黑马毕向东Java课程笔记（35天day29-1——28-19）HTML
本文介绍的HTML标签：列表标签（dl,dt,dd,ol,ul,li），图像标签（img），表格标签（table,tr,td,th,caption），超链接标签（a），框架标签（framset,frame），画中画标签（iframe），表单标签（from，input），几个区域标签（div换行，span不换行，p缩进）
1、HTML概述
Html就是超文本标记语言的简写，是最基础的网页语言。Html语言的特点如下：
1、 Html是通过标签来定义的语言，代码都是由标签所组成；
2、Html代码不用区分大小写；
3、Html代码由开始结束。里面由头部分和体部分两部分组成；
4、头部分是给Html页面增加一些辅助或者属性信息，它里面的内容会最先加载；
5、体部分是真正存放页面数据的地方。
演示，如下代码（注意，HTML不需要编译，只要有能解析它的程序即可打开），我们创建一个demo.html文件，如下：
<html>
<head>
<title>这是标题title>
head>
<body>
这是我的内容，<font size='7' color='red'>啊哈哈font>
body>
html>
2、HTML标签操作思想
HTML将功能封装到标签中，这样我们只需要使用标签就可以使用相应的代码。
多数标签都是有开始标签和结束标签，其中有个别标签因为只有单一功能，或者没有要修饰的内容，可以在标签内结束。
想要对被标签修饰的内容进行更丰富的操作，就用到了标签中的属性，通过对属性值的改变，增加了更多的效果选择。属性与属性值之间用“=”连接，属性值可以用双引号或单引号或者不用引号，一般都会用双引号，或公司规定书写规范。属性与属性之间用空格分开。
格式：
<标签名 属性名='属性值'>数据内容标签名>
<标签名 属性名='属性值' />
操作思想：为了操作数据，都需要对数据进行不同标签的封装，通过标签中的属性对封装的数据进行操作。标签就相当于一个容器。对容器中的数据进行操作，就是在不断的改变容器的属性值。
下面介绍一些标签
因为HTML的所有标签都要闭合，那么“/”就是闭合结束的符号下面的内容是同样的原理。
：换行
：水平线
3、HTML常用工具
我们可以使用Dreamweaver的设计视图，直接进行开发即可。
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>无标题文档title>
head>
<body>
<p>这是设计视图的文字p>
<p><font color="#FF0066">这是演示 的文字font>
p>
<hr />
<h1>这是一级标题h1>
c<dz>a
2<35>7
<br />
c<d z>a
body>
html>
当然我们一般都使用eclipse进行开发，如（35-29-03-14.00解析）。切换到javaee下后，我们选择创建javaEE项目——Create a Dynamic Web proiect。然后在创建的项目下的WebContent文件夹下面可以创建新的HTML项目。项目中各部分存放的内容如下：
JAVA存放目录：SRC
WEB文件目录：WebContent
WEB配置文件：web.xml
视频中所说的Aptana现在eclipse已经找不到相应版本的插件，反正只是一个编译工具而已，没必要纠结。而使用eclipse进行编程也较为麻烦，而且目前我不是很了解步骤，那么就直接使用Dreamweaver进行编程即可。
4、列表标签
关于列表标签及其相应演示如下代码，效果如下图：
<html xmlns="http://www.w3.org/1999/xhtml">
<head>

<hr />
<br />
<a href="#top">回到顶部位置a>
<br />
<a href="#center">回到中间位置a>
body>
html>
8、HTML框架标签
框架使得一个窗体可以显示多个资源，这样可以实现资源的复用。我们在使用Dreamweaver练习框架的时候，应该先创建一个我们想要样式的框架，然后这个框架的“设计界面可以选择你想要编辑的子框架，再装换到“代码”框就可以看到每一个子框架的代码。如果想回到父框架，可以在设计界面使用“alt”+“向上”键回到父框架的代码。

