我正在使用Aspose Cell Api从Excel工作表中查找和替换值。 我正在使用文本文件来定义每个变量的替换

Question

我正在使用java执行此操作。请帮助我。我在测试文件中定义了变量，并且我正在使用文本文件进行替换，但未执行。请在此帮助我。在以下代码中出现ArrayIndexOutOfBound错误。 导入com.aspose.cells。*;

    import java.io.*;

Answer 1

请参见以下示例代码。 和你一样 我已经使用示例Excel文件测试了代码，并成功生成了输出Excel文件，没有任何错误。

我已经附上了显示三件事的屏幕截图

1. Test.xlsx
2. Output.xlsx
3. Demo.txt

这些示例文件是我创建的，用于测试您的代码。 如您在图像中看到的，根据Demo.txt，Output.xlsx文件是正确的。

这是示例可运行代码，与您的代码相同，只是稍作修改以供参考。

Java的

Workbook workbook = new Workbook(dirPath + "test.xlsx");

Worksheet worksheet = workbook.getWorksheets().get(0);

// Specify the range where you want to search
// Here the range is E3:H6
CellArea area = CellArea.createCellArea("A1", "A20");

// Specify Find options
FindOptions opts = new FindOptions();
opts.setLookInType(LookInType.VALUES);
opts.setLookAtType(LookAtType.ENTIRE_CONTENT);
opts.setRange(area);

//////////////////////////

Reader reader = null;

try {
    reader = new InputStreamReader(new FileInputStream(dirPath + "demo.txt"));
} catch (FileNotFoundException e1) {
    e1.printStackTrace();
}
BufferedReader bufferedReader = new BufferedReader(reader);
List<String> lines = new ArrayList<String>();
String line = null;

try {
    while ((line = bufferedReader.readLine()) != null) {
        lines.add(line);
    }
} catch (IOException e1) {
    e1.printStackTrace();
}

////////////////////////

Cell cell = null;

for (int i = 0; i < lines.size(); i++) {
    String[] splitting = lines.get(i).split("\t");

    String array1[] = new String[100];
    String array2[] = new String[100];
    array1[i] = splitting[0];
    array2[i] = splitting[1];

    System.out.println(array1[i] + "\t" + array2[i]);

    for (int j = 0; j < 20; j++) {

        cell = worksheet.getCells().find(array1[i], cell, opts);

        // If no such cell found, then break the loop
        if (cell == null)
            break;

        // Replace the cell with value replace
        cell.putValue(array2[i]);

    }

}

// Save the workbook
workbook.save(dirPath + "Output.xlsx");
System.out.println("Success");
