序列化和反序列化

1、概念

序列化对象：将对象转换成字节流

反序列化对象：将字节流转换成对象

2、javaApi实现序列化和反序列化

/** * 对象序列化 * @param object 待序列化的对象 * @return 序列化后得到的数组 */public static byte[] serialize(Object object){if(object==null){return null;}ByteArrayOutputStream bos = new ByteArrayOutputStream();try {ObjectOutputStream oos = new ObjectOutputStream(bos);oos.writeObject(object);//讲对象写入输出流byte[] bytes = bos.toByteArray();return bytes;} catch (IOException e) {e.printStackTrace();}return null;}/** * 反序列化对象 * @param bytes 待反序列化的数组 * @return 反序列化后的对象 */public static Object unserialize(byte[] bytes){if(bytes==null){return null;}ByteArrayInputStream bais = new ByteArrayInputStream(bytes);try {ObjectInputStream ois = new ObjectInputStream(bais);Object object = ois.readObject();//输入流读取对象return object;} catch (Exception e) {e.printStackTrace();}return null;}
