学习jsp的体会(共10篇)由网友“梅川神奈simon”投稿提供,下面是小编整理过的学习jsp的体会,希望对大家有所帮助。
篇1:初学者如何学习jsp
1、建立并且理解你的Web Server。
因为Apache 是免费的并且在大多数平台上工作,为训练目的推荐 Apache。
安装时间:2 天。
2、 保证你理解 HTML / XHTML 。
你将需要了解html基础, 特别是 HTML 布局中的table的使用。XHTML 不久将代替 HTML ,学习XHTML 的基础是一个好主意。许多程序员通过 HTML IDE 学习HTML ( 集成开发环境 ) 。因为大多数 HTML IDE产生混乱的HTMl语法,所以花时间学习手工写作html是很有必要的。因为你将会使用 JSP 和 HTML 混合编程,精通HTML语法是重要的。所以,你必须能流利地写 HTML 。
训练时间:2 ~ 4 个星期。
3、开始学习Java 。
开始学习Java 1.3 理解 Java 基础是很重要的。不用担心学习Swing或 Java 的图形方面,因为在JSP 中你不会使用这些特征。集中精力在 Java 工作的细节,学习Java 的逻辑,也在 Java Bean上花时间。学习Applet是好的, 但是就象Swing, JSP 的大多数应用将不使用小程序。
训练时间:3 ~ 6 个星期。
3、学习JavaScript
学习怎么将 JavaScript在HTML中验证输入的Form元素。也学习JavaScript怎么能在一 HTML 页以内修改Form的元素。最后要求你能从一
HTML 页内的事件中触发 JavaScript Function。
训练时间:一~ 2 个星期。
4、学习并且理解你的Web Server的更好的细节。
熟悉Web Server的特征,这是很重要的。
训练时间:2 天。
5、建立你的 JSP Server
我推荐以Tomcat开始。它可以很好地运行JSP程序。当你不能在生产使用Tomcat时,学习尽可能多的知识以便于更好的运行程序。另外, 许多 JSP 程序员使用Tomcat。因此当你遇到一个问题时,你将容易发现帮助。
安装时间:一~ 2 天。
6、开始学习JSP 。
基本的 JSP 学习通过的步骤 1到步骤6可以完成, 然后使用 JSP 对象和脚本写 JSP 程序来联系。学习JSP 的另外一个方面可以学习怎么创建一个分布式的应用程序。
训练时间:4 ~ 6 个星期。
7、学习更多的 JSP server。
没有关于更多的 JSP Server当然也可以运行jsp程序。然而, 许多 JSP server都由自己特殊的特征,可以让你更好的理解你的JSP 工程。学习更多的Jsp server如何处理jsp程序是有必要的。同样也可以优化你的 JSP 应用程序,并且使之运行得更快而不出任何问题。
训练时间:2 ~ 7 天。
篇2:初学者如何学习jsp
1.首先要有Java语言基础;也就是先要掌握Java SE的知识,不会Java,谈何JSP呢?
2. 掌握一种数据库开发,Oracle/DB2/SQL Server/MySQL等等;不要求你会多强的DBA管理能力,你必须会标准SQL的编写,同时结合具体数据库,掌握这个数据库的特殊SQL命令、存储过程,同时学会JDBC。大多数企业级Web应用开发离不开和数据库打交道。
3.掌握Tomcat的搭建;目前为止,只要求一般性的知识,能让你的学习例子运行起来即可。
4.掌握HTML知识,至少了解JavaScript、CSS、XML;这些都是JSP周边知识,特别是HTML,联系最是紧密。若要掌握现今流行的AJAX,JavaScript等知识更是要下工夫了。
5. 学习JSP;对于学习Java、J2EE、具体到学习JSP方面的入门书籍,我觉得合我习惯的有很多,但我不太敢推荐,因为合适我的,不一定合适别人,怕误导初学者,但是有一本书,我是非常有信心推荐给初学者,那就是《Servlet与JSP核心编程(第2版)》(《Core Servlets and JavaServer Pages:Volume 1:Core Technologies, 2nd Edition》,有中文版的),很好的一本书!这本书很重要的一点是教会初学者一些方法,缺点是讲解JSP 2.0的东西比较少,显得内容不太新,但从某个角度来说,对于初学者打下较好JSP基础也未尝没有好处,毕竟现在很多代码还不是基于JSP 2.0;注意一点,无论你觉得这本书有多好,记住它只是适合初学者,很多内容它没有涵盖或扩展。学习JSP,强调一点,别轻视Servlet的重要性!
