下面是范文網(wǎng)小編整理的學(xué)習(xí)jsp的體會13篇，供大家參閱。

學(xué)習(xí)jsp的體會1

　　不要總對別人說的給個代碼吧!你應(yīng)該多想想如何做，怎么做?當(dāng)你自己想出來再參考別人的提示，你就知道自己和別人思路的差異，這樣才能進(jìn)步。

　　初學(xué)者請不要看太多太多的書，只會紛亂你的心思，先找本好書完整系統(tǒng)的學(xué)，很多人只對部分功能熟悉而已，不系統(tǒng)功能體系上還是不夠的。

　　看幫助,不要因?yàn)楹茈y而自己是初學(xué)者所以就不看;多看的參考手冊，雖然你可能看不懂，總覺得不夠直觀。但這才是最根本的東西。

　　不要被對象、屬性、方法等詞匯所迷惑;最根本的是先了解最基礎(chǔ)知識。

　　要關(guān)注那些細(xì)小的細(xì)節(jié)的問題--他們往往并不那么簡單，為了解決它你可能要用到很多很多的東西，幫你回顧知識點(diǎn);拓寬思路。

　　知道一點(diǎn)東西，并不能說明你會寫腳本，腳本是需要經(jīng)驗(yàn)積累的。學(xué)腳本并不難，JSP、ASP、PHP等等也不過如此--難的是長期堅(jiān)持實(shí)踐和不遺余力的博覽群書;

　　學(xué)習(xí)Java最好的方法之一就是上手動手去練習(xí);永遠(yuǎn)不要認(rèn)為自己看的書足夠了;要看懂書，仔細(xì)看書;遇到完全看不懂的書，請硬著頭皮看;別指望看第一遍書就能記住和掌握什么，一次，兩次，三次知道搞懂所有的東西;

　　不著急，因?yàn)閷W(xué)習(xí)腳本不是一蹴而就的，只有厚積才能薄發(fā)。學(xué)習(xí)的過程中，記下自己喝別人不懂的思路想法。與別人經(jīng)常交流，記錄下在別人交流時發(fā)現(xiàn)的自己忽視或不理解的知識點(diǎn);

　　首先你得學(xué)會出現(xiàn)問題自己想辦法找答案，谷歌、百度都是很好的搜索引擎，你只要輸入關(guān)鍵字就能找到很多相關(guān)資料，用自己的行動學(xué)好Java吧。

學(xué)習(xí)jsp的體會2

　　首先，你得對WEB應(yīng)用開發(fā)感興趣，因?yàn)榕d趣是最好的老師，更是你學(xué)習(xí)前進(jìn)的動力，如果只是抱這學(xué)學(xué)看的態(tài)度，本人建議不要開始學(xué)。那樣既浪費(fèi)了時間又浪費(fèi)了精力。有了興趣，一切就好說了，學(xué)得多快那就看你個人的能力了。

　　從HTML開始下手，一星期即可搞定HTML。因?yàn)殚_發(fā)WEB應(yīng)用要求你能看懂網(wǎng)頁代碼，然后是Java語言基礎(chǔ),Java語言學(xué)習(xí)的時間可能要長些。等前面這兩項(xiàng)熟悉了，就要開始學(xué)習(xí)JavaScript和CSS，當(dāng)然作為后臺程序員后面這兩項(xiàng)了解即可。

　　再接下來就要學(xué)習(xí)一下JDBC的技術(shù)了。數(shù)據(jù)庫建議先學(xué)習(xí)Mysql，然后再學(xué)習(xí)Mssql,Oracle，最后還要熟悉WEB服務(wù)器，初學(xué)者建議學(xué)習(xí)Tomcat,等這些都熟悉了。開始嘗試著開發(fā)幾個系統(tǒng)，比如信息管理系統(tǒng)，聊天室，論壇等。

　　再往后就要學(xué)習(xí)Struts,Hibernate,Spring等高級技術(shù)了。

學(xué)習(xí)jsp的體會3

　　大概的學(xué)習(xí)過程是：HTML、CSS、JavaScript、VBScript、java語言、AWT、Swing、Applet、Servlet、jsp、JDBC、MVC、Struts、Hibernate。

　　jsp程序員成長全計(jì)劃

　　1、建立并且理解你的Web Server。

　　因?yàn)锳pache 是免費(fèi)的并且在大多數(shù)平臺上工作，為訓(xùn)練目的推薦 Apache。 安裝時間：2 天。

　　2、 保證你理解 HTML / XHTML 。

　　你將需要了解html基礎(chǔ), 特別是 HTML 布局中的table的使用。XHTML 不久將代替 HTML ，學(xué)習(xí)XHTML 的基礎(chǔ)是一個好主意。許多程序員通過 HTML IDE 學(xué)習(xí)HTML ( 集成開發(fā)環(huán)境 ) 。因?yàn)榇蠖鄶?shù) HTML IDE產(chǎn)生混亂的HTMl語法，所以花時間學(xué)習(xí)手工寫作html是很有必要的。因?yàn)槟銓褂?JSP 和 HTML 混合編程，精通HTML語法是重要的。所以，你必須能流利地寫 HTML 。 訓(xùn)練時間：2 ～ 4 個星期。

