问题描述
对远程服务器执行 SFTP 时出现此异常
以下是异常的堆栈跟踪
java.io.IOException: Trying to upload file Test.pdf to path /MyFolder/NewTest/Test.pdf but that is a directory
at net.schmizz.sshj.sftp.SFTPFileTransfer$Uploader.prepareFile(SFTPFileTransfer.java:310)
at net.schmizz.sshj.sftp.SFTPFileTransfer$Uploader.uploadFile(SFTPFileTransfer.java:228)
at net.schmizz.sshj.sftp.SFTPFileTransfer$Uploader.upload(SFTPFileTransfer.java:183)
at net.schmizz.sshj.sftp.SFTPFileTransfer$Uploader.access$100(SFTPFileTransfer.java:166)
at net.schmizz.sshj.sftp.SFTPFileTransfer.upload(SFTPFileTransfer.java:64)
at net.schmizz.sshj.sftp.SFTPClient.put(SFTPClient.java:244)
以下是正在使用的代码片段
String localFile = "D:/SFTPFiles/Test.pdf";
String remoteFilePath = "/MyFolder/NewTest";
SSHClient sshClient = new SSHClient();
sshClient.addHostkeyverifier(new Promiscuousverifier());
sshClient.connect(remoteHost);
sshClient.authPassword(downloadUserName,password);
SFTPClient sftpClient = sshClient.newSFTPClient();
FileSystemFile fileSystemFile = new FileSystemFile(localFile);
sftpClient.put(fileSystemFile,remoteFilePath);
sftpClient.close();
sshClient.disconnect();
我已经检查并确保本地服务器上的文件存在。远程服务器上的目录也存在。也尝试过使用 StatefulSFTPClient。远程服务器上也不存在与文件名同名的目录。
详细日志：

SFTPClient.put 的 dest 参数是文件的路径，而不是目标目录的路径。错误信息对此相当清楚。
所以，像这样：
String remoteFilePath = "/MyFolder/NewTest/Test.pdf";
