public void delete(String newsId) {    logger.debug(StringUtil.append("delete()", BEGIN));    SqlMapClient sqlMapClient=IbatisUtil.getInstance().getSqlMapClient();    try {       sqlMapClient.startTransaction();             //开始事物     sqlMapClient.delete("deleteNews",newsId);           sqlMapClient.commitTransaction();         //提交事物    } catch (SQLException e) {                logger.debug(StringUtil.append("delete()",e.getMessage()));    }finally{      try {        sqlMapClient.endTransaction();             //结束事物      } catch (SQLException e) {        logger.error(StringUtil.append("delete()",e.getMessage()));      }    }    logger.debug(StringUtil.append("delete()",END));  }
