Chapter 2 Development Technology and Environment Configuration
A traffic management information system was developed using JSP as the development technology , the current advanced SSM framework, Eclipse as the system development tool, and MySQL as the backend database .
2.1 Introduction to JSP technology
This traffic management information system mainly uses JSP technology in the background management of web page effects. Now more and more software traffic management uses JSP technology to develop web-side applications. Because as far as the web page production modules currently on the market are concerned, the content contained in JSP technology is relatively rich and comprehensive, and JSP technology has become the most common web page development technology on the market today. The full name of JSP in Chinese is JSP server-side language. We all know that JSP is a dynamic web development technology, and its development is cross-platform. JSP can run on the Windows operating system or Linux system. JSP is a relatively simplified web page technology. It is a dynamic web page technology standard jointly initiated by many traffic managers . In JSP, you can insert html web pages, CSS, JSP script, etc. to create dynamic web pages, and the styles are more diverse.
2.2 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 .
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 Introduction to mysql database
Utilizing MYSQL's data independence, security and other features to operate data in software projects can ensure data accuracy and reduce programmers' application development time.
The characteristic of MYSQL is that it supports multi-threading, can make full use of system resources conveniently, effectively improves speed, and also provides multiple ways to connect to the database; MYSQL's functions are relatively weak and small in scale, but the system requirements are not high. MYSQL can fully meet the needs of this website.
Using MYSQL to establish a system database is not only conducive to the early integration of data processing business, but also conducive to the development of the latter two data expansion operations.
2. 5 B/S architecture
Applying the B/S mode when sending requests to other users has a unique advantage: when users send requests to other Web servers through the network, they only need to use the browser to implement this function. One of the benefits of this function is that it effectively simplifies the client. Most of the developed software only requires the use of a browser. The normal operation of the client is achieved through these browsers, while the server is responsible for storing and reading data. Other multifunctional jobs.
B/S architecture mainly consists of three layers: presentation logic layer, control logic layer, and data layer. Representation of the logic layer: The function of service request is mainly of the logic layer. After the Web server is ready, the service request is sent first. After the first request is received by the server, the received request information will be identified on the web server. The identification operation is performed by the server. As long as the server identifies the request operation, the received request information will be identified. The information is returned to the client, and the browser receives the requested information. Control logic layer: The user's request is received by the control logic layer. The corresponding program and database connection are the first conditions for receiving the user data request. Then the request information data is processed. The request data is processed and returned to the Web server. The final processing is completed . The results are finally returned to the client through the web server again. Data layer: The main task of the data layer is for the server to receive requests from the Web server, but it also includes performing database query, modification, and deletion operations. Finally, the database operation results will be returned to the Web server. The relationship between the three layers of representation logic layer, control logic layer and data layer is independent, but the three layers are interconnected with each other.

2.6 Tomcat server
Tomcat is a small and lightweight application server. It is commonly used in small and medium-sized systems and situations where there are not many concurrent access users. It is the first choice for developing and debugging JSP programs. You can think of it this way,
When the Apahce server is configured on a machine, it can be used to respond to access requests for HTML pages. In fact, the Tomcat part is an extension of the Apache server, but it runs independently, so when running tomcat, it actually runs as a separate process from Apache. OracleOracle database system is a set of software products with distributed database as the core provided by Oracle Corporation of the United States (Oracle). It is currently one of the most popular client/server (CLIENT/SERVER) or B/S architecture databases. Oracle database is currently the most widely used database management system in the world. As a general database system, it has complete data management functions; as a relational database, it is a complete relational product: as a distributed database, it implements Distributed processing capabilities. But for all its knowledge, as long as you learn Oracle knowledge on one model, you can use it on various types of machines. Can run on all major platforms (including windows). Fully supports all industry standards. Adopt a completely open strategy. This enables customers to choose the most suitable solution. Full support to developers.
Chapter 3 System Analysis and Design
3.1 Feasibility analysis
