How can I convert the java Object into a InputStream?

回答1:

You can use ObjectOutputStream

You write the object (obj in the code below) to the ObjectOutputStream, your object you want to convert to an input stream must implement Serializable.


    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    ObjectOutputStream oos = new ObjectOutputStream(baos);


    oos.writeObject(obj);

    oos.flush();
    oos.close();

    InputStream is = new ByteArrayInputStream(baos.toByteArray());
