java 实现 excel 自定义样式和字段导出

冷不防 2024-03-17 14:18 15阅读 0赞

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>

                <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 -> {

                    if (StringUtils.isNotBlank(standard.getProductListUrl())) {

                    }

                WriteTable standardTable = EasyExcel.writerTable().tableNo(tableNo++).needHead(Boolean.TRUE).head(StandardExcelVO.class).build();
                excelWriter.write(standardExcelVOS, writeSheet, standardTable);
                //小计
                //最后三列显示小计
                writeSubtotal(excelWriter, writeSheet, standardInfo.getTaxPrice(), standardInfo.getTaxUpperPrice(), standardInfo.getNotTaxTotalPrice(), standardInfo.getNotTaxTotalUpperPrice(), lastCol, tableNo++);

                    true);
            writeSummaryTotal(excelWriter, writeSheet, collectInfoVo, totalDiscountPrice, totalUpperDiscountPrice, tableNo++);
        }

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
