Design and implementation of online judgment system based on microservice architecture and Docker

The online judgment system tests whether the source code can pass the problem’s test cases in the programming contests. Users only need to click the submit button on the front-end page, and the system will return the judge results after a certain period. Although there are many online judgment systems for programming contests, there are few online judgment systems for programming teaching and adopting a microservice architecture. This paper aims to design and implement an online judgment system for programming teaching. The system’s front-end adopts Vue and Element-Ui framework, and the back-end adopts microservice architecture for development. On the one hand, using the system can improve students' programming ability and teachers' efficiency and accuracy in marking programming assignments. On the other hand, the system has an online contest function, which can hold contests or be used as an examination platform to assess students' actual levels.
