盖茨走了，
在世人万千的注视中走了，
带着自己的荣耀，
带着属于自己，
也属于世人的"视窗",
走了!
这一走也带走了一个时代!
一个属于盖茨,
也属于微软,
更属于这个世界的时代!
今天是个特别的日子,
不是吗?
一个伟人走了,
在你我的注视中走了...
虽然你我不曾伟大,
不曾笑傲江湖,
但是能够见到历史沧桑,风云变幻
这便够了...
上帝那老头在你我出生之时,
便于安排好你我此生此世的命运.
向前走,不回头,不后悔!!!
今天是个特别的日子,不是吗???

google搜索做的很牛X，推出之后，N多大型网站竞相模拟，差不多和google效果做得一模一样。。。
惊叹，牛人真多。。。
其实google真正用到AJAX最牛X的地方应该是google earth,惊叹中。。。。
去年一直想自己也弄一个，只可以没有时间啊。。。
这段时间空出来了，搞了下。。。只可惜水平有限，有些方面差强人意。。。
见笑了。。。
哪个大牛如果有更好的方案，提供提供，顺便也学习一下。。。
呵呵。。。
由于环境不同，所以搜索只是从一个数组里面进行搜索。。。

以前过滤器可能都只是处理下编码，这次项目中发觉其他成员都是使用过滤器来验证是否登录，然后作相应的转向，发觉真的很不错，不用写一个页面用来判断，然后在每个页面进行包含，也不需要在action中先判断是否登录了再作相应的业务逻辑处理。。。看来还是项目经验不够啊。。。

jstl自带的标签有时候可以满足不了我们的需求，这时我们就要用到自定义函数。。。
新建一个类，定义好所需要的方法。。。 
package com.cw.common;

/**
 * 定义EL自定义函数
 * 
 * @author:陈伟
 * @date:2008-5-15
 * 
 */
public class UFunction {

	/**
	 * 获取一个字符串的长度
	 * 
	 * @author 陈伟
	 * @date 2008-5-15
	 * @param str
	 * @return int
	 */
	public static int getLen(String str) {
		return str.length();
	}

	/**
	 * 截取字符串
	 * 
	 * @author 陈伟
	 * @date 2008-5-15
	 * @param str
	 * @param start
	 * @param end
	 * @return String
	 */
	public static String substr(String str, int start, int end) {
		return str.substring(start, end);
	}

	/**
	 * 两数相除获取整数结果
	 * 
	 * @author 陈伟
	 * @date 2008-5-15
	 * @param first
	 * @param second
	 * @return int
	 */
	public static int chufa(int first, int second) {
		return first / second;
	}
}

再建一个tld文件放在WEB-INF目录下面对其进行配置, 
<?xml version="1.0" encoding="UTF-8"?>
<taglib xmlns="http://java.sun.com/xml/ns/j2ee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-jsptaglibrary_2_0.xsd"
	version="2.0">
	<tlib-version>1.0</tlib-version>
	<short-name>len</short-name>
	<function>
		<description>calculate string length</description><!-- 对这个EL方法的描述  -->
		<name>getLen</name><!-- 调用EL方法的名称 -->
		<function-class>com.cw.common.UFunction</function-class>
		<function-signature>
			int getLen(java.lang.String)
		</function-signature>
		<example>${len:getLen(str)}</example><!-- 例如 -->
	</function>

	<function>
		<description>substring</description>
		<name>substr</name>
		<function-class>com.cw.common.UFunction</function-class>
		<function-signature>
			java.lang.String substr(java.lang.String,int,int)
		</function-signature>
	</function>

	<function>
		<description>chufa</description>
		<name>chufa</name>
		<function-class>com.cw.common.UFunction</function-class>
		<function-signature>int chufa(int,int)</function-signature>
	</function>
</taglib>

最后一步就是调用了 
<%@ page language="java" pageEncoding="gbk"%>
<%@ taglib uri="http://java.sun.com/jstl/core_rt" prefix="c"%>
<%@ taglib uri="/WEB-INF/mytag.tld" prefix="myTag" %>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <body>
  	<c:set var="str" value="1111111111111111111111111111"></c:set>
  	字条串"${str}"的长度是${myTag:getLen(str)}<br/>
  	字条串"${str}"截取前5个字符：${myTag:substr(str,0,5)}<br/>
  	5除以3取整数是:${myTag:chufa(5,3) }
  
  </body>
</html>

首先，要把applicationContext.xml加载一内存..
web.xml
================
<!-- 根据需要可能要添加侦听器  -->
<listener>
		<listener-class>
			org.springframework.web.context.ContextLoaderListener
		</listener-class>
	</listener>

<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>/WEB-INF/applicationContext.xml,/WEB-INF/applicationContext-chikaren.xml,/WEB-INF/applicationContext-fakaren.xml,/WEB-INF/applicationContext-geren.xml,/WEB-INF/applicationContext-shanghu.xml,/WEB-INF/applicationContext-yunying.xml</param-value>
</context-param>

把struts-config.xml中的Action都定义成org.springframework.web.struts.DelegatingActionProxy,这是一个代理action,
请求都会先提交给这个代理action,然后这个代理action会提交给内存中applicationContext.xml配置与当前请求路径同名path的bean,这里同名的bean才是struts框架下的action,真正的业务在这里实现.同时applicationContext.xml作为一个插件配置在struts-config.xml文件中...
struts-config-geren.xml
=======================
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">

