明天的明天的明天

首先要在web.xml中聲明一個Filter
 <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>

然后在WEB-INF目錄下新建urlrewrite.xml
在其中進行重寫規則的定義，它使用正則表達式來進行規則的定義

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE urlrewrite PUBLIC "-//tuckey.org//DTD UrlRewrite 2.6//EN"
        "

<!--

    Configuration file for UrlRewriteFilter
    http://tuckey.org/urlrewrite/

-->
<urlrewrite>

        <rule>
            <from>/test.html</from>
            <to type="redirect">%{context-path}/page.html</to>
        </rule>

        <rule>
            <from>/param/(.*)</from>
            <to>/param.jsp?param=$1</to>
        </rule>

</urlrewrite>

上面是我的一個簡單的測試
        <rule>
            <from>/test.html</from>
            <to type="redirect">%{context-path}/page.html</to>
        </rule>
是將test.html的訪問請求轉發給page.html

        <rule>
            <from>/param/(.*)</from>
            <to>/param.jsp?param=$1</to>
        </rule>
將param.jsp?param=111這種請求重寫為/param/111

里面有詳細的例子，大家可以自己看下