6. 当然,结合实践来学习、勤动手,是毋需多言的。学习过程会遇到形形色色的问题,这也是为什么要结合实践的的原因,只有实作,才会遇到更多问题,才给你提供了强化知识理解、丰富技术经验的机会。碰到问题,我觉得解决流程的优先顺序应该是:思考->查资料(充分利用搜索引擎的作用)->提问题,不应该一有问题,马上就到论坛发问,这样效果非常不好。在问题解决以后,要善于总结。
7.提升自己的技能;你一旦熟悉了JSP的开发,不应该只是满足于现状,应该继续学习对你有帮助的相关知识,如Framework;成熟的Framework很多,而且都有众多拥趸,看你的实际来选择吧,但是选择过程一定会让你眼花缭乱,因为Framework实在太多了,呵呵,这也说明了Java的流行度。
8.如果要涉足企业级开发,你还差一步,就是掌握至少一种Java Web应用服务器的操作,包括部署以及一些管理操作。
篇3:初学者如何学习jsp
首先,你得对WEB应用开发感兴趣,因为兴趣是最好的老师,更是你学习前进的动力,如果只是抱这学学看的态度,本人建议不要开始学。那样既浪费了时间又浪费了精力。有了兴趣,一切就好说了,学得多快那就看你个人的能力了。
从HTML开始下手,一星期即可搞定HTML。因为开发WEB应用要求你能看懂网页代码,然后是Java语言基础,Java语言学习的时间可能要长些。等前面这两项熟悉了,就要开始学习JavaScript和CSS,当然作为后台程序员后面这两项了解即可。
再接下来就要学习一下JDBC的技术了。数据库建议先学习Mysql,然后再学习Mssql,Oracle,最后还要熟悉WEB服务器,初学者建议学习Tomcat,等这些都熟悉了。开始尝试着开发几个系统,比如信息管理系统,聊天室,论坛等。
再往后就要学习Struts,Hibernate,Spring等高级技术了。
篇4:JSP学习计划
大概的学习过程是:HTML、CSS、JavaScript、VBScript、java语言、AWT、Swing、Applet、Servlet、jsp、JDBC、MVC、Struts、Hibernate。
jsp程序员成长全计划

8、 学习JDBC 。
JSP 大多数应用将使用数据库,JDBC 被用于数据库连接。经常忽略的一个事实就是,每个 JDBC Driver 所支持的东西是相当不同的。了解并熟悉在jsp工程上被使用的 JDBC driver的细节是很重要的。
(有时这部分的学习被包含在前面 Java 或JSP的学习中了 。) 训练时间:1~ 2 个星期。
到现在,你已经成为了熟练的 JSP 程序员。仍然有很多需要学习,你可以考虑扩展你的知识比如 DHTML , XML ,java证书, JSP Tag Libraries 或 Servlets , 看你想要造什么类型的网站而决定了。

jsp文件怎么打开
jsp文件一般用记事本就能打开。
JSP(Java Server Pages)是由Sun Microsystems公司倡导、许多公司参与一起建立的一种动态网页技术标准。 JSP技术是用JAVA语言作为脚本语言的,JSP网页为整个服务器端的JAVA库单元提供了一个接口来服务于HTTP的应用程序。
在传统的网页HTML文件(htm,html)中加入Java程序片段(Scriptlet)和JSP标记(tag),就构成了JSP网页(jsp)。Web服务器在遇到访问JSP网页的请求时,首先执行其中的程序片段,然后将执行结果以HTML格式返回给客户。程序片段可以操作数据库、重新定向网页以及发送email 等等,这就是建立动态网站所需要的功能。
所有程序操作都在服务器端执行,网络上传送给客户端的仅是得到的结果,对客户浏览器的要求最低,可以实现无Plugin,无ActiveX,无Java Applet,甚至无Frame。
篇6:JSP中分页方法学习
首先要定义四个变量:
int pageSize:每页显示多少条记录
int pageNow:希望显示第几页
int pageCount:一共有多少页
int rowCount:一共有多少条记录
说明:
pageSize是指定的 pageNow是用户选择的
rowCount是计算出来的 该计算式为
if(rowCount%pageSize==0){
pageCount=rowCount/pageSize;
}else{
pageCount=rowCount/pageSize+1;
}
(技巧:
数据库插入:
insert into 表名(字段1,2,,。。)select 字段1,2,...from 表名
