Question

//根据解压出来的文件查找文件夹名和截取出来的字符串相同的且层级比当前文件层级小1的文件夹（所属同一个解压文件）
    @SuppressWarnings("unchecked")
    public List<DpFolders> findByDpDocuments(String dpfname, int fileLevel, Documents documents) {
        System.out.println("进入方法进行查找");
        return super.getHibernateTemplate().find("from DpFolder where dpfname="+dpfname+"and fileLevel="+fileLevel+"and documents_id="+documents.getDid());
    }

会报错：
