摘要
 
 電子郵件是Internet應(yīng)用服務(wù)之一，也是使用最多的互聯(lián)網(wǎng)服務(wù)。電子郵件系統(tǒng)通過(guò)Internet，實(shí)現(xiàn)各類信息的傳送、接受貯存等處理，將郵件傳送到世界的各個(gè)角落。電子郵件系統(tǒng)經(jīng)過(guò)幾十年的發(fā)展，已經(jīng)形成了完善的技術(shù)體系。用戶最初只能通過(guò)Outlook，F(xiàn)oxmail等客戶端軟件來(lái)收發(fā)自己的郵件，但單純的客戶端程序進(jìn)行郵件的收發(fā)已經(jīng)不能滿足用戶移動(dòng)辦公的需要。Web郵件技術(shù)的出現(xiàn)，徹底解決了用戶辦公的需要，其快捷、方便的優(yōu)點(diǎn)吸引了眾多的網(wǎng)絡(luò)用戶。用戶無(wú)須安裝任何Email客戶端軟件，只需使用瀏覽器打開(kāi)放在服務(wù)器上的特定網(wǎng)頁(yè)即可進(jìn)行Email收發(fā)及相關(guān)操作。
 J2EE、AJAX技術(shù)等新的Web技術(shù)的層出為郵件系統(tǒng)的更新帶來(lái)了巨大的突破。本文著重闡述了實(shí)現(xiàn)基于J2EE的Hibernate技術(shù)和AJAX技術(shù)的Web郵件系統(tǒng)的理論基礎(chǔ)、設(shè)計(jì)思想、系統(tǒng)架構(gòu)、開(kāi)發(fā)過(guò)程以及對(duì)以上內(nèi)容的總結(jié)與展望。論文前半部分著重論述了Hibernate、AJAX和JavaMail 郵件技術(shù)，闡釋了電子郵件系統(tǒng)的工作原理及郵件傳送過(guò)程，探尋如何開(kāi)發(fā)郵件服務(wù)。簡(jiǎn)單介紹了與郵件系統(tǒng)相關(guān)的幾個(gè)重要協(xié)議。熟悉按照這些協(xié)議、規(guī)范進(jìn)行的電子郵件的傳送過(guò)程。論文后半部分是對(duì)系統(tǒng)的各個(gè)模塊進(jìn)行分析、設(shè)計(jì)和編碼。包括系統(tǒng)整體設(shè)計(jì)思想，模塊設(shè)計(jì)思想以及各功能模塊實(shí)現(xiàn)的流程圖等。最后對(duì)該郵件系統(tǒng)進(jìn)行了總結(jié)和展望。

ABSTRACT
 
 Email is one of Internet applications and also the service users use most. Electronic Mail System fulfills transmission, receiving, storing management of all kinds of signals through Internet which connects the whole world, sending mails to every corner of the world. With many years' development, Email System has formed consummate technology architecture. Users can only use client softwares such as Outlook, Foxmail to receive and send their own mails at first, but this can't satisfy the requirement of users' moving office. With the appearance of Web Mail technique, the problem has been completely solved. Many network users are attracted by its advantages of speediness and convenience. Users can implement Email receiving, Email sending and so on by opening certain Web pages on Servers through Browsers without installing any Email Client softwares.
 The layer of the new Web technique of the J2EE, AJAX technique ..etc. for mail system of renewal bring huge of break. This paper emphasizes expatiating on the implementation of Web Mail system based on the Hibernate of J2EE platform and AJAX , including their theory foundation, design idea, system structure, development process, sum-up and expectation of all above. The first half part of the paper discusses the Hibernate and the AJAX architecture and JavaMail mail technique, explaining the work principia of Email system and the transmission process of Email, exploring how these technologies use JavaMail API to provide standard mail service. Then the paper simply introduces several important protocols correlative with mail system and comprehends the transmission process of Email according to these protocols and  criterions. The other half part of this paper sets forth analyse, design and coding of  each module in the mail system, including system's whole design idea, modules' design idea, implementation flow chart of each module, etc. In the end, the summarization of the Web Mail system is simply discussed in this paper.
