1、struts2的版本要高于2.1.8.1
2、需要的jar包有：struts.jar,struts2-convention-plugin-2.1.8.1.jar,struts2-core-2.1.8.1.jar,struts2-dojo-plugin-2.1.8.1.jar,struts2-embeddedjsp-plugin-2.1.8.1.jar,struts2-spring-plugin-2.1.8.1.jar,xwork-core-2.1.6.jar,urlrewrite-3.2.0.jar,aspectjweaver.jar,aspectjrt.jar,aspectjlib.jar,asm-util-2.2.3.jar,asm-commons-2.2.3.jar
3、需要替换struts2 listener：org.apache.struts2.dispatcher.FilterDispatcher 为：org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
并为其添加如下参数：
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>
<dispatcher>INCLUDE</dispatcher>
</filter-mapping>
4、web.xml的编写：
a,请保持与struts2对web.xml的配置建议，即：servlet,filter,listener,..
b,其中listener：
1、org.apache.struts2.dispatcher.ActionContextCleanUp
2、其他listener,如：SiteMesh,apache titles,CharacterEncodingFilter,UrlRewriteFilter......
3、org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
5、完整的web.xml配置内容如下：
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

6、urlrewrite.xml的编写示例：
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE urlrewrite PUBLIC "-//tuckey.org//DTD UrlRewrite 3.2//EN"
"http://tuckey.org/res/dtds/urlrewrite3.2.dtd">
<!--
Configuration file for UrlRewriteFilter
http://tuckey.org/urlrewrite/
-->
<urlrewrite decode-using="utf-8">
<rule>
<from>^/message-u-(.*)\.html$</from>
<to>/testAction.do?username=$1</to>
</rule>
<rule>
<from>^(.*)/a-([0-9]+)\.html$</from>
<to>/index.jsp?fid=$2</to>
</rule>
<rule>
<from>^/b-(username|fid)-([0-9]+)\.html</from>
<to>/index2.jsp?$1=$2</to>
</rule>
<rule>
<from>^(.*)/forum-([0-9]+)-([0-9]+)\.html</from>
<to>/forumdisplay.jsp?fid=$2&page=$3</to>
</rule>
<rule>
<from>^(.*)/thread-([0-9]+)-([0-9]+)-([0-9]+)\.html</from>
<to>/viewthread.jsp?tid=$2&extra=page\%3D$3&page=$4</to>
</rule>
<rule>
<from>^(.*)/tag-(.+)\.html</from>
<to>/tag.jsp?name=$2</to>
</rule>
<rule>
<from>^(.*)/space-(username|uid)-(.+)\.html$</from>
<to>/space.jsp?$2=$3</to>
</rule>
<rule>
<from>^/archiver/fid-([0-9]+)\.html$</from>
<to>/archiver/index.jsp?fid=$1</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>
