Research on Network Teaching System Based on Open Source Framework

In this paper, the generics DAO schema is introduced into the lightweight J2EE application architecture based on open source framework of Spring, Hibernate and Struts. The data access code is enabled to offer the type-safe interface, which can avoid compulsory type conversion that belongs to the fallible repetitive development. The architecture scheme is applied to the development of the network teaching system, and the design and implementation procedure is given by example. Finally, the practice shows that the method presented by this paper enables the architecture to provide high reusability, expansibility and maintainability, and makes the system development more simple and efficient.
