使用 URLRewrite 重写URL

1、测试环境

 

     下载 URLRewrite，以版本3.1.0为例，将urlrewrite-3.1.0.jar放到classpath下;将下载的文件中的urlrewrite.xml文件放到

     /WEB-INF/下，注意不要修改urlrewrite.xml文件名。

 

2、修改web.xml

 

     在web.xml中增加filter配置：

 <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> <dispatcher>REQUEST</dispatcher> <dispatcher>FORWARD</dispatcher> </filter-mapping>

 

    <init-param />,<dispatcher />为可选项。

 

3、修改urlrewrite.xml

 

<?xml version="1.0" encoding="utf-8"?><!DOCTYPE urlrewrite PUBLIC "-//tuckey.org//DTD UrlRewrite 3.1//EN" "http://tuckey.org/res/dtds/urlrewrite3.1.dtd"><!-- Configuration file for UrlRewriteFilter http://tuckey.org/urlrewrite/--><urlrewrite> <rule> <from>/login.html</from> <to type= "redirect" >/login.jsp</to> </rule> <rule> <from>^/(.*).html$</from> <to type= "forward" >login.jsp?id=$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> <!-- 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. --></urlrewrite>

 

 

  其中 <rule />是定制的规则，<from />是显示的url，<to />是真正请求的url。type = "forward" 地址栏显示from部分（静态化url），type="redirect",地址栏显示to部分（真正请求的地址），注意要保证路径的正确。规则的定制支持正则表达式(如rule 2)。

 

4、测试

 

     测试环境文件目录

      WebRoot

         ---WEB-INF

               ---urlrewrite.xml

         ---login.jsp

 

      启动服务，地址栏输入http://localhost:port/xxx/login.html

 

      rule 1:实际请求为http://localhost:port/xxx/login.jsp

      rule 2:实际请求为http://localhost:port/xxx/login.jsp?id=login

 

     总结：要熟悉正则表达式的运用