　　3、開始學(xué)習(xí)Java 。

　　開始學(xué)習(xí)Java 1.4 理解 Java 基礎(chǔ)是很重要的。不用擔(dān)心學(xué)習(xí)Swing或 Java 的圖形方面，因?yàn)樵贘SP 中你不會使用這些特征。集中精力在 Java 工作的細(xì)節(jié)，學(xué)習(xí)Java 的邏輯，也在 Java Bean上花時間。學(xué)習(xí)Applet是好的, 但是就象Swing， JSP 的大多數(shù)應(yīng)用將不使用小程序。

　　訓(xùn)練時間：3 ～ 6 個星期。

　　4、學(xué)習(xí)并且理解你的Web Server的更好的細(xì)節(jié)。

　　熟悉Web Server的特征，這是很重要的。

　　訓(xùn)練時間：2 天。

　　5、建立你的 JSP Server

　　我推薦以Tomcat開始。它可以很好地運(yùn)行JSP程序。當(dāng)你不能在生產(chǎn)使用Tomcat時，學(xué)習(xí)盡可能多的知識以便于更好的運(yùn)行程序。另外, 許多 JSP 程序員使用Tomcat。因此當(dāng)你遇到一個問題時，你將容易發(fā)現(xiàn)幫助。

　　安裝時間：一～ 2 天。

　　6、開始學(xué)習(xí)JSP 。

　　基本的 JSP 學(xué)習(xí)通過的步驟 1到步驟6可以完成, 然后使用 JSP 對象和腳本寫 JSP 程序來聯(lián)系。學(xué)習(xí)JSP 的另外一個方面可以學(xué)習(xí)怎么創(chuàng)建一個分布式的應(yīng)用程序。

　　訓(xùn)練時間：4 ～ 6 個星期。

　　7、學(xué)習(xí)更多的 JSP server。

　　沒有關(guān)于更多的 JSP Server當(dāng)然也可以運(yùn)行jsp程序。然而, 許多 JSP server都由自己特殊的特征，可以讓你更好的理解你的JSP 工程。

　　學(xué)習(xí)更多的Jsp server如何處理jsp程序是有必要的。同樣也可以優(yōu)化你的 JSP 應(yīng)用程序，并且使之運(yùn)行得更快而不出任何問題。

　　訓(xùn)練時間：2 ～ 7 天。

　　8、 學(xué)習(xí)JDBC 。

　　jSP 大多數(shù)應(yīng)用將使用數(shù)據(jù)庫，JDBC 被用于數(shù)據(jù)庫連接。經(jīng)常忽略的一個事實(shí)就是，每個 JDBC Driver 所支持的東西是相當(dāng)不同的。了解并熟悉在jsp工程上被使用的 JDBC driver的細(xì)節(jié)是很重要的。

(有時這部分的學(xué)習(xí)被包含在前面 Java 或JSP的學(xué)習(xí)中了 。) 訓(xùn)練時間：1～ 2 個星期。

　　到現(xiàn)在，你已經(jīng)成為了熟練的 JSP 程序員。仍然有很多需要學(xué)習(xí)，你可以考慮擴(kuò)展你的知識比如 DHTML ， XML ，java證書， JSP Tag Libraries 或 Servlets , 看你想要造什么類型的網(wǎng)站而決定了。

學(xué)習(xí)jsp的體會4

　　任務(wù)0：了解什么是JavaScript

　　在你真正開始學(xué)習(xí)JavaScript 之前，花一分鐘了解一下什么是JavaScript，它有哪些功能。 JavaScript不是jQuery、Flash或Java。與它們不同，它是一種獨(dú)立的編程語言。 JavaScript 是瀏覽器語言(盡管現(xiàn)在不完全是)。主要目的是給靜態(tài)頁面增加交互性。在瀏覽器里，它不會為你更換PHP或Ruby，也不會更改你的HTML或CSS;你可以把它們串在一起使用。另外，它沒有你想的那么難學(xué)。 補(bǔ)充說明：你應(yīng)該聽過jQuery，它可能是被使用最廣泛的JavaScript 庫。也許你還聽說過其他比較流行的JavaScript 框架，比如Mootools,，YUI，Dojo 等等?？梢詫⑺鼈兘y(tǒng)一看做JavaScript輔助工具集;當(dāng)你使用它們的時候，你還在寫JavaScript，但都是些很抽象的JavaScript。它會讓你事半功倍。 “你甚至可能聽到有人說，你應(yīng)該先學(xué)jQuery(或其他庫)再學(xué)JavaScript。我很尊重他們但完全不同意這種說法。先把JavaScript 學(xué)好再用其他庫，你會發(fā)現(xiàn)你會做的更好;結(jié)果就是，你會編寫更好的JavaScript。”

　　任務(wù)1：通過站點(diǎn)的課程來學(xué)習(xí)

