java实现excel自定义样式与字段导出详细图文教程

更新时间：2023年09月26日 11:04:03 作者：qq_40415205

最近接到一个需求,客户不满意原本导出的csv文件,想要导出Excel文件,下面这篇文章主要给大家介绍了关于java实现excel自定义样式与字段导出详细图文教程

前言

java 功能中，有一个功能是大家经常做的，就是excel导出，简单的excel导出可以直接用阿里的easyExcel添加注解自动导出来某些固定字段就行了，这个是比较简单的导出，本文就不作过多赘述这篇文章主要是针对，某些页面的导出，比如说按照页面上的表格的样式导出数据类似于下面图片这样的，主要应用于报表，自定义的样式之类的excel导出本文导出总汇，标品，定开三个sheet的数据，有则导出，无则不用导出导出的excel需要的pom结构

最后导出的请求接口字段

最后导出的内容如下

    <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>easyexcel</artifactId>
            <version>3.2.1</version>
        </dependency>
        <dependency>
            <groupId>org.apache.poi</groupId>
            <artifactId>ooxml-schemas</artifactId>
            <version>1.4</version>
        </dependency>

1、第一步控制层

    /**
     * 根据报价单id导出报表
     *
     * @param response
     * @param id
     */
    @PostMapping("/exportPriceDetail/{id}")
    @ApiOperation(value = "根据报价单id导出报表")
    @SneakyThrows
    public void exportPriceDetail(HttpServletResponse response, @PathVariable("id") Long id, @RequestBody List<ExportMenuReq> menus) {
        response.setContentType("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
        response.setCharacterEncoding("utf-8");
        String encodeFileName = URLEncoder.encode("报价单", "UTF-8").replaceAll("\\+", "%20");
        response.setHeader("Content-disposition", "attachment;filename*=utf-8''" + encodeFileName + ".xlsx");
        response.setHeader("Access-Control-Expose-Headers", "Content-Disposition");
        priceDetailExportService.exportPriceDetail(response, id,menus);
    }

2、第二步逻辑层

主要生成水印和处理要导出的，模块的逻辑

    @SneakyThrows
    public void exportPriceDetail(HttpServletResponse response, Long id, List<ExportMenuReq> menus) {
        UserDTO user = AuthenticationContext.getUser();
        Watermark watermark = new Watermark();
        watermark.setContent(user.getUserAccount()+"@XX集团"+user.getErpId());
        watermark.setWidth(500);
        watermark.setHeight(200);
        watermark.setYAxis(200);
        ExcelWriter excelWriter = EasyExcel.write(response.getOutputStream()).inMemory(true).registerWriteHandler(new CustomerWaterMarkHandler(watermark)).build();
        List<String> sheetNames = new ArrayList<>();
        Map<String, List<String>> openContentColumnNames = new HashMap<>();
        Map<String, List<String>> openContentDevelopmentColumnNames = new HashMap<>();
        for (ExportMenuReq menu : menus) {
            sheetNames.add(menu.getName());
            if (CollectionUtils.isNotEmpty(menu.getChildren())) {
                List<String> columnNames = openContentColumnNames.get(menu.getName()) != null ? openContentColumnNames.get(menu.getName()) : new ArrayList<String>();
                List<ExportMenuReq> openContents = menu.getChildren();
                for (ExportMenuReq openContent : openContents) {
                    if (Constants.DEVELOPMENT_INFO.equals(openContent.getName()) && CollectionUtils.isNotEmpty(openContent.getChildren())) {
                        List<ExportMenuReq> developmentColumns = openContent.getChildren();
                        List<String> developmentColumnNames = developmentColumns.stream().map(tree -> tree.getName() + Constants.DEVELOPMENT_SUFFIX).collect(Collectors.toList());
                        columnNames.addAll(developmentColumnNames);
                        openContentDevelopmentColumnNames.put(menu.getName(), developmentColumnNames);
                    } else {
                        columnNames.add(openContent.getName());
                    }
                }
                //根据ID获取列，如果用名称遇到名称一样的数据，就会因为key一样导致只有一个列表，并且两个列表value都放入一个key
                openContentColumnNames.put(menu.getId().toString(), columnNames);
            }
        }
        exportPriceDetail(id, sheetNames, openContentColumnNames, openContentDevelopmentColumnNames, excelWriter);
    }

