Currently, the Q & A system is mainly implemented in the form of Baidu Q & A. It is also used in the combination of campus characteristic modules to enhance the internal Q & A style on campus. The new feature uses urlrewritefilter technology.

I. Role: static dynamic URLs facilitate search engine crawlers to capture your dynamic web pages. Hiding Technology to Improve the portability of websites.

Ii. configuration method and demo

Operating System: Win 7 32-bit flagship Edition

Software environment: myeclipse 9.0 + Tomcat 7.x

 

Step 1: Import urlrewrite-2.6.0.jar, configure web. xml

<! -- Configure urlrewritefilter --> <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> <filter-Name> struts2 </filter-Name> <filter-class> Org. apache. struts2.dispatcher. filterdispatcher </filter-class> </filter> <filter-mapping> <filter-Name> struts2 </filter-Name> <URL-pattern> *. htm </url-pattern> <dispatcher> request </dispatcher> <dispatcher> forward </dispatcher> <dispatcher> include </dispatcher> </filter-mapping> <filter- mapping> <filter-Name> struts2 </filter-Name> <URL-pattern> *. jhtm </url-pattern> <dispatcher> request </dispatcher> <dispatcher> forward </dispatcher> <dispatcher> include </dispatcher> </filter-mapping>

Step 2: Create urlrewrite. xml under the WEB-INF folder

 

<? XML version = "1.0" encoding = "UTF-8"?> <! Doctype urlrewrite public "-// tuckey.org//dtd urlrewrite 2.6 // en" http://tuckey.org/res/dtds/urlrewrite2.6.dtd "> <urlrewrite> <rule> <Note> Home </Note> <from> ^/index.html $ </from> <to>/user/userlist </to> </Rule> <rule> <Note> homepage </Note> <from> ^/$ </from> <to>/user/userlist </to> </Rule> <rule> <Note> administrator background logon </Note> <from> ^/admin/login.htm $ </from> <to>/admin/login/tologin.htm </to> </Rule> <rule> <Note> administrator background </Note> <from> ^/admin (\/*) $ </from> <to>/admin/login/tologin.htm </to> </Rule> </urlrewrite>

Step 3: Add the following code to struts. xml:

<package name="login" namespace="/admin/login" extends="json"><action name="toLogin" class="indexAction" method="toLogin"><result name="success">/WEB-INF/page/admin/login/login.jsp</result></action><action name="doLogin" class="indexAction" method="doLogin"></action></package>

 

Step 4: Write the corresponding action:

/*** Background login ** @ author 正5-5-5 10:04:51 */@ controller @ scope ("prototype") public class indexaction extends baseaction {Private Static final long serialversionuid = 1l; @ autowiredprivate iloginservice loginservice; @ autowiredprivate ipermissionservice perpermissionservice;/*** jump to the logon page ** @ return */Public String tologin () {return success ;} /*** jump to the background homepage ** @ return */Public String index () {getrequest (). setattribute ("adminame", cookieutil. getcookievalue (constant. admin_name, getrequest (); Return success;}/*** exit the system ** @ return */}

Note: When you enter the access URL: http: // localhost: 8087/iask/admin, the suffix ". JSP "does not exist. This address is accessed through urlrewrite. XML filter is parsed to http: // localhost: 8087/iask/admin/login/tologin.htm. the XML file parses the namespace as/admin/login/, and then finds the corresponding action for processing.

 

After processing: the access URL is http: // localhost: 8087/iask/admin.

Step 5: Test

 

URL entered in the test: http: // localhost: 8087/iask/admin1

Http: // localhost: 8087/iask/admintest

Http: // localhost: 8087/iask/admin454 all show Error 404

 

Input: http: // localhost: 8087/iask/admin. The test passes.

 

Test: http: // localhost: 8087/iask/admin/index.htm? R = 0.49279468820504096 test successful
