urlrewrite 配置
在进行链接伪静态时用到了urlrewrite，一个开源的jar包，配置使用：
首先下载jar包导入，下载地址：http://code.google.com/p/urlrewritefilter/downloads/list ，
在web.xml 加入UrlRewriteFilter
<filter>
<filter-name>UrlRewriteFilter</filter-name>
<filter-class>org.tuckey.web.filters.urlrewrite.UrlRewriteFilter</filter-class>
<init-param>
<param-name>logLevel</param-name>
<param-value>WARN</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>UrlRewriteFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
可选的初始化参数 ：
confReloadCheckInterval：间隔冲洗加载时间秒。调试时用这个。
confPath :制定配置文件，不加默认（/WEB-INF/urlrewrite.xml）
statusPath：查看urlrewrite配置的详细，默认/rewrite-status。若在 <url-pattern>/a/*</url-pattern> 则是：/a/rewrite-status
statusEnabled: 若为false,则 statuspath无效，默认true
statusEnabledOnHosts，allowConfSwapViaHttp，modRewriteConf，modRewriteConfText
然后urlrewrite.xml 中配置，下面这个是jar包中自带的配置和说明：
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE urlrewrite PUBLIC "-//tuckey.org//DTD UrlRewrite 3.2//EN"
"http://tuckey.org/res/dtds/urlrewrite3.2.dtd">
<!--
Configuration file for UrlRewriteFilter
http://tuckey.org/urlrewrite/
-->
<urlrewrite>
<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>
<name>简化url</name>
<note>/products/1234 will be passed on to /products/index.jsp?product_id=1234 without the user noticing.</note>
<from>/products/([0-9]+)</from>
<to>/products/index.jsp?product_id=$1</to>
</rule>
<rule>
<note>will pass the request for /some/page.html on to /some/page-for-old-browsers.html only for older
browsers whose user agent srtings match Mozilla/1, Mozilla/2, Mozilla/3 or Mozilla/4</note>
<condition name="user-agent">Mozilla/[1-4]</condition>
<from>/some/page.html</from>
<to>/some/page-for-old-browsers.html</to>
</rule>
<!-- Centralised browser detection -->
<rule>
<condition name="user-agent">Mozilla/[1-4]</condition>
<set type="request" name="browser">moz</set>
</rule>
</urlrewrite>
其中rule 还可以这样
<rule>
<name>test Rule </name>
<note>this is a test normalRule.</note>
<condition type="local-port">8080</condition>
<condition type="dayofweek">1</condition>
<condition type="ampm" operator="less">12</condition>
<condition type="year" operator="greaterorequal">2010</condition>
<run class="com.web.controller.test.Test" method="justRun" jsonhandler="true"/>
<from>/some/olddir/(.*)</from>
<to type="redirect">/very/newdir/$1</to>
</rule>
condition 所支持的type类型，可以在：TypeConverter类中有：
public String getType() {
switch (type) {
case TYPE_TIME:
return "time";
case TYPE_TIME_YEAR:
return "year";
case TYPE_TIME_MONTH:
return "month";
case TYPE_TIME_DAY_OF_MONTH:
return "dayofmonth";
case TYPE_TIME_DAY_OF_WEEK:
return "dayofweek";
case TYPE_TIME_AMPM:
return "ampm";
case TYPE_TIME_HOUR_OF_DAY:
return "hourofday";
case TYPE_TIME_MINUTE:
return "minute";
case TYPE_TIME_SECOND:
return "second";
case TYPE_TIME_MILLISECOND:
return "millisecond";
case TYPE_ATTRIBUTE:
return "attribute";
case TYPE_AUTH_TYPE:
return "auth-type";
case TYPE_CHARACTER_ENCODING:
return "character-encoding";
case TYPE_CONTENT_LENGTH:
return "content-length";
case TYPE_CONTENT_TYPE:
return "content-type";
case TYPE_CONTEXT_PATH:
return "context-path";
case TYPE_COOKIE:
return "cookie";
case TYPE_HEADER:
return "header";
case TYPE_LOCAL_PORT:
return "local-port";
case TYPE_METHOD:
return "method";
case TYPE_PARAMETER:
return "parameter";
case TYPE_PATH_INFO:
return "path-info";
case TYPE_PATH_TRANSLATED:
return "path-translated";
case TYPE_PROTOCOL:
return "protocol";
case TYPE_QUERY_STRING:
return "query-string";
case TYPE_REMOTE_ADDR:
return "remote-addr";
case TYPE_REMOTE_HOST:
return "remote-host";
case TYPE_REMOTE_USER:
return "remote-user";
case TYPE_REQUESTED_SESSION_ID:
return "requested-session-id";
case TYPE_REQUEST_URI:
return "request-uri";
case TYPE_REQUEST_URL:
return "request-url";
case TYPE_SESSION_ATTRIBUTE:
return "session-attribute";
case TYPE_SESSION_IS_NEW:
return "session-isnew";
case TYPE_SERVER_PORT:
return "port";
case TYPE_SERVER_NAME:
return "server-name";
case TYPE_SCHEME:
return "scheme";
case TYPE_USER_IN_ROLE:
return "user-in-role";
case TYPE_EXCEPTION:
return "exception";
default:
return "";
}
}
<run/> 对应的method中的参数必须是一下几种。
{ServletRequest.class, ServletResponse.class},
{ServletRequest.class},
{ServletResponse.class},
{HttpServletRequest.class, HttpServletResponse.class},
{HttpServletRequest.class},
{HttpServletResponse.class}
在类Run中用到反射来验证方法是否存在，反射时默认的参数是以上几种。
在过滤是符合规则 会执行run中对应的方法然后在转向真正的url。
好了，ok。