)
查询语句
select top pageSize字段名列表from表名where id not in
(select top pageSize*(pageNow-1)id from 表名)
以我们前面的users表为例,显示第二页,该查询语句就是:
select top 3 * from users where userId not in(select top 3 userId from users)
(select top 3 userId from users):选出这个表的前三条 前面再选三条
用户信息列表
<%
//定义四个分页会用到的变量
int pageSize=3;
int pageNow=1;//默认显示第一页
int rowCount=0;//该值从数据库中查询
int pageCount=0;//该值是通过pageSize和rowCount
//接受用户希望显示的页数(pageNow)
String s_pageNow=request.getParameter(“pageNow”);
if(s_pageNow!=null){
//接收到了pageNow
pageNow=Integer.parseInt(s_pageNow);
}
//查询得到rowCount
Class.forName(“com.microsoft.jdbc.sqlserver.SQLServerDriver”);
Connection ct=DriverManager.getConnection(“jdbc:microsoft:sqlserver://127.0.0.1:1433;dataBaseName=System”,“sa”,“”);
Statement sm=ct.createStatement;
ResultSet rs=sm.exeuteQuery(“select count(*) form. users ”);
if(rs.next()){
rowCount=rs.getInt(1);
}
//计算pageCount
if(rowCount%pageSize==0){
pageCount=rowCount/pageSize;
}else{
pageCount=rowCount/pageSize+1;
}
//查询出需要显示的记录
rs=sm.exeuteQuery(“select top ”+pageSize
+“ * from users where userId not in(select top ”
+pageSize*(pageNow-1)+“ userId from users) ”);
%>
//显示
用户ID用户名字密码电邮级别
<%
while(rs.next()){
%>
<%=rs.getInt(1)%><%=rs.getString(2)%>
<%=rs.getString(3)%><%=rs.getString(4)%><%=rs.getInt(5)%>
<%}%>
<%
//上一页
if(pageNow!=1){
out.println(“上一页”);
}
//显示超链接
for(int i=1;i<=pageCount;i++){
out.println(“[”+i+“]”);
}
//下一页
if(pageNow!=pageCount){
out.println(“下一页”);
}
%>
篇7:手工注射JSP学习脚本安全
1、 判断注入类型(数字型还是字符型)
字符型和数字型数据判断:(希望有人能进一步的细化,细分为数字型和字符型判断两部分)

篇8:如何才能正确的学习jsp编程
正确的学习jsp编程的方法
1. 多实践,快实践
软件开发是一门工程学科,注重的就是实践,“君子动口不动手“对软件开发人员来讲根本就是错误的,他们提倡”动手至上”,但别害怕,他们大多温文尔雅,没有暴力倾向,虽然有时候蓬头垢面的一副“比尔盖茨”样。有前辈高人认为,学习编程的秘诀是:编程、编程、再编程,笔者深表赞同。不仅要多实践,而且要快实践。我们在看书的时候,不要等到你完全理解了才动手敲代码,而是应该在看书的同时敲代码,程序运行的各种情况可以让你更快更牢固的掌握知识点。
2. 多参考程序代码
程序代码是软件开发最重要的成果之一,其中渗透了程序员的思想与灵魂。许多人被《仙剑奇侠传》中凄美的爱情故事感动,悲剧的结局更有一种缺憾美。为什么要以悲剧结尾?据说是因为写《仙剑奇侠传》的程序员失恋而安排了这样的结局,他把自己的感觉融入到游戏中,却让众多的仙剑迷扼腕叹息。
