【正文】 ult by HTML the browser. This both are helpful in the author protects ow n code, and can guarantee a ny based on the HTML Web browser39。s development needs Java Servlet and the JSP coordination can plete. JSP had the Java te chnology simply easy to use, plete objectoriented, had the platform independency, and safe reliable, mainly faced Inter39。s all characteristics. 2 JSP puting technique To carry on the dynamic website conveniently fast the development, JSP has made the improvement in the following several aspects, causes it to bee builds the cross platform fast the dynamic website first choice plan. carries on the content production and the demonstration separates With the JSP technology, the Web page development personnel may use HTML or the XML marking design and the formatted final page, and uses the JSP marking or the tootsy produces on page39。s plete usability. may entrust with heavy responsibility the module The overw helming majority JSP page relies on may entrust with heavy responsibility, the cross platform module (JavaBeans or Enterprise the JavaBeans module) carries out plex processing which the application procedure requests. The development personnel can share and exchange the execution ordinary operation the module, or causes these modules uses for more users and the customer association. Has ac celerated the overall development process based on module39。 This is other plugin unit39。 Web MVC and Spring Web have provided Java the Web application frame or carries on the integration with other popular Web frame. That is may a both use, achieve both own characteristic carries on supplementary. Structs is the kind w hich, servlet and the JSP mark a group cooperates mutually, they pose the MVC 2 designs w hich may entrust with heavy responsibility. This definition expressed that Struts is a frame, but is not a storehouse, but Struts has also contained the rich mark storehouse and the independence in this frame work utility program class. Client browser (customer browser), the request founds an event from customer browser39。s client is ActionServlet, it knows nothing about to our concrete service class connection. Therefore, Struts has provided a service connection w hich it can understand, namely Action. Through expands Action, we cause our service connection and the Struts service connection maintain patible. 5 CSS synopsis The CSS edition method is the same with HTML, may also be any text editor or the homepage edition software, but also has uses for to edit CSS specially the software. If you write the CSS sentence regards the exterior cascading style sheet, but transfers in the HTML document, then its extension saves .css to be possible. Initially the technical personnel found out HTML, mainly stresses on the definition content, for instance expressed that a paragraph, indicates the title, but excessively has not designed HTML the typesetting and the contact surface effect. Along with the Inter rapid development, HTML is widely applied, the surfer people hoped certainly that the homepage makes attractive, therefore the HTML typesetting and the contact surface effect39。s script language is quite many, script language execution generally only with concrete explanation actuator related, so long as therefore on the system has the corresponding language interpreter to be possible to achieve the cross platform. Script (Script), is includes order and so on bind and alias sets, you may save this set are an independent document then in the time w hich needs carries out, like this may facilita te you in the CS use. The script may save for the suffix named .cfg document places under the cstrike folder, w hen execution in control bench input: exec (script filename) .cfg then. For instance saves a script is the document, inputs in the control bench: may realize the function w hich we need. Must realize an order, so long as is good this process definition (alias), and assigns a key position for this order, so long as later according to will assign the good key position, may realize this process. All scripts are realize through this method. JSP 及其 WEB 技術(shù) 譯文: 1 JSP 簡(jiǎn)介 JSP( JavaServer Pages)是一種基于 Java 的腳本技術(shù)。在 JSP 的眾多優(yōu)點(diǎn)之中,其中之一是它能將 HTML 編碼從 Web 頁(yè)面的業(yè)務(wù)邏輯中有效地分離出來(lái)。 JSP 技術(shù)使用 Java 編程語(yǔ)言編 寫(xiě)類 XML 的 tags 和 scriptlets,來(lái)封裝產(chǎn)生動(dòng)態(tài)網(wǎng)頁(yè)的處理邏輯。插入的 Java 程序段可以操作數(shù)據(jù)庫(kù)、重新定向網(wǎng)頁(yè)等,以實(shí)現(xiàn)建立動(dòng)態(tài)網(wǎng)頁(yè)所需要的功能。 Java Servlet 是 JSP 的技術(shù)基礎(chǔ),而且大型的 Web 應(yīng)用程序的開(kāi)發(fā)需要 Java Servlet 和 JSP 配合才能完成。生成內(nèi)容的邏輯被封裝在標(biāo)識(shí)和 JavaBeans 組件中,并且捆綁在腳本中,所有的腳本在服務(wù)器端運(yùn)行。 可重用組件 絕大多數(shù) JSP 頁(yè)面依賴于可重用的、跨平臺(tái)的組件( JavaBeans 或者 Enterprise JavaBeans 組件)來(lái)執(zhí)行應(yīng)用程序所要求的復(fù)雜的處理。 JSP 技術(shù)封裝了許多功能,這些功能是在易用的、與 JSP 相關(guān)的 XML 標(biāo)識(shí)中進(jìn)行動(dòng)態(tài)內(nèi)容生成所需要的。 數(shù)據(jù)庫(kù)連接 Java 中連接數(shù)據(jù)庫(kù)的技術(shù)是 JDBC, Java 程序通過(guò) JDBC 驅(qū)動(dòng)程序與數(shù)據(jù)庫(kù)相連,執(zhí)行查詢、提取數(shù)據(jù)等操作。這使得 Web 頁(yè)面開(kāi)發(fā)人員能夠使用熟悉的工具和如同標(biāo)識(shí)一樣的執(zhí)行特定功能的構(gòu)件來(lái)進(jìn)行工作。它不斷增長(zhǎng)的可用重構(gòu)和代碼生成功能集合允許您在更高的級(jí)別上操作代碼,并自動(dòng)化通常的 代碼密集型任務(wù)和易錯(cuò)任務(wù)。事實(shí)上,使用由 Eclipse 本身提供的工具能夠超越 Java 開(kāi)發(fā),可擴(kuò)展現(xiàn) 有 Eclipse 應(yīng)用程序,或者甚至創(chuàng)建全新的應(yīng)用程序。在 Eclipse 中,甚至最基礎(chǔ)的功能,比如查找和啟動(dòng)安裝的插件,都封裝在插件中。這是其他插件的工作。 4 Structs 功能簡(jiǎn)介 Struts 是一個(gè) MVC 框架( Framework) ,用于快速開(kāi)發(fā) Java Web 應(yīng)用。就是說(shuō)可將兩者一起使用,達(dá)到將兩者自身的特點(diǎn)進(jìn)行互補(bǔ)。Web 容器將用一個(gè) HTTP 響應(yīng)作出響應(yīng)。 業(yè)務(wù)邏輯 ,業(yè)務(wù)邏輯更新模型的狀態(tài),并幫助控制應(yīng)用程序的流程。ActionForm bean 在會(huì)話級(jí)或請(qǐng)求級(jí)表示模型的狀態(tài),而不是在持久級(jí)。標(biāo)記是使 Struts 有別于其他框架(如 Velocity)的因素之一。 ActionForm 是一個(gè)抽象類,必須為每個(gè)輸入表單模型創(chuàng)建
