Research And Implement Of The Information System Of National Safeguard Of Public Secutity Based On Spring Framework

This topic originates from the Information System of National Safeguard of Public Security (ISNSPS), which is developed by the Municipal Public Security Bureau of Zhengzhou, Henan Province and the Electronic Commerce Engineering Research Center of Henan Province. The ISNSPS has currently been applied into practice by the Domestic Safeguard Branch of Zhengzhou Municipal Bureau of Public Security and has obtained good effect.The article has deeply discussed the Spring technology of lightweight development framework, analyzed the two core mechanisms named IoC and AOP and probed the Web MVC framework of Spring with emphasis, and other relative technologies such as Hibernate, Oracle, HTML, JSP, JTML are also explored in the article.According to the demand of the ISNSPS, the article analyzes the traditional client/server structure system as well as the design pattern of the three-layer-structure which is more advanced at present. On the basis of the three-layer-structure the improved Spring MVC and Hibernate frames are introduced, and so comes the formation of the developing and design pattern for ISNSPS called BISHD(Browser + Improved Sring MVC + Hibernate + Database). The concept structure and the logical organization of the database are thus designed, and then the view level, model level and control level are devised accordingly. Then the article describes the development environment of ISNSPS and construction of the data level and the service level in detail, and demonstrates the developing process of the functions of ISNSPS by taking the detailed information displayed in the analysis function as an example. In the end the dissemination and operation of the ISNSPS are illustrated.
