Document对象转String，简单记录一下！

Code1:

package com.project.util;import java.io.IOException;import java.io.StringWriter;import org.apache.log4j.Logger;import org.w3c.dom.Document;import com.sun.org.apache.xml.internal.serialize.OutputFormat;import com.sun.org.apache.xml.internal.serialize.XMLSerializer;public class DocumentUtil {	public static Logger log = Logger.getLogger(DocumentUtil.class.getClass());		/**	 * Document 转换为 String 并且进行了格式化缩进	 * 	 * @param doc XML的Document对象	 * @return String	 */	public static String doc2FormatString(Document doc) {			String docString = "";		if(doc != null){			StringWriter stringWriter = new StringWriter();			try{				OutputFormat format = new OutputFormat(doc,"UTF-8",true);				//format.setIndenting(true);//设置是否缩进，默认为true				//format.setIndent(4);//设置缩进字符数				//format.setPreserveSpace(false);//设置是否保持原来的格式,默认为 false				//format.setLineWidth(500);//设置行宽度				XMLSerializer serializer = new XMLSerializer(stringWriter,format);				serializer.asDOMSerializer();				serializer.serialize(doc);				docString = stringWriter.toString();			}catch(Exception e){				e.printStackTrace();			}finally{				if(stringWriter != null){		        	try {						stringWriter.close();					} catch (IOException e) {						e.printStackTrace();					}	        	}			}		}		log.error("XML内容："+docString);		return docString;	}	}

 Code2:

/**	 * org.w3c.dom.Document 转换为 String	 * 	 * @param org.w3c.dom.Document对象	 * @return String	 */	public static String docToString(Document doc) {		String docStr = "";		if(doc!=null){			try{				TransformerFactory transformerFactory = TransformerFactory.newInstance();                				Transformer transformer = transformerFactory.newTransformer();                				transformer.setOutputProperty("encoding", "UTF-8");                				ByteArrayOutputStream outputStream = new ByteArrayOutputStream();                				transformer.transform(new DOMSource(doc), new StreamResult(outputStream));                				//docStr = outputStream.toString();				docStr = outputStream.toString("UTF-8");				System.out.println("\n**********************     【org.w3c.dom.Document对象转XML字符串内容：】       **********************\n"+docStr);			}catch(Exception e){				e.printStackTrace();			}		}		return docStr;	}
