freeport

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>
  

  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>
  

  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>
  

  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
