Clone Object by serializing

public class CloneUtils{

// 拷贝一个对象

@SuppressWarnings("unchecked")

public static <T extends Serializable> T clone(T obj) {

// 拷贝产生的对象

T clonedObj = null;

try {

// 读取对象字节数据

ByteArrayOutputStream baos = new ByteArrayOutputStream();

ObjectOutputStream oos = new ObjectOutputStream(baos);

oos.writeObject(obj);

oos.close();

// 分配内存空间，写入原始对象，生成新对象

ByteArrayInputStream bais = new ByteArrayInputStream(baos

.toByteArray());

ObjectInputStream ois = new ObjectInputStream(bais);

// 返回新对象，并做类型转换

clonedObj = (T) ois.readObject();

ois.close();
