【正文】 WEB服務(wù)：。MySQL軟件采用了GPL。第二節(jié) 主要開發(fā)技術(shù)一、Struts2簡介Struts是Apache 基金會Jakarta 項目組的一個Open Source 項目，它采用MVC模式，能夠很好地幫助java 開發(fā)者利用J2EE開發(fā)Web應(yīng)用。編寫Action類后，開發(fā)者還必須在配置文件中配置Action參數(shù)。這樣便通過了Hibernate 實現(xiàn)關(guān)系數(shù)據(jù)庫的持久化操作。②面向切面的編程：Spring框架的另一個核心特色是AOP(Aspectoriented programming，面向切面的編程)。員工工作效率低。圖32功能模塊②子模塊介紹（1)卡號管理設(shè)計：該模塊主要管理員新建用戶，修改密碼，以及給用戶充值，調(diào)用該模塊進(jìn)行操作，并將結(jié)果存入數(shù)據(jù)庫。：圖34信息管理（3)用戶消費信息：該模塊主要實現(xiàn)用戶對自己信息的管理，包括查詢余額消費信息，修改密碼等，用戶進(jìn)行信息管理，首先輸入用戶信息和相關(guān)請求，系統(tǒng)對用戶信息進(jìn)行驗證；系統(tǒng)與服務(wù)器進(jìn)行連接，系統(tǒng)將用戶信息：密碼、卡號，輸入數(shù)據(jù)庫，數(shù)據(jù)庫對上述客戶信息進(jìn)行驗證，反饋驗證信息，并將結(jié)果顯示給用戶該模塊的流程圖如下35；圖35用戶消費信息(4)注銷退出：該模塊實現(xiàn)用戶下機(jī)自動結(jié)賬，并將新的余額存入數(shù)據(jù)庫，同時刪除此次用戶上機(jī)記錄，然后轉(zhuǎn)到用戶登陸框。圖37服務(wù)器業(yè)務(wù)流程圖網(wǎng)吧計費管理系統(tǒng)客戶端流程圖如圖38：客戶端使用流程為，客戶要使用本系統(tǒng)首先要進(jìn)行登錄，打開終端電腦后會出現(xiàn)客戶端登陸界面，并提示用戶輸入口令，用戶輸入口令后，系統(tǒng)對其進(jìn)行驗證。相對的軟件環(huán)境，主要包括MyEclipse、開發(fā)軟件是免費的，其余的數(shù)據(jù)庫及服務(wù)器軟件均是免費的，系統(tǒng)成本主要集中在本管理系統(tǒng)的開發(fā)與維護(hù)上，對用戶不會造成過重的經(jīng)濟(jì)負(fù)擔(dān)。本系統(tǒng)講盡可能的使用戶從界面上獲得直觀的操作信息，達(dá)到方便、快捷、簡單，不會帶給用戶操作體驗上的困擾綜上所述，開發(fā)本系統(tǒng)對中小型網(wǎng)吧的機(jī)房管理有著很大意義，并且不會帶給用戶過多負(fù)擔(dān)，開發(fā)此系統(tǒng)是可行的。方式二：使用sqlserver專用的驅(qū)動程序(即SQL Server 2000 driver for JDBC)進(jìn)行連接，或稱非jdbcodbc橋連接方式。DatabaseName=Admin。}第五章 系統(tǒng)的詳細(xì)設(shè)計與實現(xiàn)該模塊實現(xiàn)驗證用戶登陸信息。 for(int i=0。客戶輸入合法進(jìn)入用戶主界面的代碼成功實現(xiàn)： ClientMainFrame cmm=new ClientMainFrame(useID)。④該模塊實現(xiàn)用戶對自己密碼修改的功能，首先系統(tǒng)驗證用戶輸入是否為空以及兩次新密碼輸入是否一致，若通過驗證，則修改成功，將該用戶的新密碼代替舊密碼存入數(shù)據(jù)庫。 i++){ s3+= ()[i]。 (str)。//獲得上機(jī)時間與當(dāng)前時間 try { Connection conq=()。 endtime = new ()。 ().setBackground()。 //()。 (new Rectangle(188, 252, 199, 30))。 (new Rectangle(184, 194, 200, 31))。 (new Rectangle(183, 138, 199, 32))。 ().add(jLabel4, null)。測試無處不在，從我們需求分析開始，就開始了這個系統(tǒng)的測試工作。第三節(jié) 系統(tǒng)測試的實施本系統(tǒng)在每完成一個模塊后，都進(jìn)行了相應(yīng)的測試，先進(jìn)行管理員的登錄，測試不同角色的管理員登陸后所展現(xiàn)的功能菜單是否相同。（1） 查詢功能測試測試系統(tǒng)的用戶管理模塊，主要針對電腦主機(jī)，查詢主機(jī)號碼進(jìn)行測試。當(dāng)然系統(tǒng)中也存在很多不足之處，可以在以后版本中進(jìn)行補(bǔ)充和改進(jìn)。致 謝“飲其流時思其源，成吾學(xué)時念吾師。沒有他們的幫助，我是不可能順利完成設(shè)計的。 It is even in one time dialogue course, mutual role also exchanges probably. As in carry out file transmission , if be called as one side who offers file server, is called as one side who gets file customer, when using get or mget order since another node takes file, can think that what self use and it is client puter , is using put or mput order to another node dispatch file can again think the machine that used self is server. Multilayer customer / server structure Along with the development of enterprise application, recently, have again arisen a kind of new multilayer architecture, it applies customer end to divide into two minutes: Customer application and server apply. Customer application is the part of original customer application , is another and partial to have been transfered to server to apply. New customer application takes the responsibility for user interface and simple regular business logic and new server application resident core , changeable business logic. Therefore its structure has bee new ( Client application + Server application )/Server structure. Following picture shows: This kind of structure has solved traditional Client/Server can expand problem, have reduced customer end business logic , and have reduced the requirement of customer end for hardware. At the same time because of a lot of business logic concentrations have gone to unitary application server on, the maintenance work of application system had been also concentrated together, have eliminated the problem in the traditional structure of Client/Server that software distributes. This kind of structure is called as the architecture of B/S. Browser/Server and browser / server hold the architecture of B/S. On essence, Browser/Server is also a kind of structure of Client/Server, it is a kind of from the traditional two levels of structural development of Client/Server e to the threelayer structural special case of Client/Server that applied on Web. In the system of Browser/Server, user can pass through browser to a lot of servers that spread on network to send request. The structure of Browser/Server is maximum to have simplified the work of client puter, on client puter, need to install and deploy few customer end software only , server will bear more work, for database visit and apply program carry out will in server finish. Under the threelayer architecture of Browser/Server, express layer ( Presentatioon ) , function layer ( Business Logic ) , data layer ( Data Service ) have been cut the unit of 3 relative independences: It is the first layer of to express layer: Web browser. In expressing layer contain system show logic, locate in customer end. It39。s task is the request concerning accepting user , need to be first conducted and corresponding to expand application program and database to carry out connection , passes through the waies such as SQL to database server to put forward data handling to apply for, then etc. database server the result of handling data submit to Web server, deliver again by Web server to return customer end. The number of plies of 3th according to layer: Database server. In data layer contain systematic data handling logic, locate in database server end.
