用序列化的方式深拷贝对象

PagedResult<Beehive> beehiveResult = beehiveService.selectHomePageBeehiveList(pageNum,pageSize);
    	
    	String objectString = JSON.toJSONString(beehiveResult);
    	PagedResult<Beehive> cloneBeehivePagedResult = JSON.parseObject(objectString, new TypeReference<PagedResult<Beehive>>(){}.getType());
