tomcat配置301重定向
公司域名很多，如：www.wyy.com/wyy.com/wyy.net/blog.wyy.com为了让公司域名统一化，就需要把其他的域名跳转到www.wyy.com
1.简介 urlRewriteFilter是一个用于改写URL的Web过滤器，类似于Apache的mod_rewrite。适用于任何Web应用服务器（如Tomcat,jboss,jetty,Resin，Orion等）。其典型应用就把动态URL静态化，便于搜索引擎爬虫抓取你的动态网页。 2.下载Wget http://urlrewritefilter.googlecode.com/files/urlrewritefilter-4.0.3.jar并放入tomcat的 WEB-INF/lib下3.配置tomcat编辑WEB-INF/web.xml 在其它servlet mapping前加入 <!--301地址重定向-->
<filter>
<filter-name>UrlRewriteFilter</filter-name>
<filter-class>org.tuckey.web.filters.urlrewrite.UrlRewriteFilter</filter-class>
<init-param>
<param-name>confReloadCheckInterval</param-name>
<param-value>60</param-value>
</init-param>
<init-param>
<param-name>confPath</param-name>
<param-value>/WEB-INF/urlrewite.xml</param-value>
</init-param>
<!-- sets up log level (will be logged to context log)
can be: slf4j, TRACE, DEBUG, INFO (default), WARN, ERROR, FATAL,
sysout:{level} (ie, sysout:DEBUG)
if you are having trouble using normal levels use sysout:DEBUG
(default WARN) 设置日志的等级-->
<init-param>
<param-name>logLevel</param-name>
<param-value>DEBUG</param-value>
</init-param>
<!-- you can change status path so that it does not
conflict with your installed apps (note, defaults
to /rewrite-status) note, must start with /设置状态目录，必须以/开始，默认为/rewrite-status -->
<init-param>
<param-name>statusPath</param-name>
<param-value>/status</param-value>
</init-param>
<!-- you can disable status page if desired
can be: true, false (default true) 是否允许状态页面，默认为true-->
<init-param>
<param-name>statusEnabled</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>UrlRewriteFilter</filter-name>
<url-pattern>/*</url-pattern>
<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>
</filter-mapping>
4.添加跳转规则配置文件规则： 跳转规则是在condition匹配前提下才进行重定向。在WEB-INF下新建urlrewite.xml文件，加入跳转规则<urlrewrite>
<rule>
<name>seo redirect</name>
<condition name="host" operator="notequal">^123.57.155.155</condition>
<condition name="host" operator="notequal">^www.wyy.com</condition>
<from>^/(.*)</from>
<to type="permanent-redirect" last="true">https://www.wyy.com/$1</to>
</rule>
</urlrewrite>
