java对象复制

现在网上通用的方法一般为对象的序列化

    /*
     * 复制对象obj，类似于值传递，非引用
     */
    public static Object cloneObject(Object obj) throws Exception{
           ByteArrayOutputStream  byteOut = new ByteArrayOutputStream();  
           ObjectOutputStream out = new ObjectOutputStream(byteOut);  
           out.writeObject(obj);         
           ByteArrayInputStream byteIn = new ByteArrayInputStream(byteOut.toByteArray());  
           ObjectInputStream in =new ObjectInputStream(byteIn);        
           return in.readObject();
    }
