Design And Implementation Of Community Fresh O2O Ordering System Based On Android

In recent years,with the rapid development of Internet technology and e-commerce,many companies have joined the electricity business platform.Fresh also appeared "Internet + electricity platform”sales model,and agricultural products become "the last blue ocean" for e-commerce.Coupled with the support policies brought by the country,it changed the dilemma to a certain extent.But the distribution of the "last mile" problem also exists.To a certain extent,the model based on the community 020 fresh sales model will be solve the above drawbacks.In this paper,it mainly studies the development of the community fresh 020 system based on Android Firstly,it introduces the research background and significance of this subject,analyzes the resent situation of development,and puts forward the goal of this study.Then the overall architecture of Android smart phone platform,as well as the advantages of Android application development are analyzed in details.And these lays a theoretical basis for the system programing.It also research on related technologies of J2EE and lightweight J2EE application development framework SSH Secondly,using the UML object-oriented analysis and design idea,we design and implement this system.This system consists of a mobile client and Java Web server composition,the client mainly realizes the functions of registering and login for users,front page fresh display,fresh product classification and detail display,shopping cart and so on.The server is realized using SSH framework,including functions of fresh management,fresh category management and orders management.The mobile client and Web server exchange data using JSON technology.The client network access is realized with Http Client,which is a Apache open source project.Finally,by analyzing the system function and performance test results,the function of this system meet the expected demand system and this is has a certain practical value.
