对象转化为字节数组

首先对象要继承Serializable接口

private static java.lang.Object ByteToObject(byte[] bytes) { java.lang.Object obj; 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; }

 

public byte[] ObjectToByte(java.lang.Object obj) { byte[] bytes; 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); } 转至：http://rqyyy.javaeye.com/blog/314769
