java - 如何使用 Ganymed SSH-2 启用完整日志记录

Question

我正在开发一个使用 Ganymed SSH-2 执行 ssh 命令的 java 应用程序

我需要为每个命令序列生成完整的日志，例如zip 文件传输、解压缩、压缩等。

搜索了 ch.ethz.ssh2.log.Logger 的源代码后，我可以将 boolean 值 public static volatile boolean enabled = false; 设置为 true

这提供了以下输出

Mar 05, 2015 10:17:25 AM ch.ethz.ssh2.log.Logger info
INFO: kex_algo=diffie-hellman-group-exchange-sha1
Mar 05, 2015 10:17:25 AM ch.ethz.ssh2.log.Logger info
INFO: server_host_key_algo=ssh-rsa
Mar 05, 2015 10:17:25 AM ch.ethz.ssh2.log.Logger info
INFO: enc_algo_client_to_server=aes128-ctr
Mar 05, 2015 10:17:25 AM ch.ethz.ssh2.log.Logger info
INFO: enc_algo_server_to_client=aes128-ctr
Mar 05, 2015 10:17:25 AM ch.ethz.ssh2.log.Logger info
INFO: mac_algo_client_to_server=hmac-sha1-96
Mar 05, 2015 10:17:25 AM ch.ethz.ssh2.log.Logger info
INFO: mac_algo_server_to_client=hmac-sha1-96
Mar 05, 2015 10:17:25 AM ch.ethz.ssh2.log.Logger info
INFO: comp_algo_client_to_server=none
Mar 05, 2015 10:17:25 AM ch.ethz.ssh2.log.Logger info
INFO: comp_algo_server_to_client=none

但是我还需要所有级别的日志记录来执行命令，包括文件传输。

如何配置记录器以生成所有可用信息？

Answer 1

回答有点晚，但也许有人仍然需要此信息。

我设法让调试语句像这样可见:

    public void enableFineLogging() {
    try {
        ch.ethz.ssh2.log.Logger.enabled = true;
        String name = "myDynamicFileNamePart";

        FileHandler fileHandler = new FileHandler("./logs/"
                + name + "_SFTP.log", 10000000, 1000, true);
        fileHandler.setLevel(Level.FINE);
        fileHandler.setFormatter(new SimpleFormatter());

        final Logger app = Logger.getLogger("ch.ethz");
        app.setLevel(Level.FINE);
        app.addHandler(fileHandler);
        app.setUseParentHandlers(false);

    } catch (Exception e) {
        // Catchalog
    }
}

结果在文件中:

如果您希望登录控制台，请使用 ConsoleHandler。退出日志记录后，还需要考虑使用 fileHandler.close() 关闭日志文件。

通过从 SEVERE、WARNING、INFO、CONFIG、FINE、FINER、FINEST、ALL 中进行选择来调整日志级别
