我将libreoffice服务部署到公共服务器上,成功启动并打开端口后,在我的项目上调用该服务,当我使用其execute方法时,报错:

File tempFile = File.createTempFile("temp", ".pdf");
converter.convert(file).to(tempFile).execute();
outputToResponse(tempFile, "application/pdf");
}
当我调试这条线时,
converter.convert(file).to(tempFile).execute();
报错了,怎么回事?我应该怎么办?帮帮我,谢谢!
此外,当我在笔记本电脑上部署 libreoffice 服务时,一切正常! 我想知道文件传输过程是否有问题,我不确定,你有什么建议?
再次感谢!
这个问题解决了吗?我和你的问题几乎一样,我在同事电脑上启动libreoffice服务,是windows系统
