导出单个xml文件：  
\[java\] view plain copy  
      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 plain copy  
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);    
        \}
