4、 l _Toc28973 參考文獻(xiàn) PAGEREF _Toc28973 45-. z.課程設(shè)計(jì)概述1.1問題描述隨著計(jì)算機(jī)網(wǎng)絡(luò)日新月異的開展，人們的交流方式越來越多，傳統(tǒng)的交流方式，如：信件、電報(bào)、等已經(jīng)難以滿足人們的交流要求，在互聯(lián)網(wǎng)上即時(shí)的和好友取得聯(lián)系，已經(jīng)成為當(dāng)今社會(huì)人們主流的聯(lián)系方式。因此，兩臺(tái)計(jì)算機(jī)之間進(jìn)展即時(shí)通訊、發(fā)送文件等交流方式已經(jīng)成為必然潮流。因此出現(xiàn)了等聊天工具，然而等聊天工具雖然方便、實(shí)用，但是，娛樂功能太多，有很多吸引人的娛樂功能，從一定程度上來說，是一種娛樂工具，不能作為用于即時(shí)通訊、文件共享的專用工具。目前，用于實(shí)現(xiàn)單一的即時(shí)通訊、文件共享的軟件實(shí)在太少，而且，它

5、們局部都是絕對的C/S模式，對遠(yuǎn)程效勞器有非常大的依賴性，沒有徹底實(shí)現(xiàn)點(diǎn)對點(diǎn)的交流。為此，我決定開發(fā)一個(gè)專用于實(shí)現(xiàn)兩臺(tái)計(jì)算機(jī)之間即時(shí)通訊、文件共享的軟件，以方便兩臺(tái)計(jì)算機(jī)之間信息的交流。防止了效勞器忙或與效勞器無法連接時(shí)，浪費(fèi)過多時(shí)間用于和效勞器建立連接。因此，這個(gè)軟件是極具適應(yīng)性和實(shí)用性的即時(shí)通訊軟件。1.2功能需求分析實(shí)現(xiàn)網(wǎng)絡(luò)聊天的功能，采用WindowsSocket或JavaSocket編程，效勞器與客戶端采用了TCP/IP連接方式，在設(shè)計(jì)聊天方案時(shí)，可將所有信息發(fā)往效勞器端，再由效勞器進(jìn)展處理，效勞器端是所有信息的中心。效勞器端要保存用戶信息，可利用數(shù)據(jù)庫來實(shí)現(xiàn)這一功能，需要建立用戶信

6、息數(shù)據(jù)庫。在客戶端可采用文件系統(tǒng)保存聊天紀(jì)錄和用戶?？赏ㄟ^閃動(dòng)托盤圖標(biāo)和播放不同的音樂提示信息到來及好友上線等信息?？赏ㄟ^建立消息鏈表來保存用戶接收的各種消息。1.3環(huán)境需求分析運(yùn)行環(huán)境：Windows 9*、2000、*P、Windows 7必要環(huán)境：JDK 1.6以上、eclipse開發(fā)環(huán)境硬件環(huán)境：CPU 400MHz以上,存512MB以上學(xué)生信息管理系統(tǒng)軟件總體設(shè)計(jì)2.1整體思路該C/S模式的聊天系統(tǒng)，就是效勞器來提供效勞端連接響應(yīng)，客戶端主動(dòng)的發(fā)起連接請求。當(dāng)多個(gè)用戶同時(shí)連接到效勞器時(shí)，經(jīng)由效勞器的接收與轉(zhuǎn)發(fā)便可以實(shí)現(xiàn)客戶之間的通信。對于整體系統(tǒng)的流程，也是分為兩局部，即客戶端的發(fā)起

7、請求，效勞器響應(yīng)請求。首先是客戶端的登陸，客戶端在登陸時(shí)，必須設(shè)置所想要連接的效勞器，然后客戶端就會(huì)根據(jù)設(shè)置的效勞器IP地址，向效勞器發(fā)起建立連接請求。而效勞器端是始終在監(jiān)聽網(wǎng)絡(luò)狀態(tài)的，主要檢測到有一個(gè)連接請求，則效勞器就會(huì)給當(dāng)前的發(fā)起端分配一個(gè)效勞線程，用于處理它的各種請求。對于客戶端的各種請求，實(shí)際上都是通過在客戶發(fā)往效勞器的各種字符流區(qū)分的，具體的方法就是在消息的頭部以及尾部添加特殊字符串，從而實(shí)現(xiàn)效勞器對消息請求的識別。比方對于登陸信息，消息的頭部就是PEOPLO,而對于私聊中的消息，頭部就是SEC,其他的同理都添加了頭部。當(dāng)然，對于客戶端來說，這些都是透明的，用戶的操作并沒有受到任何

8、影響。在效勞器端，消息被檢測分析后，變回根據(jù)具體的目的進(jìn)展處理，比方是私聊消息，效勞器便會(huì)根據(jù)其尾部的目的信息，向目標(biāo)端轉(zhuǎn)發(fā)該條消息。這里額外要說的是，該系統(tǒng)特別的對用戶發(fā)來的消息進(jìn)展了加密處理，即用戶的各種具體信息，不僅能夠防止向第三方的泄漏，而且即使效勞器端出現(xiàn)異常，信息也不會(huì)泄漏。對于私聊的方式，該系統(tǒng)所采用的方法類似于QQ的通信方式，由發(fā)起方主動(dòng)連接，當(dāng)目的方接收到連接請求后，會(huì)主動(dòng)建立一個(gè)私聊窗口，從而 實(shí)現(xiàn)私聊。2.2總體設(shè)計(jì)流程圖ServerClient建立效勞器監(jiān)聽socket建立連接創(chuàng)立socket向效勞器發(fā)請求等待并接收連接請求接收請求后創(chuàng)立socket連接InputStr