　　Codecademy是一個相對較新的網(wǎng)站，其廣告語是“最易學(xué)的編碼方法”。目前，該網(wǎng)站僅有兩個課程，“初級編程”和“JavaScript快速入門指南”。沉浸在JavaScript 中是種不錯的體驗(yàn)。跟 Try Ruby 練習(xí)非常相似，你會學(xué)到簡短的課程、在瀏覽器里編碼，然后看結(jié)果。得到全部分?jǐn)?shù)、打開成就徽章。(Ruby，一種為簡單快捷的面向?qū)ο缶幊?面向?qū)ο蟪绦蛟O(shè)計(jì))而創(chuàng)的腳本語言。) 如果你已熟悉了另一種編程語言，你也許可以先學(xué)“JavaScript快速入門指南”;如果這是您第一次編程(HTML和CSS除外)，你會發(fā)現(xiàn)“初級編程”課程相當(dāng)有用。Codecademy是一家免費(fèi)網(wǎng)站，但需要注冊。

　　任務(wù)2：appendTo 截屏方法

　　appendTo 視頻有一套特別適合初學(xué)者的截屏方法。 如果你想用正確(容易)的方法學(xué)習(xí)JavaScript，學(xué)習(xí)這些課程絕對管用。視覺訓(xùn)練總是有效的! “用我們提供的點(diǎn)播內(nèi)容、務(wù)實(shí)的訓(xùn)練解決方案來提升自己的技能。無需注冊、無需綁定、絕不忽悠?！?/p>

　　任務(wù)3：閱讀一本好的關(guān)于JavaScript 的說明書

　　一旦你通過Codecademy上的課程來學(xué)習(xí)，你就會想搞到一本關(guān)于JavaScript的詳細(xì)說明書–介紹所有的類型、運(yùn)算符、控件架構(gòu)等等。 如果可以的話，我來介紹幾個好的說明書： 《再說JavaScript》 – 這本說明書可在Mozilla開發(fā)者網(wǎng)絡(luò)上找到，語言公正。這本書內(nèi)容很豐富，有很多代碼實(shí)例和文段介紹。 《Eloquent JavaScript》 – 該書由Marijn Haverbeke 編寫，可免費(fèi)在線閱讀，如果你想弄個硬拷貝可以上亞馬遜網(wǎng)站購買。它比MDN說明更詳細(xì)，因?yàn)樗粌H涵蓋了JavaScript 語言，而且包括編碼風(fēng)格以及在瀏覽器里使用JavaScript。當(dāng)然，“eloquent”并非言過其實(shí)。(eloquent - 雄辯的、口若懸河的) 《Getting Good with JavaScript》 – 沒錯，這本書是我寫的，但是我介紹這本書是另有原因的。它跟我在前面介紹的兩本說明不同;在這本書里我只介紹了編程人員快速掌握編程技巧所需要的部分。此外，它還附帶超過6個小時的截屏視頻，因此，想要就去看看吧。(當(dāng)然，這本不是免費(fèi)的。)

　　任務(wù)4：安裝、學(xué)習(xí)Firebug(或開發(fā)人員工具)

　　一旦你開始在瀏覽器里使用JavaScript，就需要安裝Firebug并熟悉它的性能。Firebug是一款用于Firefox的插件，它能幫你創(chuàng)建和調(diào)試網(wǎng)頁：對網(wǎng)頁開發(fā)者來說，它就像外科醫(yī)生的‘手術(shù)刀'。如果你不用Firefox?喜歡Safari 或者Chrome怎么辦?沒問題：可以查找類似Firebug的內(nèi)置開發(fā)人員工具。 “你可以在Mac地址欄里按選項(xiàng)+命令+I 或者按快捷鍵Control + Shift + I ，來打開設(shè)計(jì)工具面板。” 通過打開你選的工具，只需在你喜歡的其中一個網(wǎng)站上點(diǎn)擊點(diǎn)擊，你就會學(xué)到很多東西。這里有一些能加速你學(xué)習(xí)的資源：FirebugFirebug網(wǎng)站和維基百科Firebug的CSS-技巧說明你應(yīng)該在Nettuts+上使用Firebug的10大理由。Firebug：從白帶到黑帶，Tuts+ Marketplace 設(shè)計(jì)工具設(shè)計(jì)工具網(wǎng)站Google I/O ：由Paul Irish重組的瀏覽器設(shè)計(jì)工具Google 瀏覽器設(shè)計(jì)工具：Paul Irish 的快速開發(fā)12技巧

　　任務(wù)5：讀一本有關(guān)JavaScript的書籍

　　現(xiàn)在你已經(jīng)熟悉了些基礎(chǔ)知識，但是還有很多東西要學(xué)。盡管我推薦的一些書可能會讓你‘破產(chǎn)'，但你會發(fā)現(xiàn)任何時候我都會推薦4本高質(zhì)量的書：

