| Currently, J2EE is the best platform for enterprise software development. E-fax system is a typical WEB application system that based on J2EE, the thesis research the subsystem which is composed of some functional components in the system. The subsystem provides import functions including sending e-fax,the management of the inbox, outbox, contactor book module etc.Based on analyzing the demand of subsystem, the thesis build the backend architecture of the system with lightweight framework Spring combined with iBATIS on the principle of reducing the coupling, increasing flexibility. Then by analyzing the structure of the system with the use case diagram and data flow diagram, the thesis design and implement the send module, the received module, the contactor module and deleted module in the system. In the process of implementation, in order to improve the efficiency of development, the thesis on the one hand made some improvement for the way of dependency injection in Spring framework, on the other hand made some improvement for the mapping way between page request and controller. Finally, in order to improve the efficiency of writing test methods, the open source testing framework JTester was integrated to the system to prepare test data and complete the test of the system. Through the running and testing it shows that the subsystem is a highly efficient and reliable system. |
