XML序列化对象时出现中文乱码

1 public static String ToXmlText(Object obj)throws Exception {
2     ByteArrayOutputStream bos= new ByteArrayOutputStream();
3     XMLEncoder encoder = new XMLEncoder(bos);
4     encoder.writeObject(obj);
5     encoder.flush();
6     encoder.close();
7     return new String(bos.toByteArray(),"UTF-8");
8 }  

解码时，

1 XMLDecoder d = new XMLDecoder(
2         new ByteArrayInputStream(ss.getBytes("UTF-8")));
3 obj = d.readObject();
4 d.close();
