java - spring boot中生成密码加密的excel文件时遇到 no such file or directory 错误

Question

以下代码用于创建受密码保护的 Excel 文件。

    1.POIFSFileSystem fs = new POIFSFileSystem();    2.EncryptionInfo info = new EncryptionInfo(EncryptionMode.agile);    3.Encryptor enc = info.getEncryptor();    4.enc.confirmPassword("pass");    5.Workbook workbook = new XSSFWorkbook();    6.Sheet sheet = workbook.createSheet("sheet1");    7.sheet.createRow(0).createCell(0).setCellValue("test123");    8.OutputStream encos = enc.getDataStream(fs);    9.workbook.write(encos);    10.workbook.close();    11.OutputStream os = new FileOutputStream("provawrite.xlsx");    12.fs.writeFilesystem(os);    13.os.close();

I am using the below dependencies.

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>        
            <groupId>org.apache.poi</groupId>       
            <artifactId>poi-ooxml</artifactId>      
            <version>3.12</version>     
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
            <scope>provided</scope>
        </dependency>

这段代码在 Spring Tool Suite (localhost) 中工作得很好，但是当我将相同的代码推送到外部服务器中并运行它时，它显示以下错误。 (此错误是在第 8 行生成的)
