搭建ftp服务器在此

设置虚拟路径的代码

在tomcat/conf/下的server.xml打开编辑

在host标签里添加

      <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"
               prefix="localhost_access_log" suffix=".txt"
               pattern="%h %l %u %t "%r" %s %b" />
	<Context path="/sola" docBase="C:\solaphototest" debug="0" reloadable="true" crossContext="true" />
      </Host>

重点是这一句

<Context path="/sola" docBase="C:\solaphototest" debug="0" reloadable="true" crossContext="true" />

path访问路径

docBase文件存放目录

这样可设置docBase目录所在地址和Ftp目录地址一致 这样就可以访问到 ftp里的图片了

访问地址例如localhost:8080/sola/xxx.png
