用jdom创建中文的xml文件的方法

package test;
import java.io.File;
public class DOMTest {
	private String outFile = "c:\\abc\\people.xml";
	public static void main(String[] args) {
		new DOMTest();
	}
	public DOMTest() {
		try {
			File file = new File(outFile); 
			if(!file.exists()){
				file.createNewFile();
			}
			
			javax.xml.parsers.DocumentBuilder builder = javax.xml.parsers.DocumentBuilderFactory.newInstance()
					.newDocumentBuilder();
			org.w3c.dom.Document doc = builder.newDocument();
			org.w3c.dom.Element root = doc.createElement("老师");
			org.w3c.dom.Element wang = doc.createElement("苍");
			org.w3c.dom.Element liu = doc.createElement("刘");
			wang.appendChild(doc.createTextNode("我是苍老师"));
			root.appendChild(wang);
			root.appendChild(liu);
			doc.appendChild(root);
			
			javax.xml.transform.Transformer transformer = javax.xml.transform.TransformerFactory.newInstance()
					.newTransformer();
			transformer.setOutputProperty(javax.xml.transform.OutputKeys.ENCODING, "gb2312");
			transformer.setOutputProperty(javax.xml.transform.OutputKeys.INDENT, "yes");
			transformer.transform(new javax.xml.transform.dom.DOMSource(doc),
					new javax.xml.transform.stream.StreamResult(outFile));
		} catch (Exception e) {
			System.out.println(e.getMessage());
		}
	}
