JAVA 序列化和反序列化XML

import java.beans.XMLDecoder;
import java.beans.XMLEncoder;
import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;

/**

public class SerializableXmlUtils {
    @SuppressWarnings("unchecked")
    public static <T> T parserXML(String xml) {
        ByteArrayInputStream in = new ByteArrayInputStream(xml.getBytes());
        XMLDecoder decoder = new XMLDecoder(new BufferedInputStream(in));
        decoder.close();
        return (T) decoder.readObject();
    }

    public static <T> String formatXML(T entity) {
        ByteArrayOutputStream out = new ByteArrayOutputStream();
        XMLEncoder encoder = new XMLEncoder(new BufferedOutputStream(out));
        encoder.writeObject(entity);
        encoder.close();
        return out.toString();
    }

    public static void main(String[] args) throws Exception {
        User user = new User();
        user.setId(1);
        user.setName("張三");
        user.setAihao(new String[] { "球", "球2" });
        user.setStudent(new Student(1, "er"));
        String xml = formatXML(user);
        System.out.println("序列化到XML:\n" + xml);
        user = parserXML(xml);
        System.out.println("反序列化Bean:\n" + user);
    }
}

主要是  java.beans包下的對稱序列化，有點類似URL Decoder/Encoder
