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 {
				if(oi != null){
						oi.close();
					oi = null;
				}
				if(bi != null){
					bi.close();
					bi = null;
				}
				if(oo != null){
					oo.close();
					oo = null;
				}
				if(bo != null){
					bo.close();
					bo = null;
				}
			} catch (IOException e) {
				logger.error("",e);
			}
		}
		return resultObject;
	}
