/***
* 将Document对象转换成String
* @param document
* @return
*/
public String transformXMLToString(Document document) {
try {
XMLOutputter xmlout = new XMLOutputter();
Format tFormat = Format.getPrettyFormat();
tFormat.setEncoding("GBK");
xmlout.setFormat(tFormat);
ByteArrayOutputStream bo = new ByteArrayOutputStream();
xmlout.output(document, bo);
String xmlStr = bo.toString();
bo.flush();
bo.close();
return xmlStr;
} catch (Exception e) {
LogUtil.getLogger().error(LogUtil.getExceptionDetail(e));
return null;
}
