urlrewrite 的使用方法

1、下载：
下载地址为http://tuckey.org/urlrewrite/#download
2、配置
将urlrewrite.jar包导入
然后在web.xml配置过滤器

  <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>

   <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的过滤器配置文件那里需要加点东西

 <filter-mapping>
    <filter-name>webwork</filter-name>
    <url-pattern>/*</url-pattern>
    <dispatcher>REQUEST</dispatcher>
       <dispatcher>FORWARD</dispatcher>
       <dispatcher>INCLUDE</dispatcher>
</filter-mapping>

  <filter-mapping>
<filter-name>webwork</filter-name>
<url-pattern>/*</url-pattern>
<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>
<dispatcher>INCLUDE</dispatcher>
</filter-mapping>

然后是在/WEB-INF/下面新建urlrewrite.xml
内容如下:

  <?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>

表示访问register.jsp的时候实际上访问的是register.action
下面是达人写的，参考

<rule>
