struts2自动实现过滤

只需在struts.xml

改写为:

 

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">
 
<struts>

 <constant name="struts.custom.i18n.resources" value="globalMessages"/>
 <constant name="struts.i18n.encoding" value="GBK"/>

 <package name="lee" extends="struts-default">
 
  <action name="upload" class="lee.UploadAction">
  <interceptor-ref name="fileUpload">
  <param name="allowedTypes">image/bmp,image/png,image/gif,image/jpeg</param>
  <param name="maximumSize">2000</param>
  </interceptor-ref>
  <interceptor-ref name="defaultStack"></interceptor-ref>
            <param name="savePath">/upload</param>
            <result name="input">/upload.html</result>
   <result>/succ.jsp</result> 
  </action>  
 </package>
</struts>
