java web目录映射

在eclipse工程中，找到servers文件夹下的server.xml文件，修改内容如下:

 <Host appBase="webapps" autoDeploy="true" name="localhost" unpackWARs="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" pattern="%h %l %u %t &quot;%r&quot; %s %b" prefix="localhost_access_log" suffix=".txt"/>


      <Context docBase="softwarehelp" path="/softwarehelp" reloadable="true" source="org.eclipse.jst.j2ee.server:softwarehelp"/>
      
       <!-- 设置图片虚拟路径[访问时路径为/static_img] -->  
     <Context path="/static_img" docBase="D:\projectdev" reloadable="false" />  
      
      </Host>
