XSSFSheet：图表索引超出范围
我正在写POI的xlsx文件的内容，但得到了一个IllegalArgumentException 。
以下是我的代码：
public static void ConvertToCSVOrgtoOrg(String Scenario) throws Exception { String IntermediateXLSXPath=GetFileDetailsSIF(Scenario,"ExcelPath"); String IntermediateCSVPath=GetFileDetailsSIF(Scenario,"CSVPathOrgtoOrg"); File inputFile = new File(IntermediateXLSXPath); File outputFile = new File(IntermediateCSVPath); // For storing data into CSV files StringBuffer data = new StringBuffer(); try { FileOutputStream fos = new FileOutputStream(outputFile); // Get the workbook object for XLSX file XSSFWorkbook wBook = new XSSFWorkbook(new FileInputStream(inputFile)); XSSFFormulaEvaluator.evaluateAllFormulaCells(wBook); // Get first sheet from the workbook XSSFSheet sheet = wBook.getSheetAt(18); XSSFFormulaEvaluator.evaluateAllFormulaCells(wBook); Row row; Cell cell; // Iterate through each rows from first sheet Iterator<Row> rowIterator = sheet.iterator(); while (rowIterator.hasNext()) { row = rowIterator.next(); data.append("\n"); // For each row, iterate through each columns Iterator<Cell> cellIterator = row.cellIterator(); while (cellIterator.hasNext()) { cell = cellIterator.next(); switch (cell.getCellType()) { case Cell.CELL_TYPE_BOOLEAN: data.append(cell.getBooleanCellValue()); break; case Cell.CELL_TYPE_NUMERIC: data.append(cell.getNumericCellValue()); break; case Cell.CELL_TYPE_STRING: data.append(cell.getStringCellValue()); break; case Cell.CELL_TYPE_FORMULA: data.append(cell.getStringCellValue()); case Cell.CELL_TYPE_BLANK: break; default: } } } fos.write(data.toString().getBytes()); Thread.sleep(1000); fos.close(); } catch (Exception ioe) { ioe.printStackTrace(); } }
我得到的例外是：

我有第十八张 任何帮助将不胜感激。
... // Get first sheet from the workbook //XSSFSheet sheet = wBook.getSheetAt(18); Instead, XSSFSheet sheet = wBook.getSheetAt(17); ...
正如你所说的那样你只有18个Excel文件，如果你打算在excel文件中得到第18张表格，你必须从18中减去1。
索引从0开始，而不是从1 。
