jsp 用urlrewrite 兑现URL 重写-简单

转自：http://hujin1123.iteye.com/blog/255064

是否看到别人的网站网址名都不带后缀名比较酷，比如qq空间的地址，其实用urlrewrite这个包很容易就实现了。
??? 下面是使用说明：

1.下载urlrewrite,官方下载地址：http://tuckey.org/urlrewrite/dist/urlrewritefilter-2.6.zip

2.解压缩文件，压缩包内文件copy到项目中(压缩包位置 -> 项目位置)：

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.将以下代码添加到web.xml里

Xml代码 ?

1. <filter>??
2. ????????<filter-name>UrlRewriteFilter</filter-name>??
3. ????????<filter-class>??
4. ????????????org.tuckey.web.filters.urlrewrite.UrlRewriteFilter ??
5. ????????</filter-class>??
6. ????</filter>??
7. ????<filter-mapping>??
8. ????????<filter-name>UrlRewriteFilter</filter-name>??
9. ????????<url-pattern>/*</url-pattern>??
10. ????</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代码 ?

1. <?xml?version="1.0"?encoding="utf-8"?>? ??
2. <!DOCTYPE?urlrewrite?PUBLIC?"-//tuckey.org//DTD?UrlRewrite?2.6//EN"? ??
3. "http://tuckey.org/res/dtds/urlrewrite2.6.dtd">? ??
4. ??
5. <!--? ??
6. ??
7. Configuration?file?for?UrlRewriteFilter? ??
8. http://tuckey.org/urlrewrite/? ??
9. ??
10. -->? ??
11. <urlrewrite>? ??
12. ????<rule>? ??
13. ????????<from>^/([a-z]+)$</from>? ??
14. ????????<to?type=?"forward"?>/world.jsp?id=$1</to>? ??
15. ????</rule>? ??
16. ????<rule>??
17. ????????<from>^/world/(.*)$</from>??
18. ????????<to>/world.jsp?tid=$1</to>??
19. ????</rule>??
20. ????<rule>??
21. ????????<from>^/(.*).html$</from>??
22. ????????<to>/test1/$1.jsp</to>??
23. ????</rule>??
24. ???? ??
25. ????<outbound-rule>? ??
26. ????????<note>? ??
27. ????????The?outbound-rule?specifies?that?when?response.encodeURL?is?called?(if?you?are?using?JSTL?c:url)? ??
28. ????????the?url?/rewrite-status?will?be?rewritten?to?/test/status/.? ??
29. ???????? ??

33. ????????</note>? ??
34. ????????<from>/rewrite-status</from>? ??
35. ????????<to>/test/status/</to>? ??
36. ????</outbound-rule>??
37. </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 
		in your pages. 
		</note> 
		<from>/rewrite-status</from> 
		<to>/test/status/</to> 
	</outbound-rule>
</urlrewrite> 

rule是url重写规则,from是显示出来的地址,to是映射的实际地址,$1是重写参数,可以为多个,()里是匹配的正则表达式.
好了,在项目中新建world.jsp,启动tomcat,输入
http://localhost:8080/mysite/world/1

mysite是你的项目名

实际上访问的是http://localhost:8080/mysite/world.jsp?tid=1
这样就简单的实现了伪静态的效果

如何快速简单怎么分辨一个页面的URL是真正的静态还是伪静态呢？

?

?静态URL页面右键查看属性， 页面文件大小是有显示的，而且伪静态的是没显示的
