| Informatization development in towns is one of the most basic and weakest steps in the process of the rapid development of the informatization construction of our country. So, it is an urgent task to speed up the informatization development in towns so as to promote the informatization construction of our country. The government plays an important role in realizing informatization development in towns. Therefore, carrying out e-government in towns will promote the informatization development in towns enormously.The towns' economic condition is quite weak in general. So, the most important question we should take into consideration is to control the development cost. Another question is to ensure the possibility of the system to be extended and used in other fields so as to make it convenient to be applied widely. The middleware technology has a good performance not only in enhancing the reusable and extensible possibility of the software but also in reducing development cost. Therefore, this article researches and realizes e-government system of towns based on middleware technology.After doing enough research on the mainstream middleware standard and the current popular web development frame, I propose a middleware model based on SSH frame (struts frame, spring frame and hibernate frame for short) and analyze the structure, flow and merit of this model. And then this article discusses the application of middleware model in towns' e-government and presents the realization code of actual module.The e-government system of towns which is developed on the basis of SSH frame middleware model provides a kind of plug-and-play and mutually operational software which is in the application layer. According to the different situations of different towns, the system can be reassembled to suit local condition so as to meet the actual demand. Therefore, it reduces the development cost efficiently and does well to the popularization and application of the e-government in towns. |
