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");
            }
           
            //解析模板内容，对比模板内容是否和上传的同样外层须要抓取异常由于错误信息是以异常来进行鉴别
            List<Map<String,Object>> list= csvContext.transfer(file,"throng-"+uploadType,product);
            
            return D.ok(hash);
        } 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.setHeader("Content-Disposition", "attachment;filename=" + fileName);
            response.addHeader("Pargam", "no-cache");
            response.addHeader("Cache-Control", "no-cache");
            FileCopyUtils.copy(csvContext.export(id,data), response.getOutputStream());
        } catch (Exception var4) {
            var4.printStackTrace();
