UrlRewrite

<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>   
   



我用的是webwork
所有在webwork的過濾器配置檔案那裡需要加點東西
Java程式碼
<filter-mapping>  
    <filter-name>webwork</filter-name>  
    <url-pattern>/*</url-pattern>  
    <dispatcher>REQUEST</dispatcher>  
       <dispatcher>FORWARD</dispatcher>  
       <dispatcher>INCLUDE</dispatcher>  
</filter-mapping>   
   

然後是在/WEB-INF/下面新建urlrewrite.xml
內容如下:
Java程式碼
  <?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">  
<urlrewrite>  
    <rule>  
        <from>^/register.jsp$</from>  
        <to>/register.action</to>  
    </rule>  
</urlrewrite>  
    

  <?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">
<urlrewrite>
<rule>
<from>^/register.jsp$</from>
<to>/register.action</to>
</rule>
</urlrewrite>


表示訪問register.jsp的時候實際上訪問的是register.action
下面是達人寫的，參考
Java程式碼