3.加强英文阅读能力
对学习编程来说,不要求英语,但不能一点不会,。最起码像JAVAAPI文档(参考文献[4.4])这些东西还是要能看懂的,连猜带懵都可以;旁边再开启一个“金山词霸”。看多了就会越来越熟练。在学JAVA的同时学习英文,一箭双雕多好。另外好多软件需要到英文网站下载,你要能够找到它们,这些是最基本的要求。英语好对你学习有很大的帮助。口语好的话更有机会进入管理层,进而可以成为剥削程序员的“周扒皮”。
3. 万不得已才请教别人
笔者在ChinaITLab网校的在线辅导系统中解决学生问题时发现,大部分的问题学生稍做思考就可以解决。请教别人之前,你应该先回答如下几个问题。 你是否在google中搜索了问题的解决办法? 你是否查看了JAVAAPI文档? 你是否查找过相关书籍? 你是否写代码测试过? 如果回答都是“是”的话,而且还没有找到解决办法,再问别人不迟。要知道独立思考的能力对你很重要。要知道程序员的时间是很宝贵的。
4.多读好书
书中自有颜如玉。比尔?盖茨是一个饱读群书的人。虽然没有读完大学,但九岁的时候比尔?盖茨就已经读完了所有的百科全书,所以他精通天文、历史、地理等等各类学科,可以说比尔?盖茨不仅是当今世界上金钱的首富,而且也可以称得上是知识的巨富。
正确的学习jsp编程的注意事项
1.不要总对别人说给个代码吧!你应该多想想如何做,怎么做 ? 当你自己想出来再参考别人的提示,你就知道自己和别人思路的差异,这样才能进步。
2.初学者请不要看太多太多的书,太多太多的书只会纷乱你的心思,先找本好书完整系统的学,很多人只对部分功能熟悉而已,不系统、功能体系上还是不够的。
3.看帮助,不要因为很难而自己是初学者所以就不看 ; 多看参考手册,虽然你可能看不懂,总觉得不够直观。但这才是最根本的东西。
4.不要被对象、属性、方法等词汇所迷惑 ; 最根本的是先了解最基础的知识。
5.要关注那些细小的细节的问题--他们往往并不那么简单,为了解决它你可能要用到很多很多的东西,帮你回顾知识点;拓宽思路。
6.知道一点东西,并不能说明你会写程序,程序是需要经验积累的。学程序并不难,C、JAVA、JSP、ASP、PHP等等也不过如此--难的是长期坚持实践和不遗余力的博览群书 ; 永远不要认为自己看的书足够了 ; 要看懂书,仔细看书;遇到完全看不懂的书,请硬着头皮看 ; 别指望看第一遍书就能记住和掌握什么,一次,两次,三次直到搞懂所有的东西;
7.学习Java最好的方法之一就是动手去练习:多多动手,多多练习,你才能快速提升,才能快速成长;
8.不着急,因为学习不是一蹴而就的,只有厚积才能薄发;学习的过程中,记下自己和别人不懂的思路想法;与别人经常交流,记录下在和别人交流时发现的自己忽视或不理解的知识点;
9.首先你得学会出现问题自己想办法找答案,谷歌、百度都是很好的搜索引擎,你只要输入关键字就能找到很多相关资料,用自己的行动学好Java吧。
Java的应用技术
1、在金融业应用的服务器程序Java在金融服务业的应用非常广泛,很多第三方交易系统、银行、金融机构都选择用Java开发,因为相对而言,Java较安全 。大型跨国投资银行用Java来编写前台和后台的电子交易系统,结算和确认系统,数据处理项目以及其他项目。大多数情况下,Java被用在服务器端开发,但多数没有任何前端,它们通常是从一个服务器(上一级)接收数据,处理后发向另一个处理系统(下一级处理)。
2、Android应用许多的 Android应用都是Java程序员开发者开发。虽然 Android运用了不同的JVM以及不同的封装方式,但是代码还是用Java语言所编写。相当一部分的手机中都支持JAVA游戏,这就使很多非编程人员都认识了JAVA。
3、网站Java 在电子商务领域以及网站开发领域占据了一定的席位。开发人员可以运用许多不同的框架来创建web项目,SpringMVC,Struts2.0以及frameworks。即使是简单的 servlet,jsp和以struts为基础的网站在政府项目中也经常被用到。例如医疗救护、保险、教育、国防以及其他的不同部门网站都是以Java为基础来开发的。
4、科学应用Java在科学应用中是很好选择,包括自然语言处理。最主要的原因是因为Java比C++或者其他语言相对其安全性、便携性、可维护性以及其他高级语言的并发性更好
5、嵌入式领域Java在嵌入式领域发展空间很大。在这个平台上,只需130KB就能够使用Java技术(在智能卡或者传感器上)。
