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

在控制台我得到..

我找到的解决方案,我一直在寻找一段时间,是为了确保你不打开你Workbook用File你打开它FileOutputStream来保存Workbook.相反,使用a FileInputStream来打开Workbook.

像这样的东西将完美无缺

        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.
