2 System development environment
2. 1 Introduction to JSP technology
JSP technology is released by sun company , which uses jsp technology to develop dynamic web applications. It is characterized by being easy to learn and cross-platform operation. It is the most suitable among many dynamic Web application design languages. In just a few years, it has formed a complete set of specifications and is widely used in e-commerce and other fields. in the field. In China, JSP has attracted everyone's attention and has developed very well. More and more dynamic websites have begun to adopt JSP technology. The following is a brief introduction to JSP and its related technologies. JSP technology can generate Web pages in a simple, convenient and fast way. Web pages using JSP technology can easily display dynamic content. JSP technology is designed to make it easier and faster to construct Web-based applications that can work with a variety of Web servers, application servers, browsers, and development tools.
2.2 B/S mode
The B/S structure is currently the most commonly used structural model. It can make system development simpler, easier to operate, and can also be maintained. When using this structure, you only need to install a database in your computer and some commonly used browsers. The browser will connect the information with the database, which can realize many functions. The B/S structure can be used directly, and the B/S structure greatly reduces the maintenance work during use. Based on B/S software, all databases are independent of each other, so they are very safe. Because based on the B/S structure, you can clearly see the business being processed by the system, and allow managers to make decisions in a timely manner , thus avoiding developers ' losses. The basic feature of the B/S structure is the centralized management model. After users use the system to generate data, the data can be stored in the system's database for future use, thus meeting all people's needs.
Figure 2-1 Three-layer structure diagram of B/S mode
2. 3 MySQL environment configuration
(1) The data of this system uses MySQL, so MySQL must be installed in the specified directory. If you download a non-installed MySQL compressed package, just decompress it directly to the specified directory. Then click on the file C:\Program Files\MySQL\bin\winMySQLadmin.exe where C:\Program Files\MySQL is the MySQL installation directory. Enter the initial user and password of winMySQLadmin (note: this is not the user and password in MySQL). Don’t worry. After confirmation, a traffic light icon will appear in the task launch bar in the lower right corner. The red light means that the service is stopped, and the green light means that the service is stopped. Normally, left-click this icon->winnt->install the service to install the service, then left-click this icon->winnt->start the service to start the MySQL service.
(2) Modify the root password of the MySQL database. Use cmd to enter the command line mode and enter the following command:
cd C:\Program Files\MySQL\bin
MySQLadmin -u root -p password 123
Enter password: appears when you press Enter. This is to enter the original password. The password was empty when it was first installed, so just press Enter. At this time, the password of the account root in MySQL is changed to 123 and the installation is completed.
2.4 SSM framework
The mainstream framework for developing information management systems is SSM (Spring + Spring MVC + MyBatis) . The SSM framework web layer uses the Spring MVC framework to make it simple to transmit front-end and back-end data; for the business layer, the Spring framework is used as a lightweight control inversion ( IoC) and aspect-oriented (AOP) container framework; for related SQL operations, Mybatis is used as the persistence layer framework to encapsulate JDBC, making the underlying operations of the database transparent to developers .
3 System analysis
3.1 System feasibility analysis
3.1.1 Economic feasibility
Since this system is a graduation project system , and the system itself has some technical flaws, it cannot be directly used for commercial purposes. I just want to improve my academic level through the development of this system, without the need for additional expenses such as special servers. All creation and work processes can be realized only on a personal computer. Most of the software used is open source software, so the economic cost is not high and it can be easily implemented.
3.1.2 Technical feasibility
The development of this system uses JSP as the development technology for system development . Eclipse is selected as the development tool . The B /S structure determines the compatibility and multi-user operability of this system. In addition, choosing MySql as the database not only improves data security but also ensures improve the operability of data.
3.1.3 Operational feasibility
This system uses JSP as the development technology , and the choice of B /S structure determines that operating this system only requires very small resources and does not require too many hardware configurations. Currently, as long as the browser can run normally on the market All personal computers can run normally using this system.
In summary, the economic, technical, and operational conditions for the design and development of this system are all met. Therefore, system development has feasibility conditions.
3. 2 Analysis of website status
The number of users using the system directly determines the workload of user information managers. There is no doubt that the workload of website managers is larger and more cumbersome . Through preliminary research, the current user management status of the website is summarized as follows:
Lack of overall planning . If a website lacks comprehensiveness, systematicness, and integrity in information management, it will inevitably require a lot of manpower and material resources to plan and organize information. The introduction of information management methods can undoubtedly achieve the purpose of saving information management costs. It can not only reduce the waste of resources, but also make skin care product recommendation information more organized, which has become a major advantage in market competition.
You must proceed step by step. You cannot eat hot tofu in a hurry. Nothing can be accomplished overnight. Even the information management system is the same. To maximize the efficiency of the system, you should do more research, listen to the opinions of instructors and classmates , and carry out necessary overall planning. The organization designs system functions purposefully and unites various departments to exert their subjective initiative.
( 1 ) Information security measures are not in place
The right to privacy is sacred and inviolable. This is the right granted to us by the Constitution of the People's Republic of China. No one can infringe upon our legitimate rights and interests. However, there are great security risks in the management of network user information, and there are many cases of information leakage. Strengthening information security Measures are an inevitable part of the process of improving network information management.
( 2 ) Resources cannot be fully shared
Resource sharing is a major feature of the Internet. Without sharing, there would be no social interaction, and the Internet would lose its charm. If skin care product recommendation information can be shared, it will undoubtedly be indispensable for the development of shopping malls .
( 3 ) The existing system has low scalability.
Nowadays, science and technology are developing rapidly, and what follows is technological updates, which will inevitably bring challenges to software updates. Therefore, the system must have good openness and scalability. In order not to lag behind the times, this is a must-have feature one .
Based on the above analysis, the skin care product recommendation system should be realistic and effective. The collective performance is as follows: first, the system can organize and aggregate user information to prevent user information from being chaotic and difficult to sort; second, the system must be safe and stable and cannot be leaked. User information will cause privacy leakage, which will not only harm the interests of the mall but also damage the reputation of developers ; thirdly, the system must have good openness, not only to facilitate regular maintenance and repair, but also to facilitate the timely addition of new functions to ensure the advanced era Fit. After detailed discussion and demonstration, the overall requirements of the system are determined .
3.3 Functional requirements analysis
System functional requirements analysis is based on detailed and careful thinking by software developers after participating in market research, communicating with tutors and classmates , and then discussing and researching the functions required for preliminary system development . This is the first and crucial step in development. If you do not formulate the required modules for the system at this stage, it will cause unnecessary trouble in the future. Therefore, you must be serious and devote yourself to this step.
This system is developed using a top-down approach and basically positions the following functions:
This topic requires the implementation of a skin care product recommendation system . The system mainly includes the administrator module and the user module function module.
