Compared with traditional monolithic architecture, microservice architecture has many advantages, such as flexible technology selection, independent scalability, high availability and so on, and is more suitable for the current needs of the Internet age. But microservice architecture also introduces new problems, such as cross-process communication, service registration, service discovery, and distributed session management. On the basis of analysis and comparison between the traditional framework and microservice framework, this paper shows one implementation method of microservice framework. First, we design a scheme of microservices architecture framework and the functional framework, and then give the solutions of some key issues that microservice architecture introduces. With this scheme, developers only need to focus on the development of business functions, service registration, discovery, monitoring and session management provided by the framework to simplify the development and improve development effectiveness.
