hibernate如何使用原始sql查数据

@Override
      public List<Map<String,Object>> getKnowledgeDetailReplyList(Map<String, Object> params) {
           int num = params.get("num")== null ? Integer.parseInt("0") :Integer.parseInt(params.get("num").toString());
           String recordId =params.get("recordId") == null ? "" :params.get("recordId").toString();
           StringBuffer sbSql = newStringBuffer();
           sbSql.append("selectt.*,rownum");
           sbSql.append("  from (select ke.id,");
           sbSql.append("               ke.sys_user_id,");
           sbSql.append("               ke.evaluate_comment,");
           sbSql.append("               ke.creation_date,");
           sbSql.append("               ke.EVALUATE_LEVEL");
           sbSql.append("          from KM_EVALUATION ke");
           sbSql.append("         where ke.evaluate_status='3' andke.record_id = ?");
           sbSql.append("         order by ke.creation_date desc)t");
           sbSql.append("   where rownum <= ?");
           return this.jdbc.getJdbcTemplate().queryForList(sbSql.toString(),new Object[] {recordId, num});
      }
