1. research significance
The 19th National Congress of the Communist Party of China (NPC) recently held its symposium in-depth and the 19th-CPC National Congress emphasized that accelerating the building of a powerful nation requires fostering a new growth point in areas such as green and low carbon. With the improvement of college students' living conditions, the speed of updating of items becomes faster and faster, more items become idle, and these idle items are often the necessities of other people or can be reused to save resources.
2 the basic content of the subject and requirements
2.1 basic content
There are several modules of user management, information management and message management to be developed on the campus idle goods trading platform. User management is divided into user registration, user login and user information management. Information management is divided into information release, information retrieval and information management, and information Management includes transaction information management and chat information management. Campus idle goods trading platform
(1) user management template
User registration under a student ID password a new user. Registration of the school whether the school number exists for inspection, and the student's own real-name system, and check whether the password is consistent with the rules. Verify the student ID and password entered by the user, pop-up prompt message when the error occurs, and the user can log in normally when the user is correct. Manage user information, modify user passwords, delete users, and retrieve users.
(2) Information Management
The administrator user posts the information to the information platform for others to query and browse. Users according to their own needs, used keywords to retrieve the information they need, but also through the classification to find information. The classification of information: First, the classification of items to be classified, for example: books, appliances, clothing, electronic products, etc .; two is in accordance with the latest release of time goods classified display. Sold items will be marked sold out.
(3) message management
First, transaction information between users and administrators to facilitate the statistics and summary of information, the second is the user and the administrator to maintain their chat records between the communication, in the event of a dispute, you can coordinate the chat information based on both issues.
The project to the waterfall model development, development tools used development environment is Apache Tomcat 7.0 / MyEclipse 9.0 and some related software, the development language is JSP, using a database server for MySQL.
In the process of design, we will make reference to some of the similar websites at home and abroad, learn from some of their layout frameworks, and organize the basic functions of the subject requirements rationally to form a friendly, efficient and interactive process. So that users use more simple and convenient.
3.1 research steps
Mainly divided into six steps, including theoretical preparation, requirements analysis, the overall design, detailed design, coding, system testing. The general steps for each step are as follows:
(1) Theoretical preparation
This step is the basis of the entire research process, mainly through reading the relevant information, query the status quo of students recycling, access to technical materials, the project has a holistic understanding of the learning and development of the necessary technologies, on the basis of theory Prepare for the next steps.
(2) needs analysis
Understand the needs of the campus, the development needs of web pages and the analysis of the needs of students' unwanted goods transaction websites after the development of web pages. Analyze requirements and describe requirements for resource reuse.
(3) the overall design
According to the overall goal of the design of modules, and for each module come up with feasible solutions.
(4) Detailed design
Detailed system design phase, including the design of the database, the establishment of the table, such as product lists, student information form. Establish the overall structure of the target system and the relationship between modules, define the interface of personnel management, management and other functional modules, control interface. The overall design of the module, the provisions of the design constraints, the development of assembly test plan.
(5) coding
The detailed design instructions into the required programming language or source code. And the preparation of good source program unit test, verify the program module interface and detailed design specification consistency.
(6) system testing
The entire system functions to test, write test documentation. The test method mainly uses black box test.
