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
