请给我一些建议。谢谢。

 @RequestMapping（/ claim / transportation / download / {docId}）
 public String download（@PathVariable（ docId）整数docId，@ ModelAttribute（dataHolderPrmClaimTransportationSession）DataHolderPrmClaimTransportationSession dataHolderPrmClaimTransportationSession，HttpServletResponse response）{
 System.out.print（docId）;的System.out.println（ 的DocID）; 
 try {
 response.setHeader（Content-Disposition，inline; filename = \+ dataHolderPrmClaimTransportationSession.getUiPrmClaimTransportation（）。getTransportationRecordList（）。get（docId）.getUploadFile（）。getOriginalFilename （）+ \）; 
 System.out.println（DocIDHeader）; 
 System.out.println（dataHolderPrmClaimTransportationSession.getUiPrmClaimTransportation（）。getTransportationRecordList（）。get（docId）.getUploadFile（）。getOriginalFilename（））; 
 OutputStream out = response.getOutputStream（）; 
 System.out.println（out）; 
 response.setContentType（application / pdf）; 
 IOUtils.copy（dataHolderPrmClaimTransportationSession.getUiPrmClaimTransportation（）。getTransportationRecordList（）。get（docId）.getUploadFile（）。getInputStream（），out）;

Please give me some advice .Thanks.

@RequestMapping("/claim/transportation/download/{docId}")
    public String download(@PathVariable("docId") Integer docId, @ModelAttribute("dataHolderPrmClaimTransportationSession") DataHolderPrmClaimTransportationSession dataHolderPrmClaimTransportationSession,HttpServletResponse response){
        System.out.print(docId); System.out.println("DocID");
        try{
            response.setHeader("Content-Disposition", "inline;filename=\""+dataHolderPrmClaimTransportationSession.getUiPrmClaimTransportation().getTransportationRecordList().get(docId).getUploadFile().getOriginalFilename()+"\"");
            System.out.println("DocIDHeader");
            System.out.println(dataHolderPrmClaimTransportationSession.getUiPrmClaimTransportation().getTransportationRecordList().get(docId).getUploadFile().getOriginalFilename());
            OutputStream out=response.getOutputStream();
            System.out.println(out);
            response.setContentType("application/pdf");
            IOUtils.copy(dataHolderPrmClaimTransportationSession.getUiPrmClaimTransportation().getTransportationRecordList().get(docId).getUploadFile().getInputStream(),out);
            out.flush();
            out.close();
        }catch(IOException e)
        {
            logger.error(e.getMessage(),e);
        }

        return null;
    }

<td id="selfTableAttachedFile"><a href="${pageContext.request.contextPath}/hra/prm/claim/transportation/download/${status.index}" target="_blank">${record.uploadFile.originalFilename }</a></td>

解决方案

{pageContext.request.contextPath}/hra/prm/claim/transportation/download/

{status.index}" target="_blank">

{record.uploadFile.originalFilename }</a></td>
