ABSTRACT
With the development of information technology, online examination system
supported by computer network technology has become a hot research topic in the field of
"Internet + education". However, the current online examination system is mainly based on
the traditional single architecture. With the increase of demand, such a system is prone to
serious functional coupling, difficult code overstaffed maintenance, long development
cycle, poor business scalability and other problems. Micro service is a new distributed
software architecture emerging in recent years. In order to solve the above problems, this
paper proposes an online examination system development model based on microservice.
This paper designs and implements an online examination system based on
microservice framework for university software engineering courses. This paper expounds
the whole process of system development from the aspects of system demand analysis,
system overall design, detailed design of functional modules, code implementation, system
test and so on. According to different business logic, the whole system is divided into four
independent business microservices, including student micro service, teacher micro
service, administrator micro service and general module micro service. In addition to the
business micro service, the paper also uses the components of Spring Cloud, such as
Eureka, Zuul and Feign, to realize the functions of service registration and discovery,
routing gateway forwarding and declarative interface invocation respectively.
This paper not only realizes the basic functions of the online examination system, but
also analyzes and improves the deficiencies of the existing examination system, adding
some characteristic functions, such as: online compilation, professional textual research,
anti-cheating, examination with the unit, automatic marking, data graph analysis,
post-examination communication and so on.
This paper is based on the teaching reform and practice of SPOC for small classes of
"Java Programming" for application-oriented undergraduate students, a research project of
education reform in universities of Hunan Province in 2018. The paper optimizes the
existing examination functions and integrates the characteristic module with the new form
of online examination and micro-service architecture. The application shows that the
system has the characteristics of security, availability and high performance. Meanwhile,
the system strengthens students' independent learning ability and interest, improves
students' practical programming level, and effectively improves teaching efficiency.
