jsp 用urlrewrite 实现URL 重写【转载】
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
<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>
Xml代码
<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代码
<?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>
 <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代码
<?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>
<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 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">

 <to>/world.jsp?tid=$1</to>
</rule>
<rule>
<from>^/(.*).html$</from>
<to>/test1/$1.jsp</to>
</rule>

<outbound-rule>
<note>

</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
