摘　　要： 国际互联网的出现缩短了地域之间的距离，减少了空间的限制，使地球变的更小。它是国与国之间，行业与行业之间，企业与企业之间建立联系的纽带。互联网为当代人类提供了无限的发展空间，为企业提供了宣传自我，提高形象、交流信息的快捷途径。随着电子商务时代的到来，国内外的市场竞争越来越激烈，机遇和挑战并存，传统的经营手段将难以适应今后的经济发展。所以建立功能强大的企业网站、加强企业网站的建设是大部分企业必然趋势。
　　 渤船重工于2002年开始由企业自己的研发部门开发并建立了自己的企业门户网站，建站初期，由于开发人员不足、水平不高等因素制约，使得企业门户网站的功能简单，开发技术也相对落后，最初的版本多是由简单的静态网页构成。随着企业的发展和开发人员技术水平的逐渐提高，不断对网站进行改版，网页构成也由单一的静态网页发展为动态网页与静态网页向结合，网站的功能也不断增强。
　　 信息技术的发展使企业内部网络与INTERNET的互连互通成为不可逆转的趋势，这在另一方面又给网络的信息安全带来威胁。特别是涉及国家秘密的军工企业重要网络，其信息安全将对国家政治、经济及国家安全产生影响，因此确保网络信息安全意义重大。同时这也对企业内部开发人员提出了更高的要求。如何构建一个更加规范、安全的网站，并且利用更加成熟的开发技术和拥有高水平的开发团队，在电子商务时代树立新的企业形象，是现阶段我们企业所面临的挑战。
　　 在这种前提和背景下，引出了本课题的研究，旨在建立更加安全、功能不断完善，开发技术不断成熟的渤船重工门户网站。
　　 本系统以J2EE为核心，采用MVC设计模式进行实现。并结合企业现状，对不同信任域网络的信息交换做了一定研究。本文着重对如下两个方面进行了探讨：
　　 ● STRUTS框架的WEB应用系统的工作原理和主要开发技术。
　　 ●在不同信任域网络中实现安全隔离下的WEB信息交换 The application of internet shortened the distances between different places, reduced restrictions of spaces, making earth a smaller world. The internet provided modern people an unlimited space in development, as well quick access in self-advertising, image promotion and information exchanging of the enterprises.As e-business time comes, cut throat competitions appeared in international and domestic markets, opportunities and challenges exists at the same time, so the traditional operating strategies are no longer suitable in the future economy development. Therefore, the establishment of a supper powerful enterprise website, as well the reinforcing of the website construction is the inexorable trend of those large enterprises. In 2002, the MVC of BSHIC was started in research and developing by its own department and then ended up a junior function website of static pages, due to lack and low level of technicians and lagging in technology. With continuously development of the enterprise and technology enhancing of the technicians, after website alternations from time to time, the structure of web pages was changed from single static one to the combination of dynamic and static pages, as well its functions were optimized. Connection between enterprise local net work and Internet is the irreversible trend lead by the development of information technology, but it also brings treats to network information security. Especially in the cases of State Secret concerned military enterprises, its information will cause influence in national politics, economies and public securities, therefore, it is deem important to ensure the security of network information. At meantime, this requires higher quality to the internal research staff of the enterprise. It is a challenge faced by the present enterprises in how to construct a more standard and secured website, moreover, at the time of e-business, to set up new image of the enterprise by adopting further matured developing technology and employing high level research staff. The research of this project is extracted under these above mentioned premises and backgrounds, for the establishment of a more secured, continuously optimized in function and development technology MVC of BSHIC. The core of this system is J2EE, and to achieve with MVC design mode. With integration of present status of the enterprise, and certain researches were done in different trust domain of network. ●Work principle and key development technology in web application system of Struts ●To achieve web information exchange by secured separation means in different trust domain of network.
