调用之处:
@RequestMapping("/listAgentAwaitRepor") public ListlistAgentAwaitRepor(HttpServletRequest request) throws ServiceException { TableTagBean ttb = TableTagBean.getFromParameter(request); return oldAgentAwaitReportSearchFacade.list(ttb); }
取值之处:
String titleName = ttb.getCondition().get("titleName"); if(!GenericValidator.isBlankOrNull(titleName)) { sql.append(" and biz.biz_title like :bizTitle "); sqlParams.put("bizTitle", "%"+titleName.trim()+"%"); }
