一、下载UrlRewriteFilter 上传到WEB-INF/lib目录内

http://central.maven.org/maven2/org/tuckey/urlrewritefilter/4.0.3/urlrewritefilter-4.0.3.jar

二、修改WEB-INF/web.xml

编辑WEB-INF/web.xml 在其它servlet mapping前加入

<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>
    <dispatcher>REQUEST</dispatcher>
    <dispatcher>FORWARD</dispatcher>
</filter-mapping>

三、在WEB-INF下新建urlrewite.xml文件，加入跳转规则【把abc.com修改成自己的域名】

<urlrewrite>
  <rule>
      <name>https redirect</name>
      <condition name="From-Https" operator="notequal">^on</condition>
      <from>^/(.*)</from>
      <to type="permanent-redirect" last="true">https://www.abc.com/$1</to>
  </rule>
</urlrewrite>
