Page export file Times ClientAbortException: java.io.IOException, how to deal with this ?

RT: I use firefox and ie all the normal tests , with 360 and Sogou browser This problem occurs because the export file , but the file can be exported is the background would normally throw this exception. My online search, I found a lot of have this problem, basically no good solution , some say is tomcat problems, some say because of the abolition of the download operation cause. But seemingly did not give solutions.
wood have a look at this great God how to solve it ?
The following my code :
js:

  $("#btnExport").click(function(event) {
                  $("#op").val("export");
                  $("#pageNo").val(1);
                  $("#frmQuery").submit();
                  $("#op").val("");
              });
  

action:

   protected void exportFile(File file) {
          logger.debug("file=" + file);
          ServletOutputStream out = null;
          try {
              byte[] fileData = FileUtils.readFileToByteArray(file);
              String filename = file.getName();
  
              logger.debug("fileData.length=" + fileData.length);
  
              HttpServletResponse response = ServletActionContext.getResponse();
              response.addHeader("Content-Disposition", "attachment; filename="
                      + filename);
              response.addHeader("Content-Length", "" + file.length());
              response.setContentType("application/octet-stream");
              out = response.getOutputStream();
              out.write(fileData);
          } catch (Exception e) {
              logger.error("输出文件时出错! " + file.getAbsolutePath(), e);
          } finally {
              if (out != null) {
                  try {
                      out.close();
                  } catch (IOException e) {
                      e.printStackTrace();
                  }
              }
          }
      }
  

------ Solution ------------------------------------- -------

protected void exportFile(File file) {
          logger.debug("file=" + file);
          HttpServletResponse response = ServletActionContext.getResponse();
          ServletOutputStream out = null;
          try {
              byte[] fileData = FileUtils.readFileToByteArray(file);
              String filename = response.encodeURL(file.getName());
  
              logger.debug("export.file.length=" + fileData.length);
  
              response.reset();
              response.setContentType("application/octet-stream");
              response.setDateHeader("Expires", 0);
              response.setHeader("Cache-Control", "no-transform, max-age=0");
              response.setHeader("Accept-Ranges", "none");
              response.setHeader("Content-Disposition", "attachment; filename="
                      + filename);
              out = response.getOutputStream();
              out.write(fileData);
              out.flush();
          } catch (Exception e) {
              logger.error("输出文件时出错! " + file.getAbsolutePath(), e);
          } finally {
              IOUtils.closeQuietly(out);
          }
      }
