以通過(guò)OneCode建模插件直接調(diào)用表單業(yè)務(wù)模型，動(dòng)態(tài)修改表單組件屬性，實(shí)現(xiàn)更高級(jí)別更細(xì)力度的展現(xiàn)控制。同時(shí)OneCode表單在建模時(shí)也可以同步調(diào)用流程模型，實(shí)時(shí)根據(jù)流轉(zhuǎn)邏輯完成相應(yīng)相應(yīng)。

（5）運(yùn)行期動(dòng)態(tài)渲染

傳統(tǒng)低代碼平臺(tái)多數(shù)采用的是靜態(tài)的渲染模型 ，一旦完成頁(yè)面定義后，同一個(gè)頁(yè)面只能有一種展現(xiàn)和渲染結(jié)果，這些在普通的互聯(lián)網(wǎng)應(yīng)用中一般能滿足需求，但在企業(yè)應(yīng)用中，特別是一些權(quán)限模型比較復(fù)雜系統(tǒng)中。將權(quán)限模型混合到頁(yè)面中就會(huì)讓組件的特性變得一團(tuán)糟。而動(dòng)態(tài)運(yùn)算權(quán)限動(dòng)態(tài)繪制則更是突破了普通低代碼模型極限。

OneCode 則很好的彌補(bǔ)了這一遺憾，OnCode 在后端模型上提供了非常優(yōu)良的動(dòng)態(tài)API。

//系統(tǒng)單元測(cè)試中的 調(diào)用代碼示例。

@RequestMapping(value = "/test/")public class TestService { @RequestMapping(value = "DynTestList") @DynLoadAnnotation(refClassName = "test.Search")// @DialogAnnotation @ModuleAnnotation(dynLoad = true)//表示頁(yè)面加載為動(dòng)態(tài)頁(yè)面 @ResponseBody public ResultModel<EUModule> getTestList(EUModule module) { //注入動(dòng)態(tài)參數(shù) ResultModel resultModel = new ResultModel(); //添加一個(gè)JS方法到頁(yè)面 module.getComponent().getCustomFunctions().put("test", "function(){}"); //查找所有輸入域組件設(shè)為只讀 List<InputComponent> components= module.getComponent().findComponents(ComponentType.Input,"%%"); for(InputComponent<InputProperties,InputEventEnum> component:components){ component.getProperties().setReadonly(true); } resultModel.setData(module); return resultModel; }}

五，內(nèi)測(cè)系統(tǒng)示例揭秘

OneCode 這次首先發(fā)布了一個(gè)內(nèi)側(cè)版本，內(nèi)側(cè)版本中提供了相對(duì)比較詳細(xì)的，OneCode 示例和源碼。

從目錄上看涵蓋了，示例的組織機(jī)構(gòu)代碼、流程代碼等等大家常用的建模源碼。

由于篇幅關(guān)系，詳細(xì)的內(nèi)測(cè)版本源代碼編譯說(shuō)明會(huì)在后續(xù)發(fā)布。

大家有興趣可以回復(fù)獲取郵箱，獲取體驗(yàn)版版賬號(hào)及編譯說(shuō)明。
