publicclassObjectToByteTesterimplementsSerializable{

privatestaticfinallongserialVersionUID=932872837809539736L;

publicstaticvoidmain(String[]args)throwsIOException{

System.out.println("Bytes字节长度："+objectToBytes(newObjectToByteTester()).length);

}

publicstaticbyte[]objectToBytes(finalSerializableobject)throwsIOException{

ByteArrayOutputStreambaos=newByteArrayOutputStream();

ObjectOutputStreamoos=null;

try{

oos=newObjectOutputStream(baos);

oos.writeObject(object);

oos.flush();

returnbaos.toByteArray();

}finally{

if(oos!=null){

oos.close();

}

if(baos!=null){

baos.close();

}

}

}

}

执行结果如下：

Bytes字节长度：49
