【正文】 sic form of system produces some: After joining with the database , produce the basic form TCTables and TCColumns of two systems according to the user name linking to each other with the database , TCTables form includes English name , Chinese name and some attribute of form belonging to this user in this database , for instance can revise , can inquire about 。Produce the design of the tool and realize automatically on the basis of JSP webpage It is an important respect that Inter uses that Web develops technology, and JSP is the most advanced technology that Web is developed , it is present Web developer39。s own one, is it is it put up to go again by oneself to need , save construction period in user , facilitate use of user. In this system , classify the page according to the function type , sum up the monly used page type, produce the template storehouse. Storehouse technology of the label In JSP, movements can create and visit the language target of the procedure and influence the element exported and flowed. JSP has defined six standard movements. Except six standard movement these, user can define own movement finish the specific function. These movements are known as the customer movement, they are the reusable procedure module . Through movement these, programmer can some encapsulation stand up too display function of page in JSP page, make the whole page more succinct and easier to maintain. In a JSP page, movements were transfered through the customer label in these customers. And the label storehouse (Tag Library ) is the set of the customer label. JSP label storehouse is that one kind produces the method based on script of XML through JavaBeans. It is one of the greatest characteristics of JSP. Through the label storehouse , can expand JSP application unrestrictedly , finish any plicated application demand. JSP label storehouse has the following characteristic: ① Easy to use: The labels in JSP and general HTML marks are totally the same in appearance, it is as convenient as ordinary HTML mark to use. ② The easy code is paid most attention to: Every label in the label storehouse can finish certain function . Define ready to eat one label storehouse , is it pack one Jar file the label storehouse to need only, then only need use this label storehouse in other systems afterwards, needn39。s best to classify to go on to use, form labels. Do not use and realize this application repeatedly in each label . While revising and perfecting to using like this , only need to revise this label, maintenance of the easy code. (3) Facilitate users39。從原來(lái)的CGI( Common Gateway In- terface)到 ASP( Active Server Page),都從某種程度上滿足了網(wǎng)頁(yè)開(kāi)發(fā)人員對(duì)動(dòng)態(tài)網(wǎng)頁(yè)開(kāi)發(fā)技術(shù)的需求。 作為一種基于文本的、以 顯示為中心的開(kāi)發(fā)技術(shù), JSP 提供了 Java Servlet的所有好處。生成內(nèi)容的邏輯被封裝在標(biāo)識(shí)和 JavaBeans 組件中,并且捆綁在小腳本中,所有的腳本在服務(wù)器端運(yùn)行。 系統(tǒng)設(shè)計(jì)目標(biāo)和使用的主要技術(shù): ( 1)設(shè)計(jì)目標(biāo) 本系統(tǒng)的設(shè)計(jì)目標(biāo)是為只懂得 HTML 但完全不了解 JSP 的一般網(wǎng)頁(yè)開(kāi)發(fā)人員提供一個(gè)網(wǎng)頁(yè)開(kāi)發(fā)工具,使他們能夠根據(jù)系統(tǒng)文檔,通過(guò)標(biāo)簽使用 JSP 的常用功能,最后生成一個(gè)只包含靜態(tài) HTML 和 JSP 標(biāo)簽的動(dòng)態(tài) JSP 網(wǎng)頁(yè)。這些動(dòng)作被稱(chēng)為客戶化動(dòng)作,它們是可重用的程序模塊。 ② 易于代碼重用:標(biāo)簽庫(kù)中的每一個(gè)標(biāo)簽都能完成一定的功能。 系統(tǒng)的組成和實(shí)現(xiàn): ( 1)系統(tǒng)組成 本系統(tǒng)主要由四個(gè)部分組成 : 數(shù)據(jù)庫(kù)連接部分:本系統(tǒng)支持常用的幾個(gè)數(shù)據(jù)庫(kù),包括 Oracle、 Sybase、MSSQLServer、 MySQL 和 DB2,根據(jù)用戶選擇的數(shù)據(jù)庫(kù)類(lèi)型和用戶提供的數(shù)據(jù)庫(kù)名稱(chēng)、用戶名、密碼使用 JDBC 同數(shù)據(jù)庫(kù)相連。當(dāng)處理程序遇到模板中的標(biāo)簽時(shí),就為用戶提供交互界面,讓用戶為指定的標(biāo)簽輸入?yún)?shù),并由系統(tǒng)驗(yàn)證用戶輸入的標(biāo)簽的有效性。 1)在標(biāo)簽中應(yīng)該盡量少的包含靜態(tài)的 HTML。 3)方便用戶的使用。 <%@ taglib uri=“ tag. tld” prefix=“ ctag”%> 其中 uri 指定標(biāo)簽庫(kù)描述文件的路徑; prefix 指定引用標(biāo)簽時(shí)所使用的前綴。在以后可以考慮為用戶提供接口,使用戶可以自己擴(kuò)充模板庫(kù)和標(biāo)簽庫(kù),進(jìn)一步增強(qiáng)系統(tǒng)的功能。 Java 是未來(lái)開(kāi)發(fā)語(yǔ)言的主流,而 Java 在 Web 上的主要應(yīng)用 JSP 也必將成為未來(lái) Web 開(kāi)發(fā)的主流技術(shù)。 ② 標(biāo)簽的實(shí)現(xiàn):一個(gè)標(biāo)簽就是一個(gè)特殊的 Java 類(lèi),這個(gè)類(lèi)必須繼承TagSupport 類(lèi),這個(gè)類(lèi)是在 javax. servlet. jsp. tagext 包中定義的。 2)盡量提高代碼的重用度。如果用戶對(duì)頁(yè)面的靜態(tài)方面的效果不太滿意,用戶可以通過(guò)代碼查看修改窗口修改代碼中的 HTML 代碼。 模板選擇和網(wǎng)頁(yè)生成部分:該部分是系統(tǒng)的核心部分。通過(guò)這種統(tǒng)一維護(hù)方式,不用在每個(gè)網(wǎng)頁(yè)上去作修改,極大地減少了維護(hù)的工作量,節(jié)約了維護(hù)成本。 JSP 標(biāo)簽庫(kù)是一種通過(guò) JavaBeans 生成基于 XML 的腳本的方法。在本系統(tǒng)中,將頁(yè)面按照功能類(lèi)型進(jìn)行分類(lèi),歸納出常用的頁(yè)面類(lèi)型,生成模板庫(kù)?;诮M件的方法加速了總體的開(kāi)發(fā)過(guò)程,極大地提高了項(xiàng)目整體開(kāi)發(fā)的效率。這就可以用帶 Java 類(lèi)的 JSP 頁(yè)面來(lái)定 義 Web 模板,以建立一個(gè)具有相似外觀的頁(yè)面組成的網(wǎng)站。 JSP 是由 Sun MicroSystem公司于 1999年 6月推出的新的網(wǎng)頁(yè)開(kāi)發(fā)技術(shù),它是基于 Java Serv- let 以及整個(gè) Java 體系的 Web 開(kāi)發(fā)技術(shù),是 Servlet2. 1API 的擴(kuò)展。 It is the parameter assignment of the label.
