本文实例为大家分享了SpringBoot使用POI进行Excel下载的具体代码,供大家参考,具体内容如下
使用poi处理Excel特别方便,此处将处理Excel的代码分享出来。
1.maven引用
<dependency> <groupId>org.apache.poi</groupId> <artifactId>poi</artifactId> <version>3.17</version> </dependency>
2.service逻辑代码
/** * 获取下载模版 */ public void salaryTemplate(HttpServletResponse response)throws Exception{ HSSFWorkbook workbook = new HSSFWorkbook(); exportExcel(workbook); response.setHeader("Content-type","application/vnd.ms-excel"); // 解决导出文件名中文乱码 response.setCharacterEncoding("UTF-8"); response.setHeader("Content-Disposition","attachment;filename="+new String("工资模版".getBytes("UTF-8"),"ISO-8859-1")+".xls"); workbook.write(response.getOutputStream()); } //导入为模版 private void exportExcel(HSSFWorkbook workbook) throws Exception { //创建创建sheet HSSFSheet sheet = workbook.createSheet("工资"); //创建单元格样式 CellStyle cellStyle = workbook.createCellStyle(); cellStyle.setFillForegroundColor(HSSFColor.SKY_BLUE.index); //设置首行标题标题 HSSFRow headerRow = sheet.createRow(0); headerRow.createCell(0).setCellStyle(cellStyle); headerRow.createCell(0).setCellValue("工号"); headerRow.createCell(1).setCellStyle(cellStyle); headerRow.createCell(1).setCellValue("姓名"); headerRow.createCell(2).setCellStyle(cellStyle); headerRow.createCell(2).setCellValue("年龄"); //创建三行数据 HSSFRow row; for (int i = 0; i <4; i++) { row = sheet.createRow(i + 1); row.createCell(0).setCellStyle(cellStyle); row.createCell(0).setCellValue(i); row.createCell(1).setCellStyle(cellStyle); row.createCell(1).setCellValue("张三"); row.createCell(2).setCellStyle(cellStyle); row.createCell(2).setCellValue(19); } }
3.controller
@GetMapping("/salary/template") public void salaryTemplate(HttpServletResponse response)throws Exception{ salaryService.salaryTemplate(response); }
