Java vfs2 FileSystemException私钥无效.如何解决

Question

在我的springboot应用程序中，我正在将一个文件传输到sftp。我只想用用户名和密码进行身份验证。然而，我的java代码仍在寻找要发送的私钥，我得到了以下错误。我该如何解决以下错误。我需要对java类进行哪些更改？

原因：org.apache.commons.fs2.FileSystemException：无法从"加载私钥/用户/123456/.ssh/id_rsa"；。

引起原因：com.jcraf.JSchException：私钥无效：[B@180bc464

这是我的代码：

StandardFileSystemManager manager = new StandardFileSystemManager();
String serverAddress = "test.rebex.net";
String userId = "demo";
String password = "password";
String remoteDirectory = "/IN";
String filepath = "/Users/1234/Documents/TestNotes.txt";
File file = new File(filepath);
manager.init();
FileSystemOptions opts = new FileSystemOptions();
SftpFileSystemConfigBuilder.getInstance().setStrictHostKeyChecking(opts, "no");
SftpFileSystemConfigBuilder.getInstance().setUserDirIsRoot(opts, true);
SftpFileSystemConfigBuilder.getInstance().setTimeout(opts, 10000);
String sftpUri = "sftp://" + userId + ":" + password +  "@" + serverAddress + "/" + remoteDirectory + filepath;
FileObject localFile = manager.resolveFile(file.getAbsolutePath());
FileObject remoteFile = manager.resolveFile(sftpUri, opts);
remoteFile.copyFrom(localFile, Selectors.SELECT_SELF);
System.out.println("File upload successful");

Answer 1

只需以下一行代码即可解决：

SftpFileSystemConfigBuilder.getInstance().setIdentities(opts, new File[0]);
