本文介绍了如何使用Java实现对象的序列化与反序列化操作，包括将对象转换为byte[]数组的过程及从byte[]数组还原为原始对象的方法。

1、序列化

//序列化为byte[]
public static byte[] serialize(Object object) {
    ObjectOutputStream oos = null;
    ByteArrayOutputStream bos = null;
    try {
        bos = new ByteArrayOutputStream();
        oos = new ObjectOutputStream(bos);
        oos.writeObject(object);
        byte[] b = bos.toByteArray();
        return b;
    } catch (IOException e) {
        System.out.println("序列化失败 Exception:" + e.toString());
        return null;
    } finally {
        try {
            if (oos != null) {
                oos.close();
            }
            if (bos != null) {
                bos.close();
            }
        } catch (IOException ex) {
            System.out.println("io could not close:" + ex.toString());
        }
    }
}

2、反序列化

//反序列化为Object
public static Object deserialize(byte[] bytes) {
    ByteArrayInputStream bais = null;
    try {
        // 反序列化
        bais = new ByteArrayInputStream(bytes);
        ObjectInputStream ois = new ObjectInputStream(bais);
        return ois.readObject();
    } catch (IOException | ClassNotFoundException e) {
        System.out.println("bytes Could not deserialize:" + e.toString());
        return null;
    } finally {
        try {
            if (bais != null) {
                bais.close();
            }
        } catch (IOException ex) {
            System.out.println("LogManage Could not serialize:" + ex.toString());
        }
    }
}
