Question

在上传excel时我遇到了一些问题。

以下是一段代码。

fileStream = new FileInputStream(dirToStore+filename);

        exReader = new ExcelReader(fileStream);
        workbook = exReader.getWorkBook();
        sheet = getDataSheet(workbook, out);
        List rowList = sheet.getAllRows();
        noRows = rowList.size();

        fileStream = new FileInputStream(dirToStore+filename);

        exReader = new ExcelReader(fileStream);
        workbook = exReader.getWorkBook();
        sheet = getDataSheet(workbook, out);
        List rowList = sheet.getAllRows();
        noRows = rowList.size();

int BATCH_SIZE = 1000;
            for (int i = 1; i < noRows; i++) {
                row = (Row) rowList.get(i);

                cellList = row.getAllCells();

                org_Code = ((Cell) cellList.get(0)).getName();
                prod_Family = ((Cell) cellList.get(1)).getName();

error : Index: 7, Size: 7
Exception while reading the excel : Index: 7, Size: 7

在我的 Web 应用程序中上传 excel 时出现上述异常。

请帮我解决上述问题..我不是 java 人:)

你写了

cellList = row.getAllCells();

在这段代码之后，您从cellList对象中获取值

org_Code = ((Cell) cellList.get(0)).getName();

但你之后没有放任何支票

 cellList = row.getAllCells();

当此列表只有 5 个对象并且您尝试执行此操作时，这一行将做什么

item = ((Cell) cellList.get(6)).getName();
item_Revision = ((Cell) cellList.get(7)).getName();

你肯定会得到你提到的例外。
