Research And Development Of Dynamic Service Management For Tourism Electronic Mall System Based On Distributed OSGi

In today's network environment,changing business requ:irement undoubtedly makes the function of tourism e-mall system more complex,larger scale and the changes in demand are more frequently.Traditional software development methods can no longer meet the rapid changes in business service requirements.How to shorten the development cycle,reduce the development cost and ensure the effective decomposition of software development projects is the common problem faced by the entire software industry.In order to solve these problems,this paper studies the dynamic loading of modules and the principle and application of OSGi framework.Based on distributed OSGi,a system that can dynamically manage services is implemented to achieve "plug and play" and "delete and non-existent" services.The main tasks are as follows:(1)Research on the system architecture for dynamic management of distributed OSGi services.According to the research background,this paper deeply studies the OSGi specification and also analyzes its framework implementation and distributed implementation.Using Equinox+Spring-DM+CXF-DOSGi to realize the development of application system,and to ensure that the dynamic management characteristics of system modules and remote calls of services can be realized according to users' needs.(2)Module division and implementation of tourism e-mall system.According to the increasing functional requirements of the tourism e-mall system in the information construction process,this paper implements a system based on distributed OSGi dynamic service management.The key to achieving high-quality design is to effectively decompose the system to ensure high cohesion and low coupling of the module.Therefore,according to the system requirements,this paper describes in depth the division,design and implementation of Bundle in the system.In addition,this paper also elaborates how the system implements distributed deployment in detail to achieve service remote call.(3)The test and analysis of dynamic service system based on distributed OSGi.In order to verify the dynamic management characteristics of the e-mall system implemented in this paper,the system is tested for running to verify the system's dynamic characteristics by installing,uninstalling,starting,and stopping the management system's Bundle.Finally,this paper analyses and summarizes the research and application based on distributed OSGi,and obtains its advantages in the application process.
