1 Introduction
1.1 Research background and significance
With the continuous development of China's higher education, the scale of colleges and universities continues to expand. In this process, the social influence of the university is increasing day by day, and the campus, as an important carrier of education and cultural communication, is becoming more and more important to promote it. Therefore, how to effectively combine the university spirit with the campus culture is one of the urgent problems to be solved in our country's universities. University campus charity auction refers to a mode of realizing university charity activities through network technology. At present, some domestic scholars have begun to pay attention to this field and have achieved certain results, but most of them focus on the theoretical level and lack of practical application. This article attempts to explore university campus charity auctions from the perspective of "Internet +", in order to enrich my country's charity theory, promote the healthy and sustainable development of charity, and then enhance my country's overall comprehensive competitiveness, which has high practical significance.
1.2 Research Status
At present, there are relatively few relevant literatures on university charity auctions in China. This paper uses the methods of literature review, questionnaire survey and case analysis to investigate and study some domestic colleges and universities' charity auction activities in recent years. The results show that: In the past five years, with the changes in the socio-economic environment and the improvement of people's living standards, it has become a common trend for college students to participate in philanthropy. However, at present, the academic community does not pay enough attention to this field, and the results are scattered and lack of systematic research results, which will affect the in-depth development of follow-up research work. Therefore, it is necessary to systematically sort out the situation of domestic university charity auctions to lay a solid theoretical foundation for further in-depth research in the future. At the same time, it can also provide reference for other institutions. In addition, this article adopts the method of literature research and comparative analysis, by consulting a large number of relevant literature and materials, combined with its own actual research results, and comprehensively summarizes the charity auction activities carried out by Chinese universities in the past five years from five aspects, in order to provide further insights for future scholars. The study provides some beneficial enlightenment, and then promotes the healthy and orderly development of Chinese philanthropy, and realizes the goal of a harmonious society.
1.3 Paper Structure and Chapter Arrangement
The thesis will be arranged in layers, except for the abstract acknowledgments and references, the main text will also analyze the requirements of the website, explain the general design and implemented functions, and finally list some commissioning records. The main structure of the thesis is as follows:
Chapter One Introduction. The first chapter mainly introduces the background of the subject research, the status quo of system development and the research content and main work of this paper.
Chapter Two: System Requirements Analysis. The second chapter mainly conducts demand analysis from the aspects of system users and functions.
Chapter Three: System Design. The third chapter mainly carries on the function design to the system frame, the system function module, the database.

Chapter Five: System Testing. Chapter 5 mainly tests some interfaces of the system and tests the main functions
2 Analysis of University Campus Charity Auction Websites
System analysis is a prerequisite for developing a project. Through system analysis, the basic needs of the main users of the system can be well understood, and this is also the reason for the development of the project. Further, feasibility analysis is carried out on system development, usually including technical feasibility, economic feasibility, etc. Feasibility analysis is also an analysis from the overall perspective of the project. Then it is to analyze the specific needs of the project, and the means of analysis are generally realized through the user's use case diagram. The following is a detailed introduction.
2.1 Feasibility analysis
Most of the tools used in the project are currently popular open source and free, so in the early stage of development, the funds used for the project will be greatly reduced, and the development of the software will not be affected by the funds during the project start-up period, so It is still economically feasible. Try to use the least cost to meet the needs of users. Save funds for labor costs and equipment costs. It will go further and further on the road of paperless and high efficiency.
So there is no question of economic viability.
(2) Operation feasibility:
The design of this project refers to several development cases of websites under this mode, analyzes their operation interface, combines many cases together, and highlights the people-oriented and simplified operation, so people with basic computer knowledge can operate this project.
Therefore, there is no problem with operability.
(3) Technical feasibility:
Technical feasibility refers to the feasibility of building a framework, and the acceptability of system technology upgrades when better technologies emerge, and the ratio of development time to cost.
The existing Java technology can cater to the construction of all e-commerce systems. When developing this university campus charity auction website, I used Java+MYSQL to run the overall program.
In summary, there is no problem with the technical feasibility.
(4) Legal feasibility:
From the perspective of developers, Java and MYSQL are open source and free online, and there will be no legal disputes in terms of intellectual property rights.
From the perspective of user use, as long as no contraband is sold on the system, a treaty agreement is made on the system, and illegal payments are eliminated.
In summary, there is no question of legal feasibility.
The business process is to use some specific symbols and lines to demonstrate the user's process of using the system. When performing system analysis, the business process can help developers better understand the business, find errors, and improve the system.
After the user successfully logs in to the system , the operation of adding data can be realized. The number of adding data is specific and generated by the system, and the user cannot fill it in at will. Except for the number, the user can fill in other additional information by himself, and the filled information is verified by the system and verified to be legal. Passing shows that the data addition is successful. On the contrary, the addition is not successful. Figure 2-1 shows the process of adding data.
Figure 2-1 Flowchart of adding data
2.2.2 Data modification process
The process of data modification is similar to the process of data addition described above, as shown in Figure 2-2 .
Figure 2-2 Data modification flow chart
If there are some useless data in the system , the relevant management personnel can also delete these data. Figure 2-3 is the flow chart of data deletion.
Figure 2-3 Data deletion flow chart
2.3 System function analysis
According to the role of the university campus charity auction website, I divided it into two parts: the registered user management module and the administrator management module.

