struts2 下载不弹出下载对话框

  如下配置可以：

<action name="dowloadfile"  class="course_courseAction">
   <result name="success" type="stream">
     <param name="contentType">application/octet-stream</param>
     <param name="inputName">targetFile</param>
     <param name="contentDisposition">attachment;filename=${courseFile.filename}</param>
     <param name="bufferSize">1024</param>
   </result>
  </action>

 

原来的不可以

  <action name="dowloadfile"  class="course_courseAction">
   <result name="success" type="stream">
     <param name="contentType">application/octet-stream</param>
     <param name="inputName">targetFile</param>
     <param name="contentDisposition">filename=${courseFile.filename}</param>
     <param name="bufferSize">1024</param>
   </result>
  </action>

 

原因 contentDisposition，少了attachment 参数
