用 jdom 解析 xml 文件时如何解决中文问题?如何解析?

<span style="font-size:18px;">package test;
import java.io.*;
public class DOMTest{
private String inFile = "c:\people.xml";
private String outFile = "c:\people.xml";
public static void main(String args[]){
new DOMTest(); 
}
public DOMTest(){
try{
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("王");
org.w3c.dom.Element liu = doc.createElement("刘");
wang.appendChild(doc.createTextNode("我是王老师"));
root.appendChild(wang);
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());
}
}
}
</span>
