待学习知识点

 

 

1. 对extremtable的了解

<ec:table items="fixedGoods" var="fixedGood" styleClass="clip" border="1" cellpadding="2"

cellspacing="0" action="?" filterable="true" retrieveRowsCallback="limit">

 

public ActionForward listEC(ActionMapping mapping, ActionForm form, HttpServletRequest request,

HttpServletResponse response) {

try {

this.initLocation(request);

LoginUser loginUser = (LoginUser) WebUtils.getRequiredSessionAttribute(request, "loginUser");

Limit limit = ExtremeTablePage.getLimit(request);

Map<String, Object> filterMap = ExtremeTablePage.getFilter(limit);

filterMap.put("acinId", request.getParameter("acinId"));

filterMap.put("operUserId", loginUser.getId());

Map<String, String> sortMap = ExtremeTablePage.getSort(limit);

String sortStr = request.getParameter("field_sort");

sortMap = StringUtils.bindSortFieldToMap(sortStr, sortMap);

this.beForePropertiesSetForList(loginUser, filterMap, sortMap);

Page page = entityManager.findBy(filterMap, sortMap, limit.getPage(), limit.getCurrentRowsDisplayed());

request.setAttribute("totalRows", page.getTotalCount());

request.setAttribute(this.getEntityListName(), page.getResult());

} catch (IllegalStateException e) {

return mapping.findForward("noSession");

} catch (Exception e) {

log.error(e);//项控制台输出日志信息

this.saveError(request, "ecListInputError");//提供错误信息给用户操作界面

request.setAttribute("totalRows", 0);

request.setAttribute(this.getEntityListName(), new ArrayList());

}

return mapping.findForward(this.LIST);

}

2.对spring,ibatis框架的了解
