jfinal中excel表格导出

  今天工作中遇到了excel表格导出的操作,还好有写好的模板,不然我也是焦头烂额,下面记录一下excel表格导出的操作步骤,同时用来给正在学习jfinal的小伙伴一些参考和学习。

  首先我们需要把表格查询出并且显示在页面上,下面是页面跳转时经过的Controller:(这里包含条件查询,所以获取信息比较复杂,全部查询只需要将获取到的pageUtils 传到前台即可,不需要添加多余的查询条件,在这里传给前台的变量名我叫他page)

public void index(){         PageUtils pageUtils = getPageParameter();         String where = " where 1=1 ";         //获取当前时间         String nowDate =DateUtils.getDate();         if(pageUtils.getMap().get("orderNo")!=null&&!pageUtils.getMap().get("orderNo").toString().trim().equals("")){             where = where + " and order_no like '%"+pageUtils.getMap().get("orderNo")+ "%' ";         }         if(pageUtils.getMap().get("customerName")!=null&&!pageUtils.getMap().get("customerName").toString().trim().equals("")){             where = where + " and customer_name like '%"+pageUtils.getMap().get("customerName")+"%'";         }          if(pageUtils.getMap().get("shipmentDate")!=null&&!pageUtils.getMap().get("shipmentDate").toString().trim().equals("")){             where = where + " and shipment_date = '"+pageUtils.getMap().get("shipmentDate")+"'";         }         if(pageUtils.getMap().get("isship")!=null&&!pageUtils.getMap().get("isship").toString().trim().equals("")){             if(pageUtils.getMap().get("isship").equals("1")){                 where = where + " and Tknum is not null ";             }else if (pageUtils.getMap().get("isship").equals("3")){                 where = where + " and ship_type!=5 and arrive_date<'"+nowDate+"' ";             }else{                 where = where + " and Tknum is null ";             }         }             if(pageUtils.getMap().get("shipType")!=null&&!pageUtils.getMap().get("shipType").toString().trim().equals("")){             if(pageUtils.getMap().get("shipType").equals("1")){                 where = where + " and ship_type =5 ";             }else{                 where = where + " and ship_type !=5 ";             }         }         if(pageUtils.getMap().get("ishd")!=null&&!pageUtils.getMap().get("ishd").toString().trim().equals("")){             if(pageUtils.getMap().get("ishd").equals("1")){                 where = where + " and img is not null ";             }else{                 where = where + " and img is null ";             }         }             where += " order by arrive_date desc ";         pageUtils.initialize(TMSOrderList.dao.paginate(pageUtils.getPageNo(),                 pageUtils.getPageSize(), "select * ",                 " from TMS_Order_List"+where+ pageUtils.getOrderBySql()));         if(pageUtils.getList().size()==0&&pageUtils.getPageNo()!=1){             pageUtils.setPageNo(1);              pageUtils.initialize(TMSOrderList.dao.paginate(pageUtils.getPageNo(),                     pageUtils.getPageSize(), "select * ",                     " from TMS_Order_List "+where+pageUtils.getOrderBySql()));         }                  setAttr("page", pageUtils);         setAttr("nowDate", nowDate);         render("reportList.jsp");     }

  在上面我们获取到了表格信息(实体类和model我就不用写了吧),这里传到前台两个变量,和一个需要返回的页面,这里当前时间你们可能不需要,之后就是在页面接收这个值:(这里因为连表查询所以将page这个值拆开了两次,如果不

  需要链表,直接<c:foreach>循环输出就好了,不需要<c:set>)

  之后就是重点了,excel表格导出,我们可以看到这个页面的最顶端有个导出按钮,导出按钮监听了点击事件onclick="exportExcel()",之后我们可以在页面的上方写JavaScript写一个方法:

function exportExcel (){         $("#searchForm").attr("action","${ctx}/tms/report/exportExcel").submit();     }

  这里写的这个方法是跳转到tms下面report这个controller下的exportExcel方法,这个方法是这样写的:

/**      * 导出excel      */     public void exportExcel(){ //        List<VttkManual> list=VttkManual.dao.find("select * from L2C_VTTK");         List<TMSOrderList> list = TMSOrderList.dao.find("select * from TMS_Order_List");         //Excel生成工具         ExcelExport excelExport = new ExcelExport();         String[] listName = {"发运客户"," 订单编号 "," 装货日期","预计送达日期 ","运输类型 ","装货地址","装货联系人",                 "装货联系方式","物料描述 ","装货数量","装货重量 (KG)","装货体积(m3) ","包装规格",                 "到达省份","到达城市 ","收货客户","收货地址","收货联系人 ","收货联系方式",                 "单价","应收运费","附加费用","合计运费","承运商","承运商联系方式 ","承运车辆",                 "驾驶员 ","驾驶员联系方式 ","应付运费","预付运费","回付运费 ","附加费用","附加费单号 ",                 "合同单号","备注"};         Map<Integer, Object> excelMap = excelExport.createTable("列表", listName);                          HSSFCellStyle style = ((HSSFWorkbook) excelMap.get(3)).createCellStyle();           style.setAlignment(HSSFCellStyle.ALIGN_CENTER);                          HSSFRow row = null;         HSSFCell cells = null;         for (int i = 0; i < list.size(); i++){                                row = ((HSSFSheet)excelMap.get(2)).createRow(i + 1);

        cells = row.createCell(0);代表的是当前列数;

        cells.setCellValue(order.getCustomername());代表的是当前列插入的内容;

        cells.setCellStyle(style);代表当前单元格内的样式

下面配置好路径就可以道出了,导出成功之后页面会提示你保存的路径,保存之后就可以查看了,是不是很简单呢
