Excel导出这里不讲,方法很多,原生的POI可以参照 Java原生POI实现的Excel导入导出(简单易懂)
这里只说怎么给Excel每一列设置不同的样式,好比下面如许的

直接上代码
- @Override
- public void exportTemplate(HttpServletRequest request, HttpServletResponse response) throws Exception {
- try (Workbook wb = new SXSSFWorkbook(1000)) {
- // 构建一个导出页
- Sheet sheet = wb.createSheet("用户信息表");
- CellStyle style = wb.createCellStyle();
- style.setAlignment(HorizontalAlignment.CENTER);
- style.setVerticalAlignment(VerticalAlignment.CENTER);
- style.setBorderBottom(BorderStyle.THIN);
- style.setBorderLeft(BorderStyle.THIN);
- style.setBorderTop(BorderStyle.THIN);
- style.setBorderRight(BorderStyle.THIN);
- style.setWrapText(true);// 自动换行
- Font font = wb.createFont();
- font.setFontName("宋体");
- font.setFontHeightInPoints((short) 11);
- style.setFont(font);
- DataFormat format = wb.createDataFormat();
- style.setDataFormat(format.getFormat("@")); // 设置为文本格式
- sheet.setDefaultRowHeight((short) 500);
- // 构建excel抬头
- Row row0 = sheet.createRow((int) 0); // 第一行
- Cell cell0_0 = row0.createCell(0);
- cell0_0.setCellValue("序号");
- cell0_0.setCellStyle(style);
- sheet.setColumnWidth(0, 15 * 256);// 列宽
- sheet.setDefaultColumnStyle(0, style);
- Cell cell0_1 = row0.createCell(1);
- cell0_1.setCellValue("姓名");
- cell0_1.setCellStyle(style);
- sheet.setColumnWidth(1, 15 * 256);// 列宽
- sheet.setDefaultColumnStyle(1, style);
- Cell cell0_2 = row0.createCell(2);
- cell0_2.setCellValue("国家标识码");
- cell0_2.setCellStyle(style);
- sheet.setColumnWidth(2, 15 * 256);// 列宽
- sheet.setDefaultColumnStyle(2, style);
- Cell cell0_3 = row0.createCell(3);
- cell0_3.setCellValue("手机号");
- cell0_3.setCellStyle(style);
- sheet.setColumnWidth(3, 15 * 256);// 列宽
- sheet.setDefaultColumnStyle(3, style);
- Cell cell0_4 = row0.createCell(4);
- cell0_4.setCellValue("身份证号");
- cell0_4.setCellStyle(style);
- sheet.setColumnWidth(4, 20 * 256);// 列宽
- sheet.setDefaultColumnStyle(4, style);
- Cell cell0_5 = row0.createCell(5);
- cell0_5.setCellValue("部门名称(选填)");
- cell0_5.setCellStyle(style);
- sheet.setColumnWidth(5, 20 * 256);// 列宽
- sheet.setDefaultColumnStyle(5, style);
- Cell cell0_6 = row0.createCell(6);
- cell0_6.setCellValue("职位(选填,多个用英文/分隔)");
- cell0_6.setCellStyle(style);
- sheet.setColumnWidth(6, 35 * 256);// 列宽
- sheet.setDefaultColumnStyle(6, style);
- // 构建示例
- Row row1 = sheet.createRow((int) 1); // 第二行
- CellStyle style1 = wb.createCellStyle();
- style1.setAlignment(HorizontalAlignment.CENTER);
- style1.setVerticalAlignment(VerticalAlignment.CENTER);
- style1.setBorderBottom(BorderStyle.THIN);
- style1.setBorderLeft(BorderStyle.THIN);
- style1.setBorderTop(BorderStyle.THIN);
- style1.setBorderRight(BorderStyle.THIN);
- style1.setWrapText(true);// 自动换行
- style1.setFont(font);
- DataFormat format1 = wb.createDataFormat();
- style1.setDataFormat(format1.getFormat("@")); // 设置为文本格式
- style1.setFillForegroundColor((short) 13);// 设置背景色
- style1.setFillPattern(FillPatternType.SOLID_FOREGROUND);
- Cell cell1_0 = row1.createCell(0);
- cell1_0.setCellValue("示例(保留)");
- cell1_0.setCellStyle(style1);
- Cell cell1_1 = row1.createCell(1);
- cell1_1.setCellValue("张三");
- cell1_1.setCellStyle(style1);
- Cell cell1_2 = row1.createCell(2);
- cell1_2.setCellValue("+86");
- cell1_2.setCellStyle(style1);
- Cell cell1_3 = row1.createCell(3);
- cell1_3.setCellValue("13700002222");
- cell1_3.setCellStyle(style1);
- Cell cell1_4 = row1.createCell(4);
- cell1_4.setCellValue("452186200001010001");
- cell1_4.setCellStyle(style1);
- Cell cell1_5 = row1.createCell(5);
- cell1_5.setCellValue("技术部");
- cell1_5.setCellStyle(style1);
- Cell cell1_6 = row1.createCell(6);
- cell1_6.setCellValue("科室主任/细胞生物学家/博士生导师");
- cell1_6.setCellStyle(style1);
- // 构建第二列
- Row row2 = sheet.createRow((int) 2); // 第一行
- Cell cell2_0 = row2.createCell(0);
- cell2_0.setCellValue("1");
- cell2_0.setCellStyle(style);
- Cell cell2_1 = row2.createCell(1);
- cell2_1.setCellValue("");
- cell2_1.setCellStyle(style);
- Cell cell2_2 = row2.createCell(2);
- cell2_2.setCellValue("");
- cell2_2.setCellStyle(style);
- Cell cell2_3 = row2.createCell(3);
- cell2_3.setCellValue("");
- cell2_3.setCellStyle(style);
- Cell cell2_4 = row2.createCell(4);
- cell2_4.setCellValue("");
- cell2_4.setCellStyle(style);
- Cell cell2_5 = row2.createCell(5);
- cell2_5.setCellValue("");
- cell2_5.setCellStyle(style);
- Cell cell2_6 = row2.createCell(6);
- cell2_6.setCellValue("");
- cell2_6.setCellStyle(style);
- String fileName = "用户信息表.xlsx";
- if (request.getHeader("User-Agent").toLowerCase().indexOf("firefox") > 0) {
- fileName = new String(fileName.getBytes("UTF-8"), "ISO8859-1"); // firefox浏览器
- } else if (request.getHeader("User-Agent").toUpperCase().indexOf("MSIE") > 0) {
- fileName = URLEncoder.encode(fileName, "UTF-8");// IE浏览器
- } else if (request.getHeader("User-Agent").toUpperCase().indexOf("CHROME") > 0) {
- fileName = new String(fileName.getBytes("UTF-8"), "ISO8859-1");// 谷歌
- }
- response.reset();
- response.setContentType("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
- response.setHeader("Content-Disposition", "attachment; filename=" + fileName);
- wb.write(response.getOutputStream());
- response.getOutputStream().close();
- }
- }
