idea配置tomcat的虚拟路径， tomcat设置上传文件路径

1.Deploy applications configured in Tomcat instance不要勾上

注意：上传controller的路径要和idea下的真是路径相同

第二种设置虚拟路径的方法

在tomcat\config\server.xml中配置

path="/img" 虚拟路径          docBase图片存放的真实路径

<Context path="image" docBase="D:\imgs" reloadable="true" />

<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 &quot;%r&quot; %s %b" />

  <Context path="image" docBase="D:\imgs" reloadable="true" />
</Host>

如果要在idea中启动

　　.将Deploy applications configured in Tomcat instance勾上
