struts2上傳文件時嚴重過不去，報

Content-Type not allowed: catyIcon "application_xp_terminal.png" "upload__2c2b7695_13a557c978f__8000_00000015.tmp" image/x-png

 

經過查找發現

ie會把 jpg、jpeg翻譯成image/pjpeg，png翻譯成image/x-png

 

配置修改如下：

<!-- 上傳文件過濾攔截器 -->
<interceptor-ref name="fileUpload"> 
   <param name="allowedTypes">
       <!-- IE瀏覽器會把 jpg、jpeg翻譯成image/pjpeg，png翻譯成image/x-png  -->
       image/png,image/gif,image/jpeg,image/jpg,image/bmp,image/ico,image/x-png,image/pjpeg
   </param>
   <param name="maximumSize">500000</param>
</interceptor-ref>
