java去掉action,do后缀名，重写url
后缀名不能去掉，只能重写,web.xml的配置如下：
<filter>
<filter-name>UrlRewriteFilter</filter-name>
<filter-class>
org.tuckey.web.filters.urlrewrite.UrlRewriteFilter
</filter-class>
</filter>

<filter-mapping>
<filter-name>UrlRewriteFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
以上是struts1或者jsp的配置
如果是struts2,还要加上:
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>

<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>

</filter-mapping>

然后便是重写URL了,配置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>^/regist$</from>
<to>/regist.action</to>
</rule>

<rule>
<from>^/usr/album-([0-9]+)$</from>
<to>/user/album.action?author=$1</to>
</rule>
</urlrewrite>
