基于Java Socket的高校机房计费管理系统
首发时间:2009-06-18
摘要:本文中所描述的系统使用Java语言,在Jbuilder环境下开发。除了实现基本的计费功能外,系统采用Java Socket编程实现了服务器与客户端的实时通信,这一功能的实现很好的弥补了现有系统的许多缺陷,实现了网络化管理;利用Java多线程技术,将服务器端的一个线程与用户、客户端、机器、用户标识等几个实体对应起来,使服务器的管理可以定位到用户、客户端和机器;利用Java定时器技术实现在线用户的余额管理,用户余额为0时强制断开客户端的连接;利用C++动态连接库技术实现客户端锁屏功能。另外,本系统还具有处理如服务器死机、机房断电等异常的能力。

The Accounting Management System of College computer room based on Java Socket
Abstract:In this paper,the system uses Java programming language and implemented in Jbuilder environment. Besides implementing the basic accounting functions ,the system also uses Java Socket technology to realize the real time communication function between the clients and the server ,which makes up for the existing system’s many shortcomings primly , realizing network management .Using Java multithreading technology to associate a thread of the server with the user, the client ,the computer and the user ID, which makes it is possible to locate a user ,a client or a computer for management; Implementing the balance management of the online users by using the timer technology of Java. It will cut the connection of the client when the user’s balance is zero; Using the dynamic link library technology of C++ to achieve the function of locking the screen of the client computer .In addition ,the system has the ability of handling some exceptions such as the server’s death, the power cut of the room and so on.
