【正文】 畢業(yè)論文（畢業(yè)設計）題目 ：android 即時通訊軟件系 院： 計算機軟件學院學生姓名：盧豐學 號： 0908143503專 業(yè)：計算機應用(智能產品設計)年 級： 計應 095完成日期： 指導教師： 余永佳摘 要在網絡越來越發(fā)達的今天，人們對網絡的依賴越來越多，越來越離不開網絡，由此而產生的聊天工具越來越多，例如，國外的 ICQ、國內騰訊公司開發(fā)的 OICQ。基于 Java 網絡編程的強大功能，本次畢業(yè)設計使用 Java 編寫一個運行在 版本以上的即時通訊軟件。 一般來說，聊天工具大多數(shù)由客戶端程序和服務器程序外加服務器端用于存放客戶數(shù)據(jù)的數(shù)據(jù)庫組成，本系統(tǒng)采用客戶端/服務器架構模式通過 Java 提供的 Socket 類來連接客戶機和服務器并使客戶端和服務器之間相互通信，由于聊天是多點對多點的，Java 提供的多線程功能用多線程可完成多點對多點的聊天，數(shù)據(jù)庫管理系統(tǒng)用 SQL Server2022 完成并通過 訪問數(shù)據(jù)庫。本系統(tǒng)建立在 JAVA 平臺上，系統(tǒng)的設計使用了面向對象技術和面向對象的設計原則。系統(tǒng)采用 C/S 結構，客戶端與客戶端以及客戶端與服務器端之間通過 Socket 傳送消息。使用 JAVA 語言編寫，開發(fā)工具采用 Eclipse。服務器端設計與實現(xiàn)過程中，采用了多線程技術，可以在單個程序當中同時運行多個不同的線程，執(zhí)行不同的任務。大大增強了程序對服務器資源的利用。即時通訊系統(tǒng)完成后將可進行多人對多人的聊天，對好友進行添加、刪除，對新用戶的注冊，發(fā)送消息、接受消息等等功能。關鍵字：多線程 ；客戶機/服務器 ；JAVA ； Socket ； Eclipse ； TCP/IPAbstractas the work bee more and more developed, people bee more and more lean to the work, and can not leave with out it. This caused the chat materials bee more numerous, as the overseas ICQ system, the OICQ system that invented by Tencent Co., and so on. So we create a work chat medium just like the . Java work programming based on the power, the use of Java designed to prepare graduates a chat system.In general, the majority of the chat tool for client and server program in addition to serverside storage of customer data for the database, the system uses a client / server architecture model the adoption of Java provided Socket class connect client and server and between the client and server municate with each other, as the chat is to provide pointtomultipoint and multithreaded Java function to be pleted by using multithreaded chat and more pointtomultipoint, database management system with SQL Server2022 the pletion and adoption of JDBCODBC Bridge access the database.The system built on the JAVA platform, the system design using objectoriented technology and objectoriented design principles. System uses the C / S structure, client and clientside and serverside client and send messages through Socket. The use of JAVA language, development tools using Eclipse. Design and Implementation of serverside process, the use of multithreading technology, which can process in a single run at the same time a number of different threads, the implementation of different tasks. Procedures greatly enhanced the use of server resources.Chat system will allow people to plete chat to more friends，and the system can add, delete somebody，can deal with new user registration, send messages, receive messages and so on.
