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

[java] view
plain copy

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

[java] view
plain copy

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;

}
