java로 xml 생성

모듈화 하고자 한번 만들어 보았음

@RequestMapping(value = "/xmlWrite", method = RequestMethod.POST)
public String xmlWrite (HttpServletRequest request) throws ParserConfigurationException, SAXException, IOException {
LinkedHashMap <String, String> map = new LinkedHashMap <String,String>();

map.put("systemId", "XXXXXXXX");

map.put("outputTargetTest", "null");

String sTemp = StringUtil.xmlWrite(map);
System.out.println(sTemp);

return sTemp;