　　前兩本是一般的、較深入的JavaScript 資源，它們會讓你從簡介到較深層次逐步理解;當(dāng)然，簡介里會有一些重疊的說明，但不多：剛好讓你看起來很舒服。(注：雖然這些書在亞馬遜網(wǎng)站能買到，我已經(jīng)鏈接了出版商的網(wǎng)站，因此，你能看看范例章節(jié)。) 《JavaScript高級程序設(shè)計(jì)》- Nicolas C. Zakas 編寫，這本書涵蓋了它能涵蓋的所有內(nèi)容。如果你以前看過Zakas的任何作品，你會發(fā)現(xiàn)他是個不折不扣的天才。除了涵蓋了JavaScript語言，這本書還能讓您在瀏覽器里很好的使用JavaScript。 《JavaScript 24-hour Trainer 》由Jeremy McPeak 編撰，該作者也寫過Nettuts+。它不僅僅是一本書：還附帶了一張長達(dá)四小時的教學(xué)光碟。全書共43節(jié)課，涉及編碼句法指導(dǎo)和代碼優(yōu)化。 雖然這些書非常適合編程人員學(xué)習(xí)JavaScript語言以及如何在瀏覽器中使用這些語言，但是學(xué)無止境。雖然這些書的確進(jìn)入了一些模式和實(shí)練中，我再推薦兩本我認(rèn)為有用的書。1)《JavaScript Patterns 》- Stoyan Stefanov著。我也是剛剛讀完這本書，我真希望能盡快讀完它。在讀過上面的資源之后，你可以學(xué)到如何編寫JavaScript，但是這本書會教你如何對資源進(jìn)行重組，這項(xiàng)技能很重要，并非如你想象般簡單。2)《JavaScript：The Good Parts 》- Douglas Crockford 著。該書介紹了JavaScript的優(yōu)缺點(diǎn)。

學(xué)習(xí)jsp的體會5

　　1.首先要有Java語言基礎(chǔ);也就是先要掌握J(rèn)ava SE的知識，不會Java，談何JSP呢?

　　2. 掌握一種數(shù)據(jù)庫開發(fā)，Oracle/DB2/SQL Server/MySQL等等;不要求你會多強(qiáng)的DBA管理能力，你必須會標(biāo)準(zhǔn)SQL的編寫，同時結(jié)合具體數(shù)據(jù)庫，掌握這個數(shù)據(jù)庫的特殊SQL命令、存儲過程，同時學(xué)會JDBC。大多數(shù)企業(yè)級Web應(yīng)用開發(fā)離不開和數(shù)據(jù)庫打交道。

　　3.掌握Tomcat的搭建;目前為止，只要求一般性的知識，能讓你的學(xué)習(xí)例子運(yùn)行起來即可。

　　4.掌握HTML知識，至少了解JavaScript、CSS、XML;這些都是JSP周邊知識，特別是HTML，聯(lián)系最是緊密。若要掌握現(xiàn)今流行的AJAX，JavaScript等知識更是要下工夫了。

　　5. 學(xué)習(xí)JSP;對于學(xué)習(xí)Java、J2EE、具體到學(xué)習(xí)JSP方面的入門書籍，我覺得合我習(xí)慣的有很多，但我不太敢推薦，因?yàn)楹线m我的，不一定合適別人，怕誤導(dǎo)初學(xué)者，但是有一本書，我是非常有信心推薦給初學(xué)者，那就是《Servlet與JSP核心編程(第2版)》(《Core Servlets and JavaServer Pages:Volume 1:Core Technologies, 2nd Edition》，有中文版的)，很好的一本書!這本書很重要的一點(diǎn)是教會初學(xué)者一些方法，缺點(diǎn)是講解JSP 2.0的東西比較少，顯得內(nèi)容不太新，但從某個角度來說，對于初學(xué)者打下較好JSP基礎(chǔ)也未嘗沒有好處，畢竟現(xiàn)在很多代碼還不是基于JSP 2.0;注意一點(diǎn)，無論你覺得這本書有多好，記住它只是適合初學(xué)者，很多內(nèi)容它沒有涵蓋或擴(kuò)展。學(xué)習(xí)JSP，強(qiáng)調(diào)一點(diǎn)，別輕視Servlet的重要性!

　　6. 當(dāng)然，結(jié)合實(shí)踐來學(xué)習(xí)、勤動手，是毋需多言的。學(xué)習(xí)過程會遇到形形色色的問題，這也是為什么要結(jié)合實(shí)踐的的原因，只有實(shí)作，才會遇到更多問題，才給你提供了強(qiáng)化知識理解、豐富技術(shù)經(jīng)驗(yàn)的機(jī)會。碰到問題，我覺得解決流程的優(yōu)先順序應(yīng)該是：思考->查資料(充分利用搜索引擎的作用)->提問題，不應(yīng)該一有問題，馬上就到論壇發(fā)問，這樣效果非常不好。在問題解決以后，要善于總結(jié)。

