Url Rewrite Filter 兑现伪静态
伪静态是相对真实静态来讲的.
通常我们为了更好的缓解服务器压力,和增强搜索引擎的友好面.都将文章内容生成静态页面.
但是有的朋友为了实时的显示一些信息.或者还想运用动态脚本解决一些问题.不能用静态的方式来展示网站内容.
但是这就损失了对搜索引擎的友好面.怎么样在两者之间找个中间方法呢,这就产生了伪静态技术.
开源url重定向过滤器, 实现伪静态

Based on the popular and very useful mod_rewrite for apache, UrlRewriteFilter is a Java Web Filter for any J2EE compliant web application server (such as Resin, Orion or Tomcat), which allows you to rewrite URLs before they get to your code. It is a very powerful tool just like Apache's mod_rewrite.
EXAMPLES
Redirect one url
<rule>
<from>/some/old/page.html</from>
<to type="redirect">/very/new/page.html</to>
</rule>
Redirect a directory
<rule>
<from>/some/olddir/(.*)</from>
<to type="redirect">/very/newdir/$1</to>
</rule>
Clean a url
<rule>
<from>/products/([0-9]+)</from>
<to>/products/index.jsp?product_id=$1</to>
</rule>
eg, /products/1234 will be passed on to /products/index.jsp?product_id=1234 without the user noticing.

- Download the zip and extract it into your context's directory ie, so that urlrewrite.xml goes into the WEB-INF directory.
- Add the following to your WEB-INF/web.xml (add it near the top above your servlet mappings (if you have any)): (see filter parameters for more options)
<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> - Add your own configuration to the WEB-INF/urlrewrite.xml that was created.
- Restart the context.
You can visit http://127.0.0.1:8080/rewrite-status (or whatever the address of your local webapp and context) to see output (note: this page is only viewable from localhost).
