Question

在将文件上传到FTPS服务器时，我遇到了一个严重的（怪异的）问题。

我必须上传JSON文件，其中一些确实很小（小于5kB）。这些文件没有问题，我可以成功上传它们。

但是当上传“更大”的文件（不是很大，超过30kb）时，会显示此错误：

我已经尝试过outpustream，但遇到了同样的错误。还尝试使用WinSCP手动上传，并且可以正常工作，因此这不是权限问题。

Answer 1

我设法解决了这个问题。发生的情况是FTPS服务器正在使用SSL v3协议进行连接，并且由于某些安全漏洞，java弃用了该协议。

最好的解决方案是更改FTP服务器的协议

FTPSClient仅在上传微不足道的文件时成功
