java对象深度克隆

java对象深度克隆的方法：

 

 public static final Object deepClone(Object obj){
        if(logger.isDebugEnabled()){
            logger.debug("开始深度克隆对象");
        }
        ByteArrayOutputStream bo = null;
        ObjectOutputStream oo = null;
        ByteArrayInputStream bi = null;
        ObjectInputStream oi = null;
        Object resultObject = null;
        try {
            //将对象写到流里
            if(logger.isDebugEnabled()){
                logger.debug("将对象写入二进制流");
            }
            bo=new ByteArrayOutputStream();
            oo=new ObjectOutputStream(bo);
            oo.writeObject(obj);
            //从流里读出来
            if(logger.isDebugEnabled()){
                logger.debug("在二进制流中将对象读出");
            }
            bi=new ByteArrayInputStream(bo.toByteArray());
            oi=new ObjectInputStream(bi);

            resultObject = oi.readObject();

        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (ClassNotFoundException e) {
            logger.fatal("没有找到对应的类");
        } finally{
            if(logger.isDebugEnabled()){
                logger.debug("关闭流对象");
            }
            try {

                    oo = null;
                }
                if(bo != null){
                    bo.close();
                    bo = null;
                }
            } catch (IOException e) {

            }