(4) Tieba : On the navigation bar of the homepage, we will see the menu " Tieba ". After we click to enter, we will see the content of all the postbars posted by the administrator in the background, and we can like the Tieba we like . If If you want to find this information faster next time, you can also bookmark and comment;
(5) Item Auction : On the homepage navigation bar, we will see the menu " Item Auction ". After we click to enter, we will see all the item information released by the administrator in the background . We choose to know the price of the auction Information , you can increase the price + comment ;
(6) My Favorites: Under "My", you can view and manage the "My Favorites" information, you can view the favorites, and you can also delete the favorite information;
(6) My account: When the user clicks the "My" button in the upper right corner, a submenu will appear, click "My Account" to set the personal information and the password to log in to the system;
(7) Personal Center: When the user clicks the "My" button in the upper right corner, he will enter the corresponding background for information management;
Administrator management module:
(1) Login: The account of the administrator is directly set and generated in the data table, and no registration is required;
(2) Public point management: When you click on the " Public Management" menu, two sub-menus will appear, carousel map + bulletin board, and you can add, delete, modify and query these two modules;
(3) User management: When you click on the "User Management" menu, three sub-menus will appear: administrator + doctor user + ordinary user , and you can add, delete, modify and query these three
(4) System content management: When clicking on the " System Content Management" menu, two sub-menus will appear : post bar management + post bar classification , and at the same time, add, delete, modify and check the charity auctions displayed on the front desk ;
(5) System module management: When you click on the " System Module " menu, there will be auction results, theme classification, item classification, charity auction, donated items, item auction, item auction records, charity auction records, charity publicity, etc. Nine sub-menus, the administrator can add, delete, modify and query these nine modules;
2.3.2 Non-functional analysis
The non-functional requirements of the university campus charity auction website, such as the security, reliability, performance, and scalability of the university campus charity auction website. Specifically, it can be expressed in the following table 3-1:
Table 3- 1 Non-functional Requirements Table of University Campus Charity Auction Website

It also provides a standard for the code implementation and testing of charity auction websites on university campuses.
3 General Design of University Campus Charity Auction Website
This chapter mainly discusses the functional module design and database system design of the university campus charity auction website.
3.1 System architecture design
The campus charity auction website of this university is divided into three layers from the structure: presentation layer (UI), business logic layer (BLL) and data layer (DL).
Figure 3-1 System Architecture Design of University Campus Charity Auction Website
Presentation layer (UI): Also known as the UI layer, it mainly completes the UI interaction function of the university campus charity auction website. A good UI can improve the user experience of users and enhance the comfort of users when using the university campus charity auction website . The UI interface design should also adapt to different versions of the university campus charity auction website and different resolutions to achieve good compatibility. The requirements for UI interaction functions are reasonable, and users must obtain consistent interaction results when performing interactive operations, which requires a good connection between the presentation layer and the business logic layer.
Business logic layer (BLL): It mainly completes the data processing function of the university campus charity auction website. The data transmitted by the user from the presentation layer is processed and delivered to the data layer through the business logic layer, and the data read by the system from the data layer is processed and delivered to the presentation layer through the business logic layer.
Data layer (DL): Since the data of the university’s campus charity auction website is placed in the mysql database on the server side, the part that belongs to the service layer can be directly integrated into the business logic layer, so there is only a database in the data layer, which mainly completes The data storage and management functions of this university campus charity auction website.
3.2 System function module design
3.2.1 Overall functional module design
In the previous chapter, the functional requirements and non-functional requirements of the system were mainly analyzed, and the use cases in the university campus charity auction website were analyzed according to the requirements. Then the next step is to start designing the architecture, main functions and database of the university campus charity auction website. The University Campus Charity Auction Website is based on the requirements analysis in the previous chapters, and its overall design module diagram is shown in Figure 3-2.
Figure 3-2 Functional module diagram of the university campus charity auction website
3.2.2 User module design
The background manager can add, delete, modify and check the users registered in the front desk. The structure diagram of the user module is as follows:
Figure 3-3 Structure Diagram of Member User Module
3.2.3 Comment management module design
The University Campus Charity Auction website is an open platform for communication. Member users can communicate on the platform to increase the interaction between users. But at the same time, in order to better regulate the content of the message and give the administrator the function of deleting inappropriate comments, it is necessary to design a message management module. The specific structure diagram is as follows:
Figure 3-4 Structure diagram of message module
3.2.4 Item management module design
The university campus charity auction website needs to store a lot of item auction information, and its module function structure, the specific structure diagram is as follows:
Figure 3-5 Structural Diagram of Item Auction Module
Database design generally includes three major processes: requirements analysis, conceptual model design, and database table establishment. Requirements analysis has been explained in the previous chapters, and conceptual model design has two parts: conceptual model and logical structure design.
3.3.1 Conceptual structure design of database
The following is the ER entity relationship diagram of the main database tables in the entire university campus charity auction website.
Figure 3-6 The overall ER relationship diagram of the university campus charity auction website
According to the database ER relationship diagram of the university campus charity auction website, it can be concluded that the university campus charity auction website needs many ER diagrams. Here are some main database ER model diagrams.

