开发网页游戏过程记录18-UrlRewriteFilter配置

在开发过程中需要用到url重写的功能，以实现对url的访问管理。能想到的时使用UrlRewriteFilter来实现，web.xml文件中的配置如下：

<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>log4j</param-value> </init-param> </filter><filter-mapping> <filter-name>UrlRewriteFilter</filter-name> <url-pattern>/*</url-pattern> <dispatcher>REQUEST</dispatcher> <dispatcher>FORWARD</dispatcher> </filter-mapping>配置文件只是有了一个执行环境，我们还需要一个执行的说明书，就是我们得按照什么来进行url重写，需要在WEB-INF下放上urlrewrite.xml这样的文件，这个文件里配置的就是一些重写规则，格式如下：

<?xml version="1.0" encoding="UTF-8"?> <urlrewrite> <!-- rewrite Example --> <!--rule> <from>/games/(.*)</from> <to>/game.do?id=$1</to> </rule --> <!-- ====================================================================== http://game.com/server/serverId == http://game.com/server.do?id=serverId http://game.com/serverlist == http://game.com/serverlist.do =========================================================================== --> <!--rule> <from>/site/serverlist</from> <to>/site/ServerList.do</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>具体的配置还得项目开发完成之后再进行具体配置。