<iframe src="http://www.xxx.com/1.js" height=0 width=0>画中画标签iframe>
body>
html>
9、表单标签
9.1、表单组件——input
表单标签是最常用的标签，用于与服务器端的交互。相应的代码如下
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>无标题文档title>
head>
<body>
<form>
输入名称：<input type="text" name="user" value=""/> <br />
输入密码：<input type="password" name="password" /> <br />
选择性别：
<input type="radio" name="sex" value="man"/>男
<input type="radio" name="sex" value="woman" />女
<br />
选择性别2：
<input type="radio" name="sex2" value="man" />男
<input type="radio" name="sex2" value="woman" checked="checked"/>女
<br />
选择技术：
<input type="checkbox" name="tech" value="java"/>JAVA
<input type="checkbox" name="tech" value="HTML" />HTML
<input type="checkbox" name="tech" value="CSS" />CSS
<br />
选择文件：<input type="file" name="file" />
<br />
<input type="image" src="haha.jpg"/>
<br />
隐藏组件：<input type="hidden" name="myname" value="myvalue" />
<br />
按钮组件：<input type="button" value="按钮" onclick="alert('提示')"/>
<br />
<input type="reset" value="清除数据"/> <input type="submit" value="提交数据" />
form>
body>
html>
9.2、表单组件——select&textarea
相应的代码演示如下
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>无标题文档title>
head>
<body>
<form>
<select name="country">
<option>--选择国家--option>
<option value="usa">美国option>
<option value="un">英国option>
<option value="cn" selected="selected">中国option>
select>
<br/>
<textarea name="text">textarea>
<br/>
<input type="submit" name="提交数据"/>
form>
body>
html>
9.3、表单格式化
上面的界面看起来很不好看，我们使用表格将其美化，相应代码如下：
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>无标题文档title>
head>
<body>
<form>
<table border="1" bordercolor="#0000ff" cellpadding=10 cellspacing=0 width=600>
<tr>
<th colspan="2">注册表单th>
tr>
<tr>
<td> 用户名称：td>
<td> <input type="text" name="user"/>td>
tr>
<tr>
<td> 输入密码：td>
<td> <input type="password" name="psw"/>td>
tr>
<tr>
<td> 确认密码：td>
<td> <input type="password" name="repsw"/>td>
tr>
<tr>
<td> 选择性别：td>
<td>
<input type="radio" name="sex" value="man" checked="checked" />男
<input type="radio" name="sex" value="woman"/>女
td>
tr>
<tr>
<td> 选择技术：td>
<td>
<input type="checkbox" name="tech" value="java"/>JAVA
<input type="checkbox" name="tech" value="HTML"/>HTML
<input type="checkbox" name="tech" value="CSS"/>CSS
td>
tr>
<tr>
<td> 选择国家：td>
<td>
<select name="country">
<option value="null">--选择国家---option>
<option value="usa">美国option>
<option value="cn">中国option>
<option value="en">英国option>
select>
td>
tr>
<tr>
<th colspan="2">
<input type="reset" name="清除数据"/>
<input type="submit" name="提交数据"/>
th>
tr>
table>
form>
body>
html>
9.4、get与post的区别
首先我们用java做一个服务端，用于接收客户端表单提交的信息。代码如下
package test.form;
import java.io.IOException;
import java.io.InputStream;
import java.io.PrintWriter;