2.1：writeCollectInfo（）方法，组装总汇的导出数据

 private void writeCollectInfo(CollectInfoVo collectInfoVo, ExcelWriter excelWriter) {
        if (collectInfoVo == null) {
            return;
        }
        WriteSheet writeSheet = EasyExcel.writerSheet("总汇").build();
        int tableNo = 0;
        Integer headSize = 9;
        //有效期
        String priceDataInfo = getPriceDataInfo(collectInfoVo.getPriceData(), collectInfoVo.getExpirationDay());
        ContactInfoExcelVO priceDataInfoVO = ContactInfoExcelVO.builder()
                .contactInfo(priceDataInfo)
                .build();
        WriteTable priceDataInfoTable = EasyExcel.writerTable().tableNo(tableNo++).needHead(Boolean.FALSE).registerWriteHandler(new ColumnMergeStrategy(0, headSize - 1)).head(ContactInfoExcelVO.class).build();
        excelWriter.write(Arrays.asList(priceDataInfoVO), writeSheet, priceDataInfoTable);
        //标题
        Map<String, String> params = new HashMap<>();
        String priceName = StringUtils.isNotBlank(collectInfoVo.getPriceName()) ? collectInfoVo.getPriceName() : "报价单";
        params.put("priceName", priceName);
        WriteTable priceNameTable = EasyExcel.writerTable().tableNo(tableNo++).needHead(Boolean.TRUE).registerWriteHandler(new HeadWriteHandler(params)).head(PriceBillBaseExcelVO.class).build();
        excelWriter.write(Collections.emptyList(), writeSheet, priceNameTable);
        //联系人信息
        String contactInfo = String.format("联系人: %s\r\n联系方式: %s", StringUtils.trimToEmpty(collectInfoVo.getContactName()), StringUtils.trimToEmpty(collectInfoVo.getMobile()));
        ContactInfoExcelVO contactInfoExcelVO = ContactInfoExcelVO.builder()
                .contactInfo(contactInfo)
                .build();
        WriteTable contactInfoTable = EasyExcel.writerTable().tableNo(tableNo++).needHead(Boolean.FALSE).registerWriteHandler(new ColumnMergeStrategy(0, headSize - 1)).head(ContactInfoExcelVO.class).build();
        excelWriter.write(Arrays.asList(contactInfoExcelVO), writeSheet, contactInfoTable);
        //最后三列显示小计
        Integer lastCol = headSize - 5;
        //标品
        StandardInfoVO standardInfo = collectInfoVo.getStandardInfo();
        if (standardInfo != null && CollectionUtils.isNotEmpty(standardInfo.getStandards())) {
            List<StandardVO> standards = standardInfo.getStandards();
            List<StandardExcelVO> standardExcelVOS = standards.stream().map(standInfoConverter::toExcel).collect(Collectors.toList());
            standardExcelVOS.stream().forEach(standard -> {
                // 设置功能清单
                if (StringUtils.isNotBlank(standard.getProductListUrl())) {
                    WriteCellData<String> hyperlink = new WriteCellData<>("点击查看");
                    HyperlinkData hyperlinkData = new HyperlinkData();

            //小计

            writeSubtotal(excelWriter, writeSheet, standardInfo.getTaxPrice(), standardInfo.getTaxUpperPrice(), standardInfo.getNotTaxTotalPrice(), standardInfo.getNotTaxTotalUpperPrice(), lastCol, tableNo++);
        }
        //第三方产品
        TripartiteCollectVO priceTripartiteInfo = collectInfoVo.getPriceTripartiteInfo();

2.1导出的表格模块比较多，所以实体类也比较多，本文就举一个对象标品和培训服务的例子，其他实体类类似

                .build();
        excelWriter.write(Arrays.asList(notTaxTotal, taxTotal), writeSheet, totalTable);
    }

2.3：写入总合计

private void writeSummaryTotal(ExcelWriter excelWriter, WriteSheet writeSheet, CollectInfoVo collectInfoVo, BigDecimal summaryPrice, String upperSummaryPrice, Integer tableNo) {
        BigDecimal totalNotTaxPrice = collectInfoVo.getNotTaxTotalPrice() != null ? new BigDecimal(collectInfoVo.getNotTaxTotalPrice()) : new BigDecimal("0");
        String notTaxPrice = String.format("%.2f",totalNotTaxPrice.divide(new BigDecimal(100), 2, BigDecimal.ROUND_HALF_UP));
        //不含税价
        SummaryExcelVO notTaxSummary = SummaryExcelVO.builder()
                .priceDetail("报价单描述:" + StringUtils.trimToEmpty(collectInfoVo.getPriceDetail()))
                .type("总合计:")
                .priceType("不含税价")
                .totalPriceStr("￥"+notTaxPrice)
                .upperTotalPriceStr(collectInfoVo.getNotTaxTotalUpperPrice())
                .build();
        //含税价
        String priceStr = String.format("%.2f",summaryPrice.divide(new BigDecimal(100), 2, BigDecimal.ROUND_HALF_UP));
        SummaryExcelVO taxSummary = SummaryExcelVO.builder()