　　7.提升自己的技能;你一旦熟悉了JSP的開發(fā)，不應(yīng)該只是滿足于現(xiàn)狀，應(yīng)該繼續(xù)學(xué)習(xí)對你有幫助的相關(guān)知識，如Framework;成熟的Framework很多，而且都有眾多擁躉，看你的實(shí)際來選擇吧，但是選擇過程一定會讓你眼花繚亂，因?yàn)镕ramework實(shí)在太多了，呵呵，這也說明了Java的流行度。

　　8.如果要涉足企業(yè)級開發(fā)，你還差一步，就是掌握至少一種Java Web應(yīng)用服務(wù)器的操作，包括部署以及一些管理操作。

　　jsp文件怎么打開

　　jsp文件一般用記事本就能打開。

　　jSP(Java Server Pages)是由Sun Microsystems公司倡導(dǎo)、許多公司參與一起建立的一種動態(tài)網(wǎng)頁技術(shù)標(biāo)準(zhǔn)。 JSP技術(shù)是用JAVA語言作為腳本語言的，JSP網(wǎng)頁為整個服務(wù)器端的JAVA庫單元提供了一個接口來服務(wù)于HTTP的應(yīng)用程序。

　　在傳統(tǒng)的網(wǎng)頁HTML文件(htm,html)中加入Java程序片段(Scriptlet)和JSP標(biāo)記(tag)，就構(gòu)成了JSP網(wǎng)頁(jsp)。Web服務(wù)器在遇到訪問JSP網(wǎng)頁的請求時，首先執(zhí)行其中的程序片段，然后將執(zhí)行結(jié)果以HTML格式返回給客戶。程序片段可以操作數(shù)據(jù)庫、重新定向網(wǎng)頁以及發(fā)送email 等等，這就是建立動態(tài)網(wǎng)站所需要的功能。

　　所有程序操作都在服務(wù)器端執(zhí)行，網(wǎng)絡(luò)上傳送給客戶端的僅是得到的結(jié)果，對客戶瀏覽器的要求最低，可以實(shí)現(xiàn)無Plugin，無ActiveX，無Java Applet，甚至無Frame。

學(xué)習(xí)jsp的體會8

　　1.不要讓未來的決策阻止你現(xiàn)在前進(jìn)的方向

　　很多人學(xué)習(xí)JavaScript，問的第一個問題往往是“我應(yīng)該使用哪個框架?”。但是，如果你還沒有掌握最最基礎(chǔ)的JavaScript，那這顯然是一個錯誤的問題。你將你所有的時間用來研究不同的框架，于是，你開始停滯不前。

　　幫助擺脫這種陷阱的方法之一是畫一個你需要學(xué)習(xí)的路線圖。例如，要想成為一個前端開發(fā)者，你的路線圖可能是這樣的：

　　進(jìn)一步分解的話，你可以做一個只有HTML和CSS的功能性web頁面。然后像這樣一步步列出每個步驟，那么對于現(xiàn)在應(yīng)該專注于做什么，就一目了然了。你也不會浪費(fèi)時間去擔(dān)心應(yīng)該以后操心的事情。

　　2.不要讓自信誘騙你忘事

　　快速了解一個概念，也許是學(xué)習(xí)JavaScript的道路上最影響你進(jìn)步的事情之一。下面請?jiān)试S我解釋一下。

　　當(dāng)你讀到某些東西，你覺得的確如此的，那么很可能就會直接跳到下一個內(nèi)容。然后你覺得接下來這個內(nèi)容也非常淺顯易懂，于是繼續(xù)往下看。但很快，你會 發(fā)現(xiàn)你已經(jīng)忘記了前面自認(rèn)為已經(jīng)掌握的內(nèi)容，所以只能回過頭去溫習(xí)。你快速地瀏覽了一遍，感覺又明白了，然后繼續(xù)前進(jìn)。但是你又發(fā)現(xiàn)自己忘記了別的東西。 你一直處在這個循環(huán)中，直到最終迷失了自己。你不由地氣餒，想著那先休息一下吧，然而當(dāng)你休息完了再回來的時候，你發(fā)現(xiàn)你已經(jīng)忘記了所有的內(nèi)容。

　　解決這個問題，也很簡單，只需要兩步：

　　限制一次學(xué)習(xí)的量。

　　實(shí)踐——實(shí)際編寫代碼。

　　當(dāng)你去學(xué)習(xí)一個新概念的時候，一定要試用它，擺弄它，熟悉它，甚至將它和其他概念結(jié)合起來。而且實(shí)際輸出到示例代碼中非常重要，因?yàn)檫@能幫助你消化吸收它。此外，限制一次學(xué)習(xí)的量，有助于記住資料，道理也很簡單，東西越少越好記。

　　雖然這種學(xué)習(xí)進(jìn)程會讓你感覺所需的時間更多，但實(shí)際上恰恰相反，因?yàn)槟悴辉傩枰吣敲炊嗟幕仡^路。我也是經(jīng)過了很多次慘不忍睹的教訓(xùn)才明白了這個技巧。

　　3.用正確的心態(tài)去做練習(xí)

　　很多人認(rèn)為反復(fù)的練習(xí)特別無聊，所以他們通常會選擇跳過或嘗試走捷徑。如果你快進(jìn)JavaScript練習(xí)，那么最終反而需要更多的學(xué)習(xí)時間。試著讓練習(xí)變得令人感興趣，這樣是不是就不會那么抗拒呢?