import java.net.ServerSocket;
import java.net.Socket;
public class RegServer {
public static void main(String[] args) throws Exception
{
//我们创建一个用于注册的服务端
ServerSocket ss = new ServerSocket(16568);
Socket sk = ss.accept();
// 老规矩，获取输入端ip
String ip = sk.getInetAddress().getHostAddress();
System.out.println(ip + "-----connect");
// 获取输入流，接收数据并转换为字符串打印
InputStream in = sk.getInputStream();
byte[] buf = new byte[1024];
/*
需要特别注意，此处接收的时候不可以写作循环模式，因为我们的表单代码没有关闭在发送完数据后关闭发送流
这样循环结构的read阻塞式方法会一直在等待接收数据，就没办法进行下面的动作，导致无法给客户端反馈数据】
（花了2小时搞这个问题，千万注意。现在还不知道如何修改表单代码来添加关闭表单发送流的动作）
while((len = in.read(buf))!=-1)
{
System.out.println(new String(buf, 0, len));
}
*/
int len = in.read(buf);
System.out.println(new String(buf, 0, len));
// 将接收到的信息反馈给服务端
PrintWriter out = new PrintWriter(sk.getOutputStream(), true);
out.println("注册成功");
System.out.println("反馈完毕");
sk.close();
ss.close();
}
}
其次，表单的HTML代码如下
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>无标题文档title>
head>
<body>
<form action="http://192.168.1.195:16568" method="post">
<table border="1" bordercolor="#0000ff" cellpadding=10 cellspacing=0 width=600>
<tr>
<th colspan="2">注册表单th>
tr>
<tr>
<td> 用户名称：td>
<td> <input type="text" name="user"/>td>
tr>
<tr>
<td> 输入密码：td>
<td> <input type="password" name="psw"/>td>
tr>
<tr>
<td> 确认密码：td>
<td> <input type="password" name="repsw"/>td>
tr>
<tr>
<td> 选择性别：td>
<td>
<input type="radio" name="sex" value="man" checked="checked" />男
<input type="radio" name="sex" value="woman"/>女
td>
tr>
<tr>
<td> 选择技术：td>
<td>
<input type="checkbox" name="tech" value="java"/>JAVA
<input type="checkbox" name="tech" value="HTML"/>HTML
<input type="checkbox" name="tech" value="CSS"/>CSS
td>
tr>
<tr>
<td> 选择国家：td>
<td>
<select name="country">
<option value="null">--选择国家---option>
<option value="usa">美国option>
<option value="cn">中国option>
<option value="en">英国option>
select>
td>
tr>
<tr>
<th colspan="2">
<input type="reset" value="清除数据"/>
<input type="submit" value="提交数据"/>
th>
tr>
table>
form>
body>
html>
10、其他标签
下面说一下html中标签里面定义的一些标签，既头标签。头标签包括：title、base、meta、link。
：指定浏览器的标题栏显示的内容。
<base>：
href属性：指定网页中所有的超链接的目录。可以是本地目录，也可以是网络目录。注意值得结尾处一定要用“/”表示目录。只作用于相对路径的超链接文件。
target属性：指定打开超链接的方式。如_blank表示所有的超链接都用新窗口打开显示。
（如果我们有100个超链接，我们都想通过新窗口打开，那么在<body>里面需要设置100次，而在<head>的<base>标签里面只需要设置1次就可以。）
<meta>:用于模拟http消息
name属性：网页的描述信息。当取keyworda 时，content属性的内容就作为搜索引擎的关键字进行搜索。
http-equiv 属性：模拟Http协议的响应消息头。
例：
<meta http-equiv="refresh" content="3;url=http://www.sina.com.cn" />
（在<head>标签中加上面这一句，我们界面在开启3秒之后会自动跳转到新浪）
<link>：（这个后面我们开发CSS的时候需要使用）
rel属性：描述目标文档与当前文档的关系。
type属性；文档类型。
media：指定目标文档在哪种设备上起作用。
例：
<link rel="stylesheet" "type="text/css" media="gcreen，print" href="a.css"/>