6、高频交易的空间Java平台提高了这个平台的特性和即使编译,他同时也能够像 C++ 一样传递数据。正是由于这个原因,Java成为的程序员编写交易平台的语言,因为虽然性能不比C++,但开发人员可以避开安全性,可移植性和可维护性等问题。
7、大数据技术Hadoop以及其他大数据处理技术很多都是用Java,例如Apache的基于Java的HBase和Accumulo以及ElasticSearchas。
篇9:如何能够高效正确的学习jsp
正确的学习jsp的方法
任务0:了解什么是JavaScript
在你真正开始学习JavaScript 之前,花一分钟了解一下什么是JavaScript,它有哪些功能。 JavaScript不是jQuery、Flash或Java。与它们不同,它是一种独立的编程语言。 JavaScript 是浏览器语言(尽管现在不完全是)。主要目的是给静态页面增加交互性。在浏览器里,它不会为你更换PHP或Ruby,也不会更改你的HTML或CSS;你可以把它们串在一起使用。另外,它没有你想的那么难学。 补充说明:你应该听过jQuery,它可能是被使用最广泛的JavaScript 库。也许你还听说过其他比较流行的JavaScript 框架,比如Mootools,,YUI,Dojo 等等。可以将它们统一看做JavaScript辅助工具集;当你使用它们的时候,你还在写JavaScript,但都是些很抽象的JavaScript。它会让你事半功倍。 “你甚至可能听到有人说,你应该先学jQuery(或其他库)再学JavaScript。我很尊重他们但完全不同意这种说法。先把JavaScript 学好再用其他库,你会发现你会做的更好;结果就是,你会编写更好的JavaScript。”
任务1:通过Codecademy.com站点的课程来学习
Codecademy是一个相对较新的网站,其广告语是“最易学的编码方法”。目前,该网站仅有两个课程,“初级编程”和“JavaScript快速入门指南”。沉浸在JavaScript 中是种不错的体验。跟 Try Ruby 练习非常相似,你会学到简短的课程、在浏览器里编码,然后看结果。得到全部分数、打开成就徽章。(Ruby,一种为简单快捷的面向对象编程(面向对象程序设计)而创的脚本语言。) 如果你已熟悉了另一种编程语言,你也许可以先学“JavaScript快速入门指南”;如果这是您第一次编程(HTML和CSS除外),你会发现“初级编程”课程相当有用。Codecademy是一家免费网站,但需要注册。
任务2:appendTo 截屏方法
appendTo 视频有一套特别适合初学者的截屏方法。 如果你想用正确(容易)的方法学习JavaScript,学习这些课程绝对管用。视觉训练总是有效的! “用我们提供的点播内容、务实的训练解决方案来提升自己的技能。无需注册、无需绑定、绝不忽悠。”
任务3:阅读一本好的关于JavaScript 的说明书
一旦你通过Codecademy上的课程来学习,你就会想搞到一本关于JavaScript的详细说明书–介绍所有的类型、运算符、控件架构等等。 如果可以的话,我来介绍几个好的说明书: 《再说JavaScript》 – 这本说明书可在Mozilla开发者网络上找到,语言公正。这本书内容很丰富,有很多代码实例和文段介绍。 《Eloquent JavaScript》 – 该书由Marijn Haverbeke 编写,可免费在线阅读,如果你想弄个硬拷贝可以上亚马逊网站购买。它比MDN说明更详细,因为它不仅涵盖了JavaScript 语言,而且包括编码风格以及在浏览器里使用JavaScript。当然,“eloquent”并非言过其实。(eloquent - 雄辩的、口若悬河的) 《Getting Good with JavaScript》 – 没错,这本书是我写的,但是我介绍这本书是另有原因的。它跟我在前面介绍的两本说明不同;在这本书里我只介绍了编程人员快速掌握编程技巧所需要的部分。此外,它还附带超过6个小时的截屏视频,因此,想要就去看看吧。(当然,这本不是免费的。)
任务4:安装、学习Firebug(或开发人员工具)