　　試著轉(zhuǎn)變心態(tài)：

　　如果讓你學(xué)習(xí)一個新的JavaScript概念，卻不能試試，會怎么樣?你是什么感覺?從我個人而言，我會特別懊惱。這就像一個孩子得到一個新的玩具，卻不能玩一樣。

　　當(dāng)你學(xué)習(xí)JavaScript中一些新內(nèi)容的時候，試著將它當(dāng)作新玩具，新車，新鞋，或者其他任何你有興趣嘗試的東西。然后不要將練習(xí)當(dāng)作工作，要將練習(xí)當(dāng)作是玩耍。用新技能去嘗試一些很酷的東西。讓你自己都不由的驚嘆。然后顯擺給你的朋友看。

　　用一種游戲的心態(tài)，你會學(xué)得更快，記得更久，擁有更多的樂趣。

　　4.寫代碼的時間魔法

　　在學(xué)習(xí)JavaScript中最常見的問題是，找不到時間寫代碼。但是，與此同時，卻有大把大把的時間瀏覽各種網(wǎng)站，如Facebook，YouTube，維基百科和Reddit等。

　　我有好幾次，一開始只是想打開Facebook，看一小會，然后不知不覺就發(fā)現(xiàn)已經(jīng)看了幾個小時。這是怎么發(fā)生的呢?或許正是因?yàn)槲也⒉淮蛩憧春荛L 時間。萬事開頭難，一旦開了頭，后面陷進(jìn)去就變得容易多了。但是如果有人問我，是否愿意花時間在Facebook上，我會堅(jiān)決地說不，因?yàn)槲冶旧頃r間就不 夠用。然而，只允許看一會會時間往往更容易接受，然后深陷其中。

　　好消息是，你也可以利用同樣的心理來學(xué)習(xí)寫代碼。一開始不要想著要編碼幾小時，因?yàn)槟阌肋h(yuǎn)找不到這么多的時間。就告訴自己你要去寫3分鐘的代碼。這樣你永遠(yuǎn)也不用愁擠不出時間了。

　　5.思考得更慢，學(xué)得更快

　　這聽起來貌似有悖常理，下面我會用一個小故事解釋。

　　我的一個朋友曾經(jīng)對JavaScript的某個功能感到困惑。于是，我讓他詳細(xì)地說一遍哪些是他知道的，然后給他解釋他感到困惑的那部分。不過，當(dāng)他檢查代碼片段的時候，我注意到有一段代碼，他說得非常倉促。

“等一下!”我說， “慢點(diǎn)講，每一步都詳細(xì)地說一下?！?/p>

　　我的朋友繼續(xù)給我做代碼發(fā)生了什么的全面總結(jié)。

　　我只好再次叫住他。 “你還是太倉促了。再試一次，但這次，我希望你能從字面上去檢查每一行代碼，告訴每一行的代碼都發(fā)生了什么?！?/p>

　　這次，我的朋友終于能夠很好地解釋代碼中正在發(fā)生什么。問題的關(guān)鍵是，他終于可以一步一步地檢查了代碼片段，而不是囫圇吞棗想要一次性理解所有代碼。

　　在類似于這樣的情況下，思考得更慢實(shí)際上能讓你學(xué)得更快。

學(xué)習(xí)jsp的體會9

　　首先要定義四個變量：

　　Int pageSize:每頁顯示多少條記錄

　　Int pageNow:希望顯示第幾頁

　　Int pageCount:一共有多少頁

　　Int rowCount:一共有多少條記錄

　　說明：

　　pageSize是指定的 pageNow是用戶選擇的

　　rowCount是計(jì)算出來的 該計(jì)算式為

　　If(rowCount%pageSize==0){

　　pageCount=rowCount/pageSize;

}else{

　　pageCount=rowCount/pageSize+1;

}

(技巧：

　　數(shù)據(jù)庫插入：

　　Insert into 表名(字段1，2，，。。)select 字段1,2,...from 表名

)

　　查詢語句

　　Select top pageSize字段名列表from表名where id not in

(select top pageSize*(pageNow-1)id from 表名)

　　以我們前面的users表為例，顯示第二頁，該查詢語句就是：

　　Select top 3 * from users where userId not in(select top 3 userId from users)

(select top 3 userId from users):選出這個表的前三條 前面再選三條

用戶信息列表

<%

//定義四個分頁會用到的變量

　　Int pageSize=3;

　　Int pageNow=1;//默認(rèn)顯示第一頁

　　Int rowCount=0;//該值從數(shù)據(jù)庫中查詢

　　Int pageCount=0;//該值是通過pageSize和rowCount

//接受用戶希望顯示的頁數(shù)（pageNow）

　　String s_pageNow=request.getParameter(“pageNow”);

