由此总结出一条心得,查问题的路径:Tomcat官方->找到相关标签->批量搜索Google->取得结果最为高效

例子(Tomcat7或7以下):

<Context useHttpOnly="true" privileged="true" allowLinking="true" aliases="/static=z:/static,/news=z:/news">
...
</Context>

jsp中调用时这样写<jsp:include page=“/news/0/33/10001/shuzijingcai.shtml” flush=“true”></jsp:include>

例子(Tomcat8):

<Context path="" docBase="D:\workspacejava\guess\guessweb\src\main\webapp" reloadable="false" allowLinking="true" privileged="true">
 <Resources>
  <PostResources base="z:/news" className="org.apache.catalina.webresources.DirResourceSet" webAppMount="/news"/>
  <PostResources base="z:/static" className="org.apache.catalina.webresources.DirResourceSet" webAppMount="/static"/>
 </Resources>
</Context>

z为:映射的驱动器名称(可在打开计算机里面看到映射网络驱动器)
base为:待替换目录
webAppMount为:挂载目录,即:Tomcat遇到以/news开头的替换为base指定的值,其中base指定为z:/news/也可行

需要在web.xml里面开启SSI,配置为filter模式也可以,两者选其一即可
也可以直接释放掉Tomcat安装目录下的config下的web.xml配置中的SSI,这个释放和配置在当前项目的web.xml中功能效果是一样的,区别在于一个是全局,一个仅仅针对当前项目
配置如下:

<servlet>
  <servlet-name>ssi</servlet-name>
  <servlet-class>
    org.apache.catalina.ssi.SSIServlet
  </servlet-class>
  <init-param>
    <param-name>buffered</param-name>
    <param-value>1</param-value>
  </init-param>
  <init-param>
    <param-name>debug</param-name>
    <param-value>0</param-value>
  </init-param>
  <init-param>
    <param-name>expires</param-name>
    <param-value>666</param-value>
  </init-param>
  <init-param>
    <param-name>isVirtualWebappRelative</param-name>
    <param-value>false</param-value>
  </init-param>
  <init-param>
    <param-name>inputEncoding</param-name>
    <param-value>UTF-8</param-value>
  </init-param>
  <init-param>
    <param-name>outputEncoding</param-name>
    <param-value>UTF-8</param-value>
  </init-param>
  <load-on-startup>4</load-on-startup>
</servlet>
<servlet-mapping>
 <servlet-name>ssi</servlet-name>
 <url-pattern>*.shtml</url-pattern>
</servlet-mapping>
