java - 使用 selenium Web 驱动程序获取 NoClassDefFoundError

Question

尝试在 eclipse 中使用 selenium JUni4 Web 驱动程序打开 excel 文件时出现以下错误。错误和代码如下所示。我是JAVA新手。请帮忙。

public void xlRead_TC(String sPath, int sSheet) throws Exception{   
    //Workbook book = Workbook.createWorkbook(f);       
    System.out.println("Step 1B  - Opening excel files Reached");
    File myxl = new File(sPath);
    FileInputStream myStream = new FileInputStream(myxl);
    //Workbook w;
    //w = Workbook.getWorkbook(myStream);

    XSSFWorkbook myWB = new XSSFWorkbook(myStream);
    //XSSFSheet mySheet = myWB.getSheetAt(sSheet);  // Referring to 1st  sheet

    //xRows_Inp = mySheet.getLastRowNum()+1;
    //xCols_Inp = mySheet.getRow(0).getLastCellNum();
    System.out.println("Rows are " + xRows_Inp);
    System.out.println("Cols are " + xCols_Inp);


    //Workbook[] wbs = new Workbook[] { new HSSFWorkbook(), new XSSFWorkbook() };

    //xRows_TC = mySheet.getLastRowNum()+1;
    //xCols_TC = mySheet.getRow(0).getLastCellNum();
    //System.out.println("Rows are " + xRows_TC);
    //System.out.println("Cols are " + xCols_TC);
    //xData_TC = new String[xRows_TC][xCols_TC];
}

Answer 1

看来您运行的是旧版本的 POI，它仍然需要 dom4j 第三方库。您有两个选择:

1) 升级到 POI 的最新版本，不再需要此库

2) 将 dom4j jar 文件添加到类路径中。 jar 文件是 POI 二进制发行版的一部分。
