Summary
This article is a general summary of the university dormitory management system. It mainly elaborates on the university dormitory management system from the perspectives of topic background, topic significance, research content, development environment and technology, system analysis, system design, and system implementation.
The university dormitory management system is developed using idea tools and coded using Java language. The backend framework uses the SSM framework (Spring framework, SpringMVC framework, MyBaites framework) for design separation. The database uses the Mysql database to save the generated data generated by this system. The data. The system can provide information display and corresponding services. The system administrator manages dormitory visitors and dormitory information, manages dormitory water and electricity meters and corresponding payment information, and manages repair applications and student information. Dormitory administrators manage dormitory health inspection information and student absence information. Students can check the balance of electricity and water meters and their corresponding payment information, register items for repair, and check dormitory health inspection and absence information.

Abstract
This article is a general summary of the college dormitory management system, mainly from the background of the topic, the meaning of the topic, the research content, the development environment and technology, system analysis, system design, and system implementation to explain the college dormitory management system.
The university dormitory management system is developed using Eclipse tools and coding in Java. The back-end framework adopts SSM framework (Spring framework, SpringMVC framework, MyBaites framework) for design separation, and the database adopts Mysql database to save the generation of this system. The data. The system can provide information display and corresponding services. The system administrator manages dormitory visitors and dormitory information, manages dormitory water and electricity meters and corresponding payment information, and manages repairs and student information. The dormitory administrator manages the dormitory sanitation inspection information and student absence information. Students inquire about the balance of electricity and water meters and their corresponding payment information, apply for repairs of registered items, and inquire about dormitory sanitation inspection and absenteeism information.
Key Words：College dormitory management system; Java language; Mysql
