1. Introduction to the environment
Locale: Java: jdk1.8
Database: Mysql: mysql5.7
Application server: Tomcat: tomcat8.5.31
Development tools: IDEA or eclipse
Development technology: Springboot+Vue+HTML
2. Project Introduction
The rapid update and development of science and technology have effectively promoted the progress of computer technology, thus laying a solid foundation for the promotion and application of computer technology in society. The emergence of computers has greatly promoted the progress and development of all walks of life in society, provided an effective path for the spread of human historical civilization and culture, and helped human development create a large amount of wealth. Since science and technology are the primary productive forces in social development, the development of science and technology consists of the application and promotion of computer technology. In recent years, due to the development of computer technology, its application fields have gradually spread from the initial military and scientific research fields to all aspects of people's production and life. Today, human society has developed from industrialization to high informatization, and the impact of computer technology on people is also increasing day by day.
With the advent of the information age, management systems tend to be intelligent and systematic, and the epidemic prevention material management system is no exception. However, manual management is still used in China. The market size is getting larger and larger, and the amount of information is also increasing. It is huge and manual management is obviously unable to cope with the changes of the times. Computers have the most common storage functions, computing and control functions, and input and output functions. These functions can quickly improve efficiency, save time, and continuously reduce computing costs and labor costs. At the same time, they are more scientific, standardized, and accurate than manual operations. Therefore, the epidemic prevention material management system can solve this problem well and easily handle the daily work of epidemic prevention material management. It can not only improve human, material and financial resources, but also speed up the work efficiency. It is an inevitable trend to replace manual management.
The epidemic prevention material management system uses SpringBoot as the framework, B/S mode and MySql as the database running in the background, and uses Tomcat as the system server. This system mainly includes functions such as home page, personal center, user management, material management, material type management, material leasing, online communication management, community announcement management, news information management, rental list management, outsider reporting, etc. The realization of these functions is basically Able to meet the daily operations of epidemic prevention material management.
This article focuses on the analysis, design and implementation of the epidemic prevention material management system. It first introduces the development system and environment configuration, and the design of the database, then explains the detailed implementation of the functional modules, and finally makes a summary.
