Design And Implementation Of Green Agricultural Products Online Trading And Service System Based On J2EE

With the rapid growth of the science and technology,human being has been step into the information society.In information society,Information which is the foundation of the society plays the leading role in the national economy. Microcomputer,microelectronics and communications revolution is the source power of society informatization.In our country's 5 years development program,it has been pointed out that china will strengthen the information technology research,using information technology to stimulate industrialization and traditional industries upgrade.Information technology is the focal point of economy,military,science and politics,it is the basis of the national security and continuous development,it is the representation of high technology,and it is the impetus of the related industry and whole national economy development.The development of information technology industry has brought a strong impact to the industry development,but also accelerated the process of modernization of manufacturing industries.Using modern information technology to informatization steps acceleration and industry structure upgrade will be very meaningful to the two fundamental changes and the four modernizations.Enterprise informatization takes advantage of the modern information technologies to make using of the information resource more efficiently and more deeply.Therefore improve enterprise production,management,operation,strategy, efficiency,economic benefit and marketing performance.As a matter of fact, enterprise informatization digitalizes Enterprise business,such as production process, material transportation,transaction process,cash flow and customer interaction,etc. Using the network information process resource to generate new information,making decision makers from different levels available to the information which will help them make the right decision to help enterprise resource optimal utilized.In this way the enterprise business will be more flexible and adapt to the changing competitive environment of market economy,to achieve the maximum economic benefits.Enterprise informatization could:first of all,improve the efficiency.It could significantly reduce the human resources,accelerate the speed of information processing and improve the information accuracy and reliability.Second,Improve economy performance.Through the assist management and assist decision-making system,enterprise could obtain the marketing information more accurate and timely, thereby get more marketing opportunities.Third,enhance the competitiveness of enterprises.It could greatly shorten the product design cycle,Improve product yield, improve the rapid Business-to-Market response ability,make the enterprise strategy more accurate and predictable,and greatly enhance the enterprise competitiveness.Mean while,accompany with the promotion of society informatization as well as the rapid development of Internet applications,the e-business brings tremendous impact to the traditional business philosophy,making the society economic structure and business model changes dramatically.Business model is no longer confined to the operational channel mode and shop management mode,internet sales,the brand new sales mode,has gradually accepted by the public and brings great challenge to the traditional modes.To enterprise,internet sales could reduce the channel and shop management costs and more benefit will deliver to the customer.At the same time,a good sales portal could greatly enhance the enterprise image.To customer,internet sales brings more convenience,they could buy what they desired in home with more economic prices.It can be predicted that online transactions will become an important 21st century business means.In our country,electronic,electrical,books and other Internet trading is booming,but the agricultural products internet sales is still in its infancy.The agricultural products internet sales are facing great opportunities and challenges.This thesis is based on the project of Jilin green Industry Corporation,names Jilin Green Product Corporation e-business and enterprise information service system. The system mainly includes the following two sub-systems.The first is design and implementation of the B2C e-business sales platform subsystem.The second is design and implementation of the enterprise information service system.The B2C e-business sales platform is developed with J2EE lightweight framework Struts,Hibernate and Ajax.The e-business sales platform mainly comprises user register and logon module, merchandise browse and search module,order management module,customer feedback module,customer evaluation module,merchandise picture browse module and backstage management module.The sales platform support multi-lingual,the JSP pages developed with Ajax was very friendly to the end users.Enhance the platform performance by optimizing Hibernate,Multi-level error-handling mechanism ensure the platform robustness.General business framework implement the dynamic role distribution,the user roles and privileges was preserved in the database.After the user logged in,the framework only shows the user with the specific role with the services that in their privileges.The developers could set aside the concept of user rights, Focus on business process implementation,enhance the development of efficient and effective,Shorten the software development cycle And has good scalability.The enterprise information service system includes a business information general framework and some functional modules developed on it,such as information management module,system account management module,storage management module,transportation management module,achievement management module,sales distribution management module and operational support module,etc.The project was developed using the lightweight J2EE mainstream framework, Struts and Hibernate.The struts framework introduces the MVC design pattern and divided the Java Web application to three layers,Model,View and Control.Using struts framework could simplify Web application development process,improve development efficiency,shorten the development cycle,and improve software maintainability and reusability.Hibernate framework introduces Object-Relation Mapping to the project,set up the mapping from Object-Oriented language to the relational database.Physical layer(Database layer) is separated from business model layer,not only makes the business logic clearer,but also reduces the workload of the persistent programming.In order to make the B2C internet sales platform more interactivity,some logic was developed using AJAX to interact with the server asynchronously.
