利用Serialization实现对象深拷贝

java 代码

private PersonAggregateData copyAggregate(PersonAggregateData original) throws EventsPersonManagementException {

    ByteArrayOutputStream outputBytes = new ByteArrayOutputStream();
    ObjectOutputStream out = null;
    ObjectInputStream in = null;
    PersonAggregateData copy;
    try {
        out = new ObjectOutputStream(outputBytes);
        ByteArrayInputStream inputBytes;
        out.writeObject(original);

        inputBytes = new ByteArrayInputStream(outputBytes.toByteArray());
        in = new ObjectInputStream(inputBytes);
        copy = (PersonAggregateData) in.readObject();
    } catch (IOException e) {
        throw new EventsPersonManagementException("errors occur while copying the PersonAggregateData", e);
    } catch (ClassNotFoundException e) {
        throw new EventsPersonManagementException("errors occur while copying the PersonAggregateData", e);
    } finally {
        try {
            if (out != null) {
                out.close();
            }
            if (in != null) {
                in.close();
            }
        } catch (IOException e) {
            throw new EventsPersonManagementException("errors occur while copying the PersonAggregateData", e);
        }
    }
    return copy;
}
