Modern distance education system design based on struts2

For lack of a whole system structure design in the design of distance education system under current situation, this paper proposes the system structure, basic system framework design and basic system framework realization of a three-layer distance education platform based on struts2. The framework design not only takes full account of the requirement of system functionality, but also satisfy non-functional requirements including expandability, transportability and robustness, so it has provided a solution for the difficult maintenance of large-scale software.
