- Use Memcached as session server to maintain session
- Three ways to maintain sessions: Sessionsticky session binding: By implementing a unified session in the configuration of the front-end scheduler and sending it to the same back-end server. Sessioncluster Session cluster: By configuring Tomcat to keep the information of all Tomcat sessions consistent. Sessionserver session service: Hand over all sessions to specialized session service management. Here we explain the third type, using Memcached as session server. 1. Architecture diagram.

- Online course selection management system based on SSM framework: a powerful tool to improve the efficiency of educational administration management in colleges and universities
- Other projects: Design and implementation of seismic data processing software based on Linux, click on the author's homepage Catalog 1 System Introduction With the development of the information age, design and implementation of seismic data processing software based on Linux, the Internet has made people's lives more and more convenient. In recent years, in the face of the new enrollment expansion policies of major colleges and universities, the number of middle school students in various colleges and universities has suddenly increased, and the corresponding school academic staff will also face a shortage. This has reduced the difficulty for academic staff in managing the course selection information of middle school students. , the traditional course selection in previous years was gradually eliminated because it was a waste of manpower and material resources. At this time, the emergence of the online course selection management system will promote the increasingly standardized course selection management behavior of middle schools, thereby greatly reducing the casualness of middle school course selection management in previous years and greatly improving the efficiency of course selection management.

- Nginx+Tomcat deployment operation of Angular+javaweb project
- Initially, I used ngbuild-prod-aot to compile and package. Note here that since it is now officially built-in, you only need to enter ngbuild–prod when packaging. Here you can compare it with the size of my project: ngbuild: 8,348,761 bytes ngbuild–aot: 9,232,405 bytes ngbuild–prod: 1,839,811 bytes ngbuild–prod–aot: 1,839,811 bytes Finally, it can be seen that ngbuild–prod can be completed. Minimum packaging for productization. I don’t understand something here. The pre-compiled build is larger than the regular build. I hope it will be bigger.
