Spring Boot导入Excel至SQL Server报错，已加依赖配置仍未解决

我尝试用以下Spring Boot代码将Excel数据导入SQL Server，希望通过SQL Server Management Studio（SSMS）进行CRUD操作，但一直遇到相同错误。已经添加了对应依赖和配置属性，问题仍未解决。相关代码如下：

Repository代码 #

public interface AjustageRepository extends JpaRepository<Ajustage, Long> {

    @Query("SELECT v FROM Ajustage v WHERE v.date = (SELECT MAX(v2.date) FROM Ajustage v2)")
    Ajustage lastInput();
}

Service代码 #

@Service
public class ExcelService {

    @Autowired
    private AjustageRepository repository;

    public void processExcelFile(MultipartFile file) {
        try (Workbook workbook = WorkbookFactory.create(file.getInputStream())) {
            Sheet sheet = workbook.getSheetAt(1); // 第二个工作表（索引1）
            int i = 0;
            for (Row row : sheet) {
                i++;
                if(i>1) {
                    Ajustage ajustage = new Ajustage();
                    if (row.getCell(0) != null && row.getCell(0).getCellType() != CellType.BLANK) 
                        break;
                    ajustage.setDate(row.getCell(0).getDateCellValue());
                    ajustage.setLib(row.getCell(1).getStringCellValue());
                    ajustage.setCompte(row.getCell(2).getStringCellValue());
                    ajustage.setNombre(Double.valueOf(row.getCell(3).getNumericCellValue()).longValue());
                    ajustage.setDebit(Double.valueOf(row.getCell(4).getNumericCellValue()).longValue());
                    ajustage.setCredit(Double.valueOf(row.getCell(5).getNumericCellValue()).longValue());
                    System.out.println(ajustage.toString());
                    repository.save(ajustage);
                }
            }
        } catch (IOException e) {
            // 处理Excel文件读取错误
            System.out.println(e.getMessage());
        }
    }
    
    public void insertNewRecord(MultipartFile file) {
        try (Workbook workbook = WorkbookFactory.create(file.getInputStream())) {
            Sheet sheet = workbook.getSheetAt(1); // 第二个工作表（索引1）
            int lastRowNum = this.lastRowNum(sheet);
            Ajustage last = repository.lastInput();
            
            Row row = sheet.getRow(lastRowNum);
            if(last != null) {
                Date toInsert = row.getCell(0).getDateCellValue();
                while(toInsert.after(last.getDate())) {
                    Ajustage ajustage = new Ajustage();
