System management will also carry out overall intelligent operation through the computer. There are a lot of management and data storage involved in the drug management system, such as administrators: home page, personal center, user management, employee management, drug category management, drug management Information management, drug storage management, drug delivery management, online consultation management, message board management, system management, order management, user: home page, personal center, online consultation management, my collection management, order management, staff: home page, Personal center, drug information management, drug storage management, drug delivery management, online consultation management, front home page: home page, drug information, medical guide, message feedback, personal center, background management, shopping cart, etc. The work brings huge challenges. In the face of a large amount of information, the traditional management system is to collect detailed information by taking notes. Later, computers appeared, and the paper-based information was counted on the computer through computer input software. This method is more traditional, and it is more troublesome to obtain statistical data information, and it is also affected by time and space, so a drug management system has been developed for this purpose.
environmental needs
1. Operating environment: preferably java jdk 1.8, which is currently the most stable JDK and the most used JDK version.
2.IDE environment: IDEA, Eclipse can be. IDEA is recommended;
3.tomcat environment: Tomcat7/Tomcat8/Tomcat9 versions are available
4. Hardware environment: Windows 7/8/10 with more than 1G memory; or Mac OS;
5. Database: MySql version 5.7;
6. Whether Maven project: yes;
technology stack
Backend: Spring+SpringMVC+Mybatis+Springboot
Front-end: vue+CSS+JavaScript+jQuery+elementui

SpringBoot is the most popular framework at present. Its configuration is simpler, making development easier and faster.
The infrastructure of Spring Boot consists of three files, as follows:
src/main/java: program development and main program entry;
src/main/resources: configuration file;
src/test/java: Test program.
The SpringBoot project supports two formats of configuration files by default
1,application.properties
2,application.yaml
Front-end technology: nodejs+vue+elementui.
