springMVC - 页面excel 数据全量导出及按条件导出代码实战

1、JSP部分代码：

//==========================导出excel功能==================================

        <cas:havePerm url="contPageEpt.do">
        //导出功能时间控件
        $('#eptDate').daterangepicker({
            "showDropdowns": true,
            "showCustomRangeLabel": false,
            "alwaysShowCalendars": true,
            "startDate": moment().subtract('days', 7),
            "endDate": moment().subtract('days', 1),
            "opens": "left",
            "drops": "down"
        }, function (start, end, label) {//时间改变后执行该方法
            //alert(label);
        });

        /*搜索条件导出*/
        $("#search_export").on("click", function () {
            var dateRange1 = $('#eptDate').val().replace(/\s/g, "").split("至");
            var startDate1 = dateRange1[0];
            var endDate1 = dateRange1[1];
            var srcContType = $("#srcContType").val();
            var searchKey = $("#searchKey").val();
            window.location = "<c:url value='contPageExport.do'/>" + "?startDate=" + startDate1 + "&endDate=" + endDate1 + "&srcContType=" + srcContType + "&searchKey=" + searchKey;
        })

        /*整体导出*/
        $("#export").on("click", function () {
            var dateRange1 = $('#eptDate').val().replace(/\s/g, "").split("至");
            var startDate1 = dateRange1[0];
            var endDate1 = dateRange1[1];
            var appId = $("#appId").val();
            var srcContType = $("#srcContType").val();
            window.location = "<c:url value='contPageEpt.do'/>" + "?startDate=" + startDate1 + "&endDate=" + endDate1 + "&appId=" + appId + "&srcContType=" + srcContType;
        })
        cas:havePerm>
//=============================导出功能结束====================================  

2、struts.xml 配置

name="contPageEpt" class="bigdata.action.ContPageDayAction" method="export">



name="contPageExport" class="bigdata.action.ContPageDayAction" method="searchExport">

3、action部分代码：

      response.setContentType("application/x-download");
      try {

      } catch (UnsupportedEncodingException e1) {

      }
      ServletOutputStream outputStream = null;

         makeExcel(params, outputStream);
      } catch (IOException e) {

      }
   }

         cell.setCellValue(list.get(i).getIp());
      }

      workbook.write(outputStream);

      outputStream.flush();
      outputStream.close();

4、dao代码部分：

public interface ContPageDayDao {
   public List expList(Map, String> params);
   public List, Object>> searchList(Map, String> searchParams);
 }

5、impl接口实现代码部分：

@Override
public List expList(Map, String> params) {
   List
