1.利用maven下载相关jar文件，pom文件配置如下：
<dependency> <groupId>org.tuckey</groupId> <artifactId>urlrewritefilter</artifactId> <version>3.2.0</version> </dependency>
2.在web.xml中配置UrlRewriteFilter，配置如下：
<!--urlrewrite过滤器-->
<filter>
<filter-name>UrlRewriteFilter</filter-name>
<filter-class>org.tuckey.web.filters.urlrewrite.UrlRewriteFilter</filter-class>
<init-param>
<param-name>confPath</param-name>
<param-value>/WEB-INF/urlrewrite.xml</param-value>
</init-param>
<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>
<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>
</filter-mapping>
3.添加urlrewirte.xml文件，将文件放在WEB-INF目录下（貌似该文件只能放在WEB-INF下）。配置如下：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE urlrewrite PUBLIC "-//tuckey.org//DTD UrlRewrite 3.2//EN" "\\urlrewrite3.2.dtd">
<urlrewrite>
<rule>
<from>^/([A-Za-z0-9]{6})</from>
<to type="forward">/jump.html?s=$1</to>
</rule>
</urlrewrite>
至此，搞定！
