序列化
public static byte[] serialize(Object object) {
        ObjectOutputStream oos = null;
        ByteArrayOutputStream baos = null;
        try {
            baos = new ByteArrayOutputStream();
            oos = new ObjectOutputStream(baos);
            oos.writeObject(object);
            byte[] bytes = baos.toByteArray();
            return bytes;
        } catch (Exception e) {
        }
        return null;
    }
反序列化
public static Object unserialize(byte[] bytes) {
        ByteArrayInputStream bais = null;
        try {
            bais = new ByteArrayInputStream(bytes);
            ObjectInputStream ois = new ObjectInputStream(bais);
            return ois.readObject();
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }
public static String serialize(Object obj) throws IOException {
            ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
            ObjectOutputStream objectOutputStream;
            objectOutputStream = new ObjectOutputStream(byteArrayOutputStream);
            objectOutputStream.writeObject(obj);
            String string = byteArrayOutputStream.toString("ISO-8859-1");
            objectOutputStream.close();
            byteArrayOutputStream.close();
            return string;
        }
        public static Object serializeToObject(String str) throws IOException, ClassNotFoundException {
            ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(str.getBytes("ISO-8859-1"));
            ObjectInputStream objectInputStream = new ObjectInputStream(byteArrayInputStream);
            Object object = objectInputStream.readObject();
            objectInputStream.close();
            byteArrayInputStream.close();
            return object;
        }
    public static void main(String[] args) throws ClassNotFoundException, IOException {
        byte[] b1 = "hehe".getBytes();
        byte[] b2 = "haha".getBytes();
        List<byte[]> dataByte = new ArrayList<>();
        dataByte.add(b1);dataByte.add(b2);
        String serialize = SpringT.serialize(dataByte);
        System.out.println(serialize.getBytes());
        List<byte[]> serializeToObject = (List<byte[]>) SpringT.serializeToObject(serialize);
        System.out.println(new String(serializeToObject.get(0)));
    }
