Java中如何将Object转换为byte[]呢?

实现思路:
    使用writeObject方法即可将Object写入流中
	然后再转换为字节对象

 public byte[] toByteArray (Object obj) {      
          byte[] bytes = null;      
         ByteArrayOutputStream bos = new ByteArrayOutputStream();      
         try {        
             ObjectOutputStream oos = new ObjectOutputStream(bos);         
             oos.writeObject(obj);        
             oos.flush();         
             bytes = bos.toByteArray ();      
             oos.close();         
             bos.close();        
         } catch (IOException ex) {        
             ex.printStackTrace();   
         }      
         return bytes;    
   }
