Java-easy Excel监听器

实现层：

返回成功失败条数，原因

    public String inportExcel(MultipartFile file) {

        ImportExcelListener excelListener = new ImportExcelListener(budgetIssuedService, budgetIssuedRepository, year);
        try {
            EasyExcel.read(multipartFileToFile(file), AnnualBudgetExport.class, excelListener).headRowNumber(5).doReadAll();
        } catch (Exception exception) {
            return "数据格式异常";
        }

        return excelListener.message();
    }

 监听器：

@Data
public class ImportExcelListener extends AnalysisEventListener<AnnualBudgetExport> {
    private final Logger log = LoggerFactory.getLogger(AnnualBudgetExport.class);
    @Autowired
    BudgetIssuedRepository budgetIssuedRepository;
    List<AnnualBudgetExport> list = new ArrayList<>();

    String type = "1";
    int empty = 0;
    int success = 0;
    int error = 0;
    Integer year;

    BudgetIssued
