下面是我的 java 1.8 程序的示例部分。尝试进行身份验证时似乎失败了。它通过多种身份验证方法，然后宣布其用完。我想从 sshj 库中查看调试信息，以帮助我确定失败的原因：- 用户名、密钥交换或其他内容。我熟悉 log4j，我可以在我的代码中放置日志记录语句，但是我找不到一个示例（简单易懂），它告诉我如何将 log4j 连接到 sfl4j，然后告诉 sshj 使用记录器。

        SSHClient sshClient = new SSHClient();

        try
        {
            
            String username = "testuser";
            File privateKey = new File("/mykeys/keyname");
            KeyProvider keys;
            
            sshClient.addHostKeyVerifier(new PromiscuousVerifier());
            
            keys = sshClient.loadKeys(privateKey.getPath());
            
            sshClient.connect("1.2.3.4", 22);
            
            sshClient.authPublickey(username, keys);

            SFTPClient sftpClient = sshClient.newSFTPClient();
            
            sftpClient.put("./send/file1.xml", "file1.xml");
            

            sshClient.close();
        }

        catch (UserAuthException e)
        {
            // TODO Auto-generated catch block
            System.out.println(e.getMessage());
        }
        catch (TransportException e)
        {
            // TODO Auto-generated catch block
            System.out.println(e.getMessage());
        }
        catch (IOException e)
        {
            // TODO Auto-generated catch block
            System.out.println(e.getMessage());
        }

到 pom.xml

并创建一个 log4j.proerties 文件对我有用：

# Define the root logger with appender file  
log = ssh-test.log
log4j.rootLogger = DEBUG, FILE  

# Define the file appender  
log4j.appender.FILE=org.apache.log4j.FileAppender  
log4j.appender.FILE.File=${log}/log.out  

# Define the layout for file appender  
log4j.appender.FILE.layout=org.apache.log4j.PatternLayout  
log4j.appender.FILE.layout.conversionPattern=%m%n
