jeecg查询分页

1、页面

<t:datagrid name="decOrderList" checkbox="true" fitColumns="true" title="业务订单表" sortName="createDate" actionUrl="decOrderController.do?datagrid3"  pagination="true"  idField="id" fit="true" queryMode="group">

添加 pagination="true"

2、后台

@RequestMapping(params = "datagrid3")
 public void datagrid3(LdcOrderTaxEntity decOrder,HttpServletRequest request, HttpServletResponse response, DataGrid dataGrid) {
  String invoiceno = request.getParameter("invoiceno");
  String wheresql = "";
  
  if(!"".equals(invoiceno)&&invoiceno!=null){
   wheresql = " and invoiceno = '"+invoiceno+"'";
  }
  String hql = "from LdcOrderTaxEntity where 1=1 " +wheresql;
  List<LdcOrderTaxEntity> ldcOrdertaxList = decOrderService.findHql(hql);
  dataGrid.setResults(ldcOrdertaxList);
 if(decOrderList.size()>0 ) {
   dataGrid.setTotal(decOrderList.size());
  }else{
   dataGrid.setTotal(0);
  }
  TagUtil.datagrid(response, dataGrid);
 }

添加 

if(decOrderList.size()>0 ) {
   dataGrid.setTotal(decOrderList.size());
  }else{
   dataGrid.setTotal(0);
  }
