java.lang.ClassNotFoundException : org. apache.poi.poifs.crypt.agile.AgileEncryptionInfoBuilder

Question

我正在使用 Apache Poi.3.10-FINAL jar 生成 Excel 工作表。我尝试使用下面的代码进行密码保护。我收到这样的错误。

Exception in thread "main" org.apache.poi.EncryptedDocumentException: java.lang.ClassNotFoundException: org.apache.poi.poifs.crypt.agile.AgileEncryptionInfoBuilder

... 3 more

代码:取自 link.

POIFSFileSystem fs = new POIFSFileSystem();
    EncryptionInfo info = new EncryptionInfo(fs, EncryptionMode.agile);

    Encryptor enc = info.getEncryptor();
    enc.confirmPassword("s3cr3t");

    OPCPackage opc = OPCPackage.open(new File("c:/test/excel.xlsx"), PackageAccess.READ_WRITE);
    OutputStream os = enc.getDataStream(fs);
    opc.save(os);
    opc.close();

    FileOutputStream fos = new FileOutputStream("c:/test/excel.xlsx");
    fs.writeFilesystem(fos);
    fos.close();    

我尝试搜索缺少的类 org.apache.poi.poifs.crypt.agile.AgileEncryptionInfoBuilder 但找不到。

感谢任何帮助。提前致谢。

您还需要 poi-ooxml-3.10.FINAL。下载并将其添加到您的类路径中。
