Jaspersofter Studio

如上图 ,表中需要的字段要在Fields里面进行新增配置

进行关联,其中Fields里的List是代码里的数组名字

Fields里定义的字段都要在对象里面定义,并赋值,才可以被插入报表.

引入依赖

jasperReport导出实现:

      eos.setDetailsList(new JRBeanCollectionDataSource(maps, false));
            orderList.add(eos);
            JasperPrint enquiryNoPrint = JasperFillManager.fillReport(enquiryRef, parameters, new JRBeanCollectionDataSource(orderList, false));
            printList.add(enquiryNoPrint);

            JRPdfExporter exporter = new JRPdfExporter();
            exporter.setExporterInput(SimpleExporterInput.getInstance(printList));
            exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(outputStream));
            exporter.exportReport();

具体实现方法

public void exportOrderPdf(Long id, BaseUserEntity user, ServletOutputStream outputStream) throws IOException, JRException {
        //报表结果集查询
        NewPurchaseOrderModel result = newPurchaseOrderService.purchaseOrderDetail(user, id);
        List details = result.getPurOrderDetailsList();
        PurOrder order = result.getOrders();
        List printList = new ArrayList<>();
        Map parameters = new HashMap<>(16);

        try (InputStream enquiryRef = resourceLoader.getResource("classpath:report/enquiry_order.jasper").getInputStream()) {

            List> maps = new ArrayList<>();
            List> mapTaxed = new ArrayList<>();
            EnquiryOrderSource eos = new EnquiryOrderSource();
            eos.setEnquiryNo(order.getOrderNo());
            Date createDate = order.getCreateDate();
            eos.setCreateDate(format.format(createDate));

            Map mapTax = new HashMap<>();
            mapTax.put("untaxedAmount",changeF2Y(order.getUntaxedAmount()));
            mapTax.put("totalAmount",changeF2Y(order.getTotalAmount()));
            eos.setTotalData(new JRBeanCollectionDataSource(mapTaxed, false));

            List orderList = new ArrayList<>();
            for (OrderRequestDetailsModel detail : details) {
                Map map = new HashMap<>();
                map.put("materialsCode", detail.getMaterialsCode() == null ? "" : detail.getMaterialsCode());
                map.put("materialsName", detail.getMaterialsName() == null ? "" : detail.getMaterialsName());
                map.put("planDate", detail.getPlanDate() == null ? "" : format.format(detail.getPlanDate()));
                map.put("materialsPrice", detail.getMaterialsPrice() == null ? "" : changeF2Y(detail.getMaterialsPrice()));
                map.put("totalAmount", detail.getTotalAmount() == null ? "" : changeF2Y(detail.getTotalAmount()));
                maps.add(map);
            }
            eos.setDetailsList(new JRBeanCollectionDataSource(maps, false));
            orderList.add(eos);
            JasperPrint enquiryNoPrint = JasperFillManager.fillReport(enquiryRef, parameters, new JRBeanCollectionDataSource(orderList, false));
            printList.add(enquiryNoPrint);

            JRPdfExporter exporter = new JRPdfExporter();
            exporter.setExporterInput(SimpleExporterInput.getInstance(printList));
            exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(outputStream));
            exporter.exportReport();
        }

    }