一旦你开始在浏览器里使用JavaScript,就需要安装Firebug并熟悉它的性能。Firebug是一款用于Firefox的插件,它能帮你创建和调试网页:对网页开发者来说,它就像外科医生的‘手术刀'。如果你不用Firefox?喜欢Safari 或者Chrome怎么办?没问题:可以查找类似Firebug的内置开发人员工具。 “你可以在Mac地址栏里按选项+命令+I 或者按快捷键Control + Shift + I ,来打开设计工具面板。” 通过打开你选的工具,只需在你喜欢的其中一个网站上点击点击,你就会学到很多东西。这里有一些能加速你学习的资源:FirebugFirebug网站和维基百科Firebug的CSS-技巧说明你应该在Nettuts+上使用Firebug的10大理由。Firebug:从白带到黑带,Tuts+ Marketplace 设计工具设计工具网站Google I/O :由Paul Irish重组的浏览器设计工具Google 浏览器设计工具:Paul Irish 的快速开发12技巧
任务5:读一本有关JavaScript的书籍
现在你已经熟悉了些基础知识,但是还有很多东西要学。尽管我推荐的一些书可能会让你‘破产',但你会发现任何时候我都会推荐4本高质量的书:
前两本是一般的、较深入的JavaScript 资源,它们会让你从简介到较深层次逐步理解;当然,简介里会有一些重叠的说明,但不多:刚好让你看起来很舒服。(注:虽然这些书在亚马逊网站能买到,我已经链接了出版商的网站,因此,你能看看范例章节。) 《JavaScript高级程序设计》- Nicolas C. Zakas 编写,这本书涵盖了它能涵盖的所有内容。如果你以前看过Zakas的任何作品,你会发现他是个不折不扣的天才。除了涵盖了JavaScript语言,这本书还能让您在浏览器里很好的使用JavaScript。 《JavaScript 24-hour Trainer 》由Jeremy McPeak 编撰,该作者也写过Nettuts+。它不仅仅是一本书:还附带了一张长达四小时的教学光碟。全书共43节课,涉及编码句法指导和代码优化。 虽然这些书非常适合编程人员学习JavaScript语言以及如何在浏览器中使用这些语言,但是学无止境。虽然这些书的确进入了一些模式和实练中,我再推荐两本我认为有用的书。1)《JavaScript Patterns 》- Stoyan Stefanov著。我也是刚刚读完这本书,我真希望能尽快读完它。在读过上面的资源之后,你可以学到如何编写JavaScript,但是这本书会教你如何对资源进行重组,这项技能很重要,并非如你想象般简单。2)《JavaScript:The Good Parts 》- Douglas Crockford 著。该书介绍了JavaScript的优缺点。
正确的学习jsp的思维技巧
1.不要让未来的决策阻止你现在前进的方向
很多人学习JavaScript,问的第一个问题往往是“我应该使用哪个框架?”。但是,如果你还没有掌握最最基础的JavaScript,那这显然是一个错误的问题。你将你所有的时间用来研究不同的框架,于是,你开始停滞不前。
帮助摆脱这种陷阱的方法之一是画一个你需要学习的路线图。例如,要想成为一个前端开发者,你的路线图可能是这样的:
进一步分解的话,你可以做一个只有HTML和CSS的功能性web页面。然后像这样一步步列出每个步骤,那么对于现在应该专注于做什么,就一目了然了。你也不会浪费时间去担心应该以后操心的事情。
2.不要让自信诱骗你忘事
快速了解一个概念,也许是学习JavaScript的道路上最影响你进步的事情之一。下面请允许我解释一下。
当你读到某些东西,你觉得的确如此的,那么很可能就会直接跳到下一个内容。然后你觉得接下来这个内容也非常浅显易懂,于是继续往下看。但很快,你会 发现你已经忘记了前面自认为已经掌握的内容,所以只能回过头去温习。你快速地浏览了一遍,感觉又明白了,然后继续前进。但是你又发现自己忘记了别的东西。 你一直处在这个循环中,直到最终迷失了自己。你不由地气馁,想着那先休息一下吧,然而当你休息完了再回来的时候,你发现你已经忘记了所有的内容。
解决这个问题,也很简单,只需要两步:
限制一次学习的量。
实践——实际编写代码。
当你去学习一个新概念的时候,一定要试用它,摆弄它,熟悉它,甚至将它和其他概念结合起来。而且实际输出到示例代码中非常重要,因为这能帮助你消化吸收它。此外,限制一次学习的量,有助于记住资料,道理也很简单,东西越少越好记。
虽然这种学习进程会让你感觉所需的时间更多,但实际上恰恰相反,因为你不再需要走那么多的回头路。我也是经过了很多次惨不忍睹的教训才明白了这个技巧。
3.用正确的心态去做练习
很多人认为反复的练习特别无聊,所以他们通常会选择跳过或尝试走捷径。如果你快进JavaScript练习,那么最终反而需要更多的学习时间。试着让练习变得令人感兴趣,这样是不是就不会那么抗拒呢?
