jsp 用urlrewrite 實現URL 重寫

是否看到別人的網站網址名都不帶后綴名比較酷，比如qq空間的地址，其實用urlrewrite這個包很容易就實現了。
下面是使用說明：

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，壓縮包內文件copy到項目中(壓縮包位置 -> 項目位置)：

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

Xml代碼

<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>

<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代碼

<?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>

<?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

		</note> 
		<from>/rewrite-status</from> 
		<to>/test/status/</to> 
	</outbound-rule>
</urlrewrite>

rule是url重寫規則,from是顯示出來的地址,to是映射的實際地址,$1是重寫參數,可以為多個,()里是匹配的正則表達式.
好了,在項目中新建world.jsp,啟動tomcat,輸入
http://localhost:8080/mysite/world/1

mysite是你的項目名

實際上訪問的是http://localhost:8080/mysite/world.jsp?tid=1
