使用ssh私钥连接会话时出错

Question

我是新手，所以任何帮助将不胜感激。我正在尝试使用私有ssh密钥和JSch连接到生产服务器，代码是：

private static Logger log = Logger.getLogger(SSHKeyConnector.class);

private final static String HOST_KEY_CHECKING           = "StrictHostKeyChecking";
private final static String HOST_KEY_CHECKING_OPTION    = "no";
private final static String AUTHENTICATION              = "PreferredAuthentications";
private final static String AUTHENTICATION_STYLE        = "publickey,keyboard-interactive,password";
private Session      session;

public SSHKeyConnector() {}

public Session createSession( DataTransferParameterCollection parameters ) throws RemoteAccessException {

    String  host        = parameters.getHostname();
    int     port        = parameters.getPort();
    String  user        = parameters.getHostUser();
    String  password    = parameters.getHostPassword();
    String  keyFile     = parameters.getKeyDirectory() + "id_rsa";

    JSch jsch = new JSch();

    try {
        log.debug("Create an ssh connection to [" + host + "][" + port + "] as user [" + user + "]");

        jsch.addIdentity( keyFile );
        log.debug("Key file added to session");

        session = jsch.getSession( user, host, port );
        session.setConfig(AUTHENTICATION, AUTHENTICATION_STYLE);
        Properties config = new Properties();
        config.put("StrictHostKeyChecking", "no");

        session.setConfig(config);
        session.setPassword( password );
        session.connect();
        log.debug("Remote session connected");

        return session;
    }
    catch ( JSchException je ) {
        log.debug("CreateSession failed: " + je.getCause() );
        je.printStackTrace();
        throw new RemoteAccessException( "CreateSession failed: " + je.getCause());
    }
}

当我运行这个时，我仍然收到身份验证错误，我在StackOverflow上检查了很多帖子，但看不出有什么问题

感谢您的回复，我通过改变它来实现这一点

jsch.addIdentity（密钥文件）;

至

jsch.addIdentity（密钥文件，密码）;

并已删除

session.setPassword（密码）;

它现在工作正常
