jdk 1.8 IEDA

设置可以追加写入后，向目标文件序列化多个同一对象，再序列化出来时，因为反序列化时头部信息只读取一次，报出异常。

请问该怎么解决？或者代码写的有问题？

import java.io.*;

/**
 * 完成多个对象的序列化和反序列化

    public static void main(String[] args) {
        Staff staff1 = new Staff("银灰", "近卫", 880, 400);

        Staff staff3 = new Staff("能天使", " 123", 571, 140);
        seralization(staff1);
        seralization(staff2);
        seralization(staff3);

        File file = new File("arknights.txt");
        try {
            deseralization(file);
        } catch (IOException e) {
            e.printStackTrace();
        } catch (ClassNotFoundException e) {
