问题描述

我正在 NetBeans IDE 8.2 中创建 Csv2Xlsx 应用程序，但出现此错误:

I am creating Csv2Xlsx app in NetBeans IDE 8.2 and I got this error:

这是我在项目中的所有依赖项

this is my all Dependencies in project

java 文件中的错误行是这个

error row in java file is this

XSSFSheet sheet = workBook.createSheet("Data"); // com/test/csv2xlsx/Csv2Xlsx.java:[74,38] error: cannot access Date1904Support

但没有红色下划线，尝试编译后给我这个错误

but nothing is underlined by red color, after try to compile give me this error

在我的 Csv2Xlsw java 文件中，我导入了这些命名空间:

in my Csv2Xlsw java file I import these namespaces:

import java.io.FileOutputStream;
import java.io.FileReader;
import java.io.IOException;

import org.apache.log4j.Logger;

import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
import org.apache.poi.xssf.usermodel.XSSFSheet;

这是我的 POM 文件

this is my POM file

我不知道问题出在哪里

public void convert(String sourceCSV, String targetXLSX) throws IOException,
            NumberFormatException {
        try {

            XSSFWorkbook workBook = new XSSFWorkbook();
            XSSFSheet sheet = workBook.createSheet("Data"); // com/test/csv2xlsx/Csv2Xlsx.java:[74,38] error: cannot access Date1904Support
            String currentLine = null;
            int RowNum = 0;
            BufferedReader br = new BufferedReader(new FileReader(sourceCSV));

            while ((currentLine = br.readLine()) != null) {
                String str[] = currentLine.split(delimiter);
                RowNum++;
                Row currentRow = sheet.createRow(RowNum);
                for (int i = 0; i < str.length; i++) {
                    currentRow.createCell(i).setCellValue(str[i]);
                }
            }

            try (FileOutputStream fileOutputStream = new FileOutputStream(targetXLSX)) {
                workBook.write(fileOutputStream);
            }
            System.out.println("Done");
        } catch (IOException | NumberFormatException ex) {
            System.out.println(ex.getMessage() + "Exception in try");
        }
    }

推荐答案

poi 和 poi-ooxml 的版本应该是一样的，这样你就不会再遇到这个问题了.转到您的 pom.xml 以验证版本号并相应地更新它们.

The version of poi and poi-ooxml should be the same and then you won't get this problem anymore. Go to your pom.xml to verify the version number and update them accordingly.
