URL重写，其实就是把带一大堆参数的url，变成一个看上去很规矩的url,主要目的是为了搜索引擎。举例/viewthread.jsp?id=1234/viewthread.jsp?id=1235/viewthread.jsp?id=1236重写后，可以用/viewthread/1234.htm/viewthread/1235.htm

/viewthread/1236.htm

首先引入urlrewrite-4.0.0.jar【或者其他版本】包，可以从官方下载。

1、web.xml【官方配置】

<?xml version="1.0" encoding="UTF-8"?><web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 	http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">	<display-name></display-name>	<welcome-file-list>		<welcome-file>index.jsp</welcome-file>	</welcome-file-list>	<!-- URL重写配置 -->	<filter>		<filter-name>UrlRewriteFilter</filter-name>		<filter-class>org.tuckey.web.filters.urlrewrite.UrlRewriteFilter</filter-class>		<init-param>			<param-name>logLevel</param-name>			<param-value>WARN</param-value>		</init-param>	</filter>	<filter-mapping>		<filter-name>UrlRewriteFilter</filter-name>		<url-pattern>/*</url-pattern><!-- 拦截所有URL -->	</filter-mapping></web-app>2、urlrewrite.xml
<?xml version="1.0" encoding="utf-8"?><!DOCTYPE urlrewrite PUBLIC "-//tuckey.org//DTD UrlRewrite 3.2//EN"        "http://tuckey.org/res/dtds/urlrewrite3.2.dtd"><!--    Configuration file for UrlRewriteFilter    http://tuckey.org/urlrewrite/--><urlrewrite>     <!--自定义匹配-->     <rule>           <!--  <from>^/admin/(.*)(.*)</from>   -->        <from>admin/([0-9]+)/(.*).shtml/(.*)</from>        <to>/admin_login.jsp?id=$1&amp;name=$2&amp;keyWord=$3</to>      </rule>       <!-- 官方示例-->    <rule>        <note>            The rule means that requests to /test/status/ will be redirected to /rewrite-status            the url will be rewritten.        </note>        <from>/test/status/</from>        <to type="redirect">%{context-path}/rewrite-status</to>    </rule>    <outbound-rule>        <note>            The outbound-rule specifies that when response.encodeURL is called (if you are using JSTL c:url)            the url /rewrite-status will be rewritten to /test/status/.            The above rule and this outbound-rule means that end users should never see the            url /rewrite-status only /test/status/ both in thier location bar and in hyperlinks            in your pages.        </note>        <from>/rewrite-status</from>        <to>/test/status/</to>    </outbound-rule>    <!--    INSTALLATION        in your web.xml add...        <filter>            <filter-name>UrlRewriteFilter</filter-name>            <filter-class>org.tuckey.web.filters.urlrewrite.UrlRewriteFilter</filter-class>            <init-param>                <param-name>logLevel</param-name>                <param-value>WARN</param-value>            </init-param>        </filter>        <filter-mapping>            <filter-name>UrlRewriteFilter</filter-name>            <url-pattern>/*</url-pattern>        </filter-mapping>     EXAMPLES     Redirect one url        <rule>            <from>/some/old/page.html</from>            <to type="redirect">/very/new/page.html</to>        </rule>    Redirect a directory        <rule>            <from>/some/olddir/(.*)</from>            <to type="redirect">/very/newdir/$1</to>        </rule>    Clean a url        <rule>            <from>/PRoducts/([0-9]+)</from>            <to>/products/index.jsp?product_id=$1</to>        </rule>    eg, /products/1234 will be passed on to /products/index.jsp?product_id=1234 without the user noticing.    Browser detection//浏览器检测        <rule>            <condition name="user-agent">Mozilla/[1-4]</condition>            <from>/some/page.html</from>            <to>/some/page-for-old-browsers.html</to>        </rule>    eg, will pass the request for /some/page.html on to /some/page-for-old-browsers.html only for older    browsers whose user agent srtings match Mozilla/1, Mozilla/2, Mozilla/3 or Mozilla/4.

4、admin_login.jsp页面代码：
<body>	Admin Login Page.	<br>	<%=request.getParameter("id")%><br>	<%=request.getParameter("name")%><br>	<%=request.getParameter("keyword")%></body>测试结果：
