serlet响应中输出xml/html

输出xml： output(resp, resultXML, encoding, "text/xml;charset=" + encoding);

输出html：output(resp, outStr, encoding, "text/html;charset=" + encoding);

 

 

private static void output(HttpServletResponse resp, String outStr, String encoding, String contenttype) {
  OutputStream outputStream = null;
  try {
   outputStream = resp.getOutputStream();
   resp.setContentType(contenttype);
   outputStream.write(outStr.getBytes(encoding));
   outputStream.flush();
  } catch (IOException e) {
  e.printStackTrace();
  } finally {
   if (outputStream != null)
    try {
     outputStream.close();
    } catch (IOException e) {
     e.printStackTrace();
    }
  }