试着转变心态:
如果让你学习一个新的JavaScript概念,却不能试试,会怎么样?你是什么感觉?从我个人而言,我会特别懊恼。这就像一个孩子得到一个新的玩具,却不能玩一样。
当你学习JavaScript中一些新内容的时候,试着将它当作新玩具,新车,新鞋,或者其他任何你有兴趣尝试的东西。然后不要将练习当作工作,要将练习当作是玩耍。用新技能去尝试一些很酷的东西。让你自己都不由的惊叹。然后显摆给你的朋友看。
用一种游戏的心态,你会学得更快,记得更久,拥有更多的乐趣。
4.写代码的时间魔法
在学习JavaScript中最常见的问题是,找不到时间写代码。但是,与此同时,却有大把大把的时间浏览各种网站,如Facebook,YouTube,维基百科和Reddit等。
我有好几次,一开始只是想打开Facebook,看一小会,然后不知不觉就发现已经看了几个小时。这是怎么发生的呢?或许正是因为我并不打算看很长 时间。万事开头难,一旦开了头,后面陷进去就变得容易多了。但是如果有人问我,是否愿意花时间在Facebook上,我会坚决地说不,因为我本身时间就不 够用。然而,只允许看一会会时间往往更容易接受,然后深陷其中。
好消息是,你也可以利用同样的心理来学习写代码。一开始不要想着要编码几小时,因为你永远找不到这么多的时间。就告诉自己你要去写3分钟的代码。这样你永远也不用愁挤不出时间了。
5.思考得更慢,学得更快
这听起来貌似有悖常理,下面我会用一个小故事解释。
我的一个朋友曾经对JavaScript的某个功能感到困惑。于是,我让他详细地说一遍哪些是他知道的,然后给他解释他感到困惑的那部分。不过,当他检查代码片段的时候,我注意到有一段代码,他说得非常仓促。
“等一下!”我说, “慢点讲,每一步都详细地说一下。”
我的朋友继续给我做代码发生了什么的全面总结。
我只好再次叫住他。 “你还是太仓促了。再试一次,但这次,我希望你能从字面上去检查每一行代码,告诉每一行的代码都发生了什么。”
这次,我的朋友终于能够很好地解释代码中正在发生什么。问题的关键是,他终于可以一步一步地检查了代码片段,而不是囫囵吞枣想要一次性理解所有代码。
在类似于这样的情况下,思考得更慢实际上能让你学得更快。
正确的学习jsp的建议
不要总对别人说的给个代码吧!你应该多想想如何做,怎么做?当你自己想出来再参考别人的提示,你就知道自己和别人思路的差异,这样才能进步。
初学者请不要看太多太多的书,只会纷乱你的心思,先找本好书完整系统的学,很多人只对部分功能熟悉而已,不系统功能体系上还是不够的。
看帮助,不要因为很难而自己是初学者所以就不看;多看的参考手册,虽然你可能看不懂,总觉得不够直观。但这才是最根本的东西。
不要被对象、属性、方法等词汇所迷惑;最根本的是先了解最基础知识。
要关注那些细小的细节的问题--他们往往并不那么简单,为了解决它你可能要用到很多很多的东西,帮你回顾知识点;拓宽思路。
知道一点东西,并不能说明你会写脚本,脚本是需要经验积累的。学脚本并不难,JSP、ASP、PHP等等也不过如此--难的是长期坚持实践和不遗余力的博览群书;
学习Java最好的方法之一就是上手动手去练习;永远不要认为自己看的书足够了;要看懂书,仔细看书;遇到完全看不懂的书,请硬着头皮看;别指望看第一遍书就能记住和掌握什么,一次,两次,三次知道搞懂所有的东西;
不着急,因为学习脚本不是一蹴而就的,只有厚积才能薄发。学习的过程中,记下自己喝别人不懂的思路想法。与别人经常交流,记录下在别人交流时发现的自己忽视或不理解的知识点;
首先你得学会出现问题自己想办法找答案,谷歌、百度都是很好的搜索引擎,你只要输入关键字就能找到很多相关资料,用自己的行动学好Java吧。
篇10:JSP实习报告
实习内容:JSP
实习目的:通过JSP的学习,可以独立的编写留言板、上传规格、考试系统、连接SQLserver数据库、以及怎么样配置运行jsp服务器
实习要求:懂得什么是JSP,运行原理,它的基本语法,内置对象,服务端的输出缓冲区,文件流的读取,jsp数据库如:jdbc、odbc、mysql、oracle等,jsp与javaBeans,java Servlet等
