Idea配置Tomcat虚拟路径

项目中经常使用文件上传,Chrome出于安全考虑不能直接读取硬盘上的资源,此时就需要我们用到虚拟路径

我使用的idea+Tomcat

1.直接更改Tomcat的server.xml

     a.Tomcat中的配置:  添加红色字体

      <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" />
		 <!-- 设置图片虚拟路径[访问时路径为/photo] -->  
         <Context path="/photo" docBase="D:\delelop\temp" reloadable="true" />  

  b.Idea中的配置,勾上Deploy applications configured in Tomcat instance

c.View层代码

  <tr>
            <td>商品图片</td>
            <td>
                <c:if test="${itemsCustom.pic != null}">
                    <img src="/photo/${itemsCustom.pic}" width=100 height=100/><br/>

                </c:if>
                <input type="file" name="items_pic"/>
            </td>
        </tr>

2.不更改Tomcat的配置文件,直接在idea中配置虚拟文件路径

a.不勾上Deploy applications configured in Tomcat instance

b.打开项目Setting设置,(只能对单个文件夹生效)
