[code="java"]
package test;

import java.beans.XMLDecoder;
import java.beans.XMLEncoder;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;

public class Test {

/**
 * 对象＝〉XML
 * @param xmlFile
 * @param obj
 * @throws Exception
 */
public static void writeObjectToXML(File xmlFile, Object obj) throws Exception {
    XMLEncoder xmlEncoder = null;
    try {
        xmlEncoder = new XMLEncoder(new FileOutputStream(xmlFile));
        xmlEncoder.writeObject(obj);
    } finally {
        if (null != xmlEncoder)
            xmlEncoder.close();
    }
}

/**
 * XML＝〉对象
 * @param xmlFile
 * @throws Exception
 */
public static Object readObjectFromXML(File xmlFile) throws Exception {
    XMLDecoder xmlDecoder = null;

    try{
        xmlDecoder = new XMLDecoder(new FileInputStream(xmlFile));
        return xmlDecoder.readObject();
    }finally{
        if(null != xmlDecoder)
            xmlDecoder.close();
    }
}

public static void main(String[] args) {

    User user = new User();
    user.setId(1);
    user.setName("zhangsan");

    try {
        writeObjectToXML(new File("xml.txt"), user);

        User u = (User)readObjectFromXML(new File("xml.txt"));
        System.out.println(u.getId() + "\t" + u.getName());
    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}

}
