HeTong: A Voice Answering Enabled Multi-language Questionnaire System Based on Spring Cloud

In view of the fact that current web questionnaire systems are not suitable for use by specific groups such as those at multi-ethnic inhabited multilingual area, and the status quo that the questionnaire systems based on monolith architecture are difficult to expand and maintain, we designed and implemented HeTong based on Spring Cloud, a frame of microservice architecture that is easy to extend and upgrade. HeTong is a multi-language questionnaire system that enables voice input for subjective investigation questions apart from general functions of conventional questionnaire systems. In this paper, the microservice system design for HeTong is introduced. Firstly, the overall framework of HeTong is described. Secondly, the business logic module is designed in detail where different types of microservices are divided according to different functions. Then, the business logic module is implemented based on Spring Cloud. Finally, the interactive interface between the user and the system is designed. The software tests show that the system can well realize the functions of language switching, user management, questionnaire management, data statistics and voice answering.