JSP是Java Server Pages的缩写,是由Sun公司倡导、许多公司参与,于1999年推出的一种动态网页技术标准。JSP是一个建立安全的、夸平台的先进动态网页技术。
一、JSP工作原理
在一个JSP文件第一次被请求时,JSP引擎把该JSP文件转换成为一个servlet。而这个引擎本身也是一个servlet,在JSWDK或WEBLOGIC中,它就是JspServlet。
JSP引擎先把该JSP文件转换成一个Java源文件,在转换时如果发现jsp文件有任何语法错误,转换过程将中断,并向服务端和客户端输出出错信息;如果转换成功,
JSP引擎用javac把该Java源文件编译成相应的class文件。然后创建一个该SERVLET的实例,该SERVLET的jspInit()方法被执行,jspInit()方法在servlet的生命周期中只被执行一次。然后jspService()方法被调用来处理客户端的请求。对每一个请求,JSP引擎创建一个新的线程来处理该请求。如果有多个客户端同时请求该JSP文件,则JSP引擎会创建多个线程。每个客户端请求对应一个线程。以多线程方式执行可大大降低对系统的资源需求,提高系统的并发量及响应时间.但应该注意多线程的编程限制,由于该servlet始终驻于内存,所以响应是非常快的。
如果.jsp文件被修改了,服务器将根据设置决定是否对该文件重新编译,如果需要重新编译,则将编译结果取代内存中的servlet,并继续上述处理过程。
虽然JSP效率很高,但在第一次调用时由于需要转换和编译而有一些轻微的延迟。
此外,如果在任何时候如果由于系统资源不足的原因,JSP引擎将以某种不确定的方式将servlet从内存中移去。当这种情况发生时jspDestroy()方法首先被调用,
然后servlet实例便被标记加入“垃圾收集”处理。
jspInit()及jspDestory()格式如下:可在jspInit()中进行一些初始化工作,如建立与数据库的连接,或建立网络连接,从配置文件中取一些参数等,在jspDestory()中释放相应的资源。
二、服务端的输出缓冲区
缺省情况下:服务端要输出到客户端的内容,不直接写到客户端,而是先写到一个输出缓冲区中.只有在下面三中情况下,才会把该缓冲区的内容输出到客户端上:
该JSP网页已完成信息的输出
输出缓冲区已满
JSP中调用了out.flush()或response.flushbuffer()
输出缓冲区的大小可以用:或response.setBufferSize()设置,如下:
设置输出缓冲区的大小为1KB。或response.setBufferSize(1);
设置输出缓冲区的大小为0,即不缓冲。或response.setBufferSize(0);
用response.getBufferSize()或out.getBufferSize()可取的输出缓冲区的`大小,单位为字节.
用response.isCommitted()可检查看服务端是否已将数据输出到客户端.
如果返回值是TRUE则已将数据输出到客户端,是FALSE则还没有.
三、服务端输出重定向
有以下3种方法可以做到输出重定向:
RESPONSE.SETREDERECT(“URL”)
该方法通过修改HTTP协议的HEADER部分,对浏览器下达重定向指令的,使浏览器显示重定向网页的内容.
response.sendRedirect(“localhost:7001/”);
下面的方法也能改变HTTP
HEADER属性,它的原理和
1
是一样的.
采用
该方法是利用服务器端先将数据输出到缓冲区的机制,在把缓冲区的内容发送到客户端之前,原来的不发送,改为发送该页面的内容,如果在之前有很多输出,前面的输出已使缓冲区满,将自动输出到客户端,那么该语句将不起作用,这一点应该特别注意.
如下面的例子中(1)会输出index.html的内容,2
不会输出index.html的内容,而是输出out.println(“@@@@@@@@@@@@@@@@@”);
中的内容,并且在服务端会抛出:java.lang.IllegalStateException:
Response
already
committed
异常,但客户端没有任何错误输出。
