java对象序列化byte[] and byte[]反序列化对象--转

import java.io.ByteArrayInputStream; import java.io.ByteArrayOutputStream; import java.io.IOException; import java.io.ObjectInputStream; import java.io.ObjectOutputStream; public class ObjectAndByte { /** * 对象转数组 * @param obj * @return */ 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; } /** * 数组转对象 * @param bytes * @return */ public Object toObject (byte[] bytes) { Object obj = null; try { ByteArrayInputStream bis = new ByteArrayInputStream (bytes); ObjectInputStream ois = new ObjectInputStream (bis); obj = ois.readObject(); ois.close(); bis.close(); } catch (IOException ex) { ex.printStackTrace(); } catch (ClassNotFoundException ex) { ex.printStackTrace(); } return obj; } }

问题：

bytes在反序列化为Object的前提是byte[]是通过ObjectOutputStream序列化的，否则直接将一个任意的byte[]转换成Object时会报错，错误信息为：

java.io.StreamCorruptedException: invalid stream header: EFBFBDEF
