Abstract: As an important component of the university’s information infrastructure platform, the information portal has been continuously evolving. As an aggregation portal for information applications, the information portal provides one-stop system services such as information push between intranet and extranet and system integrated function. Traditionally, the enterprise service bus (ESB) is adopted for the service integration of multiple applications, and has the disadvantages of complex integration and difficulty in iterative change. Microservice architecture, a new type of distributed architecture, is widely used in the Internet industry. Through the research on microservice architecture and information portal, an application model of distributed portal service integration by harnessing Spring Cloud is proposed, which is put into practice in the concrete one-stop portal construction.
