【摘要】：外賣作為人們?nèi)粘Ｉ畹母哳l次需求,急需互聯(lián)網(wǎng)思維來改造這個(gè)產(chǎn)業(yè),以便人們享受更好的外賣服務(wù),商家獲得額外的利潤,因此外賣O2O應(yīng)運(yùn)而生。外賣連接商戶與用戶,而我們這里主要描述用戶端的外賣解決方案。作為一個(gè)強(qiáng)地理位置屬性的業(yè)務(wù),通過手機(jī)尋找附近外賣是天然的需求。外賣的手機(jī)app與其他app有著截然不同的要求,我們面臨著地理位置體驗(yàn)、商家配送范圍的界定和活動(dòng)營銷推廣的問題。本文針對地理位置體驗(yàn)設(shè)計(jì)了一套可隨時(shí)熱切換、迅速降級的地圖方案,滿足了用戶使用場景中的地理位置需求。針對商家配送范圍,我們采用了在地圖上繪制多邊形的方案,并解決了相關(guān)判定用戶位置否在配送范圍內(nèi)的問題。針對活動(dòng)營銷這樣一個(gè)規(guī)則復(fù)雜多變的業(yè)務(wù)領(lǐng)域,設(shè)計(jì)了一套易于擴(kuò)展、高度靈活的方案。技術(shù)架構(gòu)上采用了mobile-shell、spring、ibatis框架,使用標(biāo)準(zhǔn)的三層結(jié)構(gòu),并在表示層使用了MVC模式的設(shè)計(jì)思想。系統(tǒng)深度結(jié)合了互聯(lián)網(wǎng)企業(yè)常用的中間件服務(wù),保證了系統(tǒng)的性能、可用性和擴(kuò)展性。本文方案亦可用于O2O其他業(yè)務(wù)領(lǐng)域。業(yè)務(wù)場景的相似性是可用的基礎(chǔ)；其次通過日常監(jiān)控?cái)?shù)據(jù)可以看到本系統(tǒng)的各個(gè)服務(wù)接口平均響應(yīng)時(shí)間保持在50ms內(nèi),性能高；可擴(kuò)展性好,可以迅速擴(kuò)展功能,添加業(yè)務(wù)平臺(tái)；完善的降級方案保證了系統(tǒng)99.99%的可用性。本文首先介紹了外賣背景,然后是項(xiàng)目開發(fā)過程中使用的各項(xiàng)技術(shù),主要是框架和中間件。緊接著明確了項(xiàng)目的需求并根據(jù)需求完成項(xiàng)目的設(shè)計(jì),需求的內(nèi)容包括功能性需求、非功能需求以及用例分析,設(shè)計(jì)內(nèi)容包括系統(tǒng)架構(gòu)設(shè)計(jì)和策略、數(shù)據(jù)庫設(shè)計(jì)等。之后,本文詳細(xì)介紹了系統(tǒng)各個(gè)模塊的具體實(shí)現(xiàn),對涉及的算法有詳細(xì)的描述。最后,總結(jié)了整個(gè)項(xiàng)目的不足和進(jìn)一步的展望。
[Abstract]:As a high frequency demand of people's daily life, takeout is in urgent need of Internet thinking to transform this industry so that people can enjoy better take-out service, and merchants get extra profits, so takeout O2O emerges as the times require. Takeout links merchants to users, and we mainly describe the client-side delivery solution here. As a strong geographical location of the business, through the mobile phone to find nearby takeout is a natural demand. The app of take-out mobile phone has very different requirements from other app. We are faced with the problems of geographical experience, the definition of distribution scope and the promotion of activities. In this paper, we design a map scheme which can be hot-switched and quickly degraded to meet the needs of the users in the scene. In view of the distribution range of the merchant, we adopt the scheme of drawing polygon on the map, and solve the problem of determining whether the user's position is in the distribution range. In view of the activity marketing which is a complex and changeable business field, a set of extensible and highly flexible scheme is designed. The mobile-shell,spring,ibatis framework is used in the technical architecture, the standard three-tier structure is used, and the design idea of MVC pattern is used in the presentation layer. The system deeply combines the middleware services commonly used by Internet enterprises, and ensures the performance, availability and expansibility of the system. This scheme can also be used in other business areas of O _ 2O. The similarity of business scenarios is the basis of availability; secondly, through the daily monitoring data, we can see that the average response time of each service interface of the system is kept in 50ms, the performance is high, the extensibility is good, the function can be expanded quickly, and the service platform can be added. The perfect demotion scheme ensures 99.99% availability of the system. This paper first introduces the take-out background, then the technologies used in the development of the project, mainly framework and middleware. Then the requirements of the project are defined and the design of the project is completed according to the requirements. The content of the requirements includes functional requirements, non-functional requirements and use case analysis. The design content includes system architecture design and strategy, database design and so on. Then, this paper introduces the implementation of each module in detail, and describes the algorithm involved in detail. At last, the deficiency of the whole project and further prospect are summarized.