在框架盛行的年代，虽然servlet这些东西都是些最基本的东西
但是在实际的项目开发过程中都很少再用到，当然，除非你们公司不用框架。。。
今天在CSDN上看了个例子，一个家伙问登录怎么实现。。。
不少人给出了思路，还贴出代码
有人贴出了这样一行SQL语句
select count(*) from 用户表 where 用户名字段="用户名" and 密码字段="密码"
如果数据库的密码没有加密的话，很容易SQL注入攻击。。。
只要密码输成a' or 'a'='a 之类的。。。
后来写了个DEMO jsp+servlet
登录之后的
在servlet中输出登录后的结果，就是用out.println();
此时乱码出来了。。。
页面编码:gbk
加了下面两行代码也不行。。。
response.setContentType("text/html;charset=gbk");
response.setCharacterEncoding("gbk");
到网上找啊找啊。。。
最后终于在快放弃的时候找到了。。。
设置下输出流的编码格式
PrintWriter out = new PrintWriter(new

OutputStreamWriter(response.getOutputStream(),"gbk"));
OK，搞定。。。
呵呵，又进步了。。。

关于js验证:
//获取对象，如果使用传统DOM获取的话，提交的时候第一次的值不会改变，只有点击第二次才会//获取正常的值
var contentsElement=FCKeditorAPI.GetInstance("contents");
	var contents =contentsElement.GetXHTML();
	if(contents=="" || contents.length==0){
		alert("\u5185\u5bb9\u4e0d\u80fd\u4e3a\u7a7a!");
//获取焦点，注意F一定要是大写
		contentsElement.Focus();
		return false;
	}
	else if(contents.length>1000){
		alert("\u5185\u5bb9\u957f\u5ea6\u4e0d\u80fd\u8d85\u8fc71000\u4e2a\u5b57\u7b26!");
		contentsElement.Focus();
		return false;
	}

关于使用:
附件是一个简单的配置，保留了所有功能。。。版本2.3

写了下面这样一个JS方法，要做一个无刷新效果，上面加了一行注释
//发送请求，传递省ID获取下面所有的市
function sendProId(obj) {
var o = obj;
var id = o.value;
if (id == "0") {
var city = document.getElementById("city");
city.innerHTML = "";
return;
}
sendAjaxRequest("/LhCard/GeRen/uarea.do?method=getcity", "id", id, showcities);
}

可是调用的时候，一直报找不到对象，当然这个方法所在的JS在页面中也引用了。。。
找啊找啊。。。搞了一个小时不知道问题出在哪。。。
没办法，最后开启脚本调试，用VS2008调试，
一看，乖乖，不得了。。。
浏览器把上面那个方法解析成下面这样
//发送请求，传递省ID获取下面所有的市function sendProId(obj) {
var o = obj;
var id = o.value;
if (id == "0") {
var city = document.getElementById("city");
city.innerHTML = "";
return;
}
sendAjaxRequest("/LhCard/GeRen/uarea.do?method=getcity", "id", id, showcities);
}

哎，怪不得找不到对象。。。
最后加一个空行搞定。。。
//发送请求，传递省ID获取下面所有的市

function sendProId(obj) {
var o = obj;
var id = o.value;
if (id == "0") {
var city = document.getElementById("city");
city.innerHTML = "";
return;
}
sendAjaxRequest("/LhCard/GeRen/uarea.do?method=getcity", "id", id, showcities);
}

郁闷。。。

项目中要格式化日期，到网上搜了下。。。
用<fmt:formatDate value="${ml.sendDate}" pattern="yyyy-MM-dd HH:mm:ss"/>
添加标签引用：<%@ taglib prefix="fmt" uri="http://java.sun.com/jstl/fmt" %>对应tld文件就是/WEB-INF/fmt-1_0-rt.tld
可是就是报错。。。
郁闷了半天。。。
最后发现问题出在标签引用上。。。
换了下面两个引用都可以。。。
<%@ taglib uri="/WEB-INF/fmt-1_0-rt.tld" prefix="fmt"%>
对应uri:http://java.sun.com/jstl/fmt_rt
还有
<%@ taglib uri="/WEB-INF/fmt.tld" prefix="fmt"%>
对应uri:http://java.sun.com/jsp/jstl/fmt

<fmt:formatNumber pattern=".00" value="11"></fmt:formatNumber>
输出：11.00
<fmt:formatNumber pattern="#" value="11.23"></fmt:formatNumber>
输出：11

项目中生成订单要用年月日6位字符加5位的一个流水号，先要到订单流水表中去查询当天是否有下订单，如果有流水号就在加1，如果没有就随机生成一个，根据日期去查询，可用日期字符串，hibernate会自动转化。。。

其中，currentDate是date数据类型...

Session ses = dao.getSession();
  try {
   Query query = ses
     .createQuery("select max(usn.serialNumber) from USerialNumber usn where usn.currentDate='"
       + DateTime.getCurrentDate()
       + "'");
   List list = query.list();
   if (list == null || list.size() == 0)
    System.out.println("没有找到相关记录");
   else {
    String maxNum=list.get(0).toString();
    System.out.println("找到记录：最大的流水号===="+maxNum);
      //+ usn.getSerialNumber().intValue());
   }
  } catch (HibernateException e) {
   e.printStackTrace();
  } catch (Exception e) {
   e.printStackTrace();
  }

删除某些数据后，为了更好的用户体验感，可能无需提示成功，直接跳转后重新显示删除后剩余的数据，此时可以将一次请求定义成一个转向。。。
