案件讨论回复中出现把多个附件当成一个评论显示，导致分页出错

public Page<BbsArticle> findPageByid(Page<BbsArticle> page,BbsArticle entity) {
        entity.setPage(page);
        List<BbsArticle> l=dao.findbyid(entity);
        List<BbsArticle> new_ls=new ArrayList<BbsArticle>();
        for(BbsArticle bean:l){
            HashMap<String, String> map = new HashMap<String, String>();
            map.put("mainId",bean.getId());
            map.put("type", "08");
            bean.setAttachmentlist(attachmentDao.findListByAll(map)); 
            new_ls.add(bean);        
        }
        page.setList(new_ls);
        return page;
}
