在tomcat中部署静态资源访问

<Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">

        <!-- SingleSignOn valve, share authentication between web applications
             Documentation at: /docs/config/valve.html -->
        <!--
        <Valve className="org.apache.catalina.authenticator.SingleSignOn" />
        -->

        <!-- Access log processes all example.
             Documentation at: /docs/config/valve.html
             Note: The pattern used is equivalent to using pattern="common" -->
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"

         <!--在Host标签下加入Context标签，path指的是服务器url请求地址（例如127.0.0.1/data），docBase指的是服务器文件的路径，reloadable指的是在omcat不重启的情况下实时同步本地目录-->
        <Context path="/data" docBase="/tmp" reloadable="true" debug="0" crossContext="true"/>
      </Host>
