1 Introduction
1.1 Research Significance
Through the analysis of the current research status of the network renting system at home and abroad, the deficiencies in it are found; a new model of the network renting system is proposed. The system is composed of three parts: user information query module, housing information management module and rental management module; and a corresponding application system is developed on this platform, which realizes the online rental function and provides users with convenient and fast online rental services, thereby Improve people's awareness and utilization rate of online renting. This paper also briefly introduces the key technology of the system——Web programming language; finally, it gives the test results of the whole system. This system has good practicability and expansibility, can meet the needs of most people, and can be extended to other fields. The actual operation shows that the system is practical and reliable, and has achieved the expected goal. At the same time, some deficiencies and improvements are pointed out, and the next research direction is proposed. Hope to lay a good foundation for further in-depth research in the future.
1.2 Research status and development trend
With the rapid development of the Internet, more and more people use the Internet for various exchanges and communication, but they also face many security problems. In this case, how to ensure the information security in the network environment is a very important and urgent problem to be solved. At present, domestic and foreign scholars' research on network security technology mainly focuses on intrusion detection, firewall and so on. However, there are relatively few researches on user authentication technology. Since most of the current online housing rental systems require users to enter their real names and ID numbers to enter the room, the accuracy of user identities directly affects the stability and reliability of the entire system. In addition, with the advent of the e-commerce era, people pay more and more attention to the safety of online shopping, which requires us to improve the safety factor of online transactions. Therefore, it is imperative to study an efficient and reliable network rental authentication mechanism. Based on the in-depth study of the current mainstream authentication technology, combined with the current network topology, this paper designs a new network rental platform. It uses third-party software to manage and maintain various functional modules of the network rental system. The platform can effectively ensure that private data such as user identity information and house status are not leaked or tampered with. At the same time, it can also realize the identity verification of the tenant, so as to ensure the security of the tenant's property. Since the traditional means of identification can no longer meet the growing needs of people in modern society, how to build a more secure, reliable, efficient and easier-to-operate authentication mechanism is particularly important. The authentication technology based on public key cryptography shows unique advantages in solving this problem. It can not only resist various attacks, but also has high security, high efficiency and low cost. Therefore, it has received extensive attention and research.
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.

Chapter Five: System Testing. Chapter 5 mainly tests some interfaces of the system and tests the main functions
2 Analysis of online house rental system
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 network rental system, 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 network rental system, I divided it into two parts: the registered user management module and the administrator management module.
User management module:
(1) User registration and login: the user registers as a member and logs into the online rental system; the user adds, deletes, modifies and checks personal information, such as personal information and password modification.
(3) Bulletin board: On the navigation bar of the homepage, we will see the menu of " Bulletin News ". After we click to enter, we will see the bulletin information released by all administrators in the background;
(4) Housing information: On the navigation bar of the home page, we will see the menu of " Housing Information". After we click to enter, we will see all the housing information released by the administrator in the background. Like the listing information, if you want to find this information faster next time, you can also bookmark and comment;
(5) Housing information : On the navigation bar of the homepage, we will see the menu of " Housing Information ". After we click to enter, we will see all the housing information released by the administrator in the background . We choose to know For the reservation information of the listing , you can like + bookmark + book + 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) Site management: When you click on the "Site Management" menu, two sub-menus will appear, carousel map + bulletin board, and you can add, delete, modify and check these two modules;
(3) User management: When you click on the "User Management" menu, two sub-menus for administrators and registered users will appear, and you can add, delete, modify and query these two
(4) Content management: When you click on the "Content Management" menu, there will be two sub-menus of housing information + information classification , which can manage the housing information submitted by the user at the front desk , and at the same time manage the housing information displayed at the front desk. Add, delete, modify and check the source information ;
(5) More management: When you click on the "More" menu, four sub-menus will appear: housing information + area management + room type management + housing reservation , and you can add, delete, modify and check these four modules ;
2.3.2 Non-functional analysis
The non-functional requirements of the online rental system, such as the security, reliability, performance, and scalability of the online rental system, etc. Specifically, it can be expressed in the following table 3-1:
Table 3- 1 Table of non-functional requirements of the network rental system
| safety |
Mainly refers to the installation of the network rental system database, the use of the database and the setting of the password must comply with the norms. |
| reliability |
Reliability means that the network rental system can be installed and operated according to the user's instructions. After testing, the reliability is more than 90%. |
| performance |
Performance is a necessary condition for the network rental system to occupy the market, so the best performance is good. |
| scalability |
For example, the database reserves multiple attributes, such as the use of interfaces, to ensure the non-functional requirements of the system. |
| ease of use |
Users only need to follow the page display content of the network renting system to operate. |
| maintainability |
The maintainability of the development of the network rental system is very important. After testing, there is no problem with the maintainability |
2.4 System use case analysis
Through the analysis of 2.3 functions, the use case diagram of this network rental system is obtained:
Figure 2-3 shows an example of a user role.
Figure 2-3 User role use case diagram of the network rental system
The administrator on the web background management maintains all data information in the entire network rental system. Figure 2-4 shows an example of an administrator role.
figure 2-4 Network rental system administrator role use case diagram
This chapter mainly determines the functions to be realized by the entire network rental system through the feasibility analysis, process analysis, functional requirement analysis, and system use case analysis of the network rental system. At the same time, it also provides a standard for the code implementation and testing of the network rental system.
3 Overall Design of the Network Rental System
This chapter mainly discusses the functional module design and database system design of the network rental system.
3.1 System architecture design
The network renting system 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 diagram of the network rental system
Presentation layer (UI): Also known as UI layer, it mainly completes the UI interaction function of the online housing rental system. A good UI can improve the user experience of users and enhance the comfort of users when using the online housing rental system. The UI interface design should also adapt to different versions of the network rental system and different size 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 network rental system. 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 this network rental system 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 network The data storage and management function of the rental system.
3.2 System function module design
3.2.1 Overall functional module design
In the last chapter, the functional requirements and non-functional requirements of the system are mainly analyzed, and the use cases in this network rental system are analyzed according to the requirements. Then the next step is to start designing the architecture, main functions and database of this network rental system. The network rental system is obtained 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 block diagram of the network rental system
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 online house rental system is an open platform of communication nature. 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 Housing information management module design
The network rental system needs to store a lot of housing information, and its module function structure, the specific structure diagram is as follows:
Figure 3-5 Housing module structure diagram
3.2.5 Housing reservation management module design
One of the most important functions of the network rental system is reservation . Its module function structure, the specific structure diagram is as follows:
Figure 3-5 Structure Diagram of Housing Reservation 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 network rental system.
Figure 3-6 Overall ER relationship diagram of the online housing rental system
According to the total ER relationship diagram of the database of the network rental system, it can be concluded that the network rental system needs many ER diagrams, and some main database ER model diagrams are listed here.
Figure 3-7 Registered user ER relationship diagram
Figure 3-8 ER relationship diagram for housing reservation
Figure 3-9 ER relationship diagram of housing information
Figure 3-10 Comment ER relationship diagram
3.3.2 Database logical structure design
From the total ER relationship diagram in the network rental system in the previous section, it can be concluded that a lot of data tables need to be created. Here I mainly list several major database table structure designs.

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、房源展示功能测试、房源添加、房源搜索、密码修改功能测试，如表5-1、5-2、5-3、5-4、5-5所示：

通过编写网络租房系统的测试用例，已经检测完毕用户登录模块、房源查看模块、房源添加模块、房源搜索模块、密码修改功能测试，通过这5大模块为网络租房系统的后期推广运营提供了强力的技术支撑。
至此，网络租房系统已经结束，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。
