java 对象深度复制

public ComConBen colon() {
        ComConBen copy = null;
        try {
            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            ObjectOutputStream oos = new ObjectOutputStream(baos);
            oos.writeObject(this);
            //将流序列化成对象
            ByteArrayInputStream bais = new ByteArrayInputStream(baos.toByteArray());
            ObjectInputStream ois = new ObjectInputStream(bais);
            copy = (ComConBen) ois.readObject();
        } catch (IOException e) {
            XLog.printExceptionInfo(e);
        } catch (ClassNotFoundException e) {
            XLog.printExceptionInfo(e);
        }
        return copy;
    }

备注:所有对象需实现  Serializable  接口
