我做了一个脚本来读取excel文件，它是没有问题的IDEA IDK或cmd上运行的java -jar script.jar。

然而，当我使用exe4j来传输EXE文件时，它会报告如下错误：

D1.excel是要读取的文件。excel代码如下所示：

@SuppressWarnings("resource")
    public static void readDataSet(String filePath){
        InputStream in;
        DataFormatter formatter = new DataFormatter();
        try{
            Excel_Util eu = new Excel_Util();
            ClassLoader cl = eu.getClass().getClassLoader();
             in = cl.getResourceAsStream("D1.xlsx");

            //input = new FileInputStream(filePath);
            XSSFWorkbook book = new XSSFWorkbook(in);
            XSSFSheet sheet = book.getSheetAt(0);
            XSSFRow row;
            for(int i=sheet.getFirstRowNum()+1;i<sheet.getPhysicalNumberOfRows();++i){
                row = sheet.getRow(i);
                Scheme_No_Column.add(row.getCell(0).getStringCellValue());
                Pv_Capacity_Column.add(row.getCell(1).getStringCellValue());
                Device_No_Column.add(row.getCell(2).getStringCellValue());
                Power_Column.add(formatter.formatCellValue(sheet.getRow(i).getCell(3)));
            }

            }catch(FileNotFoundException IOE){
                System.out.println("文件不在正确的位置（the file is not found in the location）");

            }catch(IOException IOE){
                System.out.println("Excel的文件内容不正确（the content of the excel is not correct）");
            }

        }

我已经解决了这个问题，感谢XtremeBaumer和Gagravarr。

原因：因为JVM不支持Character，我创建了这样一个转换器，它可以在使用独占字符时调用可用的字符集。
方法：首先在META-INF/services文件夹中创建一个名为java.nio.charset.spi.CharsetProvider的文件，然后在project文件夹中创建ChineseCharsetProvider.java。

import java.nio.charset.Charset;
import java.nio.charset.spi.CharsetProvider;
import java.util.Collections;
import java.util.Iterator;

public class ChineseCharsetProvider extends CharsetProvider {
    private static final String GB2312 = "GB2312";
    private static final String BIG5 = "Big5";
    private static final String GBK = "GBK";

    @Override
    public Iterator<Charset> charsets() {
        return Collections.emptyIterator();
    }

    @Override
    public Charset charsetForName(String charsetName) {
        if (GB2312.equalsIgnoreCase(charsetName) || BIG5.equalsIgnoreCase(charsetName))
            return Charset.forName(GBK);
        return Charset.defaultCharset();
    }
}
