【正文】 四年之前，我們帶著無比的憧憬，投身于大學(xué)的學(xué)習(xí)中來，四年后，盡管我們帶著戀戀的不舍，卻不得不告別大學(xué)校園，走向社會(huì)。 測試結(jié)果 ： 用戶名 檢測結(jié)果 暖暖 刪除成功 測試編號(hào)： 13 測試項(xiàng)目：用戶或管理員的修改功能 測試目的：用戶或管理員登錄測試是能正常地進(jìn)行用戶或商品修改，檢查系統(tǒng)是否能對(duì)數(shù)據(jù)庫進(jìn)行檢索并給出提示 正確的步驟： (1) 打開產(chǎn)品瀏覽頁面或訂單頁面等，在相應(yīng)的功能欄中測試修改功能。 圖 銷售排行管理界面 22 3 特價(jià)商品管理模塊 通過頁面可以看出，用戶可以瀏覽特價(jià)商品，特價(jià)商品屬于超低價(jià)商品，這塊是特地為特定的客戶設(shè)計(jì)的，因?yàn)樵趯?shí)體店客戶有分各個(gè)等級(jí)，比如：柏鉆、金鉆、銀鉆等等，不同的客戶享受的價(jià)格和服務(wù)是不一樣的，所以如果是實(shí)體店的高級(jí)會(huì)員就能通過網(wǎng)站購買這種特價(jià)汽車。連接數(shù)據(jù)庫，打開用戶數(shù)據(jù)表 users，檢驗(yàn) 用戶登錄信息。 管理員信息表 字段序號(hào) 字段名稱 類型 主鍵 /外鍵 說明 1 managerId int 主鍵 管理員編號(hào) 2 account nvarchar(50) 賬戶 3 Password nvarchar(50) 密碼 4 name nvarchar(50) 戶名 管理員信息表是用來記錄注冊(cè)用戶的基本信息的，方便管理整個(gè)網(wǎng)站管理員情況的查看，包括：管理員編號(hào)，賬戶，密碼類型。 (6)預(yù)約設(shè)置功能 系統(tǒng)中，當(dāng)有客戶提交預(yù)約申請(qǐng)后，管理員可以在這里設(shè)置預(yù)約的成功與否。 (5)用戶信息查詢功能 用戶購物車信息查詢：用戶對(duì)自己要購買的已預(yù)先放入購物車內(nèi)產(chǎn)品進(jìn)行查詢。從而滿 足消費(fèi)者的需求、降低庫存壓力，降低成 9 本，縮短交貨周期，給消費(fèi)者帶來實(shí)惠和快捷，使企業(yè)獲得豐厚的利益的“雙贏”的格局。 (3) Web 服務(wù)器 Tomcat 在本系統(tǒng)中我們選用版本 進(jìn)行開發(fā)。同樣，軟件工程師使用 Struts 為業(yè)務(wù)應(yīng)用的每一層提供支持。類似于 Sun39。目前網(wǎng)上流傳相當(dāng)豐富且全面的開發(fā)工具方面的外掛程式，但是 My Eclipse 已經(jīng)超越了開發(fā)環(huán)境的概念，可以想象My Eclipse 將成為未來的整合的桌面環(huán)境。汽車正影響我們的生活，汽車正改變我們的生活。它改善了我們的活動(dòng)空間，提高了我們的生活質(zhì)量，縮小了空間的距離，推動(dòng)了社會(huì)的文明進(jìn)步。 (5)用戶信息查詢功能 用戶購物車信息查詢：用戶對(duì)自己要購買的已預(yù)先放入購物車內(nèi)產(chǎn)品進(jìn)行查詢。 2. 用戶界面的美觀，操作方便。 二、 課題研究的內(nèi)容 前臺(tái)用戶功能： (1)用戶注冊(cè)功能 用戶要訪問書柜必須先行注冊(cè)。 (2)用戶管理功能 本功 能主要是對(duì)全部注冊(cè)用戶進(jìn)行管理和對(duì)密碼的修改。 關(guān)鍵詞： 網(wǎng)上汽車 JAVA Eclipse MYSQL Abstract Car is the crystallization of human civilization. As people39。前期的資金主要用于購置設(shè)備，建立信息中心，實(shí)行統(tǒng)一購置與管理，設(shè)備的購買根據(jù)使用即可原則，及時(shí)的反饋用戶和市場信息。當(dāng) JAVA 字節(jié)碼進(jìn)入解釋器時(shí)，首先必須經(jīng)過字節(jié)碼校驗(yàn)器的檢查，然后 JAVA 解釋器將決定程序中類的內(nèi)存布局，隨后，類裝載器負(fù)責(zé)把來自網(wǎng)絡(luò)的類裝載到單獨(dú)的內(nèi)存區(qū)域，避免應(yīng)用程序之間相互干擾破壞。使用 Struts 的目的是為了幫助我們減少在運(yùn)用 MVC 設(shè)計(jì)模型來開發(fā) Web 應(yīng)用的時(shí)間。 Model 1 架構(gòu)單 純編寫比較容易，但在 Model 1 中 JSP 可能同時(shí)肩負(fù) View 與 Controller 角色，兩類程序代碼有可能混雜而不易維護(hù)。數(shù)據(jù)庫采用 MY SQL 數(shù)據(jù)庫，具有高安全性，并且集成比較好，很合適用于 Windows應(yīng)用的后臺(tái)數(shù)據(jù)庫。 (1)用戶注冊(cè)功能 10 用戶要訪問書柜必須先行注冊(cè)。 (1)管理員登錄功能 用戶信息輸入錯(cuò)誤會(huì)出現(xiàn)相關(guān)提示，為了增加用戶密碼的安全性，登錄界面對(duì)用戶密碼進(jìn)行 MD5 加密。每一個(gè)購物車，只會(huì)生成一項(xiàng)訂單，購物車與訂單之間是一對(duì)一的關(guān)系。用戶通過表單提供用戶名、密碼信息，系統(tǒng)根據(jù)用戶提供的登錄信息對(duì)用戶進(jìn)行身份查詢鑒別。或點(diǎn)擊“重置”按鈕，重新輸入。 (2) 選擇“提交”按鈕，等待系統(tǒng)提示。在開發(fā)過程中，認(rèn)真調(diào)查分析了用戶的需求，及時(shí)準(zhǔn)備了詳細(xì)的文檔資料，這讓我在開發(fā)過程中少走了許多彎路。四年來，有多少可敬的師長、同學(xué)、朋友給了我無言的幫助，在這里請(qǐng)接受我誠摯的謝意 !我的師長、我的領(lǐng)導(dǎo)、我的同學(xué)給予我的關(guān)心和幫助，使我終身收益，我真心地感謝 他們 ，也感謝培育我四年的母校 ! 37 附錄：英文資料翻譯 英文原文 JSP application frameworks What are application frameworks: A framework is a reusable, semiplete application that can be specialized to produce custom applications [Johnson]. Like people, software applications are more alike than they are different. They run on the same puters, expect input from the same devices, output to the same displays, and save data to the same hard disks. Developers working on conventional desktop applications are accustomed to toolkits and development environments that leverage the sameness between applications. Application frameworks build on this mon ground to provide developers with a reusable structure that can serve as the foundation for their own products. A framework provides developers with a set of backbone ponents that have the following characteristics: are known to work well in other applications. 