写入 XLSX 文件 (POI) 时 JVM 崩溃

Question

JVM 在尝试写入 .xlsx 文件时崩溃。我也在使用 POI(XSSF)。 代码中的错误位置点是写method--> workBook.write(fileOutputStream);

在控制台我得到..

A fatal error has been detected by the Java Runtime Environment:

Answer 1

我为此找到的解决方案，并且我一直在寻找一段时间，是确保您不要使用用于打开 FileOutputStream 的 File 打开您的 Workbook 到保存Workbook。而是使用FileInputStream 打开Workbook。

这样的东西可以完美运行

        File inputFile = new File("Your-Path");
        this.inputStream = new FileInputStream(inputFile);
        this.opc = OPCPackage.open(this.inputStream);
        this.workbook = WorkbookFactory.create(opc);

...

        this.outputStream = new FileOutputStream(inputFile);
        this.workbook.write(this.outputStream);

不要忘记关闭每个打开的流和OPCPackage。

Answer 2

其他解决方案都不适合我。我只需要对我的 Excel 文件进行只读访问，并且设置只读标志对我有用：

Workbook wb = new XSSFWorkbook(OPCPackage.open(file, PackageAccess.READ));
Workbook wb = new HSSFWorkbook(new POIFSFileSystem(file, true));

Answer 3

使用 OPCPackage 并没有为我修复 JVM 崩溃，但使用 WorkbookFactory 可以。如果您查看POI Busy Developers Guide，他们提供了读取和写入相同 Excel 文件的示例。

File excelFile = new File("workbook.xlsx");

InputStream inp = new FileInputStream(excelFile);
Workbook wb = WorkbookFactory.create(inp);

FileOutputStream fileOut = new FileOutputStream(excelFile);
wb.write(fileOut);
fileOut.close();

使用 Apache POI 3.13 版、Java 1.8
