序列化对象与反序列化

序列化对象

对象转换为字节码 
public  byte[] getBytesFromObject(Serializable obj) {
		 try {
			
				 if (obj == null) {
					 return null;
				 }
				 ByteArrayOutputStream bo = new ByteArrayOutputStream();
				 ObjectOutputStream oo = new ObjectOutputStream(bo);
				 oo.writeObject(obj);
				 return bo.toByteArray();
			} catch (Exception e) {
				// TODO: handle exception
				e.printStackTrace();
				return null;
			}
	    }

反序列化

	/**
	         * 字节码转化为对象
	     * @param objBytes
	     * @return
	     * @throws Exception
	     */
	    public  Object getObjectFromBytes(byte[] objBytes) throws Exception {
	        if (objBytes == null || objBytes.length == 0) {
	            return null;
	        }
	        ByteArrayInputStream bi = new ByteArrayInputStream(objBytes);
	        ObjectInputStream oi = new ObjectInputStream(bi);
	        return oi.readObject();
	    }
