如何修改 net.schmizz.sshj 日志记录级别？

Question

到目前为止我的代码可以更改默认配置的记录器级别或禁用它吗 [

Config config = new DefaultConfig();
config.setKeepAliveProvider(KeepAliveProvider.KEEP_ALIVE);
SSHClient sshClient = new SSHClient(config);

当我尝试上面的代码时，我遇到了这些问题：

[main] WARN net.schmizz.sshj.DefaultConfig - Illegal key size
[main] WARN net.schmizz.sshj.DefaultConfig - Illegal key size
[main] WARN net.schmizz.sshj.DefaultConfig - Illegal key size

SSHJ 使用 slf4j 日志记录 API。这意味着您可以使用任何实现 slf4j 的日志记录实现来配置它。通常这是 logback 记录器。

您可以通过添加 logback.xml 文件来配置它，例如包含以下配置：

<configuration>

  <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <encoder>
      <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%.-20thread] %-5level %logger{36} - %msg%n</pattern>
    </encoder>
  </appender>

  <root level="info">
    <appender-ref ref="STDOUT"/>
  </root>

  <logger name="net.schmizz.sshj" level="error"/>

</configuration>

顺便说一句，您看到这些消息的原因是您运行没有无限强度的加密扩展。