5系统测试
系统开发到了最后一个阶段那就是系统测试，系统测试对软件的开发其实是非常有必要的。因为没什么系统一经开发出来就可能会尽善尽美，再厉害的系统开发工程师也会在系统开发的时候出现纰漏，系统测试能够较好的改正一些bug，为后期系统的维护性提供很好的支持。通过系统测试，开发人员也可以建立自己对系统的信心，为后期的系统版本的跟新提供支持。
系统测试包括：用户登录功能测试、物品展示功能测试、物品添加、物品搜索、密码修改功能测试，如表5-1、5-2、5-3、5-4、5-5所示：

通过编写大学校园慈善拍卖网站的测试用例，已经检测完毕用户登录模块、物品查看模块、物品添加模块、物品搜索模块、密码修改功能测试，通过这5大模块为大学校园慈善拍卖网站的后期推广运营提供了强力的技术支撑。
至此，大学校园慈善拍卖网站已经结束，在开发前做了许多的准备，在本系统的设计和开发过程中阅览和学习了许多文献资料，从中我也收获了很多宝贵的方法和设计思路，对系统的开发也起到了很重要的作用，系统的开发技术选用的都是自己比较熟悉的，比如Web、Java技术、MYSQL，这些技术都是在以前的学习中学到了，其中许多的设计思路和方法都是在以前不断地学习中摸索出来的经验，其实对于我们来说工作量还是比较大的，但是正是由于之前的积累与准备，才能顺利的完成这个项目，由此看来，积累经验跟做好准备是十分重要的事情。
当然在该系统的设计与实现的过程中也离不开老师以及同学们的帮助，正是因为他们的指导与帮助，我才能够成功的在预期内完成了这个系统。同时在这个过程当中我也收获了很多东西，此系统也有需要改进的地方，但是由于专业知识的浅薄，并不能做到十分完美，希望以后有机会可以让其真正的投入到使用之中。

致 谢
逝者如斯夫，不舍昼夜。转眼间，大学生会员活便已经接近尾声，人面对着离别与结束，总是充满着不舍与茫然，我亦如此，仍记得那年秋天，我迫不及待的提前一天到了学校，面对学校巍峨的大门，我心里充满了期待：这里，就是我新生活的起点吗？那天，阳光明媚，学校的欢迎仪式很热烈，我面对着一个个对着我微笑的同学，仿佛一缕缕阳光透过胸口照进了我心里，同时，在那天我认识可爱的室友，我们携手共同度过了这难忘的两年。如今，我望着这篇论文的致谢，不禁又要问自己：现在，我们就要说再见了吗？
感慨莫名，不知所言。遥想当初刚来学校的时候，心里总是想着工科学校会过于板正，会缺乏一些柔情，当时心里甚至有一点点排斥，但是随着我对学校的慢慢认识与了解，我才认识到了她的美丽，她的柔情，并且慢慢的喜欢上了这个校园，但是时间太快了，快到我还没有好好体会她的美丽便要离开了，但是她带给我的回忆，永远不会离开我，也许真正离开那天我的眼里会满含泪水，我不是因为难过，我只是想将她的样子映在我的泪水里，刻在我的心里。最后，感谢我的老师们，是你们教授了我们知识与做人的道理；感谢我的室友们，是你们陪伴了我如此之久；感谢每位关心与支持我的人。
少年，追风赶月莫停留，平荒尽处是春山。
