java - 写入 XLSX 文件 (POI) 时 JVM 崩溃

Question

JVM 在尝试写入 .xlsx 文件时崩溃。我正在使用 POI(XSSF) 来做同样的事情。 代码中出错的位置点是write method--> workBook.write(fileOutputStream);

在控制台上我得到..

我为此找到的解决方案(我已经寻找了一段时间)是确保您不会使用 File 打开您的 Workbook用于打开 FileOutputStream 以保存 Workbook。相反，使用 FileInputStream 打开 Workbook。

像这样的东西会完美地工作

        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。