2. They are ready to use with the next project. 3. They can also be used by other teams in the anization. Frameworks are the classic buildversusbuy proposition. If you build it, you will understand it when you are done— but how long will it be before you can roll your own? If you buy it, you will have to climb the learning curve— and how long is that going to take? There is no right answer here, but most observers would agree that frameworks such as Struts provide a significant return on investment pared to starting from scratch, especially for larger projects. Other types of frameworks: The idea of a framework applies not only to applications but to application 38 ponentsas well. Throughout this article, we introduce other types of frameworks that you can use with Struts. These include the Lucene search engine, the Scaffold toolkit, the Struts validator, and the Tiles tag library. Like application frameworks, these tools provide semiplete versions of a subsystem that can be specialized to provide a custom ponent. Some frameworks have been linked to a proprietary development environment. This is not the case with Struts or any of the other frameworks shown in this book. You can use any development environment with Struts: Visual Age for Java, JBuilder, Eclipse, Emacs, and Textpad are all popular choices among Struts developers. If you can use it with Java, you can use it with Struts. Enabling technologies: Applications developed with Struts are based on a number of enabling ponents are not specific to Struts and underlie every Java web application. A reason that developers use frameworks like Struts is to hide the nasty details behind acronyms like HTTP, CGI, and JSP. As a Struts developer, you don’t need to be an alphabet soup guru, but a working knowledge of these base technologies can help you devise creative solutions to tricky problems. Hypertext Transfer Protocol (HTTP): When mediating talks between nations, diplomats often follow a formal protocol. Diplomatic protocols are designed to avoid misunderstandings and to keep negotiations from breaking down. In a similar vein, when puters need to talk, they also follow a formal protocol. The protocol defines how data is transmitted and how to decode it once it arrives. Web applications use the Hypertext Transfer Protocol (HTTP) to move data between the browser running on your puter and the application running on the server. Many server applications municate using protocols other than HTTP. Some of these maintain an ongoing connection between the puters. The application server knows exactly who is connected at all times and can tell when a connection is dropped. Because they know the state of each connection and the identity of each person using it, these are known as stateful protocols. By contrast, HTTP is known as a stateless protocol. An HTTP server
