java中对象与字节数组相互转换

1.首先对象要继承Serializable接口

将字节转换为对象

    public static Object ByteToObject(byte[] bytes) {
Object obj = null;
try {
// bytearray to object
ByteArrayInputStream bi = new ByteArrayInputStream(bytes);
ObjectInputStream oi = new ObjectInputStream(bi);

obj = oi.readObject();
bi.close();
oi.close();
} catch (Exception e) {
System.out.println("translation" + e.getMessage());
e.printStackTrace();
}
        return obj;
    }

将对像转换为字节

public static byte[] ObjectToByte(java.lang.Object obj) {
byte[] bytes = null;
try {
// object to bytearray
ByteArrayOutputStream bo = new ByteArrayOutputStream();
ObjectOutputStream oo = new ObjectOutputStream(bo);
oo.writeObject(obj);

bytes = bo.toByteArray();

bo.close();
oo.close();
} catch (Exception e) {
System.out.println("translation" + e.getMessage());
e.printStackTrace();
}
return bytes;
}
