带有外部工作簿的单元格公式参考HSSFWorkbook

问题描述

我正在编写一种工具来简化Excel的某些电子表格工作。我有需要以前文件的Excel文件。我有一些单元格具有引用其他工作簿的公式。例如：PERIOD 2.xls需要PERIOD 1.xls。据我了解，这意味着我需要添加此参考并对其进行评估。下面是我的代码片段，展示了我如何做这一切：

public PeriodFileWriter(File currentPeriodFile) throws IOException,InvalidFormatException {
    Files.copy(templateFile.toPath(),currentPeriodFile.toPath(),StandardcopyOption.REPLACE_EXISTING);
    referencedFiles = new HashMap<>();
    loadCurrentWorkbook(currentPeriodFile);
    loadPrevIoUsWorkbook();
  }
    
  private void loadCurrentWorkbook(File currentPeriodFile) throws IOException {
    this.currentPeriodFile = currentPeriodFile;
    this.currInputStream = new FileInputStream(currentPeriodFile);
    this.currWorkbook =  new hssfWorkbook(currInputStream);
    this.currEvaluator = currWorkbook.getCreationHelper().createFormulaEvaluator();
    referencedFiles.put(currentPeriodFile.getName(),currEvaluator);
  }
  
  private void loadPrevIoUsWorkbook() throws IOException {
    String prevFilePath = templateFile.getParent() + "\\" + getPrevIoUsFilename();
    prevIoUsPeriodFile = new File(prevFilePath);
    prevInputStream =  new FileInputStream(prevIoUsPeriodFile);
    prevWorkbook = new hssfWorkbook(prevInputStream);
    prevEvaluator = prevWorkbook.getCreationHelper().createFormulaEvaluator();
    referencedFiles.put(getPrevIoUsFilename(),prevEvaluator);
    currEvaluator.setupReferencedWorkbooks(referencedFiles);
    currEvaluator.evaluateall();
  }

  public void updateYTDBudget(String sheetName) {
    String prevFileName = getPrevIoUsFilename();
    String cellFormula = String.format("'[%s]%s'!%s + E56",prevFileName,sheetName,"H56");
    Sheet sheet = getWorkbook().getSheet(sheetName);
    ExcelUtil.setCellFormula(sheet,"H56",cellFormula);
  }

但是，当我运行代码时，我得到了：
