局域網(wǎng)即時(shí)聊天軟件設(shè)計(jì)與實(shí)現(xiàn)-畢業(yè)論文（附詳細(xì)源代碼）

1、I摘要即時(shí)通信在互聯(lián)網(wǎng)領(lǐng)域的應(yīng)用取得了巨大的成功，但在學(xué)校﹑企業(yè)內(nèi)部的應(yīng)用仍遠(yuǎn)未普及。鑒于即時(shí)通訊作為一項(xiàng)有廣泛應(yīng)用價(jià)值的技術(shù)框架，在逐步適應(yīng)企業(yè)網(wǎng)絡(luò)﹑教育網(wǎng)絡(luò)的應(yīng)用特點(diǎn)后，局域網(wǎng)即時(shí)通信必將取得和電子郵件一樣的普及效果。該系統(tǒng)使用Myeclipse作為開(kāi)發(fā)平臺(tái)﹑MysqL數(shù)據(jù)庫(kù)存儲(chǔ)用戶(hù)信息和聊天記錄，用套接字連接客戶(hù)端和服務(wù)器，用數(shù)據(jù)包套接字發(fā)送消息。本系統(tǒng)采用CS模式構(gòu)建，由客戶(hù)端和服務(wù)器組成?？蛻?hù)端只要填寫(xiě)服務(wù)器的IP地址和通信端

2、口號(hào)，并通過(guò)所分配的賬號(hào)，就可以登陸和使用。服務(wù)器與MysqL數(shù)據(jù)庫(kù)可部署在同一網(wǎng)段的任一節(jié)點(diǎn)上，通過(guò)接受客戶(hù)端不同請(qǐng)求而對(duì)數(shù)據(jù)庫(kù)進(jìn)行增加﹑刪除、修改、查找的操作，這樣就可以方便的進(jìn)行維護(hù)并前保證了同一局域網(wǎng)信息的安全和網(wǎng)絡(luò)資源的充分利用，并且最大程度的保證了數(shù)據(jù)庫(kù)的安全性。使用該系統(tǒng)可進(jìn)行一般的文字交流，添加好友等功能。關(guān)鍵詞關(guān)鍵詞：Myeclipse；Socket；多線程；MysqL數(shù)據(jù)庫(kù)；TCPIP協(xié)議III目錄前言.......
