如何将字节数组( PDF文件)放入剪贴板

        byte[] pdfBytes = getPDFBytes();

        try {
            // 将字节数组转换为InputStream
            InputStream inputStream = new ByteArrayInputStream(pdfBytes);

            // 获取系统剪贴板
            Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();

            // 创建一个DataFlavor对象，用于表示二进制数据
            DataFlavor flavor = new DataFlavor("application/pdf", "PDF");

            // 将InputStream放入剪贴板
            clipboard.setContents(new java.awt.datatransfer.Transferable() {
                @Override
                public DataFlavor[] getTransferDataFlavors() {
                    return new DataFlavor[]{flavor};
                }

                @Override
                public boolean isDataFlavorSupported(DataFlavor flavor) {
                    return flavor.equals(this.flavor);
                }

                @Override
                public Object getTransferData(DataFlavor flavor) throws UnsupportedFlavorException, IOException {
                    if (flavor.equals(this.flavor)) {
                        return inputStream;
                    } else {
                        throw new UnsupportedFlavorException(flavor);
                    }
                }
            }, null);

            System.out.println("PDF文件已成功放入剪贴板");
        } catch (UnsupportedFlavorException | IOException e) {
            e.printStackTrace();
        }
    }

    // 模拟获取PDF文件的字节数组
    private static byte[] getPDFBytes() {
        // 这里应该是从文件或其他来源获取PDF字节数组的逻辑
        return new byte[0];
    }
}
