导入

@Autowize
private CsvContext csvContext;
public BaseDataAPI upload(HttpServletRequest request,
                                        @RequestParam("file") MultipartFile file){
try {
            if(file==null){
                return D.error("请上传文件");
            }
           CsvImportRequest ir=new CsvImportRequest.Builder().setErrorFilter(filterError).setFile(file)
                    .setId("upload-1").build();
            //解析模板内容,对比模板内容是否和上传的一样
            CsvImportResponse response= csvContext.transfer(ir);
            return D.ok(response.getList());
        } catch (CsvImportException e) {
            return D.error(e.getMessage());
        } catch (Exception e) {
            return D.error(e.getMessage());
        }
 }

导出

@Autowize
private CsvContext csvContext;
public BaseDataAPI export(){

         、try {
                fileName = new String(fileName.getBytes(), "ISO8859-1");
            } catch (UnsupportedEncodingException var3) {
                var3.printStackTrace();
            }
            response.setContentType(MediaType.APPLICATION_OCTET_STREAM.toString());

            response.addHeader("Pargam", "no-cache");
            response.addHeader("Cache-Control", "no-cache");
            FileCopyUtils.copy(csvContext.export(id,data), response.getOutputStream());
        } catch (Exception var4) {
            var4.printStackTrace();
