The Research And Application Based On OSGI Technology

With the development of modern transportation technology,the development of China’s civil aviation industry develops very fast, the flight continued to grow rapidly,this puts forward higher requirements for the operation of the domestic airlines.The involvement of information must consider as the measure to solve these problems.How to guarantee the operational capacity of the airport and flexible responseon the market is the startingpoint for this research.From the problems faced by the civil aviation industry and the business functional requirements,the author found that the OSGi technology can be a good solution to these problems.This project is based on the research and application of OSGitechnology,by researching the principles and applications of OSGi technology we finally complete the development of airport information integrated system. The main work of the project is developingthe airport information integrated systembased on the OSGi technology, and completingthe privilege system of the airport information integrated system. The system alsoachieves CAS for different subsystems of airport information integrated system based on OSGi technology.We introduce the OSGi conceptual issues in this paper firstly, mainly includes the principles and characteristics of the OSGi. Secondly, we introducehow OSGi technology for plug-in development,and introduce some techniques used in the airport information integrated system, including MVC design pattern and ExtJs framework.Thirdly,we analysis and design the various modules of the airport information integrated system, mainly consistingthe privilege system of the airport information integrated system, and introduce how to realize CAS based on OSGi technology.Finally, we introduce the system’s functional testing.
