Abstract: 【Purpose/significance】Relying on 5G communication technology, multi-dimensional technology and data warehouse tech⁃ nology, under the background of the development of smart society, design and analyze the framework of the microservice mode of smart university libraries to optimize the service mode of university teachers and students.【Method/process】Based on the research on the supporting technologies of a variety of microservice model frameworks, this paper adopts the agent microservice design model and com⁃ bines the past typical microservice application frameworks to design the smart library microservice model framework. Through system⁃ atic analysis of the four major modules of the framework's microservices: retrieval service module, recommendation service module, APP service module, WeChat public service platform module, etc., a comprehensive microservice model strategy for smart libraries is proposed.【Result/conclusion】By innovating smart library microservice content, expanding smart library microservice functions, culti⁃ vating smart library microservice staff, and continuously optimizing smart library microservice models, it can effectively guarantee the quality of smart library microservices to provide university teachers and students with personalized microservices.【Innovation/limita⁃ tion】Since this article does not verify the service model framework involved with actual cases, there are certain limitations, but this al⁃ so provides a new direction for subsequent related research.