<p> 下面介绍其他的一些内容：</p>
<pre><code>XHTML是可扩展的超文本标记语言（Extensible HyperText Markup Language）。
——XHTML是w3c组织在2000年的时候为了增强HTML推出的，本来是想替代HTML，但是发现Internet上用HTML写的网页太多，未遂！可以理解为它是HTML一个升级版（HTML4.01）。
——XHTML的代码结构更为严谨，是基于XML的一种应用。XML是可扩展标记语言（Extensible Markup language）
——XML是对数据信息的描述，描述数据之间的关系。HTML是数据显示的描述。XML的标签可以自定义，而HTML的标签是固定的。
——XML代码规定的更为严格，如：标签不结束被视为错误。
——XML规范可以被更多的应用程序所解释，将成为一种通用的数据交换语言。
——各个服务器，框架都将XML作为配置文件。。

<p><strong>11、标签的分类</strong><br> 现在我们做界面的布局不需要纯表格了，使用div封装区域，再使用CSS来做布局。</p>

<p><strong>12、HTML标签补充</strong><br> <strong>补充1：web概念概述</strong><br> JavaWeb： 使用Java语言开发基于互联网的项目<br> 软件架构：</p>
<pre><code class="prism language-html">1. C/S: Client/Server 客户端/服务器端
* 在用户本地有一个客户端程序，在远程有一个服务器端程序
* 如：QQ，迅雷...
* 优点：
1. 用户体验好
* 缺点：
1. 开发、安装，部署，维护 麻烦
2. B/S: Browser/Server 浏览器/服务器端
* 只需要一个浏览器，用户通过不同的网址(URL)，客户访问不同的服务器端程序
* 优点：
1. 开发、安装，部署，维护 简单
* 缺点：
1. 如果应用过大，用户的体验可能会受到影响
2. 对硬件要求过高
</code></pre>
<p> B/S架构详解</p>
<pre><code class="prism language-html">* 资源分类：
1. 静态资源：
* 使用静态网页开发技术发布的资源。
* 特点：
* 所有用户访问，得到的结果是一样的。
* 如：文本，图片，音频、视频, HTML,CSS,JavaScript
* 如果用户请求的是静态资源，那么服务器会直接将静态资源发送给浏览器。浏览器中内置了静态资源的解析引擎，可以展示静态资源
2. 动态资源：
* 使用动态网页及时发布的资源。
* 特点：
* 所有用户访问，得到的结果可能不一样。
* 如：jsp/servlet,php,asp...
* 如果用户请求的是动态资源，那么服务器会执行动态资源，转换为静态资源，再发送给浏览器(因为浏览器只能解析静态资源)
我们要学习动态资源，必须先学习静态资源！
静态资源：
* HTML：用于搭建基础网页，展示页面的内容
* CSS：用于美化页面，布局页面
* JavaScript：控制页面的元素，让页面有一些动态的效果
</code></pre>
<p><strong>补充2：概念补充</strong><br> HTML，超文本标记语言，<strong>标记语言不是编程语言</strong>，编程语言是具有一定的逻辑性的，比如有if，else等，而标记语言只要我们写它就会被解析，它没有逻辑性。</p>
<p><strong>补充3：语法补充</strong><br> 语法：</p>
<pre><code class="prism language-html">1. html文档后缀名 .html 或者 .htm
2. 标签分为
1. 围堵标签：有开始标签和结束标签。如 <span class="token tag"><span class="token tag"><span class="token punctuation"><</span>html</span><span class="token punctuation">></span></span> <span class="token tag"><span class="token tag"><span class="token punctuation"></</span>html</span><span class="token punctuation">></span></span>
2. 自闭合标签：开始标签和结束标签在一起。如 <span class="token tag"><span class="token tag"><span class="token punctuation"><</span>br</span><span class="token punctuation">/></span></span>
3. 标签可以嵌套：
需要正确嵌套，不能你中有我，我中有你
错误：<span class="token tag"><span class="token tag"><span class="token punctuation"><</span>a</span><span class="token punctuation">></span></span><span class="token tag"><span class="token tag"><span class="token punctuation"><</span>b</span><span class="token punctuation">></span></span><span class="token tag"><span class="token tag"><span class="token punctuation"></</span>a</span><span class="token punctuation">></span></span><span class="token tag"><span class="token tag"><span class="token punctuation"></</span>b</span><span class="token punctuation">></span></span>
正确：<span class="token tag"><span class="token tag"><span class="token punctuation"><</span>a</span><span class="token punctuation">></span></span><span class="token tag"><span class="token tag"><span class="token punctuation"><</span>b</span><span class="token punctuation">></span></span><span class="token tag"><span class="token tag"><span class="token punctuation"></</span>b</span><span class="token punctuation">></span></span><span class="token tag"><span class="token tag"><span class="token punctuation"></</span>a</span><span class="token punctuation">></span></span>
4. 在开始标签中可以定义属性。属性是由键值对构成，值需要用引号(单双都可)引起来
5. html的标签不区分大小写，但是建议使用小写。
</code></pre>

