基于Struts+Hibernate+Spring的轻量级J2EE框架 总被引:3,自引:1,他引:2
由于传统的J2EE框架开发、维护成本过高以及学习曲线陡峭,其在市场上的应用并不广泛。轻量级J2EE框架可以减少传统的J2EE开发、维护成本。通过Struts+Hibernate+Spring技术,开发轻量级J2EE框架,并通过一个企业MIS系统展示轻量级J2EE架构流程的优势。使用Struts+Spring+Hibernate技术整合的框架能够极大地规避开发维护困难的风险。基于Struts+Hibernate+Spring的轻量级J2EE框架值得研究和开发,值得推广。轻量级J2EE框架整合了Spring与Struts、Hibernate,开源的框架,不仅降低了系统开发的费用,并且开源还能够保证框架功能的完善。 相似文献

The author observes that the social fabric of engineering, the support infrastructure of the profession, and the political and economic systems of the world are undergoing shifts that affect what engineering is, how it is accomplished, and what it should do. He asks what these changes mean in terms of the educational system and explores a few of these issues that lie between academia and the industrial environment beyond. He discusses the engineering curriculum as seen from industry, the role of continuing education, research in academia 相似文献

目前所谓的全光网络一般指基于DWDM传送技术的光传送网络(OTN)。由于OTN的节点采用OADM和OXC技术,为解决目前点到点的DWDM技术在应用中不能实现灵活组网和当网络失效时不能有效进行保护的问题提供了一种解决方法,使得OTN具有传输容量大、组网灵活、网络具有可扩展性和可重构性、易于升级等特点,可透明传输具有代码格式的不同速率等级的用户数字信号,能够同时适应用户信号种类用服务种类不断增长的需求。 相似文献

The deposition of silicon carbide thin films and the associated technologies of impurity incorporation, etching, surface chemistry, and electrical contacts for fabrication of solid-state devices capable of operation at temperatures to 925 K are addressed. The results of several research programs in the United States, Japan and the Soviet Union, and the remaining challenges related to the development of silicon carbide for microelectronics are presented and discussed. It is concluded that the combination of α-SiC on α-SiC appears especially viable for device fabrication. In addition, considerable progress in the understanding of the surface science, ohmic and Schottky contacts, and dry etching have recently been made. The combination of these advances has allowed continual improvement in Schottky diode p-n junction, MESFET, MOSFET, HBT, and LED devices 相似文献

Over the last 40 years in the semiconductor industry, one of the most reliable truths has been that "thepath forward is through integration." Moore's law and its various derivatives and cousins have illustrated how greater integration has provided tremendous benefits in cost, power, size, and performance. While shrinking process lithography has been a critical enabler of this trend, we should remember that tremendous innovation in device technology, circuits, system architecture, computer aided design (CAD), packaging, and many other areas have been necessary as well. The exponential integration phenomenon has not been limited to memory and microprocessors: mixed signal and radio functions have also seen striking advances in integration over the last 20 years, from cell phones to wireless LANs, integrated "systemon-a-chip" (SOC) transceivers have become prevalent in the circuits conferences, journals, and - in some applications - have even made it into commercial mainstream products. 相似文献

The author explains how the kanban, or just-in-time, approach to manufacturing works. He then draw analogies with data communication systems and in particular asynchronous transfer mode and routing switches. These analogies are illuminating in that they show how alike the two disciplines are, and how they have arrived at similar solutions to similar problems. The author studies the differences between the two fields which could lead to communications engineers learning something from the ideas of manufacturing engineers, and vice versa 相似文献
