一个年夜略的即时通信工具的计划与开发

摘要

即时通信（Instant Messaging）是今朝Internet上最为风行的通信方法，各类千般的即时通信软件也层出不穷；处事供应商也供应了越来越厚实的通信处事功效。Java是当前对照风行的开发说话之一，它有着自己的易用特点与机能上风，比如跨平台、安适性、多线程、收集Socket编程、数据流观念等方面，是以通过对开源即时通信LinuxQQ的研究和剖析，基于Java说话和J2EE类型计划了一个即时通信工具JICQ (Java for I seek you)，并对其系统结构、构成模块及系统关键妙技举办了剖析与计划。在系统计划与建模历程中，使用了UML 和面向工具的剖析、计划要领，并使用Rose作为建模工具；本系统基于j2se1.5，j2ee1.4，使用Eclipse等作为开发工具，在开发历程顶用到了时下风行的重构开发要领，优化了系统的计划。力争使系统具有安适、高效、适用、撑持在差别系统平台运行等特点。

Design and Development of a Simple Instant Communication Tool

Abstract

Instant Message is currently the most popular way to communicate on the Internet,so various Instant Messaging software are continuously appearing; Service providers offer more and more communication service nowadays. Java programming language (Java 2 Standard Edition) is one of popular programming languages. With its features of cross-platform, security, multi-threaded capability, Socket Programming, data flow concepts and so on, Java has its own distinctive and functional advantages. Therefore, based on the research and analysis of LinuxQQ, with the Java language and J2EE, this paper designs an instant messenger—JICQ (Java for I seek you), and then analyzes its architecture, modules, as well as its key technologies. During the design and modeling process of instant messenger system, the UML and method of object-oriented analysis and design are used. Furthermore, the modeling tool of Rose is included. Based on the system j2se1.5, j2ee1.4, the Eclipse development tool in the development process, and refactoring development method, the system design is optimized. Due to these factors, the system is safe, efficient and practical in different operating system platforms.