        WriteTable totalTable = EasyExcel.writerTable()
                .needHead(Boolean.FALSE)
                .head(SummaryExcelVO.class)
                .tableNo(tableNo)

                .registerWriteHandler(new SubtotalMergeStrategy(tableMergeProperties))
                .build();
        excelWriter.write(Arrays.asList(notTaxSummary, taxSummary), writeSheet, totalTable);
    }

3、导出标品的sheet

 
    /**
     * 导出标品内容
     *
     * @param standardInfo
     * @param excelWriter
     */
    private void writeStandardDetail(StandardInfoVO standardInfo, ExcelWriter excelWriter) {
        if (standardInfo != null && CollectionUtils.isNotEmpty(standardInfo.getStandards())) {
            WriteSheet writeSheet = EasyExcel.writerSheet("标品").build();
            int tableNo = 0;
            if (!standardInfo.getIsExport()) {
                //有效期
                String priceDataInfo = getPriceDataInfo(standardInfo.getPriceData(), standardInfo.getExpirationDay());
                ContactInfoExcelVO priceDataInfoVO = ContactInfoExcelVO.builder()
                        .contactInfo(priceDataInfo)
                        .build();
                WriteTable priceDataInfoTable = EasyExcel.writerTable().tableNo(tableNo++).needHead(Boolean.FALSE).registerWriteHandler(new ColumnMergeStrategy(0, 6)).head(ContactInfoExcelVO.class).build();
                excelWriter.write(Arrays.asList(priceDataInfoVO), writeSheet, priceDataInfoTable);
            }
            List<StandardDetailExcelVO> standardDetailExcelVOS = standardInfo.getStandards().stream()
                    .map(standInfoConverter::toDetailExcel).collect(Collectors.toList());
            standardDetailExcelVOS.stream().forEach(standardDetailExcelVO -> {
                // 设置功能清单
                if (StringUtils.isNotBlank(standardDetailExcelVO.getProductListUrl())) {
                    WriteCellData<String> hyperlink = new WriteCellData<>("点击查看");
                    standardDetailExcelVO.setProductListUrlHyperlink(hyperlink);
                    HyperlinkData hyperlinkData = new HyperlinkData();
                    hyperlink.setHyperlinkData(hyperlinkData);
                    hyperlinkData.setAddress(standardDetailExcelVO.getProductListUrl());
                    hyperlinkData.setHyperlinkType(HyperlinkData.HyperlinkType.URL);
                }
            });
            WriteTable writeTable = EasyExcel.writerTable().tableNo(tableNo++).needHead(Boolean.TRUE).head(StandardDetailExcelVO.class).build();
            excelWriter.write(standardDetailExcelVOS, writeSheet, writeTable);
            //    总计
            //StandardDetailExcelVO total = new StandardDetailExcelVO();
            //total.setProductName("总计:");
            //total.setCurrentTotalPrice(standardInfo.getStandardTotalPrice());
            //writeTotal(excelWriter, writeSheet, total, tableNo++, 0, 3);
            //writeStandardSubtotal(excelWriter,writeSheet,standardInfo.getStandardTotalPrice(),standardInfo.getStandardTotalUpperPrice(),tableNo++);
            writeSubtotal(excelWriter, writeSheet, standardInfo.getTaxPrice(), standardInfo.getTaxUpperPrice(), standardInfo.getNotTaxTotalPrice(), standardInfo.getNotTaxTotalUpperPrice(), 4, tableNo++);
        }
    }

