jsp 用urlrewrite 實(shí)現(xiàn)URL 重寫(xiě)是否看到別人的網(wǎng)站網(wǎng)址名都不帶后綴名比較酷,比如qq空間的地址,其實(shí)用urlrewrite這個(gè)包很容易就實(shí)現(xiàn)了。下面是使用說(shuō)明: 1.下載urlrewrite,官方下載地址:http://tuckey.org/urlrewrite/dist/urlrewritefilter-2.6.zip 2.解壓縮文件,壓縮包內(nèi)文件copy到項(xiàng)目中(壓縮包位置 -> 項(xiàng)目位置): urlrewrite-2.6.0-src/webapp/WEB-INF/lib/urlrewrite-2.6.0.jar -> WebRoot/WEB-INF/lib/urlrewrite-2.6.0.jar urlrewrite-2.6.0-src/webapp/WEB-INF/urlrewrite.xml -> WebRoot/WEB-INF/urlrewrite.xml 3.將以下代碼添加到web.xml里
<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>
</filter-mapping>4.修改urlrewrite.xml
<?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"> <!-- Configuration file for UrlRewriteFilter http://tuckey.org/urlrewrite/ --> <urlrewrite> <rule> <from>^/([a-z]+)$</from> <to type= "forward" >/world.jsp?id=$1</to> </rule> <rule> <from>^/world/(.*)$</from> <to>/world.jsp?tid=$1</to> </rule> <rule> <from>^/(.*).html$</from> <to>/test1/$1.jsp</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> rule是url重寫(xiě)規(guī)則,from是顯示出來(lái)的地址,to是映射的實(shí)際地址,$1是重寫(xiě)參數(shù),可以為多個(gè),()里是匹配的正則表達(dá)式. 好了,在項(xiàng)目中新建world.jsp,啟動(dòng)tomcat,輸入 http://localhost:8080/mysite/world/1 mysite是你的項(xiàng)目名 實(shí)際上訪問(wèn)的是http://localhost:8080/mysite/world.jsp?tid=1
