到底是怎么回事啊，我在百度上找有人說(shuō)，是沒(méi)有實(shí)現(xiàn)java.io.Serializable實(shí)現(xiàn)之后還是解決不了問(wèn)題，還是會(huì)拋出java.io.NotSerializableException求大神指教？

根據(jù)代碼提示，是out.writeObject(ax);這個(gè)方法有錯(cuò)誤，然后你進(jìn)入這個(gè)方法看一下，實(shí)在不行你設(shè)斷點(diǎn)

還要給他一個(gè)序列號(hào)，加上這句
private static final long serialVersionUID = 1L;