　　If(s_pageNow!=null){

//接收到了pageNow

　　pageNow=Integer.parseInt(s_pageNow);

}

//查詢得到rowCount

　　Class.forName(“com.microsoft.jdbc.sqlserver.SQLServerDriver”);

　　Connection ct=DriverManager.getConnection(“jdbc:microsoft: sm=ct.createStatement;

　　resultSet rs=sm.exeuteQuery(“select count(*) form. users ”);

　　If(rs.next()){

　　rowCount=rs.getInt(1);

}

//計(jì)算pageCount

　　If(rowCount%pageSize==0){

　　pageCount=rowCount/pageSize;

}else{

　　pageCount=rowCount/pageSize+1;

}

//查詢出需要顯示的記錄

　　rs=sm.exeuteQuery(“select top ”+pageSize

+“ * from users where userId not in(select top ”

+pageSize*(pageNow-1)+“ userId from users) ”);

%>

//顯示

　　用戶ID用戶名字密碼電郵級別

<%

　　while(rs.next()){

%>

<%

//上一頁

　　If(pageNow!=1){

　　out.println(“上一頁”);

}

//顯示超鏈接

　　for(int i=1;i<=pageCount;i++){

　　out.println(“[”+i+“]”);

}

//下一頁

　　If(pageNow!=pageCount){

　　out.println(“下一頁”);

}

%>

學(xué)習(xí)jsp的體會10

　　1. 多實(shí)踐,快實(shí)踐

　　軟件開發(fā)是一門工程學(xué)科，注重的就是實(shí)踐，“君子動口不動手“對軟件開發(fā)人員來講根本就是錯誤的，他們提倡”動手至上”，但別害怕，他們大多溫文爾雅，沒有暴力傾向，雖然有時候蓬頭垢面的一副“比爾蓋茨”樣。有前輩高人認(rèn)為，學(xué)習(xí)編程的秘訣是：編程、編程、再編程，筆者深表贊同。不僅要多實(shí)踐，而且要快實(shí)踐。我們在看書的時候，不要等到你完全理解了才動手敲代碼，而是應(yīng)該在看書的同時敲代碼，程序運(yùn)行的各種情況可以讓你更快更牢固的掌握知識點(diǎn)。

　　2. 多參考程序代碼

　　程序代碼是軟件開發(fā)最重要的成果之一，其中滲透了程序員的思想與靈魂。許多人被《仙劍奇?zhèn)b傳》中凄美的愛情故事感動,悲劇的結(jié)局更有一種缺憾美。為什么要以悲劇結(jié)尾?據(jù)說是因?yàn)閷憽断蓜ζ鎮(zhèn)b傳》的程序員失戀而安排了這樣的結(jié)局，他把自己的感覺融入到游戲中，卻讓眾多的仙劍迷扼腕嘆息。

　　3.加強(qiáng)英文閱讀能力

　　對學(xué)習(xí)編程來說，不要求英語,但不能一點(diǎn)不會,。最起碼像JAVAAPI文檔(參考文獻(xiàn)[4.4])這些東西還是要能看懂的,連猜帶懵都可以;旁邊再開啟一個“金山詞霸”?？炊嗔司蜁絹碓绞炀?。在學(xué)JAVA的同時學(xué)習(xí)英文，一箭雙雕多好。另外好多軟件需要到英文網(wǎng)站下載，你要能夠找到它們，這些是最基本的要求。英語好對你學(xué)習(xí)有很大的幫助?？谡Z好的話更有機(jī)會進(jìn)入管理層，進(jìn)而可以成為剝削程序員的“周扒皮”。

　　3. 萬不得已才請教別人

　　筆者在ChinaITLab網(wǎng)校的在線輔導(dǎo)系統(tǒng)中解決學(xué)生問題時發(fā)現(xiàn)，大部分的問題學(xué)生稍做思考就可以解決。請教別人之前，你應(yīng)該先回答如下幾個問題。 你是否在google中搜索了問題的解決辦法? 你是否查看了JAVAAPI文檔? 你是否查找過相關(guān)書籍? 你是否寫代碼測試過? 如果回答都是“是”的話，而且還沒有找到解決辦法，再問別人不遲。要知道獨(dú)立思考的能力對你很重要。要知道程序員的時間是很寶貴的。

　　4.多讀好書

　　書中自有顏如玉。比爾?蓋茨是一個飽讀群書的人。雖然沒有讀完大學(xué)，但九歲的時候比爾?蓋茨就已經(jīng)讀完了所有的百科全書，所以他精通天文、歷史、地理等等各類學(xué)科，可以說比爾?蓋茨不僅是當(dāng)今世界上金錢的首富，而且也可以稱得上是知識的巨富。

