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 = "
";
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);
}