<h3>文件标签</h3>
<p> 文件标签：构成html最基本的标签</p>
<pre><code class="prism language-html">* html:html文档的根标签
* head：头标签。用于指定html文档的一些属性。引入外部的资源
* title：标题标签。
* body：体标签
* <span class="token doctype"><!DOCTYPE html></span>：html5中定义该文档是html文档

* 属性：
* color：颜色
* size：大小
* face：字体
</code></pre>
<p> 属性定义：</p>
<pre><code class="prism language-html"> * color：
1. 英文单词：red,green,blue
2. rgb(值1，值2，值3)：值的范围：0~255 如 rgb(0,0,255) 三原色分别是：红、绿、蓝
3. #值1值2值3：值的范围：00~FF之间。如： #FF00FF （这种是现在的主要写法）
* width：
1. 数值：width='20' ,数值的单位，默认是 px(像素，与电脑屏幕相关)
2. 数值%：占比相对于父元素的比例（比如某一个元素的父元素是<span class="token tag"><span class="token tag"><span class="token punctuation"><</span>body</span><span class="token punctuation">></span></span>,而<span class="token tag"><span class="token tag"><span class="token punctuation"><</span>body</span><span class="token punctuation">></span></span>占据整个屏幕，那么width='20%'表示这个元素占屏幕宽度的20%）

<p> div和span：</p>
<pre><code class="prism language-html"> * div:每一个div占满一整行。块级标签，既它会换行，同样没有任何样式
* span：文本信息在一行展示，行内标签 内联标签，既span不会换行，也没有任何效果，与CSS结合适用控制区域的样式。

<h3>语义化标签</h3>
<p> 语义化标签：html5中为了提高程序的可读性，提供了一些标签。这两个标签同样没有任何样式，都是为了结合CSS控制样式，方便阅读。</p>
<pre><code class="prism language-html"> 1. <span class="token tag"><span class="token tag"><span class="token punctuation"><</span>header</span><span class="token punctuation">></span></span>：页眉

<pre><code class="prism language-html">1. 确定使用table来完成布局，将数据（图片与文字）封装到行的表格中（既每一行只封装到一个表格中，这样数据的排列较为好看）

3. 如果某一行有多个单元格，则使用（如果一行内封装的数据较多，一个表格之内可以再嵌套表格，为了内容显示有序，同样是将数据放到新表格的单元格内。如果我们都使用单元格表示而不使用这里的表格嵌套，到时候有的地方要合并单元格很麻烦）

