推荐答案

如果您打算对对象进行序列化，只需将其设为

If you are thinking about serailising your object, just make it Serializable[^].

public byte[] convert(Object obj) throws IOException {
ObjectOutputStream os = null;

ByteArrayOutputStream byteStream = new ByteArrayOutputStream(5000);
os = new ObjectOutputStream(new BufferedOutputStream(byteStream));
os.flush();
os.writeObject(obj);
os.flush();
byte[] sendBuf = byteStream.toByteArray();
os.close();
return sendBuf;

}

试试这个.

try this.
