Struts2学习6——UrlRewriter的实现

1、到网站：

​​http://tuckey.org/urlrewrite/​​

下载urlrewritefilter-4.0.3.jar

2、在WEB-INF下新增：urlrewrite.xml

<?xml version="1.0" encoding="utf-8"?>     
<!DOCTYPE urlrewrite PUBLIC "-//tuckey.org//DTD UrlRewrite 2.6//EN"     
"http://tuckey.org/res/dtds/urlrewrite2.6.dtd">     
   
<!--     
   
Configuration file for UrlRewriteFilter     
http://tuckey.org/urlrewrite/     
   
-->     
<urlrewrite> 
    <rule>     
        <from>^/([a-z|_|-|0-9]+)_Lang.js$</from>     
        <to type= "forward" >/$1_Lang.action</to>     
    </rule>  
    <rule>     
        <from>^/([a-z]+)$</from>     
        <to type= "forward" >/world.jsp?id=$1</to>     
    </rule>     
    <rule>   
        <from>^/world/(.*)$</from>   
        <to>/world.jsp?tid=$1</to>   
    </rule>   
    <rule>   
        <from>^/(.*).html$</from>   
        <to>/test1/$1.jsp</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>   
</urlrewrite>

3、修改web.xml

<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> 
        <dispatcher>REQUEST</dispatcher> 
        <dispatcher>FORWARD</dispatcher> 
    </filter-mapping>
