1、引包

 <dependency><groupId>cn.afterturn</groupId><artifactId>easypoi-base</artifactId><version>3.0.3</version></dependency><dependency><groupId>cn.afterturn</groupId><artifactId>easypoi-web</artifactId><version>3.0.3</version></dependency><dependency><groupId>cn.afterturn</groupId><artifactId>easypoi-annotation</artifactId><version>3.0.3</version></dependency>

2、导入样例 

 @ApiOperation(notes = "Excel业务导入", value = "Excel业务导入")@PostMapping("/businessFromExcel")public HttpResponse businessFromExcel(@RequestPart("file") MultipartFile file) throws Exception {ImportParams params = new ImportParams();params.setHeadRows(1);List<Business> list = ExcelImportUtil.importExcel(file.getInputStream(),Business.class, params);boolean result = businessService.insertBusiness(list);if(result){return new HttpResponse<>().success();}else{return new HttpResponse<>().error(500, "业务导入失败");}}

3、导出样例

 @ApiOperation(notes = "查询扩缩容导出Excel", value = "查询扩缩容导出Excel")@GetMapping("/resourceToExcel")public Object getScaleResourceToExcel(@RequestParam(name = "resourceType", required = false)  @ApiParam(value = "资源类型") String resourceType,@RequestParam(name = "status", required = false) @ApiParam(value = "状态") Integer status,@RequestParam(name = "startTime", required = false) @DateTimeFormat(pattern="yyyy-MM-dd HH:mm:ss") @ApiParam(value = "开始时间", format = "yyyy-MM-dd HH:mm:ss", example = "2024-01-01 10:10:10") Date startTime,@RequestParam(name = "endTime", required = false) @DateTimeFormat(pattern="yyyy-MM-dd HH:mm:ss") @ApiParam(value = "结束时间", format = "yyyy-MM-dd HH:mm:ss", example = "2024-01-01 10:10:10") Date endTime) throws IOException {List<Scale> list = scaleService.getScaleResourceList(resourceType, status,  startTime, endTime);ExportParams exportParams = new ExportParams();exportParams.setType(ExcelType.XSSF);Workbook workbook = ExcelExportUtil.exportExcel(exportParams, Scale.class, list);ByteArrayOutputStream byteOutputStream  = new ByteArrayOutputStream();workbook.write(byteOutputStream);Map dataBase64 = ImmutableMap.of("filename","扩缩容.xlsx","data", Base64.encodeBase64String(byteOutputStream.toByteArray()));return new HttpResponse<>().success(dataBase64);}
