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) {
               logger.error("",e);
           }
       }
       return resultObject;