　　1、在金融業(yè)應(yīng)用的服務(wù)器程序Java在金融服務(wù)業(yè)的應(yīng)用非常廣泛，很多第三方交易系統(tǒng)、銀行、金融機(jī)構(gòu)都選擇用Java開發(fā)，因?yàn)橄鄬Χ?，Java較安全 。大型跨國投資銀行用Java來編寫前臺和后臺的電子交易系統(tǒng)，結(jié)算和確認(rèn)系統(tǒng)，數(shù)據(jù)處理項(xiàng)目以及其他項(xiàng)目。大多數(shù)情況下，Java被用在服務(wù)器端開發(fā)，但多數(shù)沒有任何前端，它們通常是從一個服務(wù)器(上一級)接收數(shù)據(jù)，處理后發(fā)向另一個處理系統(tǒng)(下一級處理)。

　　2、Android應(yīng)用許多的 Android應(yīng)用都是Java程序員開發(fā)者開發(fā)。雖然 Android運(yùn)用了不同的JVM以及不同的封裝方式，但是代碼還是用Java語言所編寫。相當(dāng)一部分的手機(jī)中都支持JAVA游戲，這就使很多非編程人員都認(rèn)識了JAVA。

　　3、網(wǎng)站Java 在電子商務(wù)領(lǐng)域以及網(wǎng)站開發(fā)領(lǐng)域占據(jù)了一定的席位。開發(fā)人員可以運(yùn)用許多不同的框架來創(chuàng)建web項(xiàng)目，SpringMVC，Struts2.0以及frameworks。即使是簡單的 servlet，jsp和以struts為基礎(chǔ)的網(wǎng)站在政府項(xiàng)目中也經(jīng)常被用到。例如醫(yī)療救護(hù)、保險(xiǎn)、教育、國防以及其他的不同部門網(wǎng)站都是以Java為基礎(chǔ)來開發(fā)的。

　　4、科學(xué)應(yīng)用Java在科學(xué)應(yīng)用中是很好選擇，包括自然語言處理。最主要的原因是因?yàn)镴ava比C++或者其他語言相對其安全性、便攜性、可維護(hù)性以及其他高級語言的并發(fā)性更好

　　5、嵌入式領(lǐng)域Java在嵌入式領(lǐng)域發(fā)展空間很大。在這個平臺上，只需130KB就能夠使用Java技術(shù)(在智能卡或者傳感器上)。

　　6、高頻交易的空間Java平臺提高了這個平臺的特性和即使編譯，他同時也能夠像 C++ 一樣傳遞數(shù)據(jù)。正是由于這個原因，Java成為的程序員編寫交易平臺的語言，因?yàn)殡m然性能不比C++，但開發(fā)人員可以避開安全性，可移植性和可維護(hù)性等問題。

　　7、大數(shù)據(jù)技術(shù)Hadoop以及其他大數(shù)據(jù)處理技術(shù)很多都是用Java，例如Apache的基于Java的HBase和Accumulo以及ElasticSearchas。

　　1.不要總對別人說給個代碼吧!你應(yīng)該多想想如何做，怎么做 ? 當(dāng)你自己想出來再參考別人的提示，你就知道自己和別人思路的差異，這樣才能進(jìn)步。

　　2.初學(xué)者請不要看太多太多的書，太多太多的書只會紛亂你的心思，先找本好書完整系統(tǒng)的學(xué)，很多人只對部分功能熟悉而已，不系統(tǒng)、功能體系上還是不夠的。

　　3.看幫助,不要因?yàn)楹茈y而自己是初學(xué)者所以就不看 ; 多看參考手冊，雖然你可能看不懂，總覺得不夠直觀。但這才是最根本的東西。

　　4.不要被對象、屬性、方法等詞匯所迷惑 ; 最根本的是先了解最基礎(chǔ)的知識。

　　5.要關(guān)注那些細(xì)小的細(xì)節(jié)的問題--他們往往并不那么簡單，為了解決它你可能要用到很多很多的東西，幫你回顧知識點(diǎn);拓寬思路。

　　6.知道一點(diǎn)東西，并不能說明你會寫程序，程序是需要經(jīng)驗(yàn)積累的。學(xué)程序并不難，C、JAVA、JSP、ASP、PHP等等也不過如此--難的是長期堅(jiān)持實(shí)踐和不遺余力的博覽群書 ; 永遠(yuǎn)不要認(rèn)為自己看的書足夠了 ; 要看懂書，仔細(xì)看書;遇到完全看不懂的書，請硬著頭皮看 ; 別指望看第一遍書就能記住和掌握什么，一次，兩次，三次直到搞懂所有的東西;

　　7.學(xué)習(xí)Java最好的方法之一就是動手去練習(xí):多多動手，多多練習(xí)，你才能快速提升，才能快速成長;

　　8.不著急，因?yàn)閷W(xué)習(xí)不是一蹴而就的，只有厚積才能薄發(fā);學(xué)習(xí)的過程中，記下自己和別人不懂的思路想法;與別人經(jīng)常交流，記錄下在和別人交流時發(fā)現(xiàn)的自己忽視或不理解的知識點(diǎn);

　　9.首先你得學(xué)會出現(xiàn)問題自己想辦法找答案，谷歌、百度都是很好的搜索引擎，你只要輸入關(guān)鍵字就能找到很多相關(guān)資料，用自己的行動學(xué)好Java吧。