4、导出定开的内容

@SneakyThrows
    private void writeDynamicOpeningInfos(OpeningInfoVO openingVO, CollectBaseVo baseVo, List<String> columnNames, List<String> developmentColumnNames, ExcelWriter excelWriter) {
        List<ModuleInfoVo> moduleInfos = openingVO.getModuleInfos();
        if (CollectionUtils.isNotEmpty(moduleInfos)) {
            //查询动态表头格式
            PriceOpenContentExcel priceOpenContentExcel = iPriceOpenContentExcelService.selectByPriceOpenId(openingVO.getId());
            List<OpenDetailDevelopmentResult> openDetailDevelopmentResults = JSON.parseArray(priceOpenContentExcel.getDynamicHead(), OpenDetailDevelopmentResult.class);
            //根据动态表头动态生成class
            Map<String, String> params = new HashMap<>();
            Class<? extends OpeningDetailExcelVo> openingDetailExcelVoClazz = assembleTemplateClass(openDetailDevelopmentResults, params);
            List<OpeningDetailExcelVo> openingDetailExcelVos = moduleInfos.stream().map(openingConverter::toDetailExcel).collect(Collectors.toList());
            List<? extends OpeningDetailExcelVo> detailExcelVos = BeanUtil.copyToList(openingDetailExcelVos, openingDetailExcelVoClazz);
            assembleDynamicFieldsAndCalculateTotal(detailExcelVos, openingDetailExcelVoClazz);
            //获取排除的列
            List<Field> excludeColumnField = getExcludeColumnFields(openingDetailExcelVoClazz, columnNames);
            //获取合并单元格并根据排除列重新计算合并单元格坐标
            ExcelMergeStrategy excelMergeStrategy = calculateMergeProperty(priceOpenContentExcel, excludeColumnField);
            List<String> excludeColumnFieldNames = excludeColumnField.stream().map(Field::getName).collect(Collectors.toList());
            WriteSheet writeSheet = EasyExcel.writerSheet(openingVO.getOpeningName()).registerWriteHandler(new HeadWriteHandler(params)).excludeColumnFieldNames(excludeColumnFieldNames).head(openingDetailExcelVoClazz).build();
            int tableNo = 0;
            WriteTable writeTable = EasyExcel.writerTable().tableNo(tableNo++).needHead(Boolean.FALSE).registerWriteHandler(excelMergeStrategy).build();
            excelWriter.write(detailExcelVos, writeSheet, writeTable);
            //总列数-研发项列数-备注一列
            //Integer lastCol = CollectionUtils.size(columnNames) - CollectionUtils.size(developmentColumnNames) - (excludeColumnFieldNames.contains("remark")?0:1) - 1;
            if (CollectionUtils.size(columnNames) - 4 >= 0) {
                //小计
                writeDynamicHeadSubtotal(excelWriter, writeSheet, baseVo, CollectionUtils.size(columnNames), CollectionUtils.size(columnNames) - 4, tableNo++);
            }
        }
    }

4.1：导出定开的小计

private void writeDynamicHeadSubtotal(ExcelWriter excelWriter, WriteSheet writeSheet, CollectBaseVo baseVo, Integer headSize, Integer lastCol, Integer tableNo) {
        Long taxPrice = baseVo.getTaxPrice();
        String taxPriceStr = String.format("%.2f",new BigDecimal(taxPrice).divide(new BigDecimal(100), 2, BigDecimal.ROUND_HALF_UP));
        Long notTaxTotalPrice = baseVo.getNotTaxTotalPrice();
        String notTaxTotalPriceStr = String.format("%.2f",new BigDecimal(notTaxTotalPrice).divide(new BigDecimal(100), 2, BigDecimal.ROUND_HALF_UP));
        List<List<String>> headList = ListUtils.newArrayList();
        List<String> head = ListUtils.newArrayList();
        for (int i = 0; i <= lastCol; i++) {
            head.add("小计:");
        }
        head.add("金额类型");
        head.add("金额");
        head.add("大写金额");
        headList.add(head);
        List<List<String>> dataList = ListUtils.newArrayList();
        List<String> notTaxTotal = ListUtils.newArrayList();
        for (int i = 0; i <= lastCol; i++) {
            notTaxTotal.add("小计:");
        }
        notTaxTotal.add("不含税价");
        notTaxTotal.add("￥"+notTaxTotalPriceStr);
        notTaxTotal.add(baseVo.getNotTaxTotalUpperPrice());
        dataList.add(notTaxTotal);
        List<String> taxTotal = ListUtils.newArrayList();
        for (int i = 0; i <= lastCol; i++) {
            taxTotal.add("小计:");
        }
        taxTotal.add("含税价");
        taxTotal.add("￥"+taxPriceStr);
        taxTotal.add(baseVo.getTaxUpperPrice());
        dataList.add(taxTotal);
        TableMergeProperty tableMergeProperty = new TableMergeProperty(0, 1, 0, lastCol);
        SubtotalRepeatMergeStrategy subtotalRepeatMergeStrategy = new SubtotalRepeatMergeStrategy(Arrays.asList(tableMergeProperty));
        WriteTable totalTable = EasyExcel.writerTable()
                .needHead(Boolean.FALSE)
                .head(headList)
                .tableNo(tableNo)
                .registerWriteHandler(new SimpleRowHeightStyleStrategy((short) 33, (short) 30))
                .registerWriteHandler(subtotalRepeatMergeStrategy)
                .registerWriteHandler(new SubtotalCellStyleStrategy())
                .build();
        excelWriter.write(dataList, writeSheet, totalTable);
        subtotalRepeatMergeStrategy.setFirstRow();
    }

至此，导出内容完毕
