利用Serialization实现对象深拷贝

java 代码

 

1. private PersonAggregateData copyAggregate(PersonAggregateData original) throws EventsPersonManagementException {  
2.       
3.     ByteArrayOutputStream outputBytes = new ByteArrayOutputStream();  
4.     ObjectOutputStream out = null;

6.     PersonAggregateData copy;  
7.     try {  
8.         out = new ObjectOutputStream(outputBytes);  
9.         ByteArrayInputStream inputBytes;  
10.         out.writeObject(original);  
11.   
12.         inputBytes = new ByteArrayInputStream(outputBytes.toByteArray());  
13.         in = new ObjectInputStream(inputBytes);  
14.         copy = (PersonAggregateData) in.readObject();  
15.     } catch (IOException e) {  
16.         throw new EventsPersonManagementException("errors occur while copying the PersonAggregateData", e);
