java.io.EOFException：使用 Apache POI 的 ZLIB 输入流意外结束

Question

我尝试使用 Apache POI 创建 Excel 数据透视表。
目前，当我尝试在工作簿workbook.write(fileOut); 中写入数据时出现异常

org.apache.poi.ooxml.POIXMLException: java.io.EOFException: Unexpected ZLIB 输入流结束

有类的代码：

public class PivotTable {



public static void createPivotTable(String pathToWorkbook, String sheetName) throws IOException {

    Workbook workbook = new XSSFWorkbook(pathToWorkbook);

    XSSFSheet sheet = (XSSFSheet) workbook.getSheet(sheetName);

    int firstRowInd = sheet.getFirstRowNum();
    int lastRowInd = sheet.getLastRowNum();
    int firstCellInd = sheet.getRow(0).getFirstCellNum();
    int lastCellInd = sheet.getRow(0).getLastCellNum() - 1;

    //Specifying top left ant the bottom right of the table data
    CellReference topLeft = new CellReference(firstRowInd, firstCellInd);
    CellReference botRight = new CellReference(lastRowInd, lastCellInd);

    //The area of data in table
    AreaReference aref = new AreaReference(topLeft, botRight, SpreadsheetVersion.EXCEL2007);

    //Position of the pivot table
    CellReference pos = new CellReference(firstRowInd + 4, lastCellInd + 1);

    //Creating the pivot table
    XSSFPivotTable pivotTable = sheet.createPivotTable(aref, pos);


    pivotTable.addRowLabel(0);
    pivotTable.addRowLabel(2);
    pivotTable.addColLabel(3);

    FileOutputStream fileOut = new FileOutputStream(pathToWorkbook);
    workbook.write(fileOut);
    fileOut.close();


}

还有StackTrace的异常：

Answer 1

我遇到了同样的问题，我通过换行解决了：

Workbook workbook = new XSSFWorkbook(pathToWorkbook);

到：

Workbook workbook = new XSSFWorkbook(new FileInputStream(pathToWorkbook));

希望对您有所帮助！ :)

Answer 2

很确定问题是您覆盖了文件。尝试保存到不同的路径。如果您仍然想覆盖文件，请保存到其他内容，删除原始文件，然后将您写入的文件重命名到位：

try (FileOutputStream fileOut = new FileOutputStream(pathToWorkbook + ".new")) {
    workbook.write(fileOut);
}
Files.delete(Paths.get(pathToWorkbook));
Files.move(Paths.get(pathToWorkbook + ".new"), Paths.get(pathToWorkbook));

Answer 3

workbook.write() 方法中似乎有一个小错误。我找到了 2 个解决方法。 首先是为 FileOutputStream 指定任何另一个（虚拟）文件名。当工作簿关闭时，两个文件都将被填充。 其次，更好的是为 workbook.write() 方法指定虚拟 OutputStream：

OutputStream dummyOutputStream = new OutputStream() {
            @Override
            public void write(int b) throws IOException {

            }
        };
        workbook.write(dummyOutputStream);
        dummyOutputStream.close();
        workbook.close();
