UrlRewriteFilter(1)：安装配置

1）添加jar包到WEB-INF/lib中（下载地址：http://www.tuckey.org/urlrewrite/#download），或者Maven则添加如下依赖即可

<dependency>

<groupId>org.tuckey</groupId>

<artifactId>urlrewritefilter</artifactId>

<version>4.0.3</version>

</dependency>

2）在WEB-INF/web.xml中配置UrlRewriterFilter，代码如下

<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>

<dispatcher>REQUEST</dispatcher>

<dispatcher>FORWARD</dispatcher>

</filter-mapping>

3）配置urlrewrite.xml（url重写规则）到WEB-INF下，Maven则在src/main/webapp/WEB-INF下

如下样例模板：

<?xml version="1.0" encoding="utf-8"?>

<!DOCTYPE urlrewrite PUBLIC "-//tuckey.org//DTD UrlRewrite 4.0//EN"

"http://www.tuckey.org/res/dtds/urlrewrite4.0.dtd">

<!--

Configuration file for UrlRewriteFilter
 http://www.tuckey.org/urlrewrite/ 
-->

<urlrewrite>

<rule>

<note>

The rule means that requests to /test/status/ will be redirected to /rewrite-status

the url will be rewritten.

</note>

<from>/test/status/</from>

<to type="redirect">%{context-path}/rewrite-status</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>

<!--

INSTALLATION

in your web.xml add...

<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>

EXAMPLES

Redirect one url

<rule>

<from>/some/old/page.html</from>

<to type="redirect">/very/new/page.html</to>

</rule>

Redirect a directory

<rule>

<from>/some/olddir/(.*)</from>

<to type="redirect">/very/newdir/$1</to>

</rule>

Clean a url

<rule>

<from>/products/([0-9]+)</from>

<to>/products/index.jsp?product_id=$1</to>

</rule>

eg, /products/1234 will be passed on to /products/index.jsp?product_id=1234 without the user noticing.

Browser detection

<rule>

<condition name="user-agent">Mozilla/[1-4]</condition>

<from>/some/page.html</from>

<to>/some/page-for-old-browsers.html</to>

</rule>

eg, will pass the request for /some/page.html on to /some/page-for-old-browsers.html only for older

browsers whose user agent srtings match Mozilla/1, Mozilla/2, Mozilla/3 or Mozilla/4.

Centralised browser detection

<rule>

<condition name="user-agent">Mozilla/[1-4]</condition>

<set type="request" name="browser">moz</set>

</rule>

eg, all requests will be checked against the condition and if matched

request.setAttribute("browser", "moz") will be called.
