导出单个xml文件：

[java]view plaincopy 
   
       List<Emr_cda_standard_ntDTO>  resultList = gxwdgfDAO.queryXmlContent(bean,inputData);//字符串来源  
               
             HttpServletResponse response = (HttpServletResponse) inputData.get(ValueConstant.HTTP_RESPONSE);  
               
             String xml = resultList.get(0).getContent();    
               
             //对文件名进行UTF-8编码，并处理编码后空格变成的"+"号  
             String fileName = URLEncoder.encode(resultList.get(0).getCode()+"."+resultList.get(0).getName()+".xml", "UTF-8").replace("+","%20");   
               
             response.setContentType("application/octet-stream;charset=UTF-8");  
             response.setHeader("Content-Disposition", "attachment;filename="+fileName);  
               
             PrintWriter out = response.getWriter();  
             if(xml!=null){  
                 out.print(xml);  
             }else{  
                 out.print("");  
             }  
             out.flush();  
             out.close();  

导出多个xml文件（压缩包形式）：

[java]view plaincopy 
   
 HttpServletRequest req = (HttpServletRequest) inputData.get(ValueConstant.HTTP_REQUEST);  
         HttpServletResponse resp = (HttpServletResponse) inputData.get(ValueConstant.HTTP_RESPONSE);  
         String filename = "";  
         String zipName = "共享文档规范.zip";  
         String xml = "";   
         String path = req.getSession().getServletContext().getRealPath("/");  
         try {  
             List<Emr_cda_standard_ntDTO>  resultList = gxwdgfDAO.queryXmlContent(bean,inputData);//字符串来源  
             resp.setContentType("application/octet-stream;charset=UTF-8");  
             resp.setHeader("Content-Disposition", "attachment;filename="+URLEncoder.encode(zipName, "UTF-8"));  
             String str = "";  
             String rt = "\r\n";  
             ZipOutputStream zos = new ZipOutputStream(resp.getOutputStream());  
             for (Emr_cda_standard_ntDTO emrCdaStandardNtDTO : resultList) {  
                 filename = emrCdaStandardNtDTO.getCode()+"."+emrCdaStandardNtDTO.getName()+".xml";  
                 xml = emrCdaStandardNtDTO.getContent();  
                 str += filename + rt;  
                 zos.putNextEntry(new ZipEntry(filename));  
                   
                 //构造一个临时文件用来压缩  
                 File file=new File(path + filename);//文件对象  
                 PrintWriter out=new PrintWriter(new OutputStreamWriter(new FileOutputStream(file),"UTF-8"));//由文件对象构造一个写出器  
                 if(xml!=null){  
                     out.print(xml);  
                 }else{  
                     out.print("");  
                 }  
                 out.flush();  
                 out.close();  
                   
                 FileInputStream fis = new FileInputStream(file);  
                 byte b[] = new byte[1024];  
                 int n = 0;  
                 while((n = fis.read(b)) != -1){  
                     zos.write(b, 0, n);  
                 }  
                 zos.flush();  
                 fis.close();  
                 file.delete();//删除临时文件  
             }  
             zos.setComment("导出成功:" + rt + str);  
             zos.flush();  
             zos.close();  
         } catch (GeneralException ge) {  
             throw ge;  
         } catch (Exception e) {  
             ExceptionUtil.throwUnknown(e, logger);  
         }
