从ObjectOutputStream获取对象

Question

我创建了一个ObjectOutputStream

ObjectOutputStream stream = new ObjectOutputStream(new ByteArrayOutputStream());
stream.writeObject(myObject);

但是我现在如何将它转换回Object，甚至是ByteArray？

我试过像这样得到一个ObjectInputStream

ByteArrayOutputStream outputStream = (ByteArrayOutputStream) myProcess.getOutputStream();

final ObjectInputStream objectInputStream = new ObjectInputStream(
    new ByteArrayInputStream(outputStream.toByteArray()));

但是我得到一个编译错误，说它无法将ObjectOutputStream强制转换为ByteArrayOutputStream;然而，ObjectOutputStream似乎没有方法来获取数据？

Answer 1

在这里你是如何做到的

ByteArrayOutputStream baos = new ByteArrayOutputStream();
ObjectOutputStream stream = new ObjectOutputStream(baos);
stream.writeObject(myObject);

ByteArrayInputStream bais = new ByteArrayInputStream(baos.toByteArray());
ObjectInputStream inputStream = new ObjectInputStream(bais);
Object o = inputStream.readObject();