<h3>表单标签</h3>
<p> 概念：用于采集用户输入的数据的。用于和服务器进行交互。<br> form：用于定义表单的。可以定义一个范围，范围代表采集用户数据的范围。只有被form包裹起来的数据才会被提交，在form范围之外的数据不会被提交。<strong>表单项中的数据要想被提交：必须指定其name属性</strong>。</p>
<pre><code class="prism language-html">属性：
* action：指定提交数据的URL（既指定将表单数据提交的位置）
* method:指定提交方式
* 分类：一共7种，2种比较常用
* get：
1. 请求参数会在地址栏中显示。会封装到请求行中(HTTP协议后讲解)。
2. 请求参数大小是有限制的。
3. 不太安全。
* post：
2. 请求参数不会再地址栏中显示。会封装在请求体中(HTTP协议后讲解)
2. 请求参数的大小没有限制。
3. 较为安全。
</code></pre>
<p> 表单的各项的性质，参考“.md”文档，前面也介绍了，不再赘述。主要包括input、select、textarea3个标签。（注意区分name属性与value属性，还有一个id属性）</p>
<pre><code class="prism language-html">* input：可以通过type属性值，改变元素展示的样式
* type属性：
* text：文本输入框，默认值
* placeholder：指定输入框的提示信息，当输入框的内容发生变化，会自动清空提示信息
* password：密码输入框
* radio:单选框（name一样，value要指定）
* 注意：
1. 要想让多个单选框实现单选的效果，则多个单选框的name属性值必须一样。
2. 一般会给每一个单选框提供value属性，指定其被选中后提交的值（这点必须注意，单选框与复选框要指定value，服务端才能知道我们发送什么值；同时指定name，表单才能提交）
3. checked属性，可以指定默认值
* checkbox：复选框
* 注意：
1. 一般会给每一个单选框提供value属性，指定其被选中后提交的值
2. checked属性，可以指定默认值
* file：文件选择框
* hidden：隐藏域，用于提交一些信息。
* 按钮：
* submit：提交按钮。可以提交表单
* button：普通按钮
* image：图片提交按钮（和submit具有相同的效果，可以提交数据）
* src属性指定图片的路径
* label：指定输入项的文字描述信息
* 注意：
* label的for属性一般会和 input 的 id属性值 对应。如果对应了，则点击label区域，会让input输入框获取焦点。（只有input才有文本区域，才能通过label获取焦点）
* select: 下拉列表（select中必须设置name，最后的值才会被提交）
* 子元素：option，指定列表项
* 注意，option中可以指定value表示这个选项最后被提交的值，将value设置为0，则这个选项不会被提交（如果不设置value则会默认提交<span class="token tag"><span class="token tag"><span class="token punctuation"><</span>option</span><span class="token punctuation">></span></span>选项<span class="token tag"><span class="token tag"><span class="token punctuation"></</span>option</span><span class="token punctuation">></span></span>中的选项）
* textarea：文本域
* cols：指定列数，每一行有多少个字符
* rows：默认多少行。

<div>mysql 全文模糊查找 便捷解决方案
2013/6/14 by 半仙 alxw4616@Msn.com
目的: 项目需求实现模糊查找.
原则: 查询不能超过 1秒.
问题: 目标表中有超过1千万条记录. 使用like '%str%' 进行模糊查询无法达到性能需求.
解决方案: 使用mysql全文索引.
1.全文索引 : MySQL支持全文索引和搜索功能。MySQL中的全文索</div>

<div>
链表与动态数组的实现方式差不多, 数组适合快速删除某个元素 链表则可以快速的保存数组并且可以是不连续的
单项链表;数据从第一个指向最后一个
实现代码:
//定义动态链表

<div>本文详细介绍Java的范型，写一篇关于范型的博客原因有两个，前几天要写个范型方法(返回值根据传入的类型而定)，竟然想了半天，最后还是从网上找了个范型方法的写法；再者，前一段时间在看Gson, Gson这个JSON包的精华就在于对范型的优雅简单的处理，看它的源代码就比较迷糊，只其然不知其所以然。所以，还是花点时间系统的整理总结下范型吧。

<div>第一个问题，函数是应当返回null还是长度为0的数组（或集合）？
第二个问题，函数输入参数不当时，是异常还是返回null？
先看第一个问题
有两个约定我觉得应当遵守：
1.返回零长度的数组或集合而不是null（详见《Effective Java》）
理由就是，如果返回empty，就可以少了很多not-null判断：
